This file describes various problems that have been encountered
|
||
in compiling, installing and running GNU Emacs.
|
||
|
||
* Getting a Meta key on the FreeBSD console
|
||
|
||
By default, neither Alt nor any other key acts as a Meta key on
|
||
FreeBSD, but this can be changed using kbdcontrol(1). Dump the
|
||
current keymap to a file with the command
|
||
|
||
$ kbdcontrol -d >emacs.kbd
|
||
|
||
Edit emacs.kbd, and give the key you want to be the Meta key the
|
||
definition `meta'. For instance, if your keyboard has a ``Windows''
|
||
key with scan code 105, change the line for scan code 105 in emacs.kbd
|
||
to look like this
|
||
|
||
105 meta meta meta meta meta meta meta meta O
|
||
|
||
to make the Windows key the Meta key. Load the new keymap with
|
||
|
||
$ kbdcontrol -l emacs.kbd
|
||
|
||
* Emacs' xterm-mouse-mode doesn't work on the Gnome terminal.
|
||
|
||
A symptom of this bug is that double-clicks insert a control sequence
|
||
into the buffer. The reason this happens is an apparent
|
||
incompatibility of the Gnome terminal with Xterm, which also affects
|
||
other programs using the Xterm mouse interface. A problem report has
|
||
been filed.
|
||
|
||
* Emacs pauses for several seconds when changing the default font
|
||
|
||
This has been reported for fvwm 2.2.5 and the window manager of KDE
|
||
2.1. The reason for the pause is Xt waiting for a ConfigureNotify
|
||
event from the window manager, which the window manager doesn't send.
|
||
Xt stops waiting after a default timeout of usually 5 seconds.
|
||
|
||
A workaround for this is to add something like
|
||
|
||
emacs.waitForWM: false
|
||
|
||
to your X resources. Alternatively, add `(wait-for-wm . nil)' to a
|
||
frame's parameter list, like this:
|
||
|
||
(modify-frame-parameters nil '((wait-for-wm . nil)))
|
||
|
||
(this should go into your `.emacs' file).
|
||
|
||
* Underlines appear at the wrong position.
|
||
|
||
This is caused by fonts having a wrong UNDERLINE_POSITION property.
|
||
An example is the font 7x13 on XFree prior to version 4.1. To
|
||
circumvent this problem, set x-use-underline-position-properties to
|
||
nil in your .emacs.
|
||
|
||
* Building Emacs with GCC 2.9x fails in the `src' directory.
|
||
|
||
This may happen if you use a development version of GNU `cpp' from one
|
||
of the GCC snapshots between Oct 2000 and Feb 2001, or from a released
|
||
version of GCC newer than 2.95.2 which was prepared around those
|
||
dates. The preprocessor in those versions expands ".." into ". .",
|
||
which breaks relative file names that reference the parent directory.
|
||
|
||
The solution is to make sure the preprocessor is run with the
|
||
`-traditional' option. (The `configure' script does that
|
||
automatically.)
|
||
|
||
Note that this problem does not pertain to the MS-Windows port of
|
||
Emacs, since it doesn't use the preprocessor to generate Makefiles.
|
||
|
||
* Building the MS-Windows port with Cygwin GCC can fail.
|
||
|
||
Emacs may not build using recent Cygwin builds of GCC, such as Cygwin
|
||
version 1.1.8, using the default configure settings. It appears to be
|
||
necessary to specify the -mwin32 flag when compiling, and define
|
||
__MSVCRT__, like so:
|
||
|
||
configure --with-gcc --cflags -mwin32 --cflags -D__MSVCRT__
|
||
|
||
* Building the MS-Windows port with Leim fails in the `leim' directory.
|
||
|
||
The error message might be something like this:
|
||
|
||
Converting d:/emacs-21.1/leim/CXTERM-DIC/4Corner.tit to quail-package...
|
||
Invalid ENCODE: value in TIT dictionary
|
||
NMAKE : fatal error U1077: '"../src/obj-spd/i386/emacs.exe"' : return code
|
||
'0xffffffff'
|
||
Stop.
|
||
|
||
This can happen if the Leim distribution is unpacked with a program
|
||
which converts the `*.tit' files to DOS-style CR-LF text format. The
|
||
`*.tit' files in the leim/CXTERM-DIC directory require Unix-style line
|
||
endings to compile properly, because Emacs reads them without any code
|
||
or EOL conversions.
|
||
|
||
The solution is to make sure the program used to unpack Leim does not
|
||
change the files' line endings behind your back. The GNU FTP site has
|
||
in the `/gnu/emacs/windows' directory a program called `djtarnt.exe'
|
||
which can be used to unpack `.tar.gz' and `.zip' archives without
|
||
mangling them.
|
||
|
||
* JPEG images aren't displayed.
|
||
|
||
This has been reported when Emacs is built with jpeg-6a library.
|
||
Upgrading to jpeg-6b solves the problem.
|
||
|
||
* Building `ctags' for MS-Windows with the MinGW port of GCC fails.
|
||
|
||
This might happen due to a bug in the MinGW header assert.h, which
|
||
defines the `assert' macro with a trailing semi-colon. The following
|
||
patch to assert.h should solve this:
|
||
|
||

|
||
|
||
|
||
* When using Xaw3d scroll bars without arrows, the very first mouse
|
||
click in a scroll bar might be ignored by the scroll bar widget. This
|
||
is probably a bug in Xaw3d; when Xaw3d is compiled with arrows, the
|
||
problem disappears.
|
||
|
||
* Clicking C-mouse-2 in the scroll bar doesn't split the window.
|
||
|
||
This currently doesn't work with scroll-bar widgets (and we don't know
|
||
a good way of implementing it with widgets). If Emacs is configured
|
||
--without-toolkit-scroll-bars, C-mouse-2 on the scroll bar does work.
|
||
|
||
* Colors are not available on a tty or in xterm.
|
||
|
||
Emacs 21 supports colors on character terminals and terminal
|
||
emulators, but this support relies on the terminfo or termcap database
|
||
entry to specify that the display supports color. Emacs looks at the
|
||
"Co" capability for the terminal to find out how many colors are
|
||
supported; it should be non-zero to activate the color support within
|
||
Emacs. (Most color terminals support 8 or 16 colors.) If your system
|
||
uses terminfo, the name of the capability equivalent to "Co" is
|
||
"colors".
|
||
|
||
In addition to the "Co" capability, Emacs needs the "op" (for
|
||
``original pair'') capability, which tells how to switch the terminal
|
||
back to the default foreground and background colors. Emacs will not
|
||
use colors if this capability is not defined. If your terminal entry
|
||
doesn't provide such a capability, try using the ANSI standard escape
|
||
sequence \E[00m (that is, define a new termcap/terminfo entry and make
|
||
it use your current terminal's entry plus \E[00m for the "op"
|
||
capability).
|
||
|
||
Finally, the "NC" capability (terminfo name: "ncv") tells Emacs which
|
||
attributes cannot be used with colors. Setting this capability
|
||
incorrectly might have the effect of disabling colors; try setting
|
||
this capability to `0' (zero) and see if that helps.
|
||
|
||
Emacs uses the database entry for the terminal whose name is the value
|
||
of the environment variable TERM. With `xterm', a common terminal
|
||
entry that supports color is `xterm-color', so setting TERM's value to
|
||
`xterm-color' might activate the color support on an xterm-compatible
|
||
emulator.
|
||
|
||
Some modes do not use colors unless you turn on the Font-lock mode.
|
||
Some people have long ago set their `~/.emacs' files to turn on
|
||
Font-lock on X only, so they won't see colors on a tty. The
|
||
recommended way of turning on Font-lock is by typing "M-x
|
||
global-font-lock-mode RET" or by customizing the variable
|
||
`global-font-lock-mode'.
|
||
|
||
* Problems in Emacs built with LessTif.
|
||
|
||
The problems seem to depend on the version of LessTif and the Motif
|
||
emulation for which it is set up.
|
||
|
||
Only the Motif 1.2 emulation seems to be stable enough in LessTif.
|
||
Lesstif 0.92-17's Motif 1.2 emulation seems to work okay on FreeBSD.
|
||
On GNU/Linux systems, lesstif-0.92.6 configured with "./configure
|
||
--enable-build-12 --enable-default-12" is reported to be the most
|
||
successful. The binary GNU/Linux package
|
||
lesstif-devel-0.92.0-1.i386.rpm was reported to have problems with
|
||
menu placement.
|
||
|
||
On some systems, even with Motif 1.2 emulation, Emacs occasionally
|
||
locks up, grabbing all mouse and keyboard events. We still don't know
|
||
what causes these problems; they are not reproducible by Emacs
|
||
developers.
|
||
|
||
* Known problems with the MS-Windows port of Emacs 21.1.
|
||
|
||
Emacs 21.1 built for MS-Windows doesn't support images, the tool bar,
|
||
and tooltips. Support for these will be added in future versions.
|
||
|
||
Help text that is displayed in a tooltip on other window systems, on
|
||
Windows is printed in the echo area, since tooltips are not yet
|
||
available. Help text for menu items is not displayed at all.
|
||
|
||
There are problems with display if the variable `redisplay-dont-pause'
|
||
is set to nil (w32-win.el sets it to t by default, to avoid these
|
||
problems). The problems include:
|
||
|
||
. No redisplay as long as help echo is displayed in the echo area,
|
||
e.g. if the mouse is on a mouse-sensitive part of the mode line.
|
||
|
||
. When the mode line is dragged with the mouse, multiple copies of the
|
||
mode line are left behind, until the mouse button is released and
|
||
the next input event occurs.
|
||
|
||
. Window contents are not updated when text is selected by dragging
|
||
the mouse, and the mouse is dragged below the bottom line of the
|
||
window. When the mouse button is released, the window display is
|
||
correctly updated.
|
||
|
||
Again, these problems only occur if `redisplay-dont-pause' is nil.
|
||
|
||
Emacs can sometimes abort when non-ASCII text, possibly with null
|
||
characters, is copied and pasted into a buffer.
|
||
|
||
An inactive cursor remains in an active window after the Windows
|
||
Manager driven switch of the focus, until a key is pressed.
|
||
|
||
Windows 2000 input methods are not recognized by Emacs (as of v21.1).
|
||
These input methods cause the keyboard to send characters encoded in
|
||
the appropriate coding system (e.g., ISO 8859-1 for Latin-1
|
||
characters, ISO 8859-8 for Hebrew characters, etc.). To make this
|
||
work, set the keyboard coding system to the appropriate value after
|
||
you activate the Windows input method. For example, if you activate
|
||
the Hebrew input method, type "C-x RET k iso-8859-8 RET". (Emacs
|
||
ought to recognize the Windows language-change event and set up the
|
||
appropriate keyboard encoding automatically, but it doesn't do that
|
||
yet.)
|
||
|
||
Multilingual text put into the Windows 2000 clipboard by Windows
|
||
applications cannot be safely pasted into Emacs (as of v21.1). This
|
||
is because Windows 2000 uses Unicode to represent multilingual text,
|
||
but Emacs does not yet support Unicode well enough to decode it. This
|
||
means that Emacs can only interchange non-ASCII text with other
|
||
Windows 2000 programs if the characters are in the system codepage.
|
||
Reportedly, a partial solution is to install the Mule-UCS package and
|
||
set selection-coding-system to utf-16-le-dos.
|
||
|
||
* The `configure' script doesn't find the jpeg library.
|
||
|
||
This can happen because the linker by default only looks for shared
|
||
libraries, but jpeg distribution by default doesn't build and doesn't
|
||
install a shared version of the library, `libjpeg.so'. One system
|
||
where this is known to happen is Compaq OSF/1 (`Tru64'), but it
|
||
probably isn't limited to that system.
|
||
|
||
You can configure the jpeg library with the `--enable-shared' option
|
||
and then rebuild libjpeg. This produces a shared version of libjpeg,
|
||
which you need to install. Finally, rerun the Emacs configure script,
|
||
which should now find the jpeg library. Alternatively, modify the
|
||
generated src/Makefile to link the .a file explicitly.
|
||
|
||
(If you need the static version of the jpeg library as well, configure
|
||
libjpeg with both `--enable-static' and `--enable-shared' options.)
|
||
|
||
* Building Emacs over NFS fails with ``Text file busy''.
|
||
|
||
This was reported to happen when building Emacs on a GNU/Linux system
|
||
(RedHat Linux 6.2) using a build directory automounted from Solaris
|
||
(SunOS 5.6) file server, but it might not be limited to that
|
||
configuration alone. Presumably, the NFS server doesn't commit the
|
||
files' data to disk quickly enough, and the Emacs executable file is
|
||
left ``busy'' for several seconds after Emacs has finished dumping
|
||
itself. This causes the subsequent commands which invoke the dumped
|
||
Emacs excutable to fail with the above message.
|
||
|
||
In some of these cases, a time skew between the NFS server and the
|
||
machine where Emacs is built is detected and reported by GNU Make
|
||
(it says that some of the files have modification time in the future).
|
||
This might be a symptom of NFS-related problems.
|
||
|
||
If the NFS server runs on Solaris, apply the Solaris patch 105379-05
|
||
(Sunos 5.6: /kernel/misc/nfssrv patch). If that doesn't work, or if
|
||
you have a different version of the OS or the NFS server, you can
|
||
force the NFS server to use 1KB blocks, which was reported to fix the
|
||
problem albeit at a price of slowing down file I/O. You can force 1KB
|
||
blocks by specifying the "-o rsize=1024,wsize=1024" options to the
|
||
`mount' command, or by adding ",rsize=1024,wsize=1024" to the mount
|
||
options in the appropriate system configuration file, such as
|
||
`/etc/auto.home'.
|
||
|
||
Alternatively, when Make fails due to this problem, you could wait for
|
||
a few seconds and then invoke Make again. In one particular case,
|
||
waiting for 10 or more seconds between the two Make invocations seemed
|
||
to work around the problem.
|
||
|
||
Similar problems can happen if your machine NFS-mounts a directory
|
||
onto itself. Suppose the Emacs sources live in `/usr/local/src' and
|
||
you are working on the host called `marvin'. Then an entry in the
|
||
`/etc/fstab' file like the following is asking for trouble:
|
||
|
||
marvin:/usr/local/src /usr/local/src ...options.omitted...
|
||
|
||
The solution is to remove this line from `etc/fstab'.
|
||
|
||
* Accented ISO-8859-1 characters are displayed as | or _.
|
||
|
||
Try other font set sizes (S-mouse-1). If the problem persists with
|
||
other sizes as well, your text is corrupted, probably through software
|
||
that is not 8-bit clean. If the problem goes away with another font
|
||
size, it's probably because some fonts pretend to be ISO-8859-1 fonts
|
||
when they are really ASCII fonts. In particular the schumacher-clean
|
||
fonts have this bug in some versions of X.
|
||
|
||
To see what glyphs are included in a font, use `xfd', like this:
|
||
|
||
xfd -fn -schumacher-clean-medium-r-normal--12-120-75-75-c-60-iso8859-1
|
||
|
||
If this shows only ASCII glyphs, the font is indeed the source of the
|
||
problem.
|
||
|
||
The solution is to remove the corresponding lines from the appropriate
|
||
`fonts.alias' file, then run `mkfontdir' in that directory, and then run
|
||
`xset fp rehash'.
|
||
|
||
* Large file support is disabled on HP-UX. See the comments in
|
||
src/s/hpux10.h.
|
||
|
||
* Crashes when displaying uncompressed GIFs with version
|
||
libungif-4.1.0 are resolved by using version libungif-4.1.0b1.
|
||
|
||
* Interrupting Cygwin port of Bash from Emacs doesn't work.
|
||
|
||
Cygwin 1.x builds of the ported Bash cannot be interrupted from the
|
||
MS-Windows version of Emacs. This is due to some change in the Bash
|
||
port or in the Cygwin library which apparently make Bash ignore the
|
||
keyboard interrupt event sent by Emacs to Bash. (Older Cygwin ports
|
||
of Bash, up to b20.1, did receive SIGINT from Emacs.)
|
||
|
||
* The latest released version of the W3 package doesn't run properly
|
||
with Emacs 21 and needs work. However, these problems are already
|
||
fixed in W3's CVS. This patch is reported to make w3-4.0pre.46 work:

|
||
* Unicode characters are not unified with other Mule charsets.
|
||
|
||
As of v21.1, Emacs charsets are still not unified. This means that
|
||
characters which belong to charsets such as Latin-2, Greek, Hebrew,
|
||
etc. and the same characters in the `mule-unicode-*' charsets are
|
||
different characters, as far as Emacs is concerned. For example, text
|
||
which includes Unicode characters from the Latin-2 locale cannot be
|
||
encoded by Emacs with ISO 8859-2 coding system; and if you yank Greek
|
||
text from a buffer whose buffer-file-coding-system is greek-iso-8bit
|
||
into a mule-unicode-0100-24ff buffer, Emacs won't be able to save that
|
||
buffer neither as ISO 8859-7 nor as UTF-8.
|
||
|
||
To work around this, install some add-on package such as Mule-UCS.
|
||
|
||
* The `oc-unicode' package doesn't work with Emacs 21.
|
||
|
||
This package tries to define more private charsets than there are free
|
||
slots now. If the built-in Unicode/UTF-8 support is insufficient,
|
||
e.g. if you need more CJK coverage, use the current Mule-UCS package.
|
||
Any files encoded as emacs-mule using oc-unicode won't be read
|
||
correctly by Emacs 21.
|
||
|
||
* On systems with shared libraries you might encounter run-time errors
|
||
from the dynamic linker telling you that it is unable to find some
|
||
shared libraries, for instance those for Xaw3d or image support.
|
||
These errors mean Emacs has been linked with a library whose shared
|
||
library is not in the default search path of the dynamic linker.
|
||
|
||
On many systems, it is possible to set LD_LIBRARY_PATH in your
|
||
environment to specify additional directories where shared libraries
|
||
can be found.
|
||
|
||
Other systems allow to set LD_RUN_PATH in a similar way, but before
|
||
Emacs is linked. With LD_RUN_PATH set, the linker will include a
|
||
specified run-time search path in the executable.
|
||
|
||
Please refer to the documentation of your dynamic linker for details.
|
||
|
||
* On Solaris 2.7, building Emacs with WorkShop Compilers 5.0 98/12/15
|
||
C 5.0 failed, apparently with non-default CFLAGS, most probably due to
|
||
compiler bugs. Using Sun Solaris 2.7 Sun WorkShop 6 update 1 C
|
||
release was reported to work without problems. It worked OK on
|
||
another system with Solaris 8 using apparently the same 5.0 compiler
|
||
and the default CFLAGS.
|
||
|
||
* Compiling syntax.c with the OPENSTEP 4.2 compiler gcc 2.7.2.1 fails.
|
||
|
||
The compiler was reported to crash while compiling syntax.c with the
|
||
following message:
|
||
|
||
cc: Internal compiler error: program cc1obj got fatal signal 11
|
||
|
||
To work around this, replace the macros UPDATE_SYNTAX_TABLE_FORWARD,
|
||
INC_BOTH, and INC_FROM with functions. To this end, first define 3
|
||
functions, one each for every macro. Here's an example:
|
||
|
||
static int update_syntax_table_forward(int from)
|
||
{
|
||
return(UPDATE_SYNTAX_TABLE_FORWARD(from));
|
||
}/*update_syntax_table_forward*/
|
||
|
||
Then replace all references to UPDATE_SYNTAX_TABLE_FORWARD in syntax.c
|
||
with a call to the function update_syntax_table_forward.
|
||
|
||
* Emacs 20 and later fails to load Lisp files at startup.
|
||
|
||
The typical error message might be like this:
|
||
|
||
"Cannot open load file: fontset"
|
||
|
||
This could happen if you compress the file lisp/subdirs.el. That file
|
||
tells Emacs what are the directories where it should look for Lisp
|
||
files. Emacs cannot work with subdirs.el compressed, since the
|
||
Auto-compress mode it needs for this will not be loaded until later,
|
||
when your .emacs file is processed. (The package `fontset.el' is
|
||
required to set up fonts used to display text on window systems, and
|
||
its loaded very early in the startup procedure.)
|
||
|
||
Similarly, any other .el file for which there's no corresponding .elc
|
||
file could fail to load if it is compressed.
|
||
|
||
The solution is to uncompress all .el files which don't have a .elc
|
||
file.
|
||
|
||
* Attempting to visit remote files via ange-ftp fails.
|
||
|
||
If the error message is "ange-ftp-file-modtime: Specified time is not
|
||
representable", then this could happen when `lukemftp' is used as the
|
||
ftp client. This was reported to happen on Debian GNU/Linux 2.4.3
|
||
with `lukemftp' 1.5-5, but might happen on other systems as well. To
|
||
avoid this problem, switch to using the standard ftp client. On a
|
||
Debian system, type
|
||
|
||
update-alternatives --config ftpd
|
||
|
||
and then choose /usr/bin/netkit-ftp.
|
||
|
||
* On Windows 95/98/ME, subprocesses do not terminate properly.
|
||
|
||
This is a limitation of the Operating System, and can cause problems
|
||
when shutting down Windows. Ensure that all subprocesses are exited
|
||
cleanly before exiting Emacs. For more details, see the FAQ at
|
||
ftp://ftp.gnu.org/gnu/windows/emacs/doc/index.html
|
||
|
||
* Mail sent through Microsoft Exchange in some encodings appears to be
|
||
mangled and is not seen correctly in Rmail or Gnus. We don't know
|
||
exactly what happens, but it isn't an Emacs problem in cases we've
|
||
seen.
|
||
|
||
* After upgrading to a newer version of Emacs, the Meta key stops working.
|
||
|
||
This was reported to happen on a GNU/Linux system distributed by
|
||
Mandrake. The reason is that the previous version of Emacs was
|
||
modified by Mandrake to make the Alt key act as the Meta key, on a
|
||
keyboard where the Windows key is the one which produces the Meta
|
||
modifier. A user who started using a newer version of Emacs, which
|
||
was not hacked by Mandrake, expected the Alt key to continue to act as
|
||
Meta, and was astonished when that didn't happen.
|
||
|
||
The solution is to find out what key on your keyboard produces the Meta
|
||
modifier, and use that key instead. Try all of the keys to the left
|
||
and to the right of the space bar, together with the `x' key, and see
|
||
which combination produces "M-x" in the echo area. You can also use
|
||
the `xmodmap' utility to show all the keys which produce a Meta
|
||
modifier:
|
||
|
||
xmodmap -pk | egrep -i "meta|alt"
|
||
|
||
A more convenient way of finding out which keys produce a Meta modifier
|
||
is to use the `xkbprint' utility, if it's available on your system:
|
||
|
||
xkbprint 0:0 /tmp/k.ps
|
||
|
||
This produces a PostScript file `/tmp/k.ps' with a picture of your
|
||
keyboard; printing that file on a PostScript printer will show what
|
||
keys can serve as Meta.
|
||
|
||
The `xkeycaps' also shows a visual representation of the current
|
||
keyboard settings. It also allows to modify them.
|
||
|
||
* On OSF/Dec Unix/Tru64/<whatever it is this year> under X locally or
|
||
remotely, M-SPC acts as a `compose' key with strange results. See
|
||
keyboard(5).
|
||
|
||
Changing Alt_L to Meta_L fixes it:
|
||
% xmodmap -e 'keysym Alt_L = Meta_L Alt_L'
|
||
% xmodmap -e 'keysym Alt_R = Meta_R Alt_R'
|
||
|
||
* Error "conflicting types for `initstate'" compiling with GCC on Irix 6.
|
||
|
||
Install GCC 2.95 or a newer version, and this problem should go away.
|
||
It is possible that this problem results from upgrading the operating
|
||
system without reinstalling GCC; so you could also try reinstalling
|
||
the same version of GCC, and telling us whether that fixes the problem.
|
||
|
||
* On Solaris 7, Emacs gets a segmentation fault when starting up using X.
|
||
|
||
This results from Sun patch 107058-01 (SunOS 5.7: Patch for
|
||
assembler) if you use GCC version 2.7 or later.
|
||
To work around it, either install patch 106950-03 or later,
|
||
or uninstall patch 107058-01, or install the GNU Binutils.
|
||
Then recompile Emacs, and it should work.
|
||
|
||
* With X11R6.4, public-patch-3, Emacs crashes at startup.
|
||
|
||
Reportedly this patch in X fixes the problem.

* Emacs crashes on Irix 6.5 on the SGI R10K, when compiled with GCC.
|
||
|
||
This seems to be fixed in GCC 2.95.
|
||
|
||
* Emacs crashes in utmpname on Irix 5.3.
|
||
|
||
This problem is fixed in Patch 3175 for Irix 5.3.
|
||
It is also fixed in Irix versions 6.2 and up.
|
||
|
||
* The S-C-t key combination doesn't get passed to Emacs on X.
|
||
|
||
This happens because some X configurations assign the Ctrl-Shift-t
|
||
combination the same meaning as the Multi_key. The offending
|
||
definition is in the file `...lib/X11/locale/iso8859-1/Compose'; there
|
||
might be other similar combinations which are grabbed by X for similar
|
||
purposes.
|
||
|
||
We think that this can be countermanded with the `xmodmap' utility, if
|
||
you want to be able to bind one of these key sequences within Emacs.
|
||
|
||
* On Solaris, CTRL-t is ignored by Emacs when you use
|
||
the fr.ISO-8859-15 locale (and maybe other related locales).
|
||
|
||
You can fix this by editing the file:
|
||
|
||
/usr/openwin/lib/locale/iso8859-15/Compose
|
||
|
||
Near the bottom there is a line that reads:
|
||
|
||
Ctrl<t> <quotedbl> <Y> : "\276" threequarters
|
||
|
||
that should read:
|
||
|
||
Ctrl<T> <quotedbl> <Y> : "\276" threequarters
|
||
|
||
Note the lower case <t>. Changing this line should make C-t work.
|
||
|
||
* Emacs on Digital Unix 4.0 fails to build, giving error message
|
||
Invalid dimension for the charset-ID 160
|
||
|
||
This is due to a bug or an installation problem in GCC 2.8.0.
|
||
Installing a more recent version of GCC fixes the problem.
|
||
|
||
* Buffers from `with-output-to-temp-buffer' get set up in Help mode.
|
||
|
||
Changes in Emacs 20.4 to the hooks used by that function cause
|
||
problems for some packages, specifically BBDB. See the function's
|
||
documentation for the hooks involved. BBDB 2.00.06 fixes the problem.
|
||
|
||
* Under X, C-v and/or other keys don't work.
|
||
|
||
These may have been intercepted by your window manager. In
|
||
particular, AfterStep 1.6 is reported to steal C-v in its default
|
||
configuration. Various Meta keys are also likely to be taken by the
|
||
configuration of the `feel'. See the WM's documentation for how to
|
||
change this.
|
||
|
||
* When using Exceed, fonts sometimes appear too tall.
|
||
|
||
When the display is set to an Exceed X-server and fonts are specified
|
||
(either explicitly with the -fn option or implicitly with X resources)
|
||
then the fonts may appear "too tall". The actual character sizes are
|
||
correct but there is too much vertical spacing between rows, which
|
||
gives the appearance of "double spacing".
|
||
|
||
To prevent this, turn off the Exceed's "automatic font substitution"
|
||
feature (in the font part of the configuration window).
|
||
|
||
* Failure in unexec while dumping emacs on Digital Unix 4.0
|
||
|
||
This problem manifests itself as an error message
|
||
|
||
unexec: Bad address, writing data section to ...
|
||
|
||
The user suspects that this happened because his X libraries
|
||
were built for an older system version,
|
||
|
||
./configure --x-includes=/usr/include --x-libraries=/usr/shlib
|
||
|
||
made the problem go away.
|
||
|
||
* No visible display on mips-sgi-irix6.2 when compiling with GCC 2.8.1.
|
||
|
||
This problem went away after installing the latest IRIX patches
|
||
as of 8 Dec 1998.
|
||
|
||
The same problem has been reported on Irix 6.3.
|
||
|
||
* As of version 20.4, Emacs doesn't work properly if configured for
|
||
the Motif toolkit and linked against the free LessTif library. The
|
||
next Emacs release is expected to work with LessTif.
|
||
|
||
* Emacs gives the error, Couldn't find per display information.
|
||
|
||
This can result if the X server runs out of memory because Emacs uses
|
||
a large number of fonts. On systems where this happens, C-h h is
|
||
likely to cause it.
|
||
|
||
We do not know of a way to prevent the problem.
|
||
|
||
* Emacs makes HPUX 11.0 crash.
|
||
|
||
This is a bug in HPUX; HPUX patch PHKL_16260 is said to fix it.
|
||
|
||
* Emacs crashes during dumping on the HPPA machine (HPUX 10.20).
|
||
|
||
This seems to be due to a GCC bug; it is fixed in GCC 2.8.1.
|
||
|
||
* The Hyperbole package causes *Help* buffers not to be displayed in
|
||
Help mode due to setting `temp-buffer-show-hook' rather than using
|
||
`add-hook'. Using `(add-hook 'temp-buffer-show-hook
|
||
'help-mode-maybe)' after loading Hyperbole should fix this.
|
||
|
||
* Versions of the PSGML package earlier than 1.0.3 (stable) or 1.1.2

earlier versions.

|
||
|
||
--------------------------------
|
||
xmodmap 2> /dev/null - << EOF

|

--------------------------------
|
||
|
||
* Emacs hangs on KDE when a large portion of text is killed.
|
||
|
||
This is caused by a bug in the KDE applet `klipper' which periodically
|
||
requests the X clipboard contents from applications. Early versions
|
||
of klipper don't implement the ICCM protocol for large selections,
|
||
which leads to Emacs being flooded with selection requests. After a
|
||
while, Emacs will print a message:
|
||
|
||
Timed out waiting for property-notify event
|
||
|
||
A workaround is to not use `klipper'.
|
||
|
||
* Emacs compiled with DJGPP for MS-DOS/MS-Windows cannot access files
|
||
in the directory with the special name `dev' under the root of any
|
||
drive, e.g. `c:/dev'.
|
||
|
||
This is an unfortunate side-effect of the support for Unix-style
|
||
device names such as /dev/null in the DJGPP runtime library. A
|
||
work-around is to rename the problem directory to another name.
|
||
|
||
* M-SPC seems to be ignored as input.
|
||
|
||
See if your X server is set up to use this as a command
|
||
for character composition.
|
||
|
||
* Emacs startup on GNU/Linux systems (and possibly other systems) is slow.
|
||
|
||
This can happen if the system is misconfigured and Emacs can't get the
|
||
full qualified domain name, FQDN. You should have your FQDN in the
|
||
/etc/hosts file, something like this:
|
||
|
||
127.0.0.1 localhost
|
||
129.187.137.82 nuc04.t30.physik.tu-muenchen.de nuc04
|
||
|
||
The way to set this up may vary on non-GNU systems.
|
||
|
||
* Garbled display on non-X terminals when Emacs runs on Digital Unix 4.0.
|
||
|
||
So far it appears that running `tset' triggers this problem (when TERM
|
||
is vt100, at least). If you do not run `tset', then Emacs displays
|
||
properly. If someone can tell us precisely which effect of running
|
||
`tset' actually causes the problem, we may be able to implement a fix
|
||
in Emacs.
|
||
|
||
* When you run Ispell from Emacs, it reports a "misalignment" error.
|
||
|
||
This can happen if you compiled the Ispell program to use ASCII
|
||
characters only and then try to use it from Emacs with non-ASCII
|
||
characters, like Latin-1. The solution is to recompile Ispell with
|
||
support for 8-bit characters.
|
||
|
||
To see whether your Ispell program supports 8-bit characters, type
|
||
this at your shell's prompt:
|
||
|
||
ispell -vv
|
||
|
||
and look in the output for the string "NO8BIT". If Ispell says
|
||
"!NO8BIT (8BIT)", your speller supports 8-bit characters; otherwise it
|
||
does not.
|
||
|
||
To rebuild Ispell with 8-bit character support, edit the local.h file
|
||
in the Ispell distribution and make sure it does _not_ define NO8BIT.
|
||
Then rebuild the speller.
|
||
|
||
Another possible cause for "misalignment" error messages is that the
|
||
version of Ispell installed on your machine is old. Upgrade.
|
||
|
||
Yet another possibility is that you are trying to spell-check a word
|
||
in a language that doesn't fit the dictionary you choose for use by
|
||
Ispell. (Ispell can only spell-check one language at a time, because
|
||
it uses a single dictionary.) Make sure that the text you are
|
||
spelling and the dictionary used by Ispell conform to each other.
|
||
|
||
* On Linux-based GNU systems using libc versions 5.4.19 through
|
||
5.4.22, Emacs crashes at startup with a segmentation fault.
|
||
|
||
This problem happens if libc defines the symbol __malloc_initialized.
|
||
One known solution is to upgrade to a newer libc version. 5.4.33 is
|
||
known to work.
|
||
|
||
* On Windows, you cannot use the right-hand ALT key and the left-hand
|
||
CTRL key together to type a Control-Meta character.
|
||
|
||
This is a consequence of a misfeature beyond Emacs's control.
|
||
|
||
Under Windows, the AltGr key on international keyboards generates key
|
||
events with the modifiers Right-Alt and Left-Ctrl. Since Emacs cannot
|
||
distinguish AltGr from an explicit Right-Alt and Left-Ctrl
|
||
combination, whenever it sees Right-Alt and Left-Ctrl it assumes that
|
||
AltGr has been pressed.
|
||
|
||
* Under some Windows X-servers, Emacs' display is incorrect
|
||
|
||
The symptoms are that Emacs does not completely erase blank areas of the
|
||
screen during scrolling or some other screen operations (e.g., selective
|
||
display or when killing a region). M-x recenter will cause the screen
|
||
to be completely redisplayed and the "extra" characters will disappear.
|
||
|
||
This is known to occur under Exceed 6, and possibly earlier versions as
|
||
well. The problem lies in the X-server settings.
|
||
|
||
There are reports that you can solve the problem with Exceed by
|
||
running `Xconfig' from within NT, choosing "X selection", then
|
||
un-checking the boxes "auto-copy X selection" and "auto-paste to X
|
||
selection".
|
||
|
||
Of this does not work, please inform bug-gnu-emacs@gnu.org. Then
|
||
please call support for your X-server and see if you can get a fix.
|
||
If you do, please send it to bug-gnu-emacs@gnu.org so we can list it
|
||
here.
|
||
|
||
* On Solaris 2, Emacs dumps core when built with Motif.
|
||
|
||
The Solaris Motif libraries are buggy, at least up through Solaris 2.5.1.
|
||
Install the current Motif runtime library patch appropriate for your host.
|
||
(Make sure the patch is current; some older patch versions still have the bug.)
|
||
You should install the other patches recommended by Sun for your host, too.
|
||
You can obtain Sun patches from ftp://sunsolve.sun.com/pub/patches/;
|
||
look for files with names ending in `.PatchReport' to see which patches
|
||
are currently recommended for your host.
|
||
|
||
On Solaris 2.6, Emacs is said to work with Motif when Solaris patch
|
||
105284-12 is installed, but fail when 105284-15 is installed.
|
||
105284-18 might fix it again.
|
||
|
||
* On Solaris 2.6 and 7, the Compose key does not work.
|
||
|
||
This is a bug in Motif in Solaris. Supposedly it has been fixed for
|
||
the next major release of Solaris. However, if someone with Sun
|
||
support complains to Sun about the bug, they may release a patch.
|
||
If you do this, mention Sun bug #4188711.
|
||
|
||
One workaround is to use a locale that allows non-ASCII characters.
|
||
For example, before invoking emacs, set the LC_ALL environment
|
||
variable to "en_US" (American English). The directory /usr/lib/locale
|
||
lists the supported locales; any locale other than "C" or "POSIX"
|
||
should do.
|
||
|
||
pen@lysator.liu.se says (Feb 1998) that the Compose key does work
|
||
if you link with the MIT X11 libraries instead of the Solaris X11
|
||
libraries.
|
||
|
||
* Emacs does not know your host's fully-qualified domain name.
|
||
|
||
You need to configure your machine with a fully qualified domain name,
|
||
either in /etc/hosts, /etc/hostname, the NIS, or wherever your system
|
||
calls for specifying this.
|
||
|
||
If you cannot fix the configuration, you can set the Lisp variable
|
||
mail-host-address to the value you want.
|
||
|
||
* Error 12 (virtual memory exceeded) when dumping Emacs, on UnixWare 2.1
|
||
|
||
Paul Abrahams (abrahams@acm.org) reports that with the installed
|
||
virtual memory settings for UnixWare 2.1.2, an Error 12 occurs during
|
||
the "make" that builds Emacs, when running temacs to dump emacs. That
|
||
error indicates that the per-process virtual memory limit has been
|
||
exceeded. The default limit is probably 32MB. Raising the virtual
|
||
memory limit to 40MB should make it possible to finish building Emacs.
|
||
|
||
You can do this with the command `ulimit' (sh) or `limit' (csh).
|
||
But you have to be root to do it.
|
||
|
||
According to Martin Sohnius, you can also retune this in the kernel:
|

* Redisplay using X11 is much slower than previous Emacs versions.
|
||
|
||
We've noticed that certain X servers draw the text much slower when
|
||
scroll bars are on the left. We don't know why this happens. If this
|
||
happens to you, you can work around it by putting the scroll bars
|
||
on the right (as they were in Emacs 19).
|
||
|
||
Here's how to do this:
|
||
|
||
(set-scroll-bar-mode 'right)
|
||
|
||
If you're not sure whether (or how much) this problem affects you,
|
||
try that and see how much difference it makes. To set things back
|
||
to normal, do
|
||
|
||
(set-scroll-bar-mode 'left)
|
||
|
||
* Under X11, some characters appear as hollow boxes.
|
||
|
||
Each X11 font covers just a fraction of the characters that Emacs
|
||
supports. To display the whole range of Emacs characters requires
|
||
many different fonts, collected into a fontset.
|
||
|
||
If some of the fonts called for in your fontset do not exist on your X
|
||
server, then the characters that have no font appear as hollow boxes.
|
||
You can remedy the problem by installing additional fonts.
|
||
|
||
The intlfonts distribution includes a full spectrum of fonts that can
|
||
display all the characters Emacs supports.
|
||
|
||
Another cause of this for specific characters is fonts which have a
|
||
missing glyph and no default character. This is known ot occur for
|
||
character number 160 (no-break space) in some fonts, such as Lucida
|
||
but Emacs sets the display table for the unibyte and Latin-1 version
|
||
of this character to display a space.
|
||
|
||
* Under X11, some characters appear improperly aligned in their lines.
|
||
|
||
You may have bad X11 fonts; try installing the intlfonts distribution.
|
||
|
||
* Certain fonts make each line take one pixel more than it "should".
|
||
|
||
This is because these fonts contain characters a little taller
|
||
than the font's nominal height. Emacs needs to make sure that
|
||
lines do not overlap.
|
||
|
||
* You request inverse video, and the first Emacs frame is in inverse
|
||
video, but later frames are not in inverse video.
|
||
|
||
This can happen if you have an old version of the custom library in
|
||
your search path for Lisp packages. Use M-x list-load-path-shadows to
|
||
check whether this is true. If it is, delete the old custom library.
|
||
|
||
* In FreeBSD 2.1.5, useless symbolic links remain in /tmp or other
|
||
directories that have the +t bit.
|
||
|
||
This is because of a kernel bug in FreeBSD 2.1.5 (fixed in 2.2).
|
||
Emacs uses symbolic links to implement file locks. In a directory
|
||
with +t bit, the directory owner becomes the owner of the symbolic
|
||
link, so that it cannot be removed by anyone else.
|
||
|
||
If you don't like those useless links, you can let Emacs not to using
|
||
file lock by adding #undef CLASH_DETECTION to config.h.
|
||
|
||
* When using M-x dbx with the SparcWorks debugger, the `up' and `down'
|
||
commands do not move the arrow in Emacs.
|
||
|
||
You can fix this by adding the following line to `~/.dbxinit':
|
||
|
||
dbxenv output_short_file_name off
|
||
|
||
* Emacs says it has saved a file, but the file does not actually
|
||
appear on disk.
|
||
|
||
This can happen on certain systems when you are using NFS, if the
|
||
remote disk is full. It is due to a bug in NFS (or certain NFS
|
||
implementations), and there is apparently nothing Emacs can do to
|
||
detect the problem. Emacs checks the failure codes of all the system
|
||
calls involved in writing a file, including `close'; but in the case
|
||
where the problem occurs, none of those system calls fails.
|
||
|
||
* "Compose Character" key does strange things when used as a Meta key.
|
||
|
||
If you define one key to serve as both Meta and Compose Character, you
|
||
will get strange results. In previous Emacs versions, this "worked"
|
||
in that the key acted as Meta--that's because the older Emacs versions
|
||
did not try to support Compose Character. Now Emacs tries to do
|
||
character composition in the standard X way. This means that you
|
||
must pick one meaning or the other for any given key.
|
||
|
||
You can use both functions (Meta, and Compose Character) if you assign
|
||
them to two different keys.
|
||
|
||
* Emacs gets a segmentation fault at startup, on AIX4.2.
|
||
|
||
If you are using IBM's xlc compiler, compile emacs.c
|
||
without optimization; that should avoid the problem.
|
||
|
||
* movemail compiled with POP support can't connect to the POP server.
|
||
|
||
Make sure that the `pop' entry in /etc/services, or in the services
|
||
NIS map if your machine uses NIS, has the same port number as the
|
||
entry on the POP server. A common error is for the POP server to be
|
||
listening on port 110, the assigned port for the POP3 protocol, while
|
||
the client is trying to connect on port 109, the assigned port for the
|
||
old POP protocol.
|
||
|
||
* Emacs crashes in x-popup-dialog.
|
||
|
||
This can happen if the dialog widget cannot find the font it wants to
|
||
use. You can work around the problem by specifying another font with
|
||
an X resource--for example, `Emacs.dialog*.font: 9x15' (or any font that
|
||
happens to exist on your X server).
|
||
|
||
* Emacs crashes when you use Bibtex mode.
|
||
|
||
This happens if your system puts a small limit on stack size. You can
|
||
prevent the problem by using a suitable shell command (often `ulimit')
|
||
to raise the stack size limit before you run Emacs.
|
||
|
||
Patches to raise the stack size limit automatically in `main'
|
||
(src/emacs.c) on various systems would be greatly appreciated.
|
||
|
||
* Emacs crashes with SIGBUS or SIGSEGV on HPUX 9 after you delete a frame.
|
||
|
||
We think this is due to a bug in the X libraries provided by HP. With
|
||
the alternative X libraries in /usr/contrib/mitX11R5/lib, the problem
|
||
does not happen.
|
||
|
||
* Emacs crashes with SIGBUS or SIGSEGV on Solaris after you delete a frame.
|
||
|
||
We suspect that this is a similar bug in the X libraries provided by
|
||
Sun. There is a report that one of these patches fixes the bug and
|
||
makes the problem stop:

* Problems running Perl under Emacs on Windows NT/95.
|
||
|
||
`perl -de 0' just hangs when executed in an Emacs subshell.
|
||
The fault lies with Perl (indirectly with Windows NT/95).
|
||
|
||
The problem is that the Perl debugger explicitly opens a connection to
|
||
"CON", which is the DOS/NT equivalent of "/dev/tty", for interacting
|
||
with the user.
|
||
|
||
On Unix, this is okay, because Emacs (or the shell?) creates a
|
||
pseudo-tty so that /dev/tty is really the pipe Emacs is using to
|
||
communicate with the subprocess.
|
||
|
||
On NT, this fails because CON always refers to the handle for the
|
||
relevant console (approximately equivalent to a tty), and cannot be
|
||
redirected to refer to the pipe Emacs assigned to the subprocess as
|
||
stdin.
|
||
|
||
A workaround is to modify perldb.pl to use STDIN/STDOUT instead of CON.

* Problems running DOS programs on Windows NT versions earlier than 3.51.
|
||
|
||
Some DOS programs, such as pkzip/pkunzip will not work at all, while
|
||
others will only work if their stdin is redirected from a file or NUL.
|
||
|
||
When a DOS program does not work, a new process is actually created, but
|
||
hangs. It cannot be interrupted from Emacs, and might need to be killed
|
||
by an external program if Emacs is hung waiting for the process to
|
||
finish. If Emacs is not waiting for it, you should be able to kill the
|
||
instance of ntvdm that is running the hung process from Emacs, if you
|
||
can find out the process id.
|
||
|
||
It is safe to run most DOS programs using call-process (eg. M-! and
|
||
M-|) since stdin is then redirected from a file, but not with
|
||
start-process since that redirects stdin to a pipe. Also, running DOS
|
||
programs in a shell buffer prompt without redirecting stdin does not
|
||
work.
|
||
|
||
* Problems on MS-DOG if DJGPP v2.0 is used to compile Emacs:
|
||
|
||
There are two DJGPP library bugs which cause problems:
|
||
|
||
* Running `shell-command' (or `compile', or `grep') you get
|
||
`Searching for program: permission denied (EACCES), c:/command.com';
|
||
* After you shell to DOS, Ctrl-Break kills Emacs.
|
||
|
||
To work around these bugs, you can use two files in the msdos
|
||
subdirectory: `is_exec.c' and `sigaction.c'. Compile them and link
|
||
them into the Emacs executable `temacs'; then they will replace the
|
||
incorrect library functions.
|
||
|
||
* When compiling with DJGPP on Windows NT, "config msdos" fails.
|
||
|
||
If the error message is "VDM has been already loaded", this is because
|
||
Windows has a program called `redir.exe' that is incompatible with a
|
||
program by the same name supplied with DJGPP, which is used by
|
||
config.bat. To resolve this, move the DJGPP's `bin' subdirectory to
|
||
the front of your PATH environment variable.
|
||
|
||
* When compiling with DJGPP on Windows 95, Make fails for some targets
|
||
like make-docfile.
|
||
|
||
This can happen if long file name support (the setting of environment
|
||
variable LFN) when Emacs distribution was unpacked and during
|
||
compilation are not the same. See the MSDOG section of INSTALL for
|
||
the explanation of how to avoid this problem.
|
||
|
||
* Emacs compiled for MSDOS cannot find some Lisp files, or other
|
||
run-time support files, when long filename support is enabled.
|
||
|
||
Usually, this problem will manifest itself when Emacs exits
|
||
immediately after flashing the startup screen, because it cannot find
|
||
the Lisp files it needs to load at startup. Redirect Emacs stdout
|
||
and stderr to a file to see the error message printed by Emacs.
|
||
|
||
Another manifestation of this problem is that Emacs is unable to load
|
||
the support for editing program sources in languages such as C and
|
||
Lisp.
|
||
|
||
This can happen if the Emacs distribution was unzipped without LFN
|
||
support, thus causing long filenames to be truncated to the first 6
|
||
characters and a numeric tail that Windows 95 normally attaches to it.
|
||
You should unzip the files again with a utility that supports long
|
||
filenames (such as djtar from DJGPP or InfoZip's UnZip program
|
||
compiled with DJGPP v2). The MSDOG section of the file INSTALL
|
||
explains this issue in more detail.
|
||
|
||
Another possible reason for such failures is that Emacs compiled for
|
||
MSDOS is used on Windows NT, where long file names are not supported
|
||
by this version of Emacs, but the distribution was unpacked by an
|
||
unzip program that preserved the long file names instead of truncating
|
||
them to DOS 8+3 limits. To be useful on NT, the MSDOS port of Emacs
|
||
must be unzipped by a DOS utility, so that long file names are
|
||
properly truncated.
|
||
|
||
* Emacs compiled with DJGPP complains at startup:
|
||
|
||
"Wrong type of argument: internal-facep, msdos-menu-active-face"
|
||
|
||
This can happen if you define an environment variable `TERM'. Emacs
|
||
on MSDOS uses an internal terminal emulator which is disabled if the
|
||
value of `TERM' is anything but the string "internal". Emacs then
|
||
works as if its terminal were a dumb glass teletype that doesn't
|
||
support faces. To work around this, arrange for `TERM' to be
|
||
undefined when Emacs runs. The best way to do that is to add an
|
||
[emacs] section to the DJGPP.ENV file which defines an empty value for
|
||
`TERM'; this way, only Emacs gets the empty value, while the rest of
|
||
your system works as before.
|
||
|
||
* On Windows 95, Alt-f6 does not get through to Emacs.
|
||
|
||
This character seems to be trapped by the kernel in Windows 95.
|
||
You can enter M-f6 by typing ESC f6.
|
||
|
||
* Typing Alt-Shift has strange effects on Windows 95.
|
||
|
||
This combination of keys is a command to change keyboard layout. If
|
||
you proceed to type another non-modifier key before you let go of Alt
|
||
and Shift, the Alt and Shift act as modifiers in the usual way.
|
||
|
||
* `tparam' reported as a multiply-defined symbol when linking with ncurses.
|
||
|
||
This problem results from an incompatible change in ncurses, in
|
||
version 1.9.9e approximately. This version is unable to provide a
|
||
definition of tparm without also defining tparam. This is also
|
||
incompatible with Terminfo; as a result, the Emacs Terminfo support
|
||
does not work with this version of ncurses.
|
||
|
||
The fix is to install a newer version of ncurses, such as version 4.2.
|
||
|
||
* Strange results from format %d in a few cases, on a Sun.
|
||
|
||
Sun compiler version SC3.0 has been found to miscompile part of
|
||
editfns.c. The workaround is to compile with some other compiler such
|
||
as GCC.
|
||
|
||
* Output from subprocess (such as man or diff) is randomly truncated
|
||
on GNU/Linux systems.
|
||
|
||
This is due to a kernel bug which seems to be fixed in Linux version
|
||
1.3.75.
|
||
|
||
* Error messages `internal facep []' happen on GNU/Linux systems.
|
||
|
||
There is a report that replacing libc.so.5.0.9 with libc.so.5.2.16
|
||
caused this to start happening. People are not sure why, but the
|
||
problem seems unlikely to be in Emacs itself. Some suspect that it
|
||
is actually Xlib which won't work with libc.so.5.2.16.
|
||
|
||
Using the old library version is a workaround.
|
||
|
||
* On Solaris, Emacs crashes if you use (display-time).
|
||
|
||
This can happen if you configure Emacs without specifying the precise
|
||
version of Solaris that you are using.
|
||
|
||
* Emacs dumps core on startup, on Solaris.
|
||
|
||
Bill Sebok says that the cause of this is Solaris 2.4 vendor patch
|
||
102303-05, which extends the Solaris linker to deal with the Solaris
|
||
Common Desktop Environment's linking needs. You can fix the problem
|
||
by removing this patch and installing patch 102049-02 instead.
|
||
However, that linker version won't work with CDE.
|
||
|
||
Solaris 2.5 comes with a linker that has this bug. It is reported that if
|
||
you install all the latest patches (as of June 1996), the bug is fixed.
|
||
We suspect the crucial patch is one of these, but we don't know
|
||
for certain.

* Emacs dumps core if lisp-complete-symbol is called, on Solaris.
|
||
|
||
If you compile Emacs with the -fast or -xO4 option with version 3.0.2
|
||
of the Sun C compiler, Emacs dumps core when lisp-complete-symbol is
|
||
called. The problem does not happen if you compile with GCC.
|
||
|
||
* "Cannot find callback list" messages from dialog boxes on HPUX, in
|
||
Emacs built with Motif.
|
||
|
||
This problem resulted from a bug in GCC 2.4.5. Newer GCC versions
|
||
such as 2.7.0 fix the problem.
|
||
|
||
* On Irix 6.0, make tries (and fails) to build a program named unexelfsgi
|
||
|
||
A compiler bug inserts spaces into the string "unexelfsgi . o"
|
||
in src/Makefile. Edit src/Makefile, after configure is run,
|
||
find that string, and take out the spaces.
|
||
|
||
Compiler fixes in Irix 6.0.1 should eliminate this problem.
|
||
|
||
* "out of virtual swap space" on Irix 5.3
|
||
|
||
This message occurs when the system runs out of swap space due to too
|
||
many large programs running. The solution is either to provide more
|
||
swap space or to reduce the number of large programs being run. You
|
||
can check the current status of the swap space by executing the
|
||
command `swap -l'.
|
||
|
||
You can increase swap space by changing the file /etc/fstab. Adding a
|
||
line like this:
|
||
|
||
/usr/swap/swap.more swap swap pri=3 0 0
|
||
|
||
where /usr/swap/swap.more is a file previously created (for instance
|
||
by using /etc/mkfile), will increase the swap space by the size of
|
||
that file. Execute `swap -m' or reboot the machine to activate the
|
||
new swap area. See the manpages for `swap' and `fstab' for further
|
||
information.
|
||
|
||
The objectserver daemon can use up lots of memory because it can be
|
||
swamped with NIS information. It collects information about all users
|
||
on the network that can log on to the host.
|
||
|
||
If you want to disable the objectserver completely, you can execute
|
||
the command `chkconfig objectserver off' and reboot. That may disable
|
||
some of the window system functionality, such as responding CDROM
|
||
icons.
|
||
|
||
You can also remove NIS support from the objectserver. The SGI `admin'
|
||
FAQ has a detailed description on how to do that; see question 35
|
||
("Why isn't the objectserver working?"). The admin FAQ can be found at
|
||
ftp://viz.tamu.edu/pub/sgi/faq/.
|
||
|
||
* With certain fonts, when the cursor appears on a character, the
|
||
character doesn't appear--you get a solid box instead.
|
||
|
||
One user on a Linux-based GNU system reported that this problem went
|
||
away with installation of a new X server. The failing server was
|
||
XFree86 3.1.1. XFree86 3.1.2 works.
|
||
|
||
* On SunOS 4.1.3, Emacs unpredictably crashes in _yp_dobind_soft.
|
||
|
||
This happens if you configure Emacs specifying just `sparc-sun-sunos4'
|
||
on a system that is version 4.1.3. You must specify the precise
|
||
version number (or let configure figure out the configuration, which
|
||
it can do perfectly well for SunOS).
|
||
|
||
* On SunOS 4, Emacs processes keep going after you kill the X server
|
||
(or log out, if you logged in using X).
|
||
|
||
Someone reported that recompiling with GCC 2.7.0 fixed this problem.
|
||
|
||
* On AIX 4, some programs fail when run in a Shell buffer
|
||
with an error message like No terminfo entry for "unknown".
|
||
|
||
On AIX, many terminal type definitions are not installed by default.
|
||
`unknown' is one of them. Install the "Special Generic Terminal
|
||
Definitions" to make them defined.
|
||
|
||
* On SunOS, you get linker errors
|
||
ld: Undefined symbol
|
||
_get_wmShellWidgetClass
|
||
_get_applicationShellWidgetClass
|
||
|
||
The fix to this is to install patch 100573 for OpenWindows 3.0
|
||
or link libXmu statically.
|
||
|
||
* On AIX 4.1.2, linker error messages such as
|
||
ld: 0711-212 SEVERE ERROR: Symbol .__quous, found in the global symbol table
|
||
of archive /usr/lib/libIM.a, was not defined in archive member shr.o.
|
||
|
||
This is a problem in libIM.a. You can work around it by executing
|
||
these shell commands in the src subdirectory of the directory where
|
||
you build Emacs:
|
||
|
||
cp /usr/lib/libIM.a .
|
||
chmod 664 libIM.a
|
||
ranlib libIM.a
|
||
|
||
Then change -lIM to ./libIM.a in the command to link temacs (in
|
||
Makefile).
|
||
|
||
* Unpredictable segmentation faults on Solaris 2.3 and 2.4.
|
||
|
||
A user reported that this happened in 19.29 when it was compiled with
|
||
the Sun compiler, but not when he recompiled with GCC 2.7.0.
|
||
|
||
We do not know whether something in Emacs is partly to blame for this.
|
||
|
||
* Emacs exits with "X protocol error" when run with an X server for
|
||
Windows.
|
||
|
||
A certain X server for Windows had a bug which caused this.
|
||
Supposedly the newer 32-bit version of this server doesn't have the
|
||
problem.
|
||
|
||
* Emacs crashes at startup on MSDOS.
|
||
|
||
Some users report that Emacs 19.29 requires dpmi memory management,
|
||
and crashes on startup if the system does not have it. We don't yet
|
||
know why this happens--perhaps these machines don't have enough real
|
||
memory, or perhaps something is wrong in Emacs or the compiler.
|
||
However, arranging to use dpmi support is a workaround.
|
||
|
||
You can find out if you have a dpmi host by running go32 without
|
||
arguments; it will tell you if it uses dpmi memory. For more
|
||
information about dpmi memory, consult the djgpp FAQ. (djgpp
|
||
is the GNU C compiler as packaged for MSDOS.)
|
||
|
||
Compiling Emacs under MSDOS is extremely sensitive for proper memory
|
||
configuration. If you experience problems during compilation, consider
|
||
removing some or all memory resident programs (notably disk caches)
|
||
and make sure that your memory managers are properly configured. See
|
||
the djgpp faq for configuration hints.
|
||
|
||
* A position you specified in .Xdefaults is ignored, using twm.
|
||
|
||
twm normally ignores "program-specified" positions.
|
||
You can tell it to obey them with this command in your `.twmrc' file:
|
||
|
||
UsePPosition "on" #allow clients to request a position
|
||
|
||
* Compiling lib-src says there is no rule to make test-distrib.c.
|
||
|
||
This results from a bug in a VERY old version of GNU Sed. To solve
|
||
the problem, install the current version of GNU Sed, then rerun
|
||
Emacs's configure script.
|
||
|
||
* Compiling wakeup, in lib-src, says it can't make wakeup.c.
|
||
|
||
This results from a bug in GNU Sed version 2.03. To solve the
|
||
problem, install the current version of GNU Sed, then rerun Emacs's
|
||
configure script.
|
||
|
||
* On Sunos 4.1.1, there are errors compiling sysdep.c.
|
||
|
||
If you get errors such as
|
||
|
||
"sysdep.c", line 2017: undefined structure or union
|
||
"sysdep.c", line 2017: undefined structure or union
|
||
"sysdep.c", line 2019: nodename undefined
|
||
|
||
This can result from defining LD_LIBRARY_PATH. It is very tricky
|
||
to use that environment variable with Emacs. The Emacs configure
|
||
script links many test programs with the system libraries; you must
|
||
make sure that the libraries available to configure are the same
|
||
ones available when you build Emacs.
|
||
|
||
* The right Alt key works wrong on German HP keyboards (and perhaps
|
||
other non-English HP keyboards too).
|
||
|
||
This is because HPUX defines the modifiers wrong in X. Here is a
|
||
shell script to fix the problem; be sure that it is run after VUE
|
||
configures the X server.
|
||
|
||
xmodmap 2> /dev/null - << EOF
|
||
keysym Alt_L = Meta_L
|
||
keysym Alt_R = Meta_R
|
||
EOF
|
||
|
||
xmodmap - << EOF
|
||
clear mod1
|
||
keysym Mode_switch = NoSymbol
|
||
add mod1 = Meta_L
|
||
keysym Meta_R = Mode_switch
|
||
add mod2 = Mode_switch
|
||
EOF
|
||
|
||
* The Emacs window disappears when you type M-q.
|
||
|
||
Some versions of the Open Look window manager interpret M-q as a quit
|
||
command for whatever window you are typing at. If you want to use
|
||
Emacs with that window manager, you should try to configure the window
|
||
manager to use some other command. You can disable the
|
||
shortcut keys entirely by adding this line to ~/.OWdefaults:
|
||
|
||
OpenWindows.WindowMenuAccelerators: False
|
||
|
||
* Emacs does not notice when you release the mouse.
|
||
|
||
There are reports that this happened with (some) Microsoft mice and
|
||
that replacing the mouse made it stop.
|
||
|
||
* Trouble using ptys on IRIX, or running out of ptys.
|
||
|
||
The program mkpts (which may be in `/usr/adm' or `/usr/sbin') needs to
|
||
be set-UID to root, or non-root programs like Emacs will not be able
|
||
to allocate ptys reliably.
|
||
|
||
* On Irix 5.2, unexelfsgi.c can't find cmplrs/stsupport.h.
|
||
|
||
The file cmplrs/stsupport.h was included in the wrong file set in the
|
||
Irix 5.2 distribution. You can find it in the optional fileset
|
||
compiler_dev, or copy it from some other Irix 5.2 system. A kludgy
|
||
workaround is to change unexelfsgi.c to include sym.h instead of
|
||
syms.h.
|
||
|
||
* Slow startup on Linux-based GNU systems.
|
||
|
||
People using systems based on the Linux kernel sometimes report that
|
||
startup takes 10 to 15 seconds longer than `usual'.
|
||
|
||
This is because Emacs looks up the host name when it starts.
|
||
Normally, this takes negligible time; the extra delay is due to
|
||
improper system configuration. This problem can occur for both
|
||
networked and non-networked machines.
|
||
|
||
Here is how to fix the configuration. It requires being root.
|
||
|
||
** Networked Case
|
||
|
||
First, make sure the files `/etc/hosts' and `/etc/host.conf' both
|
||
exist. The first line in the `/etc/hosts' file should look like this
|
||
(replace HOSTNAME with your host name):
|
||
|
||
127.0.0.1 HOSTNAME
|
||
|
||
Also make sure that the `/etc/host.conf' files contains the following
|
||
lines:
|
||
|
||
order hosts, bind
|
||
multi on
|
||
|
||
Any changes, permanent and temporary, to the host name should be
|
||
indicated in the `/etc/hosts' file, since it acts a limited local
|
||
database of addresses and names (e.g., some SLIP connections
|
||
dynamically allocate ip addresses).
|
||
|
||
** Non-Networked Case
|
||
|
||
The solution described in the networked case applies here as well.
|
||
However, if you never intend to network your machine, you can use a
|
||
simpler solution: create an empty `/etc/host.conf' file. The command
|
||
`touch /etc/host.conf' suffices to create the file. The `/etc/hosts'
|
||
file is not necessary with this approach.
|
||
|
||
* On Solaris 2.4, Dired hangs and C-g does not work. Or Emacs hangs
|
||
forever waiting for termination of a subprocess that is a zombie.
|
||
|
||
casper@fwi.uva.nl says the problem is in X11R6. Rebuild libX11.so
|
||
after changing the file xc/config/cf/sunLib.tmpl. Change the lines
|
||
|
||
#if ThreadedX
|
||
#define SharedX11Reqs -lthread
|
||
#endif
|
||
|
||
to:
|
||
|
||
#if OSMinorVersion < 4
|
||
#if ThreadedX
|
||
#define SharedX11Reqs -lthread
|
||
#endif
|
||
#endif
|
||
|
||
Be sure also to edit x/config/cf/sun.cf so that OSMinorVersion is 4
|
||
(as it should be for Solaris 2.4). The file has three definitions for
|
||
OSMinorVersion: the first is for x86, the second for SPARC under
|
||
Solaris, and the third for SunOS 4. Make sure to update the
|
||
definition for your type of machine and system.
|
||
|
||
Then do `make Everything' in the top directory of X11R6, to rebuild
|
||
the makefiles and rebuild X. The X built this way work only on
|
||
Solaris 2.4, not on 2.3.
|
||
|
||
For multithreaded X to work it is necessary to install patch
|
||
101925-02 to fix problems in header files [2.4]. You need
|
||
to reinstall gcc or re-run just-fixinc after installing that
|
||
patch.
|
||
|
||
However, Frank Rust <frust@iti.cs.tu-bs.de> used a simpler solution:
|
||
he changed
|
||
#define ThreadedX YES
|
||
to
|
||
#define ThreadedX NO
|
||
in sun.cf and did `make World' to rebuild X11R6. Removing all
|
||
`-DXTHREAD*' flags and `-lthread' entries from lib/X11/Makefile and
|
||
typing 'make install' in that directory also seemed to work.
|
||
|
||
* With M-x enable-flow-control, you need to type C-\ twice
|
||
to do incremental search--a single C-\ gets no response.
|
||
|
||
This has been traced to communicating with your machine via kermit,
|
||
with C-\ as the kermit escape character. One solution is to use
|
||
another escape character in kermit. One user did
|
||
|
||
set escape-character 17
|
||
|
||
in his .kermrc file, to make C-q the kermit escape character.
|
||
|
||
* The Motif version of Emacs paints the screen a solid color.
|
||
|
||
This has been observed to result from the following X resource:
|
||
|
||
Emacs*default.attributeFont: -*-courier-medium-r-*-*-*-140-*-*-*-*-iso8859-*
|
||
|
||
That the resource has this effect indicates a bug in something, but we
|
||
do not yet know what. If it is an Emacs bug, we hope someone can
|
||
explain what the bug is so we can fix it. In the mean time, removing
|
||
the resource prevents the problem.
|
||
|
||
* Emacs gets hung shortly after startup, on Sunos 4.1.3.
|
||
|
||
We think this is due to a bug in Sunos. The word is that
|
||
one of these Sunos patches fixes the bug:
|
||
|
||
100075-11 100224-06 100347-03 100482-05 100557-02 100623-03 100804-03 101080-01
|

||
100170-09 100296-04 100377-09 100507-04 100567-04 100650-02 101070-01 101145-01

100178-09 100338-05 100421-03 100536-02 100584-05 100784-01 101072-01 101207-01
|
||
|
||
We don't know which of these patches really matter. If you find out
|
||
which ones, please inform bug-gnu-emacs@gnu.org.
|
||
|
||
* Emacs aborts while starting up, only when run without X.
|
||
|
||
This problem often results from compiling Emacs with GCC when GCC was
|
||
installed incorrectly. The usual error in installing GCC is to
|
||
specify --includedir=/usr/include. Installation of GCC makes
|
||
corrected copies of the system header files. GCC is supposed to use
|
||
the corrected copies in preference to the original system headers.
|
||
Specifying --includedir=/usr/include causes the original system header
|
||
files to be used. On some systems, the definition of ioctl in the
|
||
original system header files is invalid for ANSI C and causes Emacs
|
||
not to work.
|
||
|
||
The fix is to reinstall GCC, and this time do not specify --includedir
|
||
when you configure it. Then recompile Emacs. Specifying --includedir
|
||
is appropriate only in very special cases and it should *never* be the
|
||
same directory where system header files are kept.
|
||
|
||
* On Solaris 2.x, GCC complains "64 bit integer types not supported"
|
||
|
||
This suggests that GCC is not installed correctly. Most likely you
|
||
are using GCC 2.7.2.3 (or earlier) on Solaris 2.6 (or later); this
|
||
does not work without patching. To run GCC 2.7.2.3 on Solaris 2.6 or
|
||
later, you must patch fixinc.svr4 and reinstall GCC from scratch as
|
||
described in the Solaris FAQ
|
||
<http://www.wins.uva.nl/pub/solaris/solaris2.html>. A better fix is
|
||
to upgrade to GCC 2.8.1 or later.
|
||
|
||
* The Compose key on a DEC keyboard does not work as Meta key.
|
||
|
||
This shell command should fix it:
|
||
|
||
xmodmap -e 'keycode 0xb1 = Meta_L'
|
||
|
||
* Regular expressions matching bugs on SCO systems.
|
||
|
||
On SCO, there are problems in regexp matching when Emacs is compiled
|
||
with the system compiler. The compiler version is "Microsoft C
|
||
version 6", SCO 4.2.0h Dev Sys Maintenance Supplement 01/06/93; Quick
|
||
C Compiler Version 1.00.46 (Beta). The solution is to compile with
|
||
GCC.
|
||
|
||
* On Sunos 4, you get the error ld: Undefined symbol __lib_version.
|
||
|
||
This is the result of using cc or gcc with the shared library meant
|
||
for acc (the Sunpro compiler). Check your LD_LIBRARY_PATH and delete
|
||
/usr/lang/SC2.0.1 or some similar directory.
|
||
|
||
* You can't select from submenus (in the X toolkit version).
|
||
|
||
On certain systems, mouse-tracking and selection in top-level menus
|
||
works properly with the X toolkit, but neither of them works when you
|
||
bring up a submenu (such as Bookmarks or Compare or Apply Patch, in
|
||
the Files menu).
|
||
|
||
This works on most systems. There is speculation that the failure is
|
||
due to bugs in old versions of X toolkit libraries, but no one really
|
||
knows. If someone debugs this and finds the precise cause, perhaps a
|
||
workaround can be found.
|
||
|
||
* Unusable default font on SCO 3.2v4.
|
||
|
||
The Open Desktop environment comes with default X resource settings
|
||
that tell Emacs to use a variable-width font. Emacs cannot use such
|
||
fonts, so it does not work.
|
||
|
||
This is caused by the file /usr/lib/X11/app-defaults/ScoTerm, which is
|
||
the application-specific resource file for the `scoterm' terminal
|
||
emulator program. It contains several extremely general X resources
|
||
that affect other programs besides `scoterm'. In particular, these
|
||
resources affect Emacs also:
|
||
|
||
*Font: -*-helvetica-medium-r-*--12-*-p-*
|
||
*Background: scoBackground
|
||
*Foreground: scoForeground
|
||
|
||
The best solution is to create an application-specific resource file for
|
||
Emacs, /usr/lib/X11/sco/startup/Emacs, with the following contents:
|
||
|
||
Emacs*Font: -*-courier-medium-r-*-*-*-120-*-*-*-*-iso8859-1
|
||
Emacs*Background: white
|
||
Emacs*Foreground: black
|
||
|
||
(These settings mimic the Emacs defaults, but you can change them to
|
||
suit your needs.) This resource file is only read when the X server
|
||
starts up, so you should restart it by logging out of the Open Desktop
|
||
environment or by running `scologin stop; scologin start` from the shell
|
||
as root. Alternatively, you can put these settings in the
|
||
/usr/lib/X11/app-defaults/Emacs resource file and simply restart Emacs,
|
||
but then they will not affect remote invocations of Emacs that use the
|
||
Open Desktop display.
|
||
|
||
These resource files are not normally shared across a network of SCO
|
||
machines; you must create the file on each machine individually.
|
||
|
||
* rcs2log gives you the awk error message "too many fields".
|
||
|
||
This is due to an arbitrary limit in certain versions of awk.
|
||
The solution is to use gawk (GNU awk).
|
||
|
||
* Emacs is slow using X11R5 on HP/UX.
|
||
|
||
This happens if you use the MIT versions of the X libraries--it
|
||
doesn't run as fast as HP's version. People sometimes use the version
|
||
because they see the HP version doesn't have the libraries libXaw.a,
|
||
libXmu.a, libXext.a and others. HP/UX normally doesn't come with
|
||
those libraries installed. To get good performance, you need to
|
||
install them and rebuild Emacs.
|
||
|
||
* Loading fonts is very slow.
|
||
|
||
You might be getting scalable fonts instead of precomputed bitmaps.
|
||
Known scalable font directories are "Type1" and "Speedo". A font
|
||
directory contains scalable fonts if it contains the file
|
||
"fonts.scale".
|
||
|
||
If this is so, re-order your X windows font path to put the scalable
|
||
font directories last. See the documentation of `xset' for details.
|
||
|
||
With some X servers, it may be necessary to take the scalable font
|
||
directories out of your path entirely, at least for Emacs 19.26.
|
||
Changes in the future may make this unnecessary.
|
||
|
||
* On AIX 3.2.4, releasing Ctrl/Act key has no effect, if Shift is down.
|
||
|
||
Due to a feature of AIX, pressing or releasing the Ctrl/Act key is
|
||
ignored when the Shift, Alt or AltGr keys are held down. This can
|
||
lead to the keyboard being "control-locked"--ordinary letters are
|
||
treated as control characters.
|
||
|
||
You can get out of this "control-locked" state by pressing and
|
||
releasing Ctrl/Act while not pressing or holding any other keys.
|
||
|
||
* display-time causes kernel problems on ISC systems.
|
||
|
||
Under Interactive Unix versions 3.0.1 and 4.0 (and probably other
|
||
versions), display-time causes the loss of large numbers of STREVENT
|
||
cells. Eventually the kernel's supply of these cells is exhausted.
|
||
This makes emacs and the whole system run slow, and can make other
|
||
processes die, in particular pcnfsd.
|
||
|
||
Other emacs functions that communicate with remote processes may have
|
||
the same problem. Display-time seems to be far the worst.
|
||
|
||
The only known fix: Don't run display-time.
|
||
|
||
* On Solaris, C-x doesn't get through to Emacs when you use the console.
|
||
|
||
This is a Solaris feature (at least on Intel x86 cpus). Type C-r
|
||
C-r C-t, to toggle whether C-x gets through to Emacs.
|
||
|
||
* Error message `Symbol's value as variable is void: x', followed by
|
||
segmentation fault and core dump.
|
||
|
||
This has been tracked to a bug in tar! People report that tar erroneously
|
||
added a line like this at the beginning of files of Lisp code:
|
||
|
||
x FILENAME, N bytes, B tape blocks
|
||
|
||
If your tar has this problem, install GNU tar--if you can manage to
|
||
untar it :-).
|
||
|
||
* Link failure when using acc on a Sun.
|
||
|
||
To use acc, you need additional options just before the libraries, such as
|
||
|
||
/usr/lang/SC2.0.1/values-Xt.o -L/usr/lang/SC2.0.1/cg87 -L/usr/lang/SC2.0.1
|
||
|
||
and you need to add -lansi just before -lc.
|
||
|
||
The precise file names depend on the compiler version, so we
|
||
cannot easily arrange to supply them.
|
||
|
||
* Link failure on IBM AIX 1.3 ptf 0013.
|
||
|
||
There is a real duplicate definition of the function `_slibc_free' in
|
||
the library /lib/libc_s.a (just do nm on it to verify). The
|
||
workaround/fix is:
|
||
|
||
cd /lib
|
||
ar xv libc_s.a NLtmtime.o
|
||
ar dv libc_s.a NLtmtime.o
|
||
|
||
* Undefined symbols _dlopen, _dlsym and/or _dlclose on a Sun.
|
||
|
||
If you see undefined symbols _dlopen, _dlsym, or _dlclose when linking
|
||
with -lX11, compile and link against the file mit/util/misc/dlsym.c in
|
||
the MIT X11R5 distribution. Alternatively, link temacs using shared
|
||
libraries with s/sunos4shr.h. (This doesn't work if you use the X
|
||
toolkit.)
|
||
|
||
If you get the additional error that the linker could not find
|
||
lib_version.o, try extracting it from X11/usr/lib/X11/libvim.a in
|
||
X11R4, then use it in the link.
|
||
|
||
* Error messages `Wrong number of arguments: #<subr where-is-internal>, 5'
|
||
|
||
This typically results from having the powerkey library loaded.
|
||
Powerkey was designed for Emacs 19.22. It is obsolete now because
|
||
Emacs 19 now has this feature built in; and powerkey also calls
|
||
where-is-internal in an obsolete way.
|
||
|
||
So the fix is to arrange not to load powerkey.
|
||
|
||
* In Shell mode, you get a ^M at the end of every line.
|
||
|
||
This happens to people who use tcsh, because it is trying to be too
|
||
smart. It sees that the Shell uses terminal type `unknown' and turns
|
||
on the flag to output ^M at the end of each line. You can fix the
|
||
problem by adding this to your .cshrc file:
|
||
|
||
if ($?EMACS) then
|
||
if ($EMACS == "t") then
|
||
unset edit
|
||
stty -icrnl -onlcr -echo susp ^Z
|
||
endif
|
||
endif
|
||
|
||
* An error message such as `X protocol error: BadMatch (invalid
|
||
parameter attributes) on protocol request 93'.
|
||
|
||
This comes from having an invalid X resource, such as
|
||
emacs*Cursor: black
|
||
(which is invalid because it specifies a color name for something
|
||
that isn't a color.)
|
||
|
||
The fix is to correct your X resources.
|
||
|
||
* Undefined symbols when linking on Sunos 4.1 using --with-x-toolkit.
|
||
|
||
If you get the undefined symbols _atowc _wcslen, _iswprint, _iswspace,
|
||
_iswcntrl, _wcscpy, and _wcsncpy, then you need to add -lXwchar after
|
||
-lXaw in the command that links temacs.
|
||
|
||
This problem seems to arise only when the international language
|
||
extensions to X11R5 are installed.
|
||
|
||
* Typing C-c C-c in Shell mode kills your X server.
|
||
|
||
This happens with Linux kernel 1.0 thru 1.04, approximately. The workaround is
|
||
to define SIGNALS_VIA_CHARACTERS in config.h and recompile Emacs.
|
||
Newer Linux kernel versions don't have this problem.
|
||
|
||
* src/Makefile and lib-src/Makefile are truncated--most of the file missing.
|
||
|
||
This can happen if configure uses GNU sed version 2.03. That version
|
||
had a bug. GNU sed version 2.05 works properly.
|
||
|
||
* Slow startup on X11R6 with X windows.
|
||
|
||
If Emacs takes two minutes to start up on X11R6, see if your X
|
||
resources specify any Adobe fonts. That causes the type-1 font
|
||
renderer to start up, even if the font you asked for is not a type-1
|
||
font.
|
||
|
||
One way to avoid this problem is to eliminate the type-1 fonts from
|
||
your font path, like this:
|
||
|
||
xset -fp /usr/X11R6/lib/X11/fonts/Type1/
|
||
|
||
* Pull-down menus appear in the wrong place, in the toolkit version of Emacs.
|
||
|
||
An X resource of this form can cause the problem:
|
||
|
||
Emacs*geometry: 80x55+0+0
|
||
|
||
This resource is supposed to apply, and does apply, to the menus
|
||
individually as well as to Emacs frames. If that is not what you
|
||
want, rewrite the resource.
|
||
|
||
To check thoroughly for such resource specifications, use `xrdb
|
||
-query' to see what resources the X server records, and also look at
|
||
the user's ~/.Xdefaults and ~/.Xdefaults-* files.
|
||
|
||
* --with-x-toolkit version crashes when used with shared libraries.
|
||
|
||
On some systems, including Sunos 4 and DGUX 5.4.2 and perhaps others,
|
||
unexec doesn't work properly with the shared library for the X
|
||
toolkit. You might be able to work around this by using a nonshared
|
||
libXt.a library. The real fix is to upgrade the various versions of
|
||
unexec and/or ralloc. We think this has been fixed on Sunos 4
|
||
and Solaris in version 19.29.
|
||
|
||
* `make install' fails on install-doc with `Error 141'.
|
||
|
||
This happens on Ultrix 4.2 due to failure of a pipeline of tar
|
||
commands. We don't know why they fail, but the bug seems not to be in
|
||
Emacs. The workaround is to run the shell command in install-doc by
|
||
hand.
|
||
|
||
* --with-x-toolkit option configures wrong on BSD/386.
|
||
|
||
This problem is due to bugs in the shell in version 1.0 of BSD/386.
|
||
The workaround is to edit the configure file to use some other shell,
|
||
such as bash.
|
||
|
||
* Subprocesses remain, hanging but not zombies, on Sunos 5.3.
|
||
|
||
A bug in Sunos 5.3 causes Emacs subprocesses to remain after Emacs
|
||
exits. Sun patch # 101415-02 is part of the fix for this, but it only
|
||
applies to ptys, and doesn't fix the problem with subprocesses
|
||
communicating through pipes.
|
||
|
||
* Mail is lost when sent to local aliases.
|
||
|
||
Many emacs mail user agents (VM and rmail, for instance) use the
|
||
sendmail.el library. This library can arrange for mail to be
|
||
delivered by passing messages to the /usr/lib/sendmail (usually)
|
||
program . In doing so, it passes the '-t' flag to sendmail, which
|
||
means that the name of the recipient of the message is not on the
|
||
command line and, therefore, that sendmail must parse the message to
|
||
obtain the destination address.
|
||
|
||
There is a bug in the SunOS4.1.1 and SunOS4.1.3 versions of sendmail.
|
||
In short, when given the -t flag, the SunOS sendmail won't recognize
|
||
non-local (i.e. NIS) aliases. It has been reported that the Solaris
|
||
2.x versions of sendmail do not have this bug. For those using SunOS
|
||
4.1, the best fix is to install sendmail V8 or IDA sendmail (which
|
||
have other advantages over the regular sendmail as well). At the time
|
||
of this writing, these official versions are available:
|
||
|
||
Sendmail V8 on ftp.cs.berkeley.edu in /ucb/sendmail:
|
||
sendmail.8.6.9.base.tar.Z (the base system source & documentation)
|
||
sendmail.8.6.9.cf.tar.Z (configuration files)
|
||
sendmail.8.6.9.misc.tar.Z (miscellaneous support programs)
|
||
sendmail.8.6.9.xdoc.tar.Z (extended documentation, with postscript)
|
||
|
||
IDA sendmail on vixen.cso.uiuc.edu in /pub:
|
||
sendmail-5.67b+IDA-1.5.tar.gz
|
||
|
||
* On AIX, you get this message when running Emacs:
|
||
|
||
Could not load program emacs
|
||
Symbol smtcheckinit in csh is undefined
|
||
Error was: Exec format error
|
||
|
||
or this one:
|
||
|
||
Could not load program .emacs
|
||
Symbol _system_con in csh is undefined
|
||
Symbol _fp_trapsta in csh is undefined
|
||
Error was: Exec format error
|
||
|
||
These can happen when you try to run on AIX 3.2.5 a program that was
|
||
compiled with 3.2.4. The fix is to recompile.
|
||
|
||
* On AIX, you get this compiler error message:
|
||
|
||
Processing include file ./XMenuInt.h
|
||
1501-106: (S) Include file X11/Xlib.h not found.
|
||
|
||
This means your system was installed with only the X11 runtime i.d
|
||
libraries. You have to find your sipo (bootable tape) and install
|
||
X11Dev... with smit.
|
||
|
||
* You "lose characters" after typing Compose Character key.
|
||
|
||
This is because the Compose Character key is defined as the keysym
|
||
Multi_key, and Emacs (seeing that) does the proper X11
|
||
character-composition processing. If you don't want your Compose key
|
||
to do that, you can redefine it with xmodmap.
|
||
|
||
For example, here's one way to turn it into a Meta key:
|
||
|
||
xmodmap -e "keysym Multi_key = Meta_L"
|
||
|
||
If all users at your site of a particular keyboard prefer Meta to
|
||
Compose, you can make the remapping happen automatically by adding the
|
||
xmodmap command to the xdm setup script for that display.
|
||
|
||
* C-z just refreshes the screen instead of suspending Emacs.
|
||
|
||
You are probably using a shell that doesn't support job control, even
|
||
though the system itself is capable of it. Either use a different shell,
|
||
or set the variable `cannot-suspend' to a non-nil value.
|
||
|
||
* Watch out for .emacs files and EMACSLOADPATH environment vars
|
||
|
||
These control the actions of Emacs.
|
||
~/.emacs is your Emacs init file.
|
||
EMACSLOADPATH overrides which directories the function
|
||
"load" will search.
|
||
|
||
If you observe strange problems, check for these and get rid
|
||
of them, then try again.
|
||
|
||
* After running emacs once, subsequent invocations crash.
|
||
|
||
Some versions of SVR4 have a serious bug in the implementation of the
|
||
mmap () system call in the kernel; this causes emacs to run correctly
|
||
the first time, and then crash when run a second time.
|
||
|
||
Contact your vendor and ask for the mmap bug fix; in the mean time,
|
||
you may be able to work around the problem by adding a line to your
|
||
operating system description file (whose name is reported by the
|
||
configure script) that reads:
|
||
#define SYSTEM_MALLOC
|
||
This makes Emacs use memory less efficiently, but seems to work around
|
||
the kernel bug.
|
||
|
||
* Inability to send an Alt-modified key, when Emacs is communicating
|
||
directly with an X server.
|
||
|
||
If you have tried to bind an Alt-modified key as a command, and it
|
||
does not work to type the command, the first thing you should check is
|
||
whether the key is getting through to Emacs. To do this, type C-h c
|
||
followed by the Alt-modified key. C-h c should say what kind of event
|
||
it read. If it says it read an Alt-modified key, then make sure you
|
||
have made the key binding correctly.
|
||
|
||
If C-h c reports an event that doesn't have the Alt modifier, it may
|
||
be because your X server has no key for the Alt modifier. The X
|
||
server that comes from MIT does not set up the Alt modifier by
|
||
default.
|
||
|
||
If your keyboard has keys named Alt, you can enable them as follows:
|
||
|
||
xmodmap -e 'add mod2 = Alt_L'
|
||
xmodmap -e 'add mod2 = Alt_R'
|
||
|
||
If the keyboard has just one key named Alt, then only one of those
|
||
commands is needed. The modifier `mod2' is a reasonable choice if you
|
||
are using an unmodified MIT version of X. Otherwise, choose any
|
||
modifier bit not otherwise used.
|
||
|
||
If your keyboard does not have keys named Alt, you can use some other
|
||
keys. Use the keysym command in xmodmap to turn a function key (or
|
||
some other 'spare' key) into Alt_L or into Alt_R, and then use the
|
||
commands show above to make them modifier keys.
|
||
|
||
Note that if you have Alt keys but no Meta keys, Emacs translates Alt
|
||
into Meta. This is because of the great importance of Meta in Emacs.
|
||
|
||
* `Pid xxx killed due to text modification or page I/O error'
|
||
|
||
On HP/UX, you can get that error when the Emacs executable is on an NFS
|
||
file system. HP/UX responds this way if it tries to swap in a page and
|
||
does not get a response from the server within a timeout whose default
|
||
value is just ten seconds.
|
||
|
||
If this happens to you, extend the timeout period.
|
||
|
||
* `expand-file-name' fails to work on any but the machine you dumped Emacs on.
|
||
|
||
On Ultrix, if you use any of the functions which look up information
|
||
in the passwd database before dumping Emacs (say, by using
|
||
expand-file-name in site-init.el), then those functions will not work
|
||
in the dumped Emacs on any host but the one Emacs was dumped on.
|
||
|
||
The solution? Don't use expand-file-name in site-init.el, or in
|
||
anything it loads. Yuck - some solution.
|
||
|
||
I'm not sure why this happens; if you can find out exactly what is
|
||
going on, and perhaps find a fix or a workaround, please let us know.
|
||
Perhaps the YP functions cache some information, the cache is included
|
||
in the dumped Emacs, and is then inaccurate on any other host.
|
||
|
||
* On some variants of SVR4, Emacs does not work at all with X.
|
||
|
||
Try defining BROKEN_FIONREAD in your config.h file. If this solves
|
||
the problem, please send a bug report to tell us this is needed; be
|
||
sure to say exactly what type of machine and system you are using.
|
||
|
||
* Linking says that the functions insque and remque are undefined.
|
||
|
||
Change oldXMenu/Makefile by adding insque.o to the variable OBJS.
|
||
|
||
* Emacs fails to understand most Internet host names, even though
|
||
the names work properly with other programs on the same system.
|
||
* Emacs won't work with X-windows if the value of DISPLAY is HOSTNAME:0.
|
||
* GNUs can't make contact with the specified host for nntp.
|
||
|
||
This typically happens on Suns and other systems that use shared
|
||
libraries. The cause is that the site has installed a version of the
|
||
shared library which uses a name server--but has not installed a
|
||
similar version of the unshared library which Emacs uses.
|
||
|
||
The result is that most programs, using the shared library, work with
|
||
the nameserver, but Emacs does not.
|
||
|
||
The fix is to install an unshared library that corresponds to what you
|
||
installed in the shared library, and then relink Emacs.
|
||
|
||
On SunOS 4.1, simply define HAVE_RES_INIT.
|
||
|
||
If you have already installed the name resolver in the file libresolv.a,
|
||
then you need to compile Emacs to use that library. The easiest way to
|
||
do this is to add to config.h a definition of LIBS_SYSTEM, LIBS_MACHINE
|
||
or LIB_STANDARD which uses -lresolv. Watch out! If you redefine a macro
|
||
that is already in use in your configuration to supply some other libraries,
|
||
be careful not to lose the others.
|
||
|
||
Thus, you could start by adding this to config.h:
|
||
|
||
#define LIBS_SYSTEM -lresolv
|
||
|
||
Then if this gives you an error for redefining a macro, and you see that
|
||
the s- file defines LIBS_SYSTEM as -lfoo -lbar, you could change config.h
|
||
again to say this:
|
||
|
||
#define LIBS_SYSTEM -lresolv -lfoo -lbar
|
||
|
||
* On a Sun running SunOS 4.1.1, you get this error message from GNU ld:
|
||
|
||
/lib/libc.a(_Q_sub.o): Undefined symbol __Q_get_rp_rd referenced from text segment
|
||
|
||
The problem is in the Sun shared C library, not in GNU ld.
|
||
|
||
The solution is to install Patch-ID# 100267-03 from Sun.
|
||
|
||
* Self documentation messages are garbled.
|
||
|
||
This means that the file `etc/DOC-...' doesn't properly correspond
|
||
with the Emacs executable. Redumping Emacs and then installing the
|
||
corresponding pair of files should fix the problem.
|
||
|
||
* Trouble using ptys on AIX.
|
||
|
||
People often install the pty devices on AIX incorrectly.
|
||
Use `smit pty' to reinstall them properly.
|
||
|
||
* Shell mode on HP/UX gives the message, "`tty`: Ambiguous".
|
||
|
||
christos@theory.tn.cornell.edu says:
|
||
|
||
The problem is that in your .cshrc you have something that tries to
|
||
execute `tty`. If you are not running the shell on a real tty then
|
||
tty will print "not a tty". Csh expects one word in some places,
|
||
but tty is giving it back 3.
|
||
|
||
The solution is to add a pair of quotes around `tty` to make it a single
|
||
word:
|
||
|
||
if (`tty` == "/dev/console")
|
||
|
||
should be changed to:
|
||
|
||
if ("`tty`" == "/dev/console")
|
||
|
||
Even better, move things that set up terminal sections out of .cshrc
|
||
and into .login.
|
||
|
||
* Using X Windows, control-shift-leftbutton makes Emacs hang.
|
||
|
||
Use the shell command `xset bc' to make the old X Menu package work.
|
||
|
||
* Emacs running under X Windows does not handle mouse clicks.
|
||
* `emacs -geometry 80x20' finds a file named `80x20'.
|
||
|
||
One cause of such problems is having (setq term-file-prefix nil) in
|
||
your .emacs file. Another cause is a bad value of EMACSLOADPATH in
|
||
the environment.
|
||
|
||
* Emacs gets error message from linker on Sun.
|
||
|
||
If the error message says that a symbol such as `f68881_used' or
|
||
`ffpa_used' or `start_float' is undefined, this probably indicates
|
||
that you have compiled some libraries, such as the X libraries,
|
||
with a floating point option other than the default.
|
||
|
||
It's not terribly hard to make this work with small changes in
|
||
crt0.c together with linking with Fcrt1.o, Wcrt1.o or Mcrt1.o.
|
||
However, the easiest approach is to build Xlib with the default
|
||
floating point option: -fsoft.
|
||
|
||
* Emacs fails to get default settings from X Windows server.
|
||
|
||
The X library in X11R4 has a bug; it interchanges the 2nd and 3rd
|
||
arguments to XGetDefaults. Define the macro XBACKWARDS in config.h to
|
||
tell Emacs to compensate for this.
|
||
|
||
I don't believe there is any way Emacs can determine for itself
|
||
whether this problem is present on a given system.
|
||
|
||
* Keyboard input gets confused after a beep when using a DECserver
|
||
as a concentrator.
|
||
|
||
This problem seems to be a matter of configuring the DECserver to use
|
||
7 bit characters rather than 8 bit characters.
|
||
|
||
* M-x shell persistently reports "Process shell exited abnormally with code 1".
|
||
|
||
This happened on Suns as a result of what is said to be a bug in Sunos
|
||
version 4.0.x. The only fix was to reboot the machine.
|
||
|
||
* Programs running under terminal emulator do not recognize `emacs'
|
||
terminal type.
|
||
|
||
The cause of this is a shell startup file that sets the TERMCAP
|
||
environment variable. The terminal emulator uses that variable to
|
||
provide the information on the special terminal type that Emacs
|
||
emulates.
|
||
|
||
Rewrite your shell startup file so that it does not change TERMCAP
|
||
in such a case. You could use the following conditional which sets
|
||
it only if it is undefined.
|
||
|
||
if ( ! ${?TERMCAP} ) setenv TERMCAP ~/my-termcap-file
|
||
|
||
Or you could set TERMCAP only when you set TERM--which should not
|
||
happen in a non-login shell.
|
||
|
||
* X Windows doesn't work if DISPLAY uses a hostname.
|
||
|
||
People have reported kernel bugs in certain systems that cause Emacs
|
||
not to work with X Windows if DISPLAY is set using a host name. But
|
||
the problem does not occur if DISPLAY is set to `unix:0.0'. I think
|
||
the bug has to do with SIGIO or FIONREAD.
|
||
|
||
You may be able to compensate for the bug by doing (set-input-mode nil nil).
|
||
However, that has the disadvantage of turning off interrupts, so that
|
||
you are unable to quit out of a Lisp program by typing C-g.
|
||
|
||
The easy way to do this is to put
|
||
|
||
(setq x-sigio-bug t)
|
||
|
||
in your site-init.el file.
|
||
|
||
* Problem with remote X server on Suns.
|
||
|
||
On a Sun, running Emacs on one machine with the X server on another
|
||
may not work if you have used the unshared system libraries. This
|
||
is because the unshared libraries fail to use YP for host name lookup.
|
||
As a result, the host name you specify may not be recognized.
|
||
|
||
* Shell mode ignores interrupts on Apollo Domain
|
||
|
||
You may find that M-x shell prints the following message:
|
||
|
||
Warning: no access to tty; thus no job control in this shell...
|
||
|
||
This can happen if there are not enough ptys on your system.
|
||
Here is how to make more of them.
|
||
|
||
% cd /dev
|
||
% ls pty*
|
||
# shows how many pty's you have. I had 8, named pty0 to pty7)
|
||
% /etc/crpty 8
|
||
# creates eight new pty's
|
||
|
||
* Fatal signal in the command temacs -l loadup inc dump
|
||
|
||
This command is the final stage of building Emacs. It is run by the
|
||
Makefile in the src subdirectory, or by build.com on VMS.
|
||
|
||
It has been known to get fatal errors due to insufficient swapping
|
||
space available on the machine.
|
||
|
||
On 68000's, it has also happened because of bugs in the
|
||
subroutine `alloca'. Verify that `alloca' works right, even
|
||
for large blocks (many pages).
|
||
|
||
* test-distrib says that the distribution has been clobbered
|
||
* or, temacs prints "Command key out of range 0-127"
|
||
* or, temacs runs and dumps emacs, but emacs totally fails to work.
|
||
* or, temacs gets errors dumping emacs
|
||
|
||
This can be because the .elc files have been garbled. Do not be
|
||
fooled by the fact that most of a .elc file is text: these are
|
||
binary files and can contain all 256 byte values.
|
||
|
||
In particular `shar' cannot be used for transmitting GNU Emacs.
|
||
It typically truncates "lines". What appear to be "lines" in
|
||
a binary file can of course be of any length. Even once `shar'
|
||
itself is made to work correctly, `sh' discards null characters
|
||
when unpacking the shell archive.
|
||
|
||
I have also seen character \177 changed into \377. I do not know
|
||
what transfer means caused this problem. Various network
|
||
file transfer programs are suspected of clobbering the high bit.
|
||
|
||
If you have a copy of Emacs that has been damaged in its
|
||
nonprinting characters, you can fix them:
|
||
|
||
1) Record the names of all the .elc files.
|
||
2) Delete all the .elc files.
|
||
3) Recompile alloc.c with a value of PURESIZE twice as large.
|
||
(See puresize.h.) You might as well save the old alloc.o.
|
||
4) Remake emacs. It should work now.
|
||
5) Running emacs, do Meta-x byte-compile-file repeatedly
|
||
to recreate all the .elc files that used to exist.
|
||
You may need to increase the value of the variable
|
||
max-lisp-eval-depth to succeed in running the compiler interpreted
|
||
on certain .el files. 400 was sufficient as of last report.
|
||
6) Reinstall the old alloc.o (undoing changes to alloc.c if any)
|
||
and remake temacs.
|
||
7) Remake emacs. It should work now, with valid .elc files.
|
||
|
||
* temacs prints "Pure Lisp storage exhausted"
|
||
|
||
This means that the Lisp code loaded from the .elc and .el
|
||
files during temacs -l loadup inc dump took up more
|
||
space than was allocated.
|
||
|
||
This could be caused by
|
||
1) adding code to the preloaded Lisp files
|
||
2) adding more preloaded files in loadup.el
|
||
3) having a site-init.el or site-load.el which loads files.
|
||
Note that ANY site-init.el or site-load.el is nonstandard;
|
||
if you have received Emacs from some other site
|
||
and it contains a site-init.el or site-load.el file, consider
|
||
deleting that file.
|
||
4) getting the wrong .el or .elc files
|
||
(not from the directory you expected).
|
||
5) deleting some .elc files that are supposed to exist.
|
||
This would cause the source files (.el files) to be
|
||
loaded instead. They take up more room, so you lose.
|
||
6) a bug in the Emacs distribution which underestimates
|
||
the space required.
|
||
|
||
If the need for more space is legitimate, change the definition
|
||
of PURESIZE in puresize.h.
|
||
|
||
But in some of the cases listed above, this problem is a consequence
|
||
of something else that is wrong. Be sure to check and fix the real
|
||
problem.
|
||
|
||
* Changes made to .el files do not take effect.
|
||
|
||
You may have forgotten to recompile them into .elc files.
|
||
Then the old .elc files will be loaded, and your changes
|
||
will not be seen. To fix this, do M-x byte-recompile-directory
|
||
and specify the directory that contains the Lisp files.
|
||
|
||
Emacs should print a warning when loading a .elc file which is older
|
||
than the corresponding .el file.
|
||
|
||
* The dumped Emacs crashes when run, trying to write pure data.
|
||
|
||
Two causes have been seen for such problems.
|
||
|
||
1) On a system where getpagesize is not a system call, it is defined
|
||
as a macro. If the definition (in both unexec.c and malloc.c) is wrong,
|
||
it can cause problems like this. You might be able to find the correct
|
||
value in the man page for a.out (5).
|
||
|
||
2) Some systems allocate variables declared static among the
|
||
initialized variables. Emacs makes all initialized variables in most
|
||
of its files pure after dumping, but the variables declared static and
|
||
not initialized are not supposed to be pure. On these systems you
|
||
may need to add "#define static" to the m- or the s- file.
|
||
|
||
* Compilation errors on VMS.
|
||
|
||
You will get warnings when compiling on VMS because there are
|
||
variable names longer than 32 (or whatever it is) characters.
|
||
This is not an error. Ignore it.
|
||
|
||
VAX C does not support #if defined(foo). Uses of this construct
|
||
were removed, but some may have crept back in. They must be rewritten.
|
||
|
||
There is a bug in the C compiler which fails to sign extend characters
|
||
in conditional expressions. The bug is:
|
||
char c = -1, d = 1;
|
||
int i;
|
||
|
||
i = d ? c : d;
|
||
The result is i == 255; the fix is to typecast the char in the
|
||
conditional expression as an (int). Known occurrences of such
|
||
constructs in Emacs have been fixed.
|
||
|
||
* rmail gets error getting new mail
|
||
|
||
rmail gets new mail from /usr/spool/mail/$USER using a program
|
||
called `movemail'. This program interlocks with /bin/mail using
|
||
the protocol defined by /bin/mail.
|
||
|
||
There are two different protocols in general use. One of them uses
|
||
the `flock' system call. The other involves creating a lock file;
|
||
`movemail' must be able to write in /usr/spool/mail in order to do
|
||
this. You control which one is used by defining, or not defining,
|
||
the macro MAIL_USE_FLOCK in config.h or the m- or s- file it includes.
|
||
IF YOU DON'T USE THE FORM OF INTERLOCKING THAT IS NORMAL ON YOUR
|
||
SYSTEM, YOU CAN LOSE MAIL!
|
||
|
||
If your system uses the lock file protocol, and fascist restrictions
|
||
prevent ordinary users from writing the lock files in /usr/spool/mail,
|
||
you may need to make `movemail' setgid to a suitable group such as
|
||
`mail'. You can use these commands (as root):
|
||
|
||
chgrp mail movemail
|
||
chmod 2755 movemail
|
||
|
||
If your system uses the lock file protocol, and fascist restrictions
|
||
prevent ordinary users from writing the lock files in /usr/spool/mail,
|
||
you may need to make `movemail' setgid to a suitable group such as
|
||
`mail'. To do this, use the following commands (as root) after doing the
|
||
make install.
|
||
|
||
chgrp mail movemail
|
||
chmod 2755 movemail
|
||
|
||
Installation normally copies movemail from the build directory to an
|
||
installation directory which is usually under /usr/local/lib. The
|
||
installed copy of movemail is usually in the directory
|
||
/usr/local/lib/emacs/VERSION/TARGET. You must change the group and
|
||
mode of the installed copy; changing the group and mode of the build
|
||
directory copy is ineffective.
|
||
|
||
* Emacs spontaneously displays "I-search: " at the bottom of the screen.
|
||
|
||
This means that Control-S/Control-Q (XON/XOFF) "flow control" is being
|
||
used. C-s/C-q flow control is bad for Emacs editors because it takes
|
||
away C-s and C-q as user commands. Since editors do not output long
|
||
streams of text without user commands, there is no need for a
|
||
user-issuable "stop output" command in an editor; therefore, a
|
||
properly designed flow control mechanism would transmit all possible
|
||
input characters without interference. Designing such a mechanism is
|
||
easy, for a person with at least half a brain.
|
||
|
||
There are three possible reasons why flow control could be taking place:
|
||
|
||
1) Terminal has not been told to disable flow control
|
||
2) Insufficient padding for the terminal in use
|
||
3) Some sort of terminal concentrator or line switch is responsible
|
||
|
||
First of all, many terminals have a set-up mode which controls whether
|
||
they generate XON/XOFF flow control characters. This must be set to
|
||
"no XON/XOFF" in order for Emacs to work. Sometimes there is an
|
||
escape sequence that the computer can send to turn flow control off
|
||
and on. If so, perhaps the termcap `ti' string should turn flow
|
||
control off, and the `te' string should turn it on.
|
||
|
||
Once the terminal has been told "no flow control", you may find it
|
||
needs more padding. The amount of padding Emacs sends is controlled
|
||
by the termcap entry for the terminal in use, and by the output baud
|
||
rate as known by the kernel. The shell command `stty' will print
|
||
your output baud rate; `stty' with suitable arguments will set it if
|
||
it is wrong. Setting to a higher speed causes increased padding. If
|
||
the results are wrong for the correct speed, there is probably a
|
||
problem in the termcap entry. You must speak to a local Unix wizard
|
||
to fix this. Perhaps you are just using the wrong terminal type.
|
||
|
||
For terminals that lack a "no flow control" mode, sometimes just
|
||
giving lots of padding will prevent actual generation of flow control
|
||
codes. You might as well try it.
|
||
|
||
If you are really unlucky, your terminal is connected to the computer
|
||
through a concentrator which sends XON/XOFF flow control to the
|
||
computer, or it insists on sending flow control itself no matter how
|
||
much padding you give it. Unless you can figure out how to turn flow
|
||
control off on this concentrator (again, refer to your local wizard),
|
||
you are screwed! You should have the terminal or concentrator
|
||
replaced with a properly designed one. In the mean time, some drastic
|
||
measures can make Emacs semi-work.
|
||
|
||
You can make Emacs ignore C-s and C-q and let the operating system
|
||
handle them. To do this on a per-session basis, just type M-x
|
||
enable-flow-control RET. You will see a message that C-\ and C-^ are
|
||
now translated to C-s and C-q. (Use the same command M-x
|
||
enable-flow-control to turn *off* this special mode. It toggles flow
|
||
control handling.)
|
||
|
||
If C-\ and C-^ are inconvenient for you (for example, if one of them
|
||
is the escape character of your terminal concentrator), you can choose
|
||
other characters by setting the variables flow-control-c-s-replacement
|
||
and flow-control-c-q-replacement. But choose carefully, since all
|
||
other control characters are already used by emacs.
|
||
|
||
IMPORTANT: if you type C-s by accident while flow control is enabled,
|
||
Emacs output will freeze, and you will have to remember to type C-q in
|
||
order to continue.
|
||
|
||
If you work in an environment where a majority of terminals of a
|
||
certain type are flow control hobbled, you can use the function
|
||
`enable-flow-control-on' to turn on this flow control avoidance scheme
|
||
automatically. Here is an example:
|
||
|
||
(enable-flow-control-on "vt200" "vt300" "vt101" "vt131")
|
||
|
||
If this isn't quite correct (e.g. you have a mixture of flow-control hobbled
|
||
and good vt200 terminals), you can still run enable-flow-control
|
||
manually.
|
||
|
||
I have no intention of ever redesigning the Emacs command set for the
|
||
assumption that terminals use C-s/C-q flow control. XON/XOFF flow
|
||
control technique is a bad design, and terminals that need it are bad
|
||
merchandise and should not be purchased. Now that X is becoming
|
||
widespread, XON/XOFF seems to be on the way out. If you can get some
|
||
use out of GNU Emacs on inferior terminals, more power to you, but I
|
||
will not make Emacs worse for properly designed systems for the sake
|
||
of inferior systems.
|
||
|
||
* Control-S and Control-Q commands are ignored completely.
|
||
|
||
For some reason, your system is using brain-damaged C-s/C-q flow
|
||
control despite Emacs's attempts to turn it off. Perhaps your
|
||
terminal is connected to the computer through a concentrator
|
||
that wants to use flow control.
|
||
|
||
You should first try to tell the concentrator not to use flow control.
|
||
If you succeed in this, try making the terminal work without
|
||
flow control, as described in the preceding section.
|
||
|
||
If that line of approach is not successful, map some other characters
|
||
into C-s and C-q using keyboard-translate-table. The example above
|
||
shows how to do this with C-^ and C-\.
|
||
|
||
* Control-S and Control-Q commands are ignored completely on a net connection.
|
||
|
||
Some versions of rlogin (and possibly telnet) do not pass flow
|
||
control characters to the remote system to which they connect.
|
||
On such systems, emacs on the remote system cannot disable flow
|
||
control on the local system.
|
||
|
||
One way to cure this is to disable flow control on the local host
|
||
(the one running rlogin, not the one running rlogind) using the
|
||
stty command, before starting the rlogin process. On many systems,
|
||
"stty start u stop u" will do this.
|
||
|
||
Some versions of tcsh will prevent even this from working. One way
|
||
around this is to start another shell before starting rlogin, and
|
||
issue the stty command to disable flow control from that shell.
|
||
|
||
If none of these methods work, the best solution is to type
|
||
M-x enable-flow-control at the beginning of your emacs session, or
|
||
if you expect the problem to continue, add a line such as the
|
||
following to your .emacs (on the host running rlogind):
|
||
|
||
(enable-flow-control-on "vt200" "vt300" "vt101" "vt131")
|
||
|
||
See the entry about spontaneous display of I-search (above) for more
|
||
info.
|
||
|
||
* Screen is updated wrong, but only on one kind of terminal.
|
||
|
||
This could mean that the termcap entry you are using for that
|
||
terminal is wrong, or it could mean that Emacs has a bug handing
|
||
the combination of features specified for that terminal.
|
||
|
||
The first step in tracking this down is to record what characters
|
||
Emacs is sending to the terminal. Execute the Lisp expression
|
||
(open-termscript "./emacs-script") to make Emacs write all
|
||
terminal output into the file ~/emacs-script as well; then do
|
||
what makes the screen update wrong, and look at the file
|
||
and decode the characters using the manual for the terminal.
|
||
There are several possibilities:
|
||
|
||
1) The characters sent are correct, according to the terminal manual.
|
||
|
||
In this case, there is no obvious bug in Emacs, and most likely you
|
||
need more padding, or possibly the terminal manual is wrong.
|
||
|
||
2) The characters sent are incorrect, due to an obscure aspect
|
||
of the terminal behavior not described in an obvious way
|
||
by termcap.
|
||
|
||
This case is hard. It will be necessary to think of a way for
|
||
Emacs to distinguish between terminals with this kind of behavior
|
||
and other terminals that behave subtly differently but are
|
||
classified the same by termcap; or else find an algorithm for
|
||
Emacs to use that avoids the difference. Such changes must be
|
||
tested on many kinds of terminals.
|
||
|
||
3) The termcap entry is wrong.
|
||
|
||
See the file etc/TERMS for information on changes
|
||
that are known to be needed in commonly used termcap entries
|
||
for certain terminals.
|
||
|
||
4) The characters sent are incorrect, and clearly cannot be
|
||
right for any terminal with the termcap entry you were using.
|
||
|
||
This is unambiguously an Emacs bug, and can probably be fixed
|
||
in termcap.c, tparam.c, term.c, scroll.c, cm.c or dispnew.c.
|
||
|
||
* Output from Control-V is slow.
|
||
|
||
On many bit-map terminals, scrolling operations are fairly slow.
|
||
Often the termcap entry for the type of terminal in use fails
|
||
to inform Emacs of this. The two lines at the bottom of the screen
|
||
before a Control-V command are supposed to appear at the top after
|
||
the Control-V command. If Emacs thinks scrolling the lines is fast,
|
||
it will scroll them to the top of the screen.
|
||
|
||
If scrolling is slow but Emacs thinks it is fast, the usual reason is
|
||
that the termcap entry for the terminal you are using does not
|
||
specify any padding time for the `al' and `dl' strings. Emacs
|
||
concludes that these operations take only as much time as it takes to
|
||
send the commands at whatever line speed you are using. You must
|
||
fix the termcap entry to specify, for the `al' and `dl', as much
|
||
time as the operations really take.
|
||
|
||
Currently Emacs thinks in terms of serial lines which send characters
|
||
at a fixed rate, so that any operation which takes time for the
|
||
terminal to execute must also be padded. With bit-map terminals
|
||
operated across networks, often the network provides some sort of
|
||
flow control so that padding is never needed no matter how slow
|
||
an operation is. You must still specify a padding time if you want
|
||
Emacs to realize that the operation takes a long time. This will
|
||
cause padding characters to be sent unnecessarily, but they do
|
||
not really cost much. They will be transmitted while the scrolling
|
||
is happening and then discarded quickly by the terminal.
|
||
|
||
Most bit-map terminals provide commands for inserting or deleting
|
||
multiple lines at once. Define the `AL' and `DL' strings in the
|
||
termcap entry to say how to do these things, and you will have
|
||
fast output without wasted padding characters. These strings should
|
||
each contain a single %-spec saying how to send the number of lines
|
||
to be scrolled. These %-specs are like those in the termcap
|
||
`cm' string.
|
||
|
||
You should also define the `IC' and `DC' strings if your terminal
|
||
has a command to insert or delete multiple characters. These
|
||
take the number of positions to insert or delete as an argument.
|
||
|
||
A `cs' string to set the scrolling region will reduce the amount
|
||
of motion you see on the screen when part of the screen is scrolled.
|
||
|
||
* Your Delete key sends a Backspace to the terminal, using an AIXterm.
|
||
|
||
The solution is to include in your .Xdefaults the lines:
|
||
|
||
*aixterm.Translations: #override <Key>BackSpace: string(0x7f)
|
||
aixterm*ttyModes: erase ^?
|
||
|
||
This makes your Backspace key send DEL (ASCII 127).
|
||
|
||
* You type Control-H (Backspace) expecting to delete characters.
|
||
|
||
Put `stty dec' in your .login file and your problems will disappear
|
||
after a day or two.
|
||
|
||
The choice of Backspace for erasure was based on confusion, caused by
|
||
the fact that backspacing causes erasure (later, when you type another
|
||
character) on most display terminals. But it is a mistake. Deletion
|
||
of text is not the same thing as backspacing followed by failure to
|
||
overprint. I do not wish to propagate this confusion by conforming
|
||
to it.
|
||
|
||
For this reason, I believe `stty dec' is the right mode to use,
|
||
and I have designed Emacs to go with that. If there were a thousand
|
||
other control characters, I would define Control-h to delete as well;
|
||
but there are not very many other control characters, and I think
|
||
that providing the most mnemonic possible Help character is more
|
||
important than adapting to people who don't use `stty dec'.
|
||
|
||
If you are obstinate about confusing buggy overprinting with deletion,
|
||
you can redefine Backspace in your .emacs file:
|
||
(global-set-key "\b" 'delete-backward-char)
|
||
You can probably access help-command via f1.
|
||
|
||
* Editing files through RFS gives spurious "file has changed" warnings.
|
||
It is possible that a change in Emacs 18.37 gets around this problem,
|
||
but in case not, here is a description of how to fix the RFS bug that
|
||
causes it.
|
||
|
||
There was a serious pair of bugs in the handling of the fsync() system
|
||
call in the RFS server.
|
||
|
||
The first is that the fsync() call is handled as another name for the
|
||
close() system call (!!). It appears that fsync() is not used by very
|
||
many programs; Emacs version 18 does an fsync() before closing files
|
||
to make sure that the bits are on the disk.
|
||
|
||
This is fixed by the enclosed patch to the RFS server.
|
||
|
||
The second, more serious problem, is that fsync() is treated as a
|
||
non-blocking system call (i.e., it's implemented as a message that
|
||
gets sent to the remote system without waiting for a reply). Fsync is
|
||
a useful tool for building atomic file transactions. Implementing it
|
||
as a non-blocking RPC call (when the local call blocks until the sync
|
||
is done) is a bad idea; unfortunately, changing it will break the RFS
|
||
protocol. No fix was supplied for this problem.

* Vax C compiler bugs affecting Emacs.
|
||
|
||
You may get one of these problems compiling Emacs:
|
||
|
||
foo.c line nnn: compiler error: no table entry for op STASG
|
||
foo.c: fatal error in /lib/ccom
|
||
|
||
These are due to bugs in the C compiler; the code is valid C.
|
||
Unfortunately, the bugs are unpredictable: the same construct
|
||
may compile properly or trigger one of these bugs, depending
|
||
on what else is in the source file being compiled. Even changes
|
||
in header files that should not affect the file being compiled
|
||
can affect whether the bug happens. In addition, sometimes files
|
||
that compile correctly on one machine get this bug on another machine.
|
||
|
||
As a result, it is hard for me to make sure this bug will not affect
|
||
you. I have attempted to find and alter these constructs, but more
|
||
can always appear. However, I can tell you how to deal with it if it
|
||
should happen. The bug comes from having an indexed reference to an
|
||
array of Lisp_Objects, as an argument in a function call:
|
||
Lisp_Object *args;
|
||
...
|
||
... foo (5, args[i], ...)...
|
||
putting the argument into a temporary variable first, as in
|
||
Lisp_Object *args;
|
||
Lisp_Object tem;
|
||
...
|
||
tem = args[i];
|
||
... foo (r, tem, ...)...
|
||
causes the problem to go away.
|
||
The `contents' field of a Lisp vector is an array of Lisp_Objects,
|
||
so you may see the problem happening with indexed references to that.
|
||
|
||
* 68000 C compiler problems
|
||
|
||
Various 68000 compilers have different problems.
|
||
These are some that have been observed.
|
||
|
||
** Using value of assignment expression on union type loses.
|
||
This means that x = y = z; or foo (x = z); does not work
|
||
if x is of type Lisp_Object.
|
||
|
||
** "cannot reclaim" error.
|
||
|
||
This means that an expression is too complicated. You get the correct
|
||
line number in the error message. The code must be rewritten with
|
||
simpler expressions.
|
||

** XCONS, XSTRING, etc macros produce incorrect code.
|
||
|
||
If temacs fails to run at all, this may be the cause.
|
||
Compile this test program and look at the assembler code:
|
||
|
||
struct foo { char x; unsigned int y : 24; };
|
||
|
||
lose (arg)
|
||
struct foo arg;
|
||
{
|
||
test ((int *) arg.y);
|
||
}
|
||
|
||
If the code is incorrect, your compiler has this problem.
|
||
In the XCONS, etc., macros in lisp.h you must replace (a).u.val with
|
||
((a).u.val + coercedummy) where coercedummy is declared as int.
|
||
|
||
This problem will not happen if the m-...h file for your type
|
||
of machine defines NO_UNION_TYPE. That is the recommended setting now.
|
||
|
||
* C compilers lose on returning unions
|
||
|
||
I hear that some C compilers cannot handle returning a union type.
|
||
Most of the functions in GNU Emacs return type Lisp_Object, which is
|
||
defined as a union on some rare architectures.
|
||
|
||
This problem will not happen if the m-...h file for your type
|
||
of machine defines NO_UNION_TYPE.
