the problematic line(s) and correct them.

2004-08-21 11:31:45 +00:00
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.

2004-08-21 11:31:45 +00:00
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.

If your system uses Terminfo rather than termcap (most modern
systems do), this could happen if the proper version of
ncurses is not visible to the Emacs configure script (i.e. it
cannot be found along the usual path the linker looks for
libraries). It can happen because your version of ncurses is
obsolete, or is available only in form of binaries.

The solution is to install an up-to-date version of ncurses in
the developer's form (header files, static libraries and
symbolic links); in some GNU/Linux distributions (e.g. Debian)
it constitutes a separate package.

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
it's loaded very early in the startup procedure.)

This can happen if Emacs was built without terminfo support, but the
terminal's capabilities use format that is only supported by terminfo.
If your system has ncurses installed, this might happen if your
version of ncurses is broken; upgrading to a newer version of ncurses
and reconfiguring and rebuilding Emacs should solve this.

cygwin that becomes the cygwin supplied memalign. As malloc is not the
cygwin malloc, the cygwin memalign always returns ENOSYS. A fix for this
problem would be welcome.

in that the key acted as Meta--that's because the older Emacs versions

character composition in the standard X way. This means that you
must pick one meaning or the other for any given key.

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.

*** 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.
** NFS and RFS
*** 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.
*** 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.

** PSGML
*** Old versions of the PSGML package use the obsolete variables
`before-change-function' and `after-change-function', which are no
longer used by Emacs. Please use PSGML 1.2.3 or later.
*** PSGML conflicts with sgml-mode.
PSGML package uses the same names of some variables (like keymap)
as built-in sgml-mode.el because it was created as a replacement
of that package. The conflict will be shown if you load
sgml-mode.el before psgml.el. E.g. this could happen if you edit
HTML page and then start to work with SGML or XML file. html-mode
(from sgml-mode.el) is used for HTML file and loading of psgml.el
(for sgml-mode or xml-mode) will cause an error.
*** Versions of the PSGML package earlier than 1.0.3 (stable) or 1.1.2

** PCL-CVS
*** Lines are not updated or new lines are added in the buffer upon commit.
When committing files located higher in the hierarchy than the examined
directory, some versions of the CVS program return an ambiguous message
from which PCL-CVS cannot extract the full location of the committed
files. As a result, the corresponding lines in the PCL-CVS buffer are
not updated with the new revision of these files, and new lines are
added to the top-level directory.
This can happen with CVS versions 1.12.8 and 1.12.9. Upgrade to CVS
1.12.10 or newer to fix this problem.

2004-08-21 11:31:45 +00:00
** Miscellaneous problems
*** 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.
*** 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 ( ! ${?TERMCAP} ) setenv TERMCAP ~/my-termcap-file
Or you could set TERMCAP only when you set TERM--which should not
happen in a non-login shell.
*** In Shell mode, you get a ^M at the end of every line.
This happens to people who use tcsh, because it is trying to be too
smart. It sees that the Shell uses terminal type `unknown' and turns
on the flag to output ^M at the end of each line. You can fix the
problem by adding this to your .cshrc file:
if ($?EMACS) then
* etc/NEWS: In terminal-oriented subshells, the EMACS environment variable now defaults to Emacs's absolute file name, instead of to "t". * etc/PROBLEMS: Adjust tcsh advice for this. * make-dist (EMACS): Exit and fail if the EMACS environment variable is set to something other than an absolute file name. * lisp/comint.el (comint-exec-1): Set EMACS to the full name of Emacs, not to "t". * lisp/progmodes/compile.el (compilation-start): Likewise. * lisp/progmodes/idlwave.el (idlwave-rescan-asynchronously): Don't use expand-file-name on invocation-directory, since this might mishandle special characters in invocation-directory. * man/faq.texi (Escape sequences in shell output): EMACS is now set to Emacs's absolute file name, not to "t". (^M in the shell buffer): Likewise. * man/misc.texi (Interactive Shell): Likewise.

*** 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.
*** 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, kernel
version 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 ftp
and then choose /usr/bin/netkit-ftp.
*** JPEG images aren't displayed.
This has been reported when Emacs is built with jpeg-6a library.
Upgrading to jpeg-6b solves the problem. Configure checks for the
correct version, but this problem could occur if a binary built
against a shared libjpeg is run on a system with an older version.
*** Dired is very slow.
This could happen if invocation of the `df' program takes a long
time. Possible reasons for this include:
- ClearCase mounted filesystems (VOBs) that sometimes make `df'
response time extremely slow (dozens of seconds);
- slow automounters on some old versions of Unix;
- slow operation of some versions of `df'.
To work around the problem, you could either (a) set the variable
`directory-free-space-program' to nil, and thus prevent Emacs from
invoking `df'; (b) use `df' from the GNU Fileutils package; or
(c) use CVS, which is Free Software, instead of ClearCase.
*** Versions of the W3 package released before Emacs 21.1 don't run
under Emacs 21. This fixed in W3 version 4.0pre.47.
*** The LDAP support rely on ldapsearch program from OpenLDAP version 2.
It can fail to work with ldapsearch program from OpenLDAP version 1.
Version 1 of OpenLDAP is now deprecated. If you are still using it,
please upgrade to version 2. As a temporary workaround, remove
argument "-x" from the variable `ldap-ldapsearch-args'.
*** ps-print commands fail to find prologue files ps-prin*.ps.
This can happen if you use an old version of X-Symbol package: it
defines compatibility functions which trick ps-print into thinking it
runs in XEmacs, and look for the prologue files in a wrong directory.
The solution is to upgrade X-Symbol to a later version.
*** 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.
Similar problems could prevent Emacs from building, since the build
process invokes Emacs several times.
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.
On some systems, Emacs can crash due to problems with dynamic
linking. Specifically, on SGI Irix 6.5, crashes were reported with
backtraces like this:

(`rld' is the dynamic linker.) We don't know yet why this
happens, but setting the environment variable LD_BIND_NOW to 1 (which
forces the dynamic linker to bind all shared objects early on) seems
to work around the problem.
Please refer to the documentation of your dynamic linker for details.
*** 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.
*** 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.
If your spell-checking program is Aspell, it has been reported that if
you have a personal configuration file (normally ~/.aspell.conf), it
can cause this error. Remove that file, execute `ispell-kill-ispell'
in Emacs, and then try spell-checking again.
* Runtime problems related to font handling
** 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.

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.

By far the most frequent cause of this is a parenthesis `(' or a brace
`{' in column zero. Font Lock assumes that such a paren is outside of
any comment or string. This is of course not true in general, but the
vast majority of well-formatted program source files don't have such
parens, and therefore this assumption is used to allow optimizations
in Font Lock's syntactical analysis. These optimizations avoid some
pathological cases where jit-lock, the Just-in-Time fontification
introduced with Emacs 21.1, could significantly slow down scrolling
through the buffer, especially scrolling backwards, and also jumping
to the end of a very large buffer.

This can occur when two different versions of FontConfig are used.
For example, XFree86 4.3.0 has one version and Gnome usually comes
with a newer version. Emacs compiled with --with-gtk will then use
the newer version. In most cases the problem can be temporarily
fixed by stopping the application that has the error (it can be
Emacs or any other application), removing ~/.fonts.cache-1,
and then start the application again.
If removing ~/.fonts.cache-1 and restarting doesn't help, the
application with problem must be recompiled with the same version
of FontConfig as the rest of the system uses. For KDE, it is
sufficient to recompile Qt.

XFree86 4 contains many fonts in iso10646-1 encoding which have
minimal character repertoires (whereas the encoding part of the font
name is meant to be a reasonable indication of the repertoire
according to the XLFD spec). Emacs may choose one of these to display
characters from the mule-unicode charsets and then typically won't be
able to find the glyphs to display many characters. (Check with C-u
C-x = .) To avoid this, you may need to use a fontset which sets the
font for the mule-unicode sets explicitly. E.g. to use GNU unifont,
include in the fontset spec:

Emacs directly supports the Unicode BMP whose code points are in the
ranges 0000-33ff and e000-ffff, and indirectly supports the parts of
CJK characters belonging to these legacy charsets:
GB2312, Big5, JISX0208, JISX0212, JISX0213-1, JISX0213-2, KSC5601
The latter support is done in Utf-Translate-Cjk mode (turned on by
default). Which Unicode CJK characters are decoded into which Emacs
charset is decided by the current language environment. For instance,
in Chinese-GB, most of them are decoded into chinese-gb2312.

If you read UTF-8 data with code points outside these ranges, the
characters appear in the buffer as raw bytes of the original UTF-8
(composed into a single quasi-character) and they will be written back
correctly as UTF-8, assuming you don't break the composed sequences.
If you read such characters from UTF-16 or UTF-7 data, they are
substituted with the Unicode `replacement character', and you lose
information.

2000-12-19 17:21:55 +00:00
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'.

which is the input method for some languages. It blocks Emacs users
from using the C-SPC key for `set-mark-command'.
One solutions is to remove the `<Ctrl>space' from the `Iiimx' file
which can be found in the `/usr/lib/X11/app-defaults' directory.
However, that requires root access.
Another is to specify `Emacs*useXIM: false' in your X resources.
Another is to build Emacs with the `--without-xim' configure option.

2006-04-11 01:28:04 +00:00
The same problem happens on any other system if you are using fcitx
(Chinese input method) which by default use C-SPC for toggling. If
you want to use fcitx with Emacs, you have two choices. Toggle fcitx
by another key (e.g. C-\) by modifying ~/.fcitx/config, or be
accustomed to use C-@ for `set-mark-command'.

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.

4) Use lbxproxy on the remote end of the connection. This is an interface
to the low bandwidth X extension in most modern X servers, which
improves performance dramatically, at the slight expense of correctness
of the X protocol. lbxproxy acheives the performance gain by grouping
several X requests in one TCP packet and sending them off together,
instead of requiring a round-trip for each X request in a seperate
packet. The switches that seem to work best for emacs are:
-noatomsfile -nowinattr -cheaterrors -cheatevents
Note that the -nograbcmap option is known to cause problems.

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.

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

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

If you work in an environment where a majority of terminals of a

automatically. Here is an example:

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.

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.

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:

In this case, there is no obvious bug in Emacs, and most likely you

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.

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.

2004-08-21 11:31:45 +00:00
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.

2004-08-21 11:31:45 +00:00
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.

2004-08-21 11:31:45 +00:00
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.

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

overprint. I do not wish to propagate this confusion by conforming

For this reason, I believe `stty dec' is the right mode to use,

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'.

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'.

*** GNU/Linux: Process output is corrupted.
There is a bug in Linux kernel 2.6.10 PTYs that can cause emacs to
read corrupted process output.
*** GNU/Linux: Remote access to CVS with SSH causes file corruption.
If you access a remote CVS repository via SSH, files may be corrupted
due to bad interaction between CVS, SSH, and libc.
To fix the problem, save the following script into a file, make it
executable, and set CVS_RSH environment variable to the file name of
the script:

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:

This was reported to happen on some GNU/Linux systems which use
ncurses version 5.0, but could be relevant for other versions as well.
These versions of ncurses come with a `linux' terminfo entry, where
the "cvvis" capability (termcap "vs") is defined as "\E[?25h\E[?8c"
(show cursor, change size). This escape sequence switches on a
blinking hardware text-mode cursor whose size is a full character
cell. This blinking cannot be stopped, since a hardware cursor
always blinks.

2004-08-21 11:31:45 +00:00
A work-around is to redefine the "cvvis" capability so that it
enables a *software* cursor. The software cursor works by inverting
the colors of the character at point, so what you see is a block
cursor that doesn't blink. For this to work, you need to redefine
the "cnorm" capability as well, so that it operates on the software
cursor instead of the hardware cursor.

To this end, run "infocmp linux > linux-term", edit the file

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

On a Sun, running Emacs on one machine with the X server on another

is because the unshared libraries fail to use YP for host name lookup.

characters, ISO 8859-8 for Hebrew characters, etc.). To make these
input methods work with Emacs, 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 this:
C-x RET k hebrew-iso-8bit 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.) In addition, to use these Windows input methods, you
should set your "Language for non-Unicode programs" (on Windows XP,
this is on the Advanced tab of Regional Settings) to the language of
the input method.

(MS-Windows problems): How to bind non-ASCII keys with modifiers.
2007-03-31 10:01:51 +00:00
To bind keys that produce non-ASCII characters with modifiers, you
must specify raw byte codes. For instance, if you want to bind
META-a-grave to a command, you need to specify this in your `~/.emacs':
(global-set-key [?\M-\340] ...)
The above example is for the Latin-1 environment where the byte code
of the encoded a-grave is 340 octal. For other environments, use the
encoding appropriate to that environment.

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. A
more permanent work around is to change it to another key combination,
or disable it in the keyboard control panel.

Document problems with rebasing Cygwin DLLs.
2006-12-16 14:00:15 +00:00
** Cygwin build of Emacs hangs after rebasing Cygwin DLLs
Usually, on Cygwin, one needs to rebase the DLLs if an application
aborts with a message like this:
C:\cygwin\bin\python.exe: *** unable to remap C:\cygwin\bin\cygssl.dll to
same address as parent(0xDF0000) != 0xE00000
However, since Cygwin DLL 1.5.17 was released, after such rebasing,
Emacs hangs.
This was reported to happen for Emacs 21.2 and also for the pretest of
Emacs 22.1 on Cygwin.
To work around this, build Emacs like this:
LDFLAGS='-Wl,--enable-auto-import -Wl,--enable-auto-image-base' ./configure
make LD='$(CC)'
make LD='$(CC)' install
This produces an Emacs binary that is independent of rebasing.
Note that you _must_ use LD='$(CC)' in the last two commands above, to
prevent GCC from passing the "--image-base 0x20000000" option to the
linker, which is what it does by default. That option produces an
Emacs binary with the base address 0x20000000, which will cause Emacs
to hang after Cygwin DLLs are rebased.

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.)

If the FTP client is the Cygwin port of GNU `ftp', this appears to be
due to some bug in the Cygwin DLL or some incompatibility between it
and the implementation of asynchronous subprocesses in the Windows
port of Emacs. Specifically, some parts of the FTP server responses
are not flushed out, apparently due to buffering issues, which
confuses ange-ftp.

The solution is to downgrade to an older version of the Cygwin DLL
(version 1.3.2 was reported to solve the problem), or use the stock
Windows FTP client, usually found in the `C:\WINDOWS' or 'C:\WINNT'
directory. To force ange-ftp use the stock Windows client, set the
variable `ange-ftp-ftp-program-name' to the absolute file name of the
client's executable. For example:

AltGr has been pressed. The variable `w32-recognize-altgr' can be set

There are reports that this happens on some systems because the linker
by default only looks for shared libraries, but jpeg distribution by
default only installs a nonshared version of the library, `libjpeg.a'.

If this is the problem, 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, and edit src/config.h to define HAVE_JPEG.

(Configuration): Add entries on compiler/preprocessor mismatch, and on preprocessor inserting whitespace.
2007-04-04 02:58:38 +00:00
*** `configure' warns ``accepted by the compiler, rejected by the preprocessor''.
This indicates a mismatch between the C compiler and preprocessor that
configure is using. For example, on Solaris 10 trying to use
CC=/opt/SUNWspro/bin/cc (the Sun Studio compiler) together with
CPP=/usr/ccs/lib/cpp can result in errors of this form (you may also
see the error ``"/usr/include/sys/isa_defs.h", line 500: undefined control'').
The solution is to tell configure to use the correct C preprocessor
for your C compiler (CPP="/opt/SUNWspro/bin/cc -E" in the above
example).
*** `configure' fails with ``"junk.c", line 660: invalid input token: 8.elc''
The final stage of the Emacs configure process uses the C preprocessor
to generate the Makefiles. Errors of this form can occur if the C
preprocessor inserts extra whitespace into its output. The solution
is to find the switches that stop your preprocessor from inserting extra
whitespace, add them to CPPFLAGS, and re-run configure. For example,
this error can occur on Solaris 10 when using the Sun Studio compiler
``Sun C 5.8'' with its preprocessor CPP="/opt/SUNWspro/bin/cc -E".
The relevant switch in this case is "-Xs" (``compile assuming
(pre-ANSI) K & R C style code'').

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 executable 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

waiting for 10 or more seconds between the two Make invocations seemed
to work around the problem.

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; similar problems were reported with some snapshots of GCC 3.1
around Sep 30 2001. The preprocessor in those versions is
incompatible with a traditional Unix cpp (e.g., it expands ".." into
". .", which breaks relative file names that reference the parent
directory; or inserts TAB characters before lines that set Make
variables).

The solution is to make sure the preprocessor is run with the

when it detects the known problems in your cpp, but you might hit some
unknown ones. To force the `configure' script to use `-traditional',
run the script like this:

This problem results from an incompatible change in ncurses, in

definition of tparm without also defining tparam. This is also
incompatible with Terminfo; as a result, the Emacs Terminfo support

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.

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.

This was reported to happen when Emacs is built in a directory mounted
via NFS, for some combinations of NFS client and NFS server.
Usually, the file `emacs' produced in these cases is full of
binary null characters, and the `file' utility says:

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.

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

AIX 4.2 was end-of-lifed on Dec 31st, 1999.
*** 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.
(This report must be ancient. Bootable tapes are long dead.)
*** 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.
*** AIX 3.2.5: 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.
*** AIX 4.2: Emacs gets a segmentation fault at startup.
If you are using IBM's xlc compiler, compile emacs.c
without optimization; that should avoid the problem.

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.

**** SunOS4.1.1 and SunOS4.1.3: Mail is lost when sent to local aliases.
#
1999-10-03 12:39:42 +00:00
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)

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:

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.

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 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.

are currently recommended for your host.

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.

HP/UX 10 was end-of-lifed in May 1999.
**** HP/UX 9: Emacs crashes with SIGBUS or SIGSEGV 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.
*** HP/UX 10: Large file support is disabled.
See the comments in src/s/hpux10.h.
*** HP/UX: Emacs is slow using X11R5.
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.

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.

shipped in 1994, it has been some years.
**** 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.
**** Irix 5.3: "out of virtual swap space".
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/.
**** Irix 5.3: Emacs crashes in utmpname.
This problem is fixed in Patch 3175 for Irix 5.3.
It is also fixed in Irix versions 6.2 and up.
**** 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.
*** SCO Unix and UnixWare
**** SCO 3.2v4: Unusable default font.
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.
**** SCO 4.2.0: 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.
**** UnixWare 2.1: Error 12 (virtual memory exceeded) when dumping Emacs.
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:
# /etc/conf/bin/idtune SDATLIM 33554432 ## soft data size limit
# /etc/conf/bin/idtune HDATLIM 33554432 ## hard "
# /etc/conf/bin/idtune SVMMSIZE unlimited ## soft process size limit
# /etc/conf/bin/idtune HVMMSIZE unlimited ## hard "
# /etc/conf/bin/idbuild -B
(He recommends you not change the stack limit, though.)
These changes take effect when you reboot.

** Windows 3.1, 95, 98, and ME
*** MS-Windows NT/95: Problems running Perl under Emacs
`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.

*** MS-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.
*** MS-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
http://www.gnu.org/software/emacs/windows/.
*** MS-Windows 95/98/ME: crashes when Emacs invokes non-existent programs.
When a program you are trying to run is not found on the PATH,
Windows might respond by crashing or locking up your system. In
particular, this has been reported when trying to compile a Java
program in JDEE when javac.exe is installed, but not on the system
PATH.

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.

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

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.

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

** Vax C compiler bugs affecting Emacs.
#
1999-10-03 12:39:42 +00:00
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.

*** 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.
