** Irix
*** 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.
*** Irix 6.5: Emacs crashes on the SGI R10K, when compiled with GCC.
This seems to be fixed in GCC 2.95.
*** Trouble using ptys on IRIX, or running out of ptys.
*** Irix: Trouble using ptys, 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.
** 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.
*** 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.

** Problems running Perl under Emacs on MS-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.

*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.

*** 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.

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.

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
