* Emacs 19 problems
** 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 It is obsolete now because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.
* Runtime problems on legacy systems
This section covers bugs reported on very old hardware or software.
If you are using hardware and an operating system shipped after 2000,
it is unlikely you will see any of these.
** Ancient operating systems
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.
*** ISC Unix
**** ISC: 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.
**** Sunos 5.3: Subprocesses remain, hanging but not zombies.
*** Sunos 5.3: Subprocesses remain, hanging but not zombies.
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.
*** Irix

This problem went away after installing the latest IRIX patches

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.
**** Solaris 2.4: Emacs dumps core on startup.
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.

with patches 102980-04, 103279-01, 103300-02, and 103468-01.)
If you can determine which patch does fix the bug, please tell
bug-gnu-emacs@gnu.org.
Meanwhile, the GNU linker links Emacs properly on both Solaris 2.4 and
Solaris 2.5.
**** 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.

On Ultrix, if you use any of the functions which look up information

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.

in the dumped Emacs, and is then inaccurate on any other host.

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.
