Cleaning up troubleshooting and other sections in FAQ; need input
20 years

After answering various faq-like questions on xemacs-beta I decided to redo
the troubleshooting section of the FAQ so it really has everything people
should know. In the process I've found some very very old stuff. Some I
just terminated with extreme prejudice [e.g. some business about OpenWindows
3.0], but others I would like to get some input before deleting them
entirely.
*********************************************************
The following used to make extensive reference to 19.14 and 19.15. I fixed
it up to remove those, but I don't know whether the resulting question has
any relevance.

＠unnumberedsubsec Q2.1.21: Movemail on Linux does not work
Movemail on Linux defaults to using ＠code{.lock} file locking. If this is
not appropriate for your system, edit src/s/linux.h and uncomment the line
that reads:
＠example
#define MAIL_USE_FLOCK

＠unnumberedsubsec Q2.0.8: can't resolve symbol _h_errno
You are using the Linux/ELF distribution of XEmacs 19.14, and your ELF
libraries are out of date. You have the following options:
＠enumerate
＠item
Upgrade your libc to at least 5.2.16 (better is 5.2.18, 5.3.12, or 5.4.10).
＠item
Patch the XEmacs binary by replacing all occurrences of ＠samp{_h_errno^＠＠}
with ＠iftex
＠*
＠end iftex
＠samp{h_errno^＠＠^＠＠}. Any version of Emacs will
suffice. If you don't understand how to do this, don't do it.
＠item
Rebuild XEmacs yourself---any working ELF version of libc should be O.K.

NB: You ＠emph{must} patch ＠file{/usr/local/bin/xemacs-19.14}, and not
＠file{xemacs} because ＠file{xemacs} is a link to ＠file{xemacs-19.14}; the

If you build against a recent libc-5.4 (late enough to have caused problems

something wrong?
Not necessarily. If you have GNU sed 3.0 you should downgrade it to 2.05.
>From the ＠file{README} at prep.ai.mit.edu:
＠quotation
sed 3.0 has been withdrawn from distribution. It has major revisions, which
mostly seem to be improvements; but it turns out to have bugs too which
cause trouble in some common cases.
Tom Lord won't be able to work fixing the bugs until May. So in the mean
time, we've decided to withdraw sed 3.0 from distribution and make version
2.05 once again the recommended version. ＠end quotation
It has also been observed that the vfork test on Solaris will leave a core
dump. ==========================================================

＠unnumberedsubsec Q2.0.11: XEmacs doesn't resolve hostnames.
This is the result of a long-standing problem with SunOS and the fact that
stock SunOS systems do not ship with DNS resolver code in libc.
＠email{ckd＠(a)loiosh.kei.com, Christopher Davis} writes:
＠quotation
That's correct [The SunOS 4.1.3 precompiled binaries don't do name lookup].
Since Sun figured that everyone used NIS to do name lookups (that DNS thing
was apparently only a passing fad, right?), the stock SunOS 4.x systems
don't have DNS-based name lookups in libc.
This is also why Netscape ships two binaries for SunOS 4.1.x.
The best solution is to compile it yourself; the configure script will check
to see if you've put DNS in the shared libc and will then proceed to link
against the DNS resolver library code. ＠end quotation

＠unnumberedsubsec Q2.1.11: Translation Table Syntax messages at Startup
I get tons of translation table syntax error messages during startup. How do
I get rid of them?
There are two causes of this problem. The first usually only strikes people
using the prebuilt binaries. The culprit in both cases is the file
＠file{XKeysymDB}.
＠itemize ＠bullet
＠item
The binary cannot find the ＠file{XKeysymDB} file. The location is hardcoded
at compile time so if the system the binary was built on puts it a different
place than your system does, you have problems. To fix, set the environment
variable ＠code{XKEYSYMDB} to the location of the ＠file{XKeysymDB} file on
your system or to the location of the one included with XEmacs which should
be at ＠iftex
＠*
＠end iftex ＠file{<xemacs_root_directory>/lib/xemacs-19.16/etc/XKeysymDB}.
＠item
The binary is finding the XKeysymDB but it is out-of-date on your system and
does not contain the necessary lines. Either ask your system administrator
to replace it with the one which comes with XEmacs (which is the stock R6
version and is backwards compatible) or set your ＠code{XKEYSYMDB} variable
to the location of XEmacs's described above. ＠end itemize

There have been several reports of the X server locking up under Linux. In

corrected the problem. This can be done with the command ＠code{xset}.
It is possible that using a font server may also solve the problem.

With XEmacs 19.13 and HP/UX 10.10, anything that relies on the

＠email{johnson＠(a)dtc.hp.com, Phil Johnson} writes:
＠quotation
This is a problem specific to HP-UX 10.10. It only occurs when XEmacs is
compiled for shared libraries (the default), so you can work around it by
compiling a statically-linked binary (run configure with
＠samp{--dynamic=no}).
I'm not sure whether the problem is with a particular shared library or if
it's a kernel problem which crept into 10.10. ＠end quotation

We don't know. It's a bug. There does seem to be a work-around, however.
Try running xclipboard first. It appears to fix the problem even if you
exit it. (This should be mostly fixed in 19.13, but we haven't yet verified
that). ==========================================================
Is the following still relevant? If so, is it relevant outside of HP/UX?

The following information comes from the ＠file{PROBLEMS} file that comes
with XEmacs.
If you're having troubles with HP/UX it is because HP/UX 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.
＠example
#! /bin/sh
xmodmap 2> /dev/null - << EOF
keysym Alt_L = Meta_L
keysym Alt_R = Meta_R

xmodmap - << EOF
clear mod1
keysym Mode_switch = NoSymbol
add mod1 = Meta_L
keysym Meta_R = Mode_switch
add mod2 = Mode_switch
EOF

How about the following question regardling TM? TM was once the way to get

＠unnumberedsubsec Q4.3.2: What is TM and where do I get it?
TM stands for ＠dfn{Tools for MIME} and not Tiny MIME. TM integrates with
all major XEmacs packages like Gnus (all flavors), VM, MH-E, and mailcrypt.
It provides totally transparent and trouble-free MIME support. When
appropriate a message will be decoded in place in an XEmacs buffer.
TM now comes as a package with XEmacs 19.16 and XEmacs 20.2.
TM was written by ＠email{morioka＠(a)jaist.ac.jp, MORIOKA Tomohiko} and
＠email{shuhei-k＠(a)jaist.ac.jp, KOBAYASHI Shuhei}.
It is based on the work of ＠email{umerin＠(a)mse.kyutech.ac.jp, UMEDA
Masanobu}, the original writer of GNUS.
The following information is from the ＠file{README}:
＠dfn{tm} is a MIME package for GNU Emacs.
tm has following functions:
＠itemize ＠bullet
＠item MIME style multilingual header.
＠item MIME message viewer (mime/viewer-mode).
＠item MIME message composer (mime/editor-mode).
＠item MIME extenders for mh-e, GNUS, RMAIL and VM.

trivial to use.

[PATCH] XEmacs 21.5-b18 (+CVS 20041130) compilation using MSVC7 Fully Win32 Native
20 years
Nelson Ferreira
Nelson Ferreira
It seems that with MSVC7 in MsXml.h there is an abort function.
Since in lisp.h a macro abort() is defined compilation fails.
Also the compiler complains a little more on some conversions.
The attached patch (mainly just some include moving and additional
casting) works for me.
