* Problems with building XEmacs
===============================
** General
+ Much general information is in INSTALL. If it's covered in
+ INSTALL, we don't repeat it here.
+
+*** How does I configure to get the buffer tabs/progress bars?
+
+These features depend on support for "native widgets". Use the
+--with-widgets option to configure. Configuration of widgets is
+automatic for "modern" toolkits (MS Windows, GTK, and Motif), but if
+you are using Xt and the Athena widgets, you will probably want to
+specify a "3d" widget set. See configure --usage, and don't forget to
+install the corresponding development libraries.
+
+*** I know I have libfoo installed, but configure doesn't find it.
+
+Typical of Linux systems with package managers. To link with a shared
+library, you only need the shared library. To compile objects that
+link with it, you need the headers---and distros don't provide them with
+the libraries. You need the additional "development" package, too.
+
*** Don't use -O2 with gcc 2.8.1 and egcs 1.0 under SPARC architectures
without also using `-fno-schedule-insns'.
** SunOS/Solaris
+*** Crashes when using Motif libraries, especially with multiple frames.
+
+Crashes that produce C-backtraces like this:

+
+Your partition holding the source files is mounted binary. It needs

* Problems with running XEmacs
==============================
** General
+*** At startup I get a warning on stderr about missing charsets:
+
+ Warning: Missing charsets in String to FontSet conversion
+
+You need to specify appropriate charsets for your locale (usually the
+value of the LANG environment variable) in .Xresources. See
+etc/Emacs.ad for the relevant resources (mostly menubar fonts and
+fontsets). Do not edit this file, it's purely informative.
+
+If you have no satisfactory fonts for iso-8859-1, XEmacs will crash.
+
+It looks like XFree86 4.x (the usual server on Linux and *BSD) has
+some braindamage where .UTF-8 locales will always generate this
+message, because the XFree86 (font)server doesn't know that UTF-8 will
+use the ISO10646-1 font registry (or a Cmap or something).
+
+If you are not using a .UTF-8 locale and see this warning for a
+character set not listed in the default in Emacs.ad, please let
+xemacs-beta@xemacs.org know about it, so we can add fonts to the
+appropriate fontsets and stifle this warning. (Unfortunately it's
+buried in Xlib, so we can't easily get rid of it otherwise.)
+
+*** Whenever I try to retrieve a remote file, I have problems.
+
+A typical error: FTP Error: USER request failed; 500 AUTH not understood.
+Thanks to giacomo boffi <giacomo.boffi@polimi.it> on comp.emacs.xemacs:
+
+ tell your ftp client to not attempt AUTH authentication (or do not
+ use FTP servers that don't understand AUTH)

+** MacOS/X, Darwin
+*** XEmacs crashes on MacOS within font-lock, or when dealing
+with large compilation buffers, or in other regex applications.
+
+The default stack size under MacOS/X is rather small (512k as opposed
+to Solaris 8M), hosing the regexp code, which uses alloca()
+extensively, overflowing the stack when complex regexps are used.
+Workarounds:
+
+1) Increase your stack size, using `ulimit -s 8192' or a (t)csh
+ equivalent;
+
+2) Recompile regex.c with REGEX_MALLOC defined.
+
** AIX
*** Your Delete key sends a Backspace to the terminal, using an AIXterm.
** Linux
+*** XEmacs crashes on startup, in make-frame.
+
+Typically the Lisp backtrace includes
+
+ make-frame(nil #<x-device on ":0.0" 0x2558>)
+
+somewhere near the top. One problem is due to an improvement in GNU
+ld that sorts the ELF reloc sections in the executable, giving
+dramatic speedups in startup for large executables. It also confuses
+the traditional unexec code in XEmacs, leading to the core dump. The
+solution is to use either the `--ldflags="-z nocombreloc" or the
+"--pdump" option to configure. "--pdump" is recommended.
+
+Recent 21.4 and 21.5 versions of XEmacs autodetect this feature of ld
+in configure. Unfortunately, Red Hat and SuSE (at least) distributed
+prerelease versions of ld (numbered around 2.11.90.x.y, nicknamed
+"Hannibal Lecter" at XEmacs.ORG) where autodetection fails but the
+feature is enabled by default. The recommended procedure is to
+upgrade to binutils >= 2.12 and rerun configure. Otherwise you must
+apply the flags by hand.
+
+Andrew Jaffe reported a problem on Red Hat 7.3 with identical
+symptoms, except that ld was already being invoked with -z
+nocombreloc. Switching dialogs and widgets from Motif to Athena
+eliminated the problem. Both LessTif and OpenMotif were installed,
+and a bad interaction is suspected. This problem has not yet been
+fully analyzed.
+
+*** Debian
+**** XEmacs warns "Symbol `toggleClassRec' has different size in shared
+ object, consider re-linking / Symbol `labelClassRec' has different
+ size in shared object, consider re-linking / Warning: Representation
+ size 4 must match superclass's to override value"
+
+Sometimes this results in segfaults when using the tab control widget
+or a progress bar widget.
+
+Some versions of Debian install 3D versions of the Athena widget
+library as /usr/X11R6/lib/libXaw.so. We have not yet solved the
+problem of identifying the actual library in use in ./configure, so it
+is possible for XEmacs to be compiled with reference to headers for
+"flat" Xaw but find a "3D" Xaw when loading.
+
+The straightforward solution is to rebuild XEmacs with additional
+configure options: --with-widgets=athena --with-athena=3d.
+
+There are several 3D Athena widget sets available; to see which ones
+are supported by XEmacs, use ./configure --usage.
+
*** Mandrake
The Mandrake Linux distribution is attempting to comprehensively
The color-gcc wrapper (see below) is in common use on the Mandrake
platform.
+*** XEmacs configured with ESD crashes with a segmentation violation
+
+This often occurs when a progress bar pops up.
+
+The problem is that the ESD sound daemon manipulates interrupts in a
+way that disagrees with XEmacs. The currently available workaround is
+not very satisfactory: remove ESD support. Rebuild after
+reconfiguring with the option --with-sound=none[,native][,nas]
+
+The funny syntax (requiring the initial "none") is for backward
+compatibility, and may change. Native sound and NAS do not cause the
+problem, so they may be added to the option to get some sound support.
+
*** I want XEmacs to use the Alt key, not the XXX key, for Meta commands
For historical reasons, XEmacs looks for a Meta key, then an Alt key.
This is written for the mainline GNU Emacs but the author has made
efforts to adapt it to XEmacs. YMMV.
