Most external libraries used by XEmacs can be found at the XEmacs FTP site: http://ftp.xemacs.org/pub/xemacs/aux/.
This page lists programs that are not included in the XEmacs distribution, but which are either used by various packages that are in the distribution or are enhancements which can be compiled into XEmacs. Where available, ftp sites, web home pages, and configure flags (although you should never have to specify library configure flags since they are autodetected) are indicated below.
Most of the files listed below contain the sources to these programs, and you will have to build them yourself. However, some binaries are available for the Win32 (i.e. native Windows 9x/NT/2000/XP), Cygwin and MinGW platforms.
The win32 directory contains binaries for common graphics libraries needed for building XEmacs and for zlib, needed to support the PNG library. We recommend that you run optional-libs.exe, a self-extracting executable, which will install pre-built binaries for all of the optional graphics libraries needed by XEmacs, in the correct hierarchy as expected by XEmacs. Then just set the OPTIONAL_LIBRARY_DIR parameter to the appropriate directory in which you installed the libraries (by default, c:\src).
We no longer provide binaries for CVS, SSH or patch. If you want these, just install Cygwin, which provides versions of these and all other common Unix utilities, has an easy install program, and is frequently updated.
Cygwin is a POSIX emulation environment for MS Windows. Development on Cygwin is quite active. Nearly every major or even semi-significant open-source Unix package on earth has been ported to Cygwin and is available in pre-built format from the Cygwin website. If you are planning on doing any development on XEmacs under Windows it's pretty much mandatory to install Cygwin. Among other things, you will undoubtedly need ssh and CVS, and GNU make as well if you want to rebuild the XEmacs packages or the web site.
Get Cygwin from http://www.cygwin.com/ . (You will be asked to choose a mirror site; try mirrors.rcn.net.) Part of the setup process allows you to install XFree86. Other useful packages to consider are CVS (for access to the XEmacs source tree), ssh (needed in conjunction with CVS), make (for building the packages or the web site), gcc (for compiling XEmacs under Cygwin), png/zlib/Xpm/jpeg/tiff/compface libraries (see below), various other libraries (see below; prebuilt versions of most of them exist), autoconf (for rebuilding configure), TeX (for rebuilding certain parts of the package hierarchy), and wget (for rebuilding the web site).
Get MinGW from http://www.mingw.org/. (MinGW is a version of GCC that uses native Microsoft DLL's instead of requiring a POSIX-emulation DLL, as Cygwin does.)
The mingw directory contains binaries for the graphics libraries (Xpm, png+zlib, jpeg, tiff, compface -- remember that gif support is built in) needed for building XEmacs using the MinGW compiler. NOTE: Many of the binaries are out-of-date. Compile them yourself if possible.
The ZLIB compression library (strongly
encouraged when building XEmacs) is used by the PNG library.
A GZIP coding system is also available, in XEmacs 21.5 and onward.
compface (not especially important when building XEmacs)
is an old library for viewing X-Faces in messages.
It is not really being maintained, but still works.
The version of this library at xemacs.org
includes the xbm2xface.pl script, written by email@example.com,
which may be useful when generating your own xface.
OpenMotif is the free release of Motif, a standard widget
set for X Windows.
LessTif is a library that is compatible with Motif, dating back from the days before Motif was free and still actively developed.
These DBM implementations are supported by XEmacs: native dbm (provided by OS), GDBM, and Berkeley DB version 1, 2 and 3.
Wnn is a multi-language mule input method. Wnn6 and
Wnn7 are commercial versions. Wnn4, now completely orphaned, was once
the free version. There is now a FreeWnn effort; it is not verified
whether this version works with XEmacs.
The Wnn sites are in Japanese. Here is a site in English with some
info on WNN:
mlterm is a multi-lingual terminal emulator with
special support for Asian languages with large character sets.
There are other similar programs (e.g. xiterm), but this one appears
to be the most actively maintained.
kterm was for a long time the standard Asian-language
terminal emulator, but appears to have not been maintained since 1996.
ispell is a spelling checker with support for multiple languages.
SKK (Simple Kana-to-Kanji) is a simple input method for Japanese.
It has been modified to work with XEmacs.
X11 fonts for numerous languages.
CVS is the version control system used by XEmacs to manage the sources.
Use autoconf to generate `configure' from `configure.in'.
Use the applypatch program from the makepatch package
to apply patches to upgrade from one beta release to another.
Use this if you have a slow or expensive connection to the Net.
