You are running an experimental version of XEmacs. Please do not
report problems with Beta XEmacs to comp.emacs.xemacs. Report them to
** XEmacs Beta Mailing List
If you are not subscribed to the XEmacs beta list you should be. Send
an email message to email@example.com with `subscribe'
(without the quotes) as the BODY of the message.
To unsubscribe from the list send an email message to
firstname.lastname@example.org with `unsubscribe' (without the quotes)
as the BODY of the message.
The XEmacs beta list is managed by the Majordomo mailing list package,
and the usual Majordomo commands work. Do not send mailing list
requests to the main address (email@example.com), always send
them to firstname.lastname@example.org. If you have problems with the
list itself, they should be brought to the attention of the XEmacs
Mailing List manager Jason Mastaler <email@example.com>.
** Beta Release Schedule
The URL ftp://ftp.xemacs.org/pub/xemacs/beta/README always contains
the best estimate of when the next beta XEmacs will be released. For
weekend betas the release time is generally in the vicinity of 2PM to
5PM US Pacific Time (Universal Time minus 8 hours). For weekday
betas, the release time is generally in the vicinity of 8PM to
Midnight US Pacific Time on the listed day.
Betas are nominally a week apart, scheduled on every Saturday.
Midweek releases are made when a serious enough problem warrants it.
** Reporting Problems
The best way to get problems fixed in XEmacs is to submit good problem
reports. Since this is beta software, problems are certain to exist.
Please read through all of part II of the XEmacs FAQ for an overview
of problem reporting. Other items which are most important are:
1. Do not submit C stack backtraces without line numbers. Since it
is possible to compile optimized with debug information with GCC
it is never a good idea to compile XEmacs without the -g flag.
XEmacs runs on a variety of platforms, and often it is not
possible to recreate problems which afflict a specific platform.
The line numbers in the C stack backtrace help isolate where the
problem is actually occurring.
2. Attempt to recreate the problem starting with an invocation of
XEmacs with `xemacs -q -no-site-file'. Quite often, problems are
due to package interdependencies, and the like. An actual bug in
XEmacs should be reproducible in a default configuration without
loading any special packages (or the one or two specific packages
that cause the bug to appear).
3. A picture can be worth a thousand words. When reporting an
unusual display, it is generally best to capture the problem in a
screen dump and include that with the problem report. The easiest
way to get a screen dump is to use the xv program and its grab
function. Save the image as a GIF to keep bandwidth requirements
down without loss of information. MIME is the preferred method
for making the image attachments.
** Getting the Source
In addition to the normal tar distribution, XEmacs source is now
available via CVS. Please see the URL: <URL:http://cvs.xemacs.org/~xemacs/>.
* Compiling Beta XEmacs
** Building an XEmacs from patches
All beta releases of XEmacs are included with patches from the
previous version in an attempt to keep bandwidth requirements down.
Patches should be applied with the GNU patch program in something like
the following. Let's say you're upgrading XEmacs 20.15-beta10 to
XEmacs 20.15-beta11 and you have a full unmodified XEmacs 20.15-beta10
source tree to work with. Cd to the top level directory and issue the
$ gunzip -c /tmp/xemacs-20.15-b10-20.15-b11.patch.gz | patch -p1
After patching, check to see that no patches were missed by doing
$ find . -name \*.rej -print
Any rejections should be treated as serious problems to be resolved
before building XEmacs.
After seeing that there were no rejections, issue the commands
$ ./config.status --recheck
$ make beta
and go play minesweep for a while on an older XEmacs while the binary
** Building XEmacs from a full distribution
Locate a convenient place where you have at least 100MB of free space
and issue the command
$ gunzip -c /tmp/xemacs-20.15-b11.tar.gz | tar xvf -
(or simply `tar zxvf /tmp/xemacs-20.15-b11.tar.gz' if you use GNU tar).
cd to the top level directory and issue an appropriate configure
command. One maintainer uses the following at the time of this
--cflags="-mpentium -march=pentium -O6 -g -fno-peep-spills" \
--error-checking=all --debug=yes \
--with-scrollbars=athena3d --with-dialogs=athena3d \
--with-mule --with-xfs --with-xim=xlib
Part of the configure output is a summary that looks something like:
uname -a: Linux altair.xemacs.org 2.0.32 #2 Sun Nov 16 18:52:14 PST 1997 i586
./configure '--cflags=-mpentium -march=pentium -O6 -g -fno-peep-spills' '--error-checking=all' '--debug=yes' '--with-scrollbars=athena3d' '--with-dialogs=athena3d' '--with-mule' '--with-xfs' '--with-xim=xlib'

Then type `make' and you should have a working XEmacs.
After you have verified that you have a functional editor, fire up
your favorite mail program and send a build report to
firstname.lastname@example.org. The build report should include
1. Your hardware configuration (OS version, etc.)
2. Version numbers of software in use (X11 version, system library
versions if appropriate, graphics library versions if appropriate).
If you're on a system like Linux, include all the version numbers
you can because chances are it makes a difference.
3. The options given to configure
4. The configuration report illustrated above
For convenience all of the above items are placed in a file called
`Installation' in the top level build directory. They are also
available by performing M-x describe-installation inside XEmacs.
5. Any other unusual items you feel should be brought to the attention
of the developers.
** Creating patches for submission
When making patches please use the `-u' option, or if your diff
doesn't support it, `-c'. Using ordinary (context-free) diffs are
notoriously prone to error, since line numbers tend to change when
others make changes to the same source file.
$ diff -u old-file.c new-file.c
$ diff -c old-file.c new-file.c
Also, it is helpful if you create the patch in the top level of the
XEmacs source directory:
$ cp -p lwlib/xlwmenu.c lwlib/xlwmenu.c.orig
hack, hack, hack....
$ diff -u lwlib/xlwmenu.c.orig lwlib/xlwmenu.c
It is preferrable for patches to be accompanied by an update (raw
entry preferred) to the appropriate ChangeLog file. Patches to
ChangeLog files have an extremely high rate of failure.
Also note that if you cut & paste from an xterm to an XEmacs mail buffer
you will probably lose due to tab expansion. The best thing to do is
to use an XEmacs shell buffer to run the diff commands, or ...
M-x cd to the appropriate directory, and issue the command `C-u M-!' from
* XEmacs 21 packages
XEmacs 21 has added the concept of installable packages searched prior
to dump time when building.
Packages are searched by default under /usr/local/lib/xemacs/packages/.
The summary message in configure will tell you where XEmacs is looking
for them. The packages hierarchy differs from site-lisp in that you
do not have to install XEmacs to use it. Indeed, the package path is
searched prior to dump time so that installed packages have the same
status as lisp distributed in the xemacs core tarball.
The structure of each directory in the package search path should look
like the base installed directory (ie. have etc/, info/, and lisp/,).
Lisp is searched recursively. It and all subdirectories are added to
the `load-path'. Each etc directory is added to `data-directory-list',
and each info directory is added to `Info-default-directory-list'.
A `find . -type d -print' in my top-level package directory reveals:
AUCTeX and Gnus have package tarballs in
that you can simply untar in a package directory to install.
** Packages directory on the FTP Site
The packages directory
is divided into subdirectory by the major type of package.
drwxr-xr-x 2 beta-f beta-f 1024 Oct 10 00:43 binary-packages
drwxr-xr-x 2 beta-f beta-f 512 Oct 10 00:44 package-sources
drwxr-xr-x 2 beta-f beta-f 512 Oct 10 00:44 utils
** Support Utilities (utils)
The utils directory contains tools to deal with current Lisp sources that
have not had yet gotten XEmacs package integration. The script `xpackage.sh'
is used with Quassia Gnus. Edit the appropriate variables at the top of
the script to reflect the local configuration and run it in the top level
directory of a Quassia Gnus source tree to install an update to Quassia Gnus.
** Binary package installation (binary-packages)
Prerequisite: XEmacs 21.0-b1.
Binary packages are complete entities that can be untarred at the top
level of an XEmacs package hierarchy and work at runtime. To install files
in this directory, run the command `M-x package-admin-add-binary-package'
and fill in appropriate values to the prompts.
** Manual procedures for package management
Prerequisite: XEmacs 21.0
When adding and deleting files from a lisp directory the
auto-autoloads.el (global symbols) and custom-load.el (Customization
groups) must be kept in synch. Assuming one is manipulating a
directory called `lisp-utils', the command to rebuild the
auto-autoloads.el file is:
xemacs-21.0 -vanilla -batch -l autoload -f batch-update-directory lisp-utils
The command to rebuild the custom-load.el file is:
xemacs-21.0 -vanilla -batch -l cus-dep \
-f Custom-make-dependencies lisp-utils
To bytecompile both of these files the command is:
xemacs-21.0 -vanilla -batch -f batch-byte-compile \
** Building XEmacs and XEmacs packages from scratch
To build everything completely from scratch (not a high priority as a
design goal), the following procedure should work. (I don't recommend
building this way).
*** Phase 1 -- Get a minimal XEmacs binary with mule to build the package
**** Grab a mule-base tarball and install it into a newly created package
**** Configure XEmacs with mule and a package-path including the
directory created above.
**** Do a `make dist' to build an XEmacs binary.
*** Phase 2 -- Build and install the package lisp.
**** Modify XEmacs.rules for local paths and the XEmacs binary created in
**** Do a make from the top level package lisp source directory.
**** Do `make bindist's on all the packages you wish to install and
remove the byproduct .tar.gz's.
*** Phase 3 -- Redump XEmacs with the packages that require dump time
support (like egg-its, VM, etc.) and install it.
**** Reconfigure without Mule if you don't wish a Mule-ish XEmacs, and
- or -
**** rm lib-src/DOC src/xemacs; make
**** Install or run in-place.
Note that this is in essence what `make all-elc' has always done.
