Building and Installing Emacs from CVS
|
||
|
||
Some of the files that are included in the Emacs tarball, such as
|
||
byte-compiled Lisp files, are not stored in the CVS repository.
|
||
Therefore, to build from CVS you must run "make bootstrap"
|
||
instead of just "make":
|
||
|
||
$ ./configure
|
||
$ make bootstrap
|
||
|
||
The bootstrap process makes sure all necessary files are rebuilt
|
||
before it builds the final Emacs binary.
|
||
|
||
Normally, it is not necessary to use "make bootstrap" after every CVS
|
||
update. Unless there are problems, we suggest using the following
|
||
alternative procedure after you have done "make bootstrap" at least
|
||
once:
|
||
|
||
$ ./configure
|
||
$ make
|
||
$ cd lisp
|
||
$ make recompile EMACS=../src/emacs
|
||
$ cd ..
|
||
$ make
|
||
|
||
(If you want to install the Emacs binary, type "make install" instead
|
||
of "make" in the last command.)
|
||
|
||
Occasionally the file "lisp/loaddefs.el" (and similar *-loaddefs.el
|
||
files in some subdirectories of lisp/, e.g. mh-e/ and calendar/) will
|
||
need to be updated to reflect new autoloaded functions. If you see
|
||
errors (rather than warnings) about undefined lisp functions during
|
||
compilation, that may be the reason. Another symptom may be an error
|
||
saying that "loaddefs.el" could not be found; this is due to a change
|
||
in the way loaddefs.el was handled in CVS, and should only happen
|
||
once, for users that are updating old CVS trees. Finally, sometimes
|
||
there can be build failures related to *loaddefs.el. In that case,
|
||
delete them before following the instructions below to update them.
|
||
|
||
To update loaddefs.el (and similar files), do:
|
||
|
||
$ cd lisp
|
||
$ make autoloads EMACS=../src/emacs
|
||
|
||
If either of the above partial procedures fails, try "make bootstrap".
|
||
|
||
Very occasionally changes in the source can introduce
|
||
incompatibilities with previous builds. If a bootstrap fails, as a
|
||
last resort try "make maintainer-clean" before configuring and
|
||
bootstrapping again. If CPU time is not an issue, the most thorough
|
||
way to rebuild, and avoid any spurious problems, is always to use this
|
||
method.
|
||
|
||
Users of non-Posix systems (MS-Windows etc.) should run the
|
||
platform-specific configuration scripts (nt/configure.bat, config.bat,
|
||
etc.) before "make bootstrap" or "make"; the rest of the procedure is
|
||
applicable to those systems as well, except that the value of the
|
||
EMACS variable on the Make command line might be different, e.g.,
|
||
../bin/emacs.exe or some such.
|
||
|
||
Questions, requests, and bug reports about the CVS versions of Emacs
|
||
should be sent to emacs-pretest-bug@gnu.org rather than gnu.emacs.help
|
||
or gnu.emacs.bug. Ideally, use M-x report-emacs-bug RET which will
|
||
send it to the proper place.
|
||
|
||
|
||
Note on using SSH to access the CVS repository from inside Emacs
|
||
----------------------------------------------------------------
|
||
|
||
Write access to the CVS repository requires using SSH v2.
|
||
|
||
If you execute cvs commands inside Emacs, specifically if you use
|
||
pcl-cvs, output from CVS may be lost due to a problem in the
|
||
interface between ssh, cvs, and libc. Corrupted checkins are
|
||
also known to have happened.
|
||
|
||
To fix the problem, save the following script into a file, make it
|
||
executable, and set CVS_RSH to the file name of the script:
|
||
|
||
#!/bin/bash
|
||
exec 2> >(exec cat >&2 2>/dev/null)
|
||
exec ssh "$@"
|
||
|
||
This may be combined with the following entry in ~/.ssh/config to
|
||
simplify accessing the CVS repository:
|
||
|
||
Host subversions.gnu.org
|
||
Protocol 2
|
||
ForwardX11 no
|
||
