Building and Installing Emacs from CVS
Some of the files that are included in the Emacs tarball, such as
Therefore, to build from CVS you must run "make bootstrap"
instead of just "make":
+ $ cvs update -dP
$ ./configure
$ make bootstrap
The bootstrap process makes sure all necessary files are rebuilt
-before it builds the final Emacs binary.
+before it builds the final Emacs binary. Unfortunately, it doesn't
+always work when there are stale files from a previous build in the
+directory tree.
+
+So if 'make bootstrap' fails, it may be necessary first to do 'make
+maintainer-clean' to clear out these stale files. You can then try
+again, starting with `./configure'.
Normally, it is not necessary to use "make bootstrap" after every CVS
-update. Unless there are problems, we suggest the following
-procedure:
+update. Unless there are problems, we suggest using the following
+alternative procedure after you have done "make bootstrap" at least
+once:
$ ./configure
$ 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" will need be updated to
-reflect new autoloaded functions. If you see errors 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.
+Occasionally the file "lisp/loaddefs.el" (and similar automatically
+generated files, such as esh-groups.el, and *-loaddefs.el 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 (e.g. "required feature `esh-groups'
+was not provided"). In that case, follow the instructions below.
-To update loaddefs.el, do:
+To update loaddefs.el (and similar files), do:
$ cd lisp
+ $ make autogen-clean
$ 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

pcl-cvs, output from CVS may be lost due to a problem in the

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:
