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" 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. To update loaddefs.el, do: $ cd lisp $ make autoloads EMACS=../src/emacs If either of the above partial procedures fails, try "make bootstrap". 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 email@example.com 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 User YOUR_USERID This file is part of GNU Emacs.
