* autogen.sh (do_autoconf, do_git): New vars. Support new arguments --help, all, autoconf, git. By default, just do autoconf-related configuration, not git. Prefer 'echo' to 'cat <<EOF ...', as this tends to avoid temp files. If GNU cp is available, use it to backup .git/config before changing it. When configuring git, chatter about what is being done, and configure git to check hashes. Avoid some duplicate file name specification when creating git hooks. * GNUmakefile (ALL_IF_GIT): New macro. (configure): Use it. * INSTALL.REPO: Suggest './autogen.sh all'.

Building and Installing Emacs from the Repository
|
||
|
||
Simply run 'make'. This should work if your files are freshly checked
|
||
out from the repository, and if you have the proper tools installed.
|
||
If it doesn't work, or if you have special build requirements, the
|
||
following information may be helpful.
|
||
|
||
Building Emacs from the source-code repository requires some tools
|
||
that are not needed when building from a release. You will need:
|
||
|
||
autoconf - at least the version specified near the start of
|
||
configure.ac (in the AC_PREREQ command).
|
||
automake - at least the version specified near the start of
|
||
configure.ac (in the AM_INIT_AUTOMAKE command).
|
||
git - at least Git 1.7.1. If your repository was created by an older
|
||
Git version, you may need to reclone it.
|
||
makeinfo - not strictly necessary, but highly recommended, so that
|
||
you can build the manuals.
|
||
|
||
To use the autotools, run the following shell command to generate the
|
||
'configure' script and some related files, and to set up your git
|
||
configuration:
|
||
|
||
$ ./autogen.sh all
|
||
|
||
You can then configure your build as follows:
|
||
|
||
$ ./configure
|
||
|
||
The 'configure' script has many options; run './configure --help' to
|
||
see them. For example, if you want later builds to go faster, albeit
|
||
sometimes doing the wrong thing if you update the build procedure, you
|
||
can invoke './configure -C'. After configuring, build Emacs as follows:
|
||
|
||
$ make
|
||
|
||
If you want to install Emacs, type 'make install' instead of 'make' in
|
||
the last command.
|
||
|
||
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. 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 (and similar files), do:
|
||
|
||
$ cd lisp
|
||
$ make autoloads
|
||
|
||
If either of the above partial procedures fails, try 'make bootstrap'.
|
||
If CPU time is not an issue, 'make bootstrap' is the most thorough way
|
||
to rebuild, and avoid any spurious problems.
|
||
|
||
Because the repository version of Emacs is a work in progress, it will
|
||
sometimes fail to build. Please wait a day or so (and check the
|
||
archives of the emacs-buildstatus, emacs-devel, and bug-gnu-emacs
|
||
mailing lists) before reporting such problems. In most cases, the
|
||
problem is known about and is just waiting for someone to fix it.
|
||
This is especially true for Lisp compilation errors, which are almost
|
||
never platform-specific.
