Building and Installing Emacs from the Repository
|
||
|
||
The Emacs repository is hosted on Savannah. The following Git command
|
||
will clone the repository to the 'emacs' subdirectory of the current
|
||
directory on your local machine:
|
||
|
||
git clone git://git.sv.gnu.org/emacs.git
|
||
|
||
To build the repository code, simply run 'make' in the 'emacs'
|
||
directory. This should work if your files are freshly checked out
|
||
from the repository, and if you have the proper tools installed; the
|
||
default configuration options will be used. Other configuration
|
||
options can be specified by setting a 'configure' variable, for
|
||
example:
|
||
|
||
$ make configure="--prefix=/opt/emacs CFLAGS='-O0 -g3'"
|
||
|
||
If the above 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).
|
||
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. GNU Texinfo 4.13 or later should work.
|
||
|
||
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
|
||
|
||
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
|
||
|
||
You can also type 'make check' to test and 'make install' to install
|
||
Emacs.
|
||
|
||
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 a more thorough way
|
||
to rebuild, avoiding spurious problems. 'make bootstrap' rebuilds
|
||
Emacs with the same configuration options as the previous build; it
|
||
can also be used to rebuild Emacs with other configuration options by
|
||
setting a 'configure' variable, for example:
|
||
|
||
$ make bootstrap configure="CFLAGS='-O0 -g3'"
|
||
|
||
To rebuild Emacs with the default configuration options, you can use:
|
||
|
||
$ make bootstrap configure=default
|
||
|
||
Occasionally, there are changes that 'make bootstrap' won't be able to
|
||
handle. The most thorough cleaning can be achieved by 'git clean -fdx'
|
||
which will leave you with only files from the git repository. Here
|
||
are some faster methods for a couple of particular error cases:
|
||
|
||
/usr/bin/m4:aclocal.m4:9: cannot open `m4/count-leading-zeros.m4': No such file or directory
|
||
|
||
This can be fixed with 'rm aclocal.m4'.
|
||
|
||
make: *** No rule to make target 'lib/Makefile.am', needed by 'lib/Makefile.in'
|
||
|
||
This can be fixed with 'rm lib/Makefile Makefile'.
|
||
|
||
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.
