INSTALL.REPO

   1              Building and Installing Emacs from the Repository
   2
   3 Simply run 'make'.  This should work if your files are freshly checked
   4 out from the repository, and if you have the proper tools installed.
   5 If it doesn't work, or if you have special build requirements, the
   6 following information may be helpful.
   7
   8 Building Emacs from the source-code repository requires some tools
   9 that are not needed when building from a release.  You will need:
  10
  11 autoconf  - at least the version specified near the start of
  12   configure.ac (in the AC_PREREQ command).
  13 automake  - at least the version specified near the start of
  14   configure.ac (in the AM_INIT_AUTOMAKE command).
  15 pkg-config - at least version specified in the PKG_PROG_PKG_CONFIG
  16   command in configure.ac
  17 makeinfo  - not strictly necessary, but highly recommended, so that
  18   you can build the manuals.
  19
  20 To use the autotools, run the following shell command to generate the
  21 'configure' script and some related files:
  22
  23   $ ./autogen.sh
  24
  25 You can then configure your build as follows:
  26
  27   $ ./configure
  28
  29 The 'configure' script has many options; run './configure --help' to
  30 see them.  For example, if you want later builds to go faster, albeit
  31 sometimes doing the wrong thing if you update the build procedure, you
  32 can invoke './configure -C'.  After configuring, build Emacs as follows:
  33
  34   $ make
  35
  36 If you want to install Emacs, type 'make install' instead of 'make' in
  37 the last command.
  38
  39 Occasionally the file 'lisp/loaddefs.el' (and similar automatically
  40 generated files, such as 'esh-groups.el', and '*-loaddefs.el' in some
  41 subdirectories of 'lisp/', e.g., 'mh-e/' and 'calendar/') will need to be
  42 updated to reflect new autoloaded functions.  If you see errors (rather
  43 than warnings) about undefined lisp functions during compilation, that
  44 may be the reason.  Finally, sometimes there can be build failures
  45 related to '*loaddefs.el' (e.g., "required feature `esh-groups' was not
  46 provided").  In that case, follow the instructions below.
  47
  48 To update loaddefs.el (and similar files), do:
  49
  50   $ cd lisp
  51   $ make autoloads
  52
  53 If either of the above partial procedures fails, try 'make bootstrap'.
  54 If CPU time is not an issue, 'make bootstrap' is the most thorough way
  55 to rebuild, and avoid any spurious problems.
  56
  57 Users of non-Posix systems (MS-Windows, etc.) should run the
  58 platform-specific configuration scripts ('nt/configure.bat',
  59 'config.bat', etc.) before 'make'; the rest of the procedure is
  60 applicable to those systems as well.
  61
  62 Because the repository version of Emacs is a work in progress, it will
  63 sometimes fail to build.  Please wait a day or so (and check the
  64 archives of the emacs-buildstatus, emacs-devel, and bug-gnu-emacs
  65 mailing lists) before reporting such problems.  In most cases, the
  66 problem is known about and is just waiting for someone to fix it.
  67 This is especially true for Lisp compilation errors, which are almost
  68 never platform-specific.
