This is a list of the status of GNU Emacs on various machines and systems.

Information about older releases, and platforms that are no longer
supported, has been removed.  Consult older versions of this file if
you are interested in this information.

The `configure' script uses the configuration name to decide which
machine and operating system description files `src/config.h' should
include.  The machine description files are all in `src/m', and have
names similar to, but not identical to, the machine names used in
configuration names.  The operating system files are all in `src/s',
and are named similarly.  See the `configure' script if you need to
know which configuration names use which machine and operating system
description files.

If you add support for a new configuration, add a section to this
file, and then edit the `configure' script to tell it which
configuration name(s) should select your new machine description and
system description files.

Some obsolete platforms are unsupported beginning with Emacs 23.1.  See
the list at the end of this file.


* Here are notes about some of the systems supported:

** GNU/Linux

  Most of the complete systems which use the Linux kernel are close
  enough to the GNU system to be considered variant GNU systems.  We
  call them "Linux-based GNU systems," or GNU/Linux for short.

  It is not coincidence that many of the other components used with
  Linux--including GNU Emacs--were developed specifically for the GNU
  project.  The GNU project was launched in 1984 to develop a free
  complete Unix-like operating system.  To reach this goal, we had to
  develop whatever system components were not available as freely
  redistributable software from some other source.

  The GNU project wants users of GNU/Linux systems to be aware of how
  these systems relate to the GNU project, because that will help
  spread the GNU idea that software should be free--and thus encourage
  people to write more free software.  See the file LINUX-GNU in this
  directory for more explanation.

*** 64-bit GNU/Linux

  No special procedures should be needed to build a 64-bit Emacs on a
  64-bit GNU/Linux system.  To build a 32-bit Emacs, first ensure that
  the necessary 32-bit system libraries and include files are
  installed.  Then use:

    ./configure CC='gcc -m32' --build=i386-linux-gnu \
      --x-libraries=/usr/X11R6/lib

  (using the location of the 32-bit X libraries on your system).

*** IBM System/390 running GNU/Linux (s390-*-linux-gnu)

  As of Emacs 21.2, a 31-bit only version is supported on this system.

*** SuperH (sh[34]*-*-linux-gnu)

  Emacs 23.0.60 was reported to work on GNU/Linux (October 2008).
  This was tested on a little-endian sh4 system (cpu type SH7751R) running
  Gentoo Linux 2008.0.

** Mac OS X

  For installation instructions see the file nextstep/INSTALL.

** Microsoft Windows

  For installation instructions see the file nt/INSTALL.

** MS-DOS

  For installation instructions see the file msdos/INSTALL.
  See the "MS-DOS" chapter of the manual for information about using
  Emacs on MS-DOS.

** Solaris

  On Solaris it is also possible to use either GCC or Solaris Studio
  to build Emacs, by pointing ./configure to the right compiler:

    ./configure CC='/usr/sfw/bin/gcc'  # GCC
    ./configure CC='cc'                # Solaris Studio

  On Solaris, do not use /usr/ucb/cc.  Use /opt/SUNWspro/bin/cc.  Make
  sure that /usr/ccs/bin and /opt/SUNWspro/bin are in your PATH before
  /usr/ucb.  (Most free software packages have the same requirement on
  Solaris.)  With this compiler, use `/opt/SUNWspro/bin/cc -E' as the
  preprocessor.  If this inserts extra whitespace into its output (see
  the PROBLEMS file) then add the option `-Xs'.

  To build a 64-bit Emacs (with larger maximum buffer size) on a
  Solaris system which supports 64-bit executables, specify the -m64
  compiler option.  For example:

    ./configure CC='/usr/sfw/bin/gcc -m64'  # GCC
    ./configure CC='cc -m64'                # Solaris Studio
