7 This is a list of the status of GNU Emacs on various machines and systems.
9 Information about older releases, and platforms that are no longer
10 supported, has been removed. Consult older versions of this file if
11 you are interested in this information.
13 The `configure' script uses the configuration name, and the results of
14 testing the system, to decide which options to use in src/config.h and
15 elsewhere (eg Makefiles).
17 If you add support for a new configuration, add a section to this
18 file, and edit the `configure.ac' source as needed.
20 Some obsolete platforms are unsupported beginning with Emacs 23.1. See
21 the list at the end of this file.
24 * Here are notes about some of the systems supported:
28 Most of the complete systems which use the Linux kernel are close
29 enough to the GNU system to be considered variant GNU systems. We
30 call them "Linux-based GNU systems," or GNU/Linux for short.
32 It is not coincidence that many of the other components used with
33 Linux--including GNU Emacs--were developed specifically for the GNU
34 project. The GNU project was launched in 1984 to develop a free
35 complete Unix-like operating system. To reach this goal, we had to
36 develop whatever system components were not available as freely
37 redistributable software from some other source.
39 The GNU project wants users of GNU/Linux systems to be aware of how
40 these systems relate to the GNU project, because that will help
41 spread the GNU idea that software should be free--and thus encourage
42 people to write more free software. For more information, see
43 <http://www.gnu.org/gnu/linux-and-gnu.html>.
47 No special procedures should be needed to build a 64-bit Emacs on a
48 64-bit GNU/Linux system. To build a 32-bit Emacs, first ensure that
49 the necessary 32-bit system libraries and include files are
52 ./configure CC='gcc -m32' --build=i386-linux-gnu \
53 --x-libraries=/usr/X11R6/lib
55 (using the location of the 32-bit X libraries on your system).
57 *** IBM System/390 running GNU/Linux (s390-*-linux-gnu)
59 As of Emacs 21.2, a 31-bit only version is supported on this system.
61 *** SuperH (sh[34]*-*-linux-gnu)
63 Emacs 23.0.60 was reported to work on GNU/Linux (October 2008).
64 This was tested on a little-endian sh4 system (cpu type SH7751R) running
69 Version 10.6 or newer. PowerPC is not supported.
70 For installation instructions see the file nextstep/INSTALL.
74 For installation instructions see the file nt/INSTALL.
78 For installation instructions see the file msdos/INSTALL.
79 See the "MS-DOS" chapter of the manual for information about using
84 On Solaris it is also possible to use either GCC or Solaris Studio
85 to build Emacs, by pointing ./configure to the right compiler:
87 ./configure CC='/usr/sfw/bin/gcc' # GCC
88 ./configure CC='cc' # Solaris Studio
90 On Solaris, do not use /usr/ucb/cc. Use /opt/SUNWspro/bin/cc. Make
91 sure that /usr/ccs/bin and /opt/SUNWspro/bin are in your PATH before
92 /usr/ucb. (Most free software packages have the same requirement on
93 Solaris.) With this compiler, use `/opt/SUNWspro/bin/cc -E' as the
94 preprocessor. If this inserts extra whitespace into its output (see
95 the PROBLEMS file) then add the option `-Xs'.
97 To build a 64-bit Emacs (with larger maximum buffer size) on a
98 Solaris system which supports 64-bit executables, specify the -m64
99 compiler option. For example:
101 ./configure CC='/usr/sfw/bin/gcc -m64' # GCC
102 ./configure CC='cc -m64' # Solaris Studio
106 Emacs versions later than 24.4 will not compile on Irix by default.
107 (Note that SGI stopped supporting Irix in December 2013.)
108 You should be able to work around the problem either by porting the
109 Emacs undumping code to GCC under Irix, or by configuring --with-wide-int.
110 Older versions of Emacs 24 (and 23?) also had problems on Irix.
111 It *may* be possible to build Emacs <= 24.4 on Irix 6.5 with an old
112 version (3.1) of gcc. Newer versions of gcc may not work.
113 See <http://debbugs.gnu.org/9684>.
118 Support for many obsolete platforms was removed in Emacs 23.1.
119 If for some reason you encounter an ancient machine where current
120 Emacs does not compile, try an older release like Emacs 22.3.
