| 7 | This is a list of the status of GNU Emacs on various machines and systems. |
| 8 | |
| 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. |
| 12 | |
| 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). |
| 16 | |
| 17 | If you add support for a new configuration, add a section to this |
| 18 | file, and edit the `configure.ac' source as needed. |
| 19 | |
| 20 | Some obsolete platforms are unsupported beginning with Emacs 23.1. See |
| 21 | the list at the end of this file. |
| 22 | |

| 24 | * Here are notes about some of the systems supported: |
| 25 | |
| 26 | ** GNU/Linux |
| 27 | |
| 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. |
| 31 | |
| 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. |
| 38 | |
| 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>. |
| 44 | |
| 45 | *** 64-bit GNU/Linux |
| 46 | |
| 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 |
| 50 | installed. Then use: |
| 51 | |
| 52 | ./configure CC='gcc -m32' --build=i386-linux-gnu \ |
| 53 | --x-libraries=/usr/X11R6/lib |
| 54 | |
| 55 | (using the location of the 32-bit X libraries on your system). |
| 56 | |
| 57 | *** IBM System/390 running GNU/Linux (s390-*-linux-gnu) |
| 58 | |
| 59 | As of Emacs 21.2, a 31-bit only version is supported on this system. |
| 60 | |
| 61 | *** SuperH (sh[34]*-*-linux-gnu) |
| 62 | |
| 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 |
| 65 | Gentoo Linux 2008.0. |
| 66 | |
| 67 | ** Mac OS X |
| 68 | |
| 69 | For installation instructions see the file nextstep/INSTALL. |
| 70 | |
| 71 | ** Microsoft Windows |
| 72 | |
| 73 | For installation instructions see the file nt/INSTALL. |
| 74 | |
| 75 | ** MS-DOS |
| 76 | |
| 77 | For installation instructions see the file msdos/INSTALL. |
| 78 | See the "MS-DOS" chapter of the manual for information about using |
| 79 | Emacs on MS-DOS. |
| 80 | |
| 81 | ** Solaris |
| 82 | |
| 83 | On Solaris it is also possible to use either GCC or Solaris Studio |
| 84 | to build Emacs, by pointing ./configure to the right compiler: |
| 85 | |
| 86 | ./configure CC='/usr/sfw/bin/gcc' # GCC |
| 87 | ./configure CC='cc' # Solaris Studio |
| 88 | |
| 89 | On Solaris, do not use /usr/ucb/cc. Use /opt/SUNWspro/bin/cc. Make |
| 90 | sure that /usr/ccs/bin and /opt/SUNWspro/bin are in your PATH before |
| 91 | /usr/ucb. (Most free software packages have the same requirement on |
| 92 | Solaris.) With this compiler, use `/opt/SUNWspro/bin/cc -E' as the |
| 93 | preprocessor. If this inserts extra whitespace into its output (see |
| 94 | the PROBLEMS file) then add the option `-Xs'. |
| 95 | |
| 96 | To build a 64-bit Emacs (with larger maximum buffer size) on a |
| 97 | Solaris system which supports 64-bit executables, specify the -m64 |
| 98 | compiler option. For example: |
| 99 | |
| 100 | ./configure CC='/usr/sfw/bin/gcc -m64' # GCC |
| 101 | ./configure CC='cc -m64' # Solaris Studio |
| 102 | |
| 103 | ** Irix 6.5 |
| 104 | |
| 105 | Emacs versions later than 24.4 will not compile on Irix by default. |
| 106 | (Note that SGI stopped supporting Irix in December 2013.) |
| 107 | You should be able to work around the problem either by porting the |
| 108 | Emacs undumping code to GCC under Irix, or by configuring --with-wide-int. |
| 109 | Older versions of Emacs 24 (and 23?) also had problems on Irix. |
| 110 | It *may* be possible to build Emacs <= 24.4 on Irix 6.5 with an old |
| 111 | version (3.1) of gcc. Newer versions of gcc may not work. |
| 112 | See <http://debbugs.gnu.org/9684>. |
| 113 | |
| 114 | \f |
| 115 | * Obsolete platforms |
| 116 | |
| 117 | Support for many obsolete platforms was removed in Emacs 23.1. |
| 118 | If for some reason you encounter an ancient machine where current |
| 119 | Emacs does not compile, try an older release like Emacs 22.3. |
| 120 | |
| 121 | \f |
| 122 | Local variables: |
| 123 | mode: outline |
| 124 | fill-prefix: " " |
