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 | |
f71e87cb | 18 | file, and edit the `configure.ac' source as needed. |

ad5a7209 | 24 | * Here are notes about some of the systems supported: |
f4b79972 | 25 | |
393aa9d4 | 26 | ** GNU/Linux |
f4b79972 EZ |
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 | |
00156f95 GM |
42 | people to write more free software. For more information, see |
43 | <http://www.gnu.org/gnu/linux-and-gnu.html>. | |

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 | ||
ad5a7209 | 67 | ** Mac OS X |
f4b79972 | 68 | |
ad5a7209 | 69 | For installation instructions see the file nextstep/INSTALL. |
f4b79972 | 70 | |
393aa9d4 | 71 | ** Microsoft Windows |
f4b79972 | 72 | |
393aa9d4 PE |
73 | For installation instructions see the file nt/INSTALL. |
74 | ||
75 | ** MS-DOS | |
76 | ||
77 | For installation instructions see the file msdos/INSTALL. | |
ad5a7209 | 78 | See the "MS-DOS" chapter of the manual for information about using |
393aa9d4 | 79 | Emacs on MS-DOS. |
f4b79972 | 80 | |
393aa9d4 | 81 | ** Solaris |
f4b79972 | 82 | |
393aa9d4 PE |
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: | |
f4b79972 | 85 | |
393aa9d4 PE |
86 | ./configure CC='/usr/sfw/bin/gcc' # GCC |
87 | ./configure CC='cc' # Solaris Studio | |
745377e8 | 88 | |
393aa9d4 PE |
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'. | |
745377e8 | 95 | |
393aa9d4 PE |
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: | |
745377e8 | 99 | |
393aa9d4 PE |
100 | ./configure CC='/usr/sfw/bin/gcc -m64' # GCC |
101 | ./configure CC='cc -m64' # Solaris Studio | |

103 | ** Irix 6.5 |
104 | ||
b35883d2 GM |
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>. | |

115 | * Obsolete platforms | |
116 | ||
b35883d2 GM |
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. | |
