1Emacs machines list 2 3Copyright (C) 1989-1990, 1992-1993, 1998, 2001-2021 Free Software 4Foundation, Inc. 5See the end of the file for license conditions. 6 7This is a list of the status of GNU Emacs on various machines and systems. 8 9Information about older releases, and platforms that are no longer 10supported, has been removed. Consult older versions of this file if 11you are interested in this information. 12 13The 'configure' script uses the configuration name, and the results of 14testing the system, to decide which options to use in src/config.h and 15elsewhere (eg Makefiles). 16 17If you add support for a new configuration, add a section to this 18file, and edit the 'configure.ac' source as needed. 19 20Some obsolete platforms are unsupported beginning with Emacs 23.1. See 21the list at the end of this file. 22 23 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 <https://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** macOS 68 69 Mac OS X 10.6 or newer. PowerPC is not supported. 70 For installation instructions see the file nextstep/INSTALL. 71 72** Microsoft Windows 73 74 For installation instructions see the file nt/INSTALL. 75 76** MS-DOS 77 78 For installation instructions see the file msdos/INSTALL. 79 See the "MS-DOS" chapter of the manual for information about using 80 Emacs on MS-DOS. 81 82** Solaris 83 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: 86 87 ./configure CC='/usr/sfw/bin/gcc' # GCC 88 ./configure CC='cc' # Solaris Studio 89 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'. 96 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: 100 101 ./configure CC='/usr/sfw/bin/gcc -m64' # GCC 102 ./configure CC='cc -m64' # Solaris Studio 103 104 105* Obsolete platforms 106 107Support for many obsolete platforms was removed in Emacs 23.1. 108If for some reason you encounter an ancient machine where current 109Emacs does not compile, try an older release like Emacs 22.3. 110 111 112Local variables: 113mode: outline 114fill-prefix: " " 115End: 116 117This file is part of GNU Emacs. 118 119GNU Emacs is free software: you can redistribute it and/or modify 120it under the terms of the GNU General Public License as published by 121the Free Software Foundation, either version 3 of the License, or 122(at your option) any later version. 123 124GNU Emacs is distributed in the hope that it will be useful, 125but WITHOUT ANY WARRANTY; without even the implied warranty of 126MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
