7 This is a list of the status of GNU Emacs on various machines and systems.
9 For each system and machine, we give the configuration name you should
10 pass to the `configure' script to prepare to build Emacs for that
13 The `configure' script uses the configuration name to decide which
14 machine and operating system description files `src/config.h' should
15 include. The machine description files are all in `src/m', and have
16 names similar to, but not identical to, the machine names used in
17 configuration names. The operating system files are all in `src/s',
18 and are named similarly. See the `configure' script if you need to
19 know which configuration names use which machine and operating system
22 If you add support for a new configuration, add a section to this
23 file, and then edit the `configure' script to tell it which
24 configuration name(s) should select your new machine description and
25 system description files.
27 Some obsolete platforms are unsupported beginning with Emacs 23.1, see
28 the full list at the end of this file.
31 Here are the configurations Emacs is intended to work with, with the
32 corresponding configuration names. You can postpend version numbers
33 to operating system names (i.e. sunos4.1) or architecture names (i.e.
34 hppa1.1). If you leave out the version number, the `configure' script
35 will configure Emacs for the latest version it knows about.
37 Alpha (DEC) running GNU/Linux (alpha-dec-linux-gnu)
39 DEC C compiler version 5.9 (DEC C V5.9-005 on Digital UNIX V4.0f)
40 is reported to produce bogus binaries of Emacs 21.2 when the
41 command-line switches "-O4 -arch ev6 -tune ev6" are used. Using
42 just -O4 produces a good executable.
44 For 4.0 revision 564, and 4.0A and 4.0B, Emacs 20 seems to work
45 with no special configuration options. However, if you use GCC as
46 your compiler, you will need version 2.8.1 or later, as older
47 versions fail to build with a message "Invalid dimension for the
50 Note that the X11 libraries on GNU/Linux systems for the Alpha are
51 said to have bugs that prevent Emacs from working with X (as of
52 November 1995). Recent releases work (July 2000).
54 Apple Macintosh running Mac OS X
56 For installation on all versions of the Mac OS platform, see the file
59 Apple PowerPC Macintosh running GNU/Linux
61 There are special considerations for a variety of this system which
62 is known as the ``Yellow Dog [GNU/]Linux'': Emacs may crash during
63 dumping. To solve this, edit the header file src/m/macppc.h in the
64 Emacs distribution, and remove the "#if 0" and "#endif" directives
65 which surround the following block near the end of the file:
67 #if 0 /* This breaks things on PPC GNU/Linux except for Yellowdog,
68 even with identical GCC, as, ld. Let's take it out until we
69 know what's really going on here. */
70 /* GCC 2.95 and newer on GNU/Linux PPC changed the load address to
73 #if __GNUC__ > 2 || (__GNUC__ == 2 && __GNUC_MINOR__ >= 95)
74 #define DATA_SEG_BITS 0x10000000
79 After that, reconfigure and rebuild Emacs. It should now build
82 Cubix QBx/386 (i386-cubix-sysv)
84 Changes merged in 19.1. Systems before 2/A/0 may fail to compile etags.c
85 due to a compiler bug.
87 DECstation (mips-dec-ultrix or mips-dec-osf)
89 This machine is the older Mips-based DECstation.
90 Emacs should now work on the Alpha CPU.
92 19.25 works on Ultrix 4.2. The 19.26 pretest was reported to work
93 on Ultrix 4.2a and on 4.4.
95 One user reported 19.25 did not work at all with --with-x-toolkit
96 using X11R5 patch level 10, but worked ok with X11R5 pl26.
98 See under Ultrix for problems using X windows on Ultrix.
99 Note that this is a MIPS machine.
101 For Ultrix versions 4.1 or earlier, you may need to define
102 SYSTEM_MALLOC in `src/m/pmax.h', because XvmsAlloc.o in libX11.a seems
103 to insist on defining malloc itself.
105 For Ultrix versions prior to 4.0, you may need to delete
106 the definition of START_FILES from `src/m/pmax.h'.
108 Motorola Delta 147 (m68k-motorola-sysv)
110 The EMacs 19.26 pretest was reported to work.
112 Motorola Delta boxes running System V/68 release 3.
113 Tested on 147 board with SVR3V7, no X and gcc.
114 Tested on 167 board with SVR3V7, no X, cc, gnucc and gcc.
115 Reports say it works with X too.
117 The installation script chooses the compiler itself. gnucc is
120 Fujitsu DS/90 (sparc-fujitsu-sysv4)
122 Changes merged in 20.3.
124 HP 9000 series 500: not supported.
126 The series 500 has a seriously incompatible memory architecture
127 which relocates data in memory during execution of a program,
128 and support for it would be difficult to implement.
130 HP 9000 series 700 or 800 (Spectrum) (hppa1.0-hp-hpux or hppa1.1-hp-hpux
133 Use hppa1.1 for the 700 series and hppa1.0 for the 800
134 series machines. (Emacs may not actually care which one you use.)
136 Emacs 20 may work on HPUX 10. You need patch PHSS_6202 to install
137 the Xaw and Xmu libraries. On HPUX 10.20 you may need to compile with GCC;
138 when Emacs was compiled with HP's C compiler, HP92453-01 A.10.32.03,
139 the subprocess features failed to work.
141 19.26 is believed to work on HPUX 9 provided you compile with GCC.
142 As of version 19.16, Emacs was reported to build (using GCC) and run
143 on HP 9000/700 series machines running HP/UX versions 8.07 and 9.01.
144 The HP compiler is known to fail on some versions if you use +O3,
145 but it may work with lower optimization levels.
147 Use hppa1.1-hp-hpux9shr to use shared libraries on HPUX version 9.
148 You may need to create the X libraries libXaw.a and libXmu.a from
149 the MIT X distribute, and you may need to edit src/Makefile's
150 definition of LIBXT to look like this:
152 LIBXT= $(LIBW) -lXmu -lXt $(LIBXTR6) -lXext
154 Some people report trouble using the GNU memory allocator under
155 HP/UX version 9. The problems often manifest as lots of ^@'s in the
158 We are told that these problems go away if you obtain the latest
159 patches for the HP/UX C compiler. James J Dempsey
160 <jjd@spserv.bbn.com> says that this set of versions works for him:
162 HP92453-01 A.09.28 HP C Compiler
164 HP92453-01 A.09.28 HP C Compiler
165 HP-UX SLLIC/OPTIMIZER HP-UX.09.00.23 02/18/93
166 Ucode Code Generator - HP-UX.09.00.23.5 (patch) 2/18/93
168 For 700 series machines, the HP-UX patch needed is known as
169 PHSS_2653. (Perhaps for 800 series machines as well; we don't
170 know.) If you are on the Internet, you should be able to obtain
171 this patch by using telnet to access the machine
172 support.mayfield.hp.com and logging in as "hpslreg" and following
173 the instructions there. Or you may be able to use this
176 HP Patch Server: http://support.mayfield.hp.com/patches/html/patches.html
177 HP Support Line: http://support.mayfield.hp.com
179 Please do not ask FSF for further support on this. If you have any
180 trouble obtaining the patch, contact HP Software Support.
182 If your buffer fills up with nulls (^@) at some point, it could well
183 be that problem. That problem does not happen when people use GCC
184 to compile Emacs. On the other hand, the HP compiler version 9.34
185 was reported to work for the 19.26 pretest. 9.65 was also reported to work.
187 If you turn on the DSUSP character (delayed suspend),
188 Emacs 19.26 does not know how to turn it off on HPUX.
189 You need to turn it off manually.
191 If you are running HP/UX release 8.0 or later, you need the optional
192 "C/ANSI C" software in order to build Emacs (older releases of HP/UX
193 do not require any special software). If the file "/etc/filesets/C"
194 exists on your machine, you have this software, otherwise you do not.
196 IBM RS/6000 (rs6000-ibm-aix*)
198 Emacs 19.26 is believed to work; its pretest was tested.
200 Compiling with the system's `cc' and CFLAGS containing `-O5' might
201 fail because libXbsd isn't found. This is a compiler bug;
202 re-configure Emacs so that it isn't compiled with `-O5'.
204 On AIX 4.3.x and 4.4, compiling with /bin/c89 fails because it
205 treats certain warnings as errors. Use `cc' instead.
207 At last report, Emacs didn't run well on terminals. Informed
208 persons say that the tty VMIN and VTIME settings have been
209 corrupted; if you have a fix, please send it to us.
211 Compiling with -O using the IBM compiler has been known
212 to make Emacs work incorrectly. It's reported that on
213 AIX 3.2.5 with an IBM compiler earlier than 1.03.00.14,
214 cc -O fails for some files. You need to install any
215 PTF containing APAR #IX42810 to bring the compiler to
216 the 1.03.00.14 level to allow optimized compiles.
218 There are reports that IBM compiler versions earlier than 1.03.00.02
219 fail even without -O. However, another report said that compiler
220 version 1.02.01.00 did work, on AIX 3.2.4, with Emacs 19.31.
222 As of 19.11, if you strip the Emacs executable, it ceases to work.
224 If you are using AIX 3.2.3, you may get a core dump when loading
225 ange-ftp. You may be able to fix the problem by defining LIBS_TERMCAP
226 as -ltermcap -lcurses. Please tell us if this fails to work.
228 If anyone can fix the above problems, or confirm that they don't happen
229 with certain versions of various programs, we would appreciate it.
231 IBM System/390 running GNU/Linux (s390-*-linux-gnu)
233 As of Emacs 21.2, a 31-bit only version is supported on this
236 Intel 386 (i386-*-bsdi2, i386-*-freebsd, i386-*-linux-gnu,
237 i386-*-sol2.4, i386-*-sysv3, i386-intsys-sysv,
238 i386-*-sysv4, i386-*-sysv4.2,
239 i386-*-sysv5.3, i386-*-bsd4.2, i386-*-cygwin,
240 i386-*-bsd386, i386-*-386bsd,
241 i386-*-msdos, i386-*-windowsnt.
242 i386... can be replaced with i486... or i586...)
244 In the above configurations, * means that the manufacturer's name
245 you specify does not matter, and you can use any name you like
246 (but it should not contain any dashes or stars).
248 When using the ISC configurations, be sure to specify the isc
249 version number - for example, if you're running ISC 3.0, use
250 i386-unknown-isc3.0 as your configuration name.
251 Use i386-*-linux-gnu for GNU/Linux systems; Emacs runs as of version 19.26.
252 Use i386-*-cygwin for Cygwin; Emacs builds as of version 22.1, in both X11
253 and non-X11 modes. (The Cygwin site has source and binaries for 21.2.)
254 Use i386-intsys-sysv for Integrated Solutions 386 machines.
255 It may also be correct for Microport systems.
257 On GNU/Linux systems, Emacs 19.23 was said to work properly with libc
258 version 4.5.21, but not with 4.5.19. If your system uses QMAGIC
259 for the executable format, you must edit config.h to define LINUX_QMAGIC.
261 On GNU/Linux, configure may fail to put these definitions in config.h:
263 #define HAVE_GETTIMEOFDAY
266 #define HAVE_XSCREENNUMBEROFSCREEN
268 To work around the problem, add those definitions by hand.
269 It is possible that this problem happens only with X11R6.
270 Newer system versions have fixed it.
272 The 19.26 pretest was reported to work on SVR4.3 and on Freebsd.
274 19.29 is reported to crash when using Motif on Solaris 2.5.
275 The reasons are not yet known.
277 Use i386-*-bsdiN for BSDI BSD/OS version N; Emacs runs as of version 19.23.
278 In some system versions, `make' is broken; use GNU make instead.
279 Shell bugs in version 1.0 of BSD/OS cause configure
280 to do the wrong thing with --with-x-toolkit; the workaround is to edit
281 configure to run another shell such as bash.
283 For System V release 3, use i386-*-sysv3.
284 For System V release 4, use i386-*-sysv4.
285 For System V release 4.2, use i386-*-sysv4.2.
287 If you are using SCO Unix, see notes at end under SCO.
289 On 386bsd, NetBSD and FreeBSD, at one time, it was necessary to use
290 GNU make, not the system's make. Assuming it's installed as gmake,
291 do `gmake install MAKE=gmake'. However, more recently it is
292 reported that using the system Make on NetBSD 1.3.1 works ok.
294 If you are using System V release 4.2, you may find that `cc -E'
295 puts spurious spaces in `src/xmakefile'. If that happens,
296 specify CPP=/lib/cpp as an option when you run make.
297 There is no problem if you compile with GCC.
299 Note that use of Linux with GCC 2.4 and the DLL 4.4 libraries
300 requires the experimental "net 2" network patches (no relation to
301 Berkeley Net 2). There is a report that (some version of) Linux
302 requires including `/usr/src/linux/include/linux' in buffer.c
303 but no coherent explanation of why that might be so. If it is so,
304 in current versions of Linux, something else should probably be changed.
306 Some sysV.3 systems seem to have bugs in `opendir';
307 for them, alter `config.h' to define NONSYSTEM_DIR_LIBRARY
308 and undefine SYSV_SYSTEM_DIR.
310 If you use optimization on V.3, you may need the option -W2,'-y 0'
311 to prevent certain faulty optimization.
313 On 386/ix, to link with shared libraries, add #define USG_SHARED_LIBRARIES
316 On SCO, there are problems in regexp matching when Emacs is compiled
317 with the system compiler. The compiler version is "Microsoft C
318 version 6", SCO 4.2.0h Dev Sys Maintenance Supplement 01/06/93;
319 Quick C Compiler Version 1.00.46 (Beta). The solution is to compile
322 On ISC systems (2.02 and more recent), don't try to use the versions
323 of X that come with the system; use XFree86 instead.
325 There is no consistency in the handling of certain system header files
328 Some versions have sys/sioctl.h, and require it in sysdep.c.
329 But some versions do not have sys/sioctl.h.
330 For a given version of the system, this may depend on whether you have
331 X Windows or TCP/IP. Define or undefine NO_SIOCTL_H in config.h
332 according to whether you have the file.
334 Likewise, some versions have been known to need sys/ttold.h, sys/stream.h,
335 and sys/ptem.h included in sysdep.c. If your system has these files,
336 try defining NEED_PTEM_H in config.h if you have trouble without it.
338 You may find that adding -I/usr/X/include or -I/usr/netinclude or both
339 to CFLAGS avoids compilation errors on certain systems.
341 Some versions convince sysdep.c to try to use `struct tchars'
342 but define `struct tc' instead; add `#define tchars tc'
343 to config.h to solve this problem.
345 Iris 4D (mips-sgi-irix[456].*)
347 Emacs 21.3 is reported to work on IRIX 6.5.x.
349 You can build a 64-bit executable (with larger maximum buffer size)
350 on Irix 6.5 by specifying the 64-bit ABI using the `-64' compiler
351 flag or otherwise (see cc(1)). This may work on earlier Irix 6
352 systems if you edit src/s/irix6-0.h following irix6-5.h.
354 If compiling with GCC on Irix 6 yields an error "conflicting types
355 for `initstate'", install GCC 2.95 or a newer version, and this
356 problem should go away. It is possible that this problem results
357 from upgrading the operating system without reinstalling GCC; so you
358 could also try reinstalling the same version of GCC, and telling us
359 whether that fixes the problem.
361 Mips (mips-mips-riscos, mips-mips-riscos4.0, or mips-mips-bsd)
363 The C compiler on Riscos 4.51 dumps core trying to optimize
364 parts of Emacs. Try without optimization or try GCC.
366 Meanwhile, the linker on that system returns success even if
367 there are undefined symbols; as a result, configure gets the
368 wrong answers to various questions. No work-around is known
369 except to edit src/config.h by hand to indicate which functions
372 Use mips-mips-riscos4.0 for RISCOS version 4.
373 Use mips-mips-bsd with the BSD world.
375 Note that the proper configuration names for DECstations are
376 mips-dec-ultrix and mips-dec-osf.
378 If you are compiling with GCC, then you must run fixincludes;
379 the alternative of using -traditional won't work because
380 the definition of SIGN_EXTEND_CHAR uses the keyword `signed'.
382 If the SYSV world is the default, then you probably need the following
383 line in etc/Makefile:
385 CFLAGS= -g -systype bsd43
387 Some operating systems on MIPS machines give SIGTRAP for division by
388 zero instead of the usual signals. The only real solution is to fix
389 the system to give a proper signal.
391 In the meantime, you can change init_data in data.c if you wish.
392 Change it to handle SIGTRAP as well as SIGFPE. But this will have a
393 great disadvantage: you will not be able to run Emacs under a
394 debugger. I think crashing on division by zero is a lesser problem.
396 dsg@mitre.org reported needing to use --x-libraries=/bsd43/usr/lib
397 on a riscos4bsd site. But it is not clear whether this is needed in
398 general or only because of quirks on a particular site.
400 NCR Intel system (i386-ncr-sysv4.2)
402 This system works in 19.31, but if you don't link it with GNU ld,
403 you may need to set LD_RUN_PATH at link time to specify where
404 to find the X libraries.
406 Prime EXL (i386-prime-sysv)
408 Minor changes merged in 19.1.
410 Siemens Nixdorf RM600 and RM400 (mips-siemens-sysv4)
412 Changes merged in 19.29. The version configured with
413 `--with-x' works without any modifications, but `--with-x-toolkit'
414 works only if the Athena library and the Toolkit library are linked
415 statically. For this, edit `src/Makefile' after the `configure' run
416 and modify the lines with `-lXaw' and `-lXt' as follows:
418 LIBW= /usr/lib/libXaw.a
419 LIBXT= $(LIBW) -lXmu /usr/lib/libXt.a $(LIBXTR6) -lXext
421 In addition, `--with-x-toolkit=motif' works only
422 if the Motif library and the Toolkit library are linked statically.
423 To do this, edit `src/Makefile' after the `configure' run
424 and modify the lines with `-lXm' and `-lXt' as follows:
426 LIBW= /usr/lib/libXm.a /usr/ccs/lib/libgen.a
427 LIBXT= $(LIBW) -lXmu /usr/lib/libXt.a $(LIBXTR6) -lXext
429 Sun 4 (sparc), Sun 386 (sparc-sun-solaris2.*,
430 i386-sun-solaris2.*, sparc*-*-linux-gnu)
432 To build a 32-bit Emacs (i.e. if you are having any sort of problem
433 bootstrapping a 64-bit version), you can use the Sun Studio compiler
434 and configure Emacs with:
435 env CC="cc -xarch=v7" CFLAGS='' ./configure # on SPARC systems
436 env CC="cc -xarch=386" CFLAGS='' ./configure # on x86 systems
437 On Solaris 2.10, it is also possible to use /usr/sfw/bin/gcc to build
438 a 32-bit version of Emacs. Just make sure you point ./configure to
441 env CC='/usr/sfw/bin/gcc -m32' ./configure
443 To build a 64-bit Emacs (with larger maximum buffer size and
444 including large file support) on a Solaris system which supports
445 64-bit executables, use the Sun compiler, configuring something like
446 this (see the cc documentation for information on 64-bit
449 env CC="cc -xarch=v9" CFLAGS='' ./configure # on SPARC systems
450 env CC="cc -xarch=amd64" CFLAGS='' ./configure # on x86 systems
452 As of version 2.95, GCC doesn't support the 64-bit ABI properly, but
455 Some versions of Solaris 8 have a bug in their XIM (X Input Method)
456 implementation which causes Emacs to dump core when one of several
457 frames is closed. To avoid this, either install patch 108773-12
458 (for Sparc) or 108874-12 (for x86), or configure Emacs with the
459 `--with-xim=no' switch (you can use Leim input methods instead).
461 On Solaris 2.7, building Emacs with WorkShop Compilers 5.0 98/12/15
462 C 5.0 failed, apparently with non-default CFLAGS, most probably due to
463 compiler bugs. Using Sun Solaris 2.7 Sun WorkShop 6 update 1 C
464 release was reported to work without problems. It worked OK on
465 another system with Solaris 8 using apparently the same 5.0 compiler
466 and the default CFLAGS.
468 Emacs 21.1 and 21.2 built with Sun's ProWorks PC3.0.1 compiler on
469 Intel/Solaris 8 was reported to abort and dump core during startup.
470 Using GCC or a newer SUN compiler (Sun WokShop 6 update 2 C 5.3
471 2001/05/15) solves the problem.
473 Emacs 20.5 and later work on SPARC GNU/Linux with the 32-bit ABI.
474 As of release 2.95, GCC doesn't work properly with the 64-bit ABI
475 (applicable on UltraSPARC), but that isn't the default mode.
477 Emacs 20.3 fails to build on Solaris 2.5 if you use GCC 2.7.2.3.
478 Installing GCC 2.8 fixes the problem.
480 19.32 works on Solaris 2.4 and 2.5. On Solaris 2.5
481 you may need one of these patches to prevent Emacs from crashing
483 103093-03: [README] SunOS 5.5: kernel patch (2140557 bytes)
484 102832-01: [README] OpenWindows 3.5: Xview Jumbo Patch (4181613 bytes)
485 103242-04: [README] SunOS 5.5: linker patch (595363 bytes)
487 There are reports that using SunSoft cc with -xO4 -xdepend produces
488 bad code for some part of Emacs.
490 Some people report that Emacs crashes immediately on startup when
491 used with a non-X terminal, but we think this is due to compiling
492 with GCC and failing to use GCC's "fixed" system header files.
494 Some Sun versions of X windows use the clipboard, not the selections,
495 for transferring text between clients. The Cut, Paste and Copy items
496 in the menu bar Edit menu work with the clipboard.
498 A user reported irreproducible segmentation faults when using 19.29
499 on Solaris 2.3 and 2.4 after compiling it with the Sun compiler.
500 The problem went away when GCC 2.7.0 was used instead. We do not know
501 whether anything in Emacs is partly to blame for this.
503 If you compile with Sun's ANSI compiler acc, you need additional options
504 when linking temacs, such as
505 /usr/lang/SC2.0.1/values-Xt.o -L/usr/lang/SC2.0.1/cg87 -L/usr/lang/SC2.0.1
506 (those should be added just before the libraries) and you need to
507 add -lansi just before -lc. The precise file names depend on the
508 compiler version, so we cannot easily arrange to supply them.
510 On Solaris 2, you need to install patch 100947-02 to fix a system bug.
511 Presumably this patch comes from Sun. You must alter the definition of
512 LD_SWITCH_SYSTEM if your X11 libraries are not in /usr/openwin/lib.
513 You must make sure that /usr/ucblib is not in your LD_LIBRARY_PATH.
515 On Solaris 2.2, with a multiprocessor SparcCenter 1000, Emacs 19.17 is
516 reported to hang sometimes if it exits while it has one or more
517 subprocesses (e.g. the `wakeup' subprocess used by `display-time').
518 Emacs and its subprocesses become zombies, and in their zombie state
519 slow down their host and disable rlogin and telnet. This is most
520 likely due to a bug in Solaris 2.2's multiprocessor support,
521 rather than an Emacs bug.
523 On Solaris, do not use /usr/ucb/cc. Use /opt/SUNWspro/bin/cc. Make
524 sure that /usr/ccs/bin and /opt/SUNWspro/bin are in your PATH before
525 /usr/ucb. (Most free software packages have the same requirement on
526 Solaris.) With this compiler, use `/opt/SUNWspro/bin/cc -E' as the
527 preprocessor. If this inserts extra whitespace into its output (see
528 the PROBLEMS file) then add the option `-Xs'.
530 If you have trouble using open-network-stream, get the distribution
531 of `bind' (the BSD name-server), build libresolv.a, and link Emacs
532 with -lresolv, by copying the #definition of LIBS_SYSTEM in
533 src/s/sunos4-1.h to src/config.h. This problem is due to obsolete
534 software in the nonshared standard library.
536 Note that Emacs on a Sun is not really as big as it looks.
537 As dumped, it includes around 200k of zeros between the
538 original text section and the original data section
539 (now remapped as part of the text). These are never
542 Tadpole 68K (m68k-tadpole-sysv)
544 Changes merged in 19.1.
546 You may need to edit Makefile to change the variables LIBDIR and
547 BINDIR from /usr/local to /usr/contrib.
549 To give movemail access to /usr/mail, you may need to execute
551 chmod 2755 etc/movemail; chgrp mail etc/movemail
553 Vaxen running Berkeley Unix (vax-dec-bsd4.1, vax-dec-bsd4.2, vax-dec-bsd4.3),
554 Ultrix (vax-dec-ultrix),
555 System V (vax-dec-sysv0, vax-dec-sysv2), or
560 See under Ultrix for problems using X windows on Ultrix (vax-dec-ultrix).
562 18.27 worked on System V rel 2 (vax-dec-sysv2).
564 18.36 worked on System V rel 0 (vax-dec-sysv0).
566 Richard Levitte <levitte@e.kth.se> distributes a set of patches to
567 Emacs 18.59 to make it work nicely under VMS. Emacs 19 probably
568 won't work very well, or even compile. Levitte is working on a
569 port, so these problems should be fixed in the near future.
572 Here are notes about some of the systems supported:
574 Linux (actually GNU/Linux)
576 Most of the complete systems which use the Linux kernel are close
577 enough to the GNU system to be considered variant GNU systems. We
578 call them "Linux-based GNU systems," or GNU/Linux for short.
580 It is not coincidence that many of the other components used with
581 Linux--including GNU Emacs--were developed specifically for the GNU
582 project. The GNU project was launched in 1984 to develop a free
583 complete Unix-like operating system. To reach this goal, we had to
584 develop whatever system components were not available as freely
585 redistributable software from some other source.
587 The GNU project wants users of GNU/Linux systems to be aware of how
588 these systems relate to the GNU project, because that will help
589 spread the GNU idea that software should be free--and thus encourage
590 people to write more free software. See the file LINUX-GNU in this
591 directory for more explanation.
595 See under "Intel 386".
599 For installation on MSDOS, see the file INSTALL (search for `MSDOG',
600 near the end of the file). See the "MS-DOS" chapter of the manual
601 for information about using Emacs on MSDOS.
605 If you are using MMDF instead of sendmail, you need to remove
606 /usr/lib/sendmail or modify lisp/paths.el before compiling.
607 lisp/paths.el (which is loaded during the build) will attempt to use
608 sendmail if it exists.
610 If you are using SMAIL, you need to define the macro
613 System V rel 4.0.3 and 4.0.4 (usg5.4)
615 Supported, including shared libraries for ELF, but ptys do not work
616 because TIOCGPGRP fails to work on ptys (but Dell 2.2 seems to have
617 fixed this). This failure is probably due to a misunderstanding of
618 the consequences of the POSIX spec: many system designers mistakenly
619 think that POSIX requires this feature to fail. This is untrue;
620 ptys are an extension, and POSIX says that extensions *when used*
621 may change the action of standard facilities in any fashion.
623 If you get compilation errors about wrong number of
624 arguments to getpgrp, define GETPGRP_NO_ARG.
626 The standard C preprocessor may generate xmakefile incorrectly. However,
627 /lib/cpp will work, so use `make CPP=/lib/cpp'. Standard cpp
628 seems to work OK under Dell 2.2.
630 Some versions 3 and earlier of V.4, on the Intel 386 and 860, had
631 problems in the X11 libraries. These prevent Emacs from working
632 with X. You can use Emacs with X provided your copy of X is based
633 on X11 release 4 or newer, or is Dell's 2.2 (which is a 4.0.3).
634 Unfortunately, the only way you can tell whether your X11 library is
635 new enough is to try compiling Emacs to use X. If emacs runs, your
636 X11 library is new enough.
638 In this context, GSV4 and GSV4i are alternate names for X11R4.
639 OL2.* is X11R3 based. OL3 is in between X11R3 and X11R4, and may or
640 may not work, depending on who made the Unix system. If the library
641 libXol is part of the X distribution, then you have X11R3 and Emacs
644 Most versions of V.4 support sockets. If `/usr/lib/libsocket.so'
645 exists, your system supports them. If yours does not, you must add
646 #undef HAVE_SOCKETS in config.h, after the inclusion of s-usg5-4.h.
647 (Any system that supports Internet should implement sockets.)
651 Richard Levitte <levitte@e.kth.se> distributes a set of patches to
652 Emacs 18.59 to make it work nicely under VMS. Emacs 19 probably
653 won't work very well, or even compile. Levitte is working on a
654 port, so these problems should be fixed in the near future.
656 Note that Emacs for VMS is usually distributed in a special VMS
657 distribution. See the file ../vms/VMSINSTALL for info on moving
658 Unix distributions to VMS, and other VMS-related topics.
660 Windows NT/95/98/ME/2000
662 For installation on all versions of the MS-Windows platform, see the
667 No special procedures should be needed to build a 64-bit Emacs. To
668 build a 32-bit Emacs, first ensure that the necessary 32-bit system
669 libraries and include files are installed. Then use:
671 env CC="gcc -m32" ./configure --build=i386-linux-gnu \
672 --x-libraries=/usr/X11R6/lib
674 (using the location of the 32-bit X libraries on your system).
