1 This is a list of the status of GNU Emacs on various machines and systems.
3 For each system and machine, we give the configuration name you should
4 pass to the `configure' script to prepare to build Emacs for that
7 The `configure' script uses the configuration name to decide which
8 machine and operating system description files `src/config.h' should
9 include. The machine description files are all in `src/m', and have
10 names similar to, but not identical to, the machine names used in
11 configuration names. The operating system files are all in `src/s',
12 and are named similarly. See the `configure' script if you need to
13 know which configuration names use which machine and operating system
16 If you add support for a new configuration, add a section to this
17 file, and then edit the `configure' script to tell it which
18 configuration name(s) should select your new machine description and
19 system description files.
22 Here are the configurations Emacs is intended to work with, with the
23 corresponding configuration names. You can postpend version numbers
24 to operating system names (i.e. sunos4.1) or architecture names (i.e.
25 hppa1.1). If you leave out the version number, the `configure' script
26 will configure Emacs for the latest version it knows about.
28 Acorn RISCiX (arm-acorn-riscix1.2)
30 Emacs 19.29 has changes that ought to support RISCiX 1.2.
32 Due to a bug in the RISCiX C compiler (3.4.5), emacs must
33 be built with gcc (versions 2.5.8 onwards).
35 In addition, you will need GNU sed and GNU make, as the RISCiX release
36 versions of these utilities cannot cope with building emacs-19!
38 GNU sed should be configured with:
40 env 'DEFS=-Dgetopt=gnu_getopt -Dopterr=gnu_opterr -Doptind=gnu_optind \
41 -Doptarg=gnu_optarg' ./configure
43 GNU make (3.72+) should be configured with:
45 env 'CFLAGS=-Dgetopt=gnu_getopt -Dopterr=gnu_opterr -Doptind=gnu_optind \
46 -Doptarg=gnu_optarg' ./configure
48 Emacs may be configured to use the X toolkit, by adding --with-x-toolkit
49 to the configure command. If you do this, you will need to edit the line
50 in src/Makefile which defines LIBW (about line 59) to read:
54 This ensures that the non-shared widget library is used.
56 It is unlikely that this version of emacs will work with RISCiX 1.1.
58 Alliant (fx80-alliant-bsd):
60 18.52 worked on system version 4. Previous Emacs versions were
61 known to work on previous system versions.
63 If you are using older versions of their operating system, you may
64 need to edit `src/config.h' to use `m/alliant1.h' (on version 1) or
65 `m/alliant.h' (on versions 2 and 3).
67 Alliant FX/2800 (i860-alliant-bsd)
69 Known to work with 19.26 and OS version 2.2, compiler version 1.3.
71 Alpha (DEC) running OSF/1 or GNU/Linux (alpha-dec-osf1, alpha-dec-linux-gnu)
73 For OSF/1 (aka Digital Unix) version 4.0, update 386,
74 it is reported that you need to run configure this way:
76 configure --x-includes=/usr/include --x-libraries=/usr/shlib
78 For 4.0 revision 564, and 4.0A and 4.0B, Emacs 20 seems to work
79 with no special configuration options. However, if you use GCC as
80 your compiler, you will need version 2.8.1 or later, as older
81 versions fail to build with a message "Invalid dimension for the
84 Note that the X11 libraries on GNU/Linux systems for the Alpha are
85 said to have bugs that prevent Emacs from working with X (as of
86 November 1995). Recent releases work (July 2000).
88 Altos 3068 (m68k-altos-sysv)
90 18.52 was said to work, provided you don't compile unexec.c with -O.
92 Amdahl UTS (580-amdahl-sysv)
94 Small changes for 18.38 were merged in 18.39. It is mostly
95 working, but at last report a bug sometimes causes Emacs to
96 grab very large amounts of memory. No fix or explanation
97 has yet been reported. It may be possible to find this bug
98 if you find which Emacs command it happens within and then
99 run that command with a breakpoint set at malloc.
101 The 5.2u370 compiler is so brain damaged that it is not
102 even worth trying to use it. Success was obtained with the
103 uts native C compiler on uts version 5.2.5.
105 Apple PowerPC Macintosh running GNU/Linux
107 There are special considerations for a variety of this system which
108 is known as the ``Yellow Dog [GNU/]Linux'': Emacs may crash during
109 dumping. To solve this, edit the header file src/m/macppc.h in the
110 Emacs distribution, and remove the "#if 0" and "#endif" directives
111 which surround the following block near the end of the file:
113 #if 0 /* This breaks things on PPC GNU/Linux ecept for Yellowdog,
114 even with identical GCC, as, ld. Let's take it out until we
115 know what's really going on here. */
116 /* GCC 2.95 and newer on GNU/Linux PPC changed the load address to
118 #if defined __linux__
119 #if __GNUC__ > 2 || (__GNUC__ == 2 && __GNUC_MINOR__ >= 95)
120 #define DATA_SEG_BITS 0x10000000
125 After that, reconfigure and rebuild Emacs. It should now build
128 Apollo running X Windows (m68k-apollo-bsd)
130 Apollo version now supports dumping. It has been tested on SR10.3 and
131 SR10.4. It certainly requires at least SR10.0, and maybe SR10.2. Be sure
132 to build in the BSD environment.
134 By default, everything is compiled with the switch "-W0,-opt,2". Don't try
135 to change this to full optimization (-O). The full optimizer (in Domain CC
136 6.7, 6.8 and 6.9) generates some bad code in several modules which causes
137 the emacs window, under X, to be refreshed with each keystroke.
139 The configuration stuff should work for the most part. However, some Domain
140 installations may have to edit src/Makefile manually after it is created.
141 There are too many versions of both cc and X to automate this easily.
143 In `lib-src/Makefile', emacsclient and emacsserver compile and work fine
144 under CC 6.9. They now probably work under other versions of the compiler,
147 The Apollo Domain CC compiler will issue quite a few warning messages,
148 mostly complaining about incompatible pointers. In general, these are
149 harmless and can be ignored. If you discover otherwise, please submit a bug
150 report identifying the problem in detail.
152 When you try to dump emacs, you may get the message ".rwdi section needs
153 relocation." This means you are linking with some code that has compressed
154 data sections. In some cases this comes from linking with X libraries. Try
155 using shared X libraries instead. With some versions of Domain/OS this is
156 as simple as removing the "-lX11" from the LIBX line in src/Makefile.
158 When running the configure script, use the configuration name
159 "m68k-apollo-bsd". You will also need to use the "-with-gcc=no" and
160 "-with-x" options. Depending upon your site configuration, you may have to
161 use other configure options, as well. Examine the INSTALL file for other
164 Check out the file 'lisp/x-apollo.el'. To use it, add
168 to your .emacs file. It provides useful default Apollo function key
171 AT&T 3b2, 3b5, 3b15, 3b20 (we32k-att-sysv)
173 Emacs will probably not work with certain kernel constants too small.
175 In param.h CDLIMIT should be at least (1L << 12) in order to allow
176 processes to write up to 2 Mbyte files. This parameter is configurable
177 by normal means in /etc/master.d/kernel; examine that file for the
178 symbol CDLIMIT or ULIMIT, and raise it by several powers of 2. Then
179 do normal kernel rebuild things via "cd /boot; mkboot -k KERNEL" and so
182 In seg.h NSEGP and STACKSEG should be at least 16 and 4 respectively
183 to allow processes with total size of up to 2Mbytes.
184 However, I'm told it is unlikely this would fail to be true.
186 The MAXMEM may also prevent Emacs from running. The file
187 3B-MAXMEM in this directory explains how to increase MAXMEM.
189 On some of these machines, you may need to define IN_SCCS_ID
190 in config.h to make Emacs work. Supposedly you can tell whether
191 this is necessary by checking something in /usr/include/sys/time.h;
192 we do not know precisely what.
194 AT&T 7300 or 3b1 (m68k-att-sysv)
196 18.52 worked. If you have strange troubles with dumping
197 Emacs, delete the last few lines from `src/m/7300.h' and recompile.
198 These lines are supposed to produce a sharable executable.
200 `src/m/7300.h' defines SHORTNAMES because operating system versions
201 older than 3.5 did not support long symbol names. Version 3.5 does
202 support them, so you can remove the #define SHORTNAMES in that
205 Bull DPX/2 models 2nn or 3nn (m68k-bull-sysv3)
207 Minor fixes merged into 19.19, which should work with CC or GCC.
209 You should compile with all the POSIX stuff: undef _SYSV and define
210 _POSIX_SOURCE, _XOPEN_SOURCE and _BULL_SOURCE.
212 On bos2.00.45 there is a bug that makes the F_SETOWN fcntl
213 call enters in an infinite loop. F_SETOWN_BUG has been defined to avoid
216 Bull DPX/20 (rs6000-bull-bosx)
220 Bull sps7 (m68k-bull-sysv2)
222 Changes partially merged in version 19, but some fixes are probably required.
228 Celerity (celerity-celerity-bsd4.2)
230 Version 18.49 worked. This configuration name is a hack, because we
231 don't know the processor used by Celerities. If someone
232 who uses a Celerity could get in touch with us, we can teach
233 config.sub a better name for the configuration.
235 Clipper (clipper-???)
237 Version 19 has support for some brand of clipper system. If you
238 have successfully built Emacs 19 on some sort of clipper system, let
239 us know so we can flesh out this entry.
241 Note that the Orion 105 is also a clipper, but some system-related
242 parameters are different.
244 Convex (c1-convex-bsd, c2-convex-bsd, c32-convex-bsd, c34-convex-bsd,
247 Support updated and residual bugs fixed in 19.26.
249 Cubix QBx/386 (i386-cubix-sysv)
251 Changes merged in 19.1. Systems before 2/A/0 may fail to compile etags.c
252 due to a compiler bug.
254 Cydra 5 (cydra-cydrome-sysv)
256 18.51 worked in one version of their operating system but stopped
257 working in a newer version. This has not been fixed.
259 Data General Aviion (m88k-dg-dgux)
261 19.23 works; however, the GCC provided with DGUX 5.4R3.00 fails to
262 compile src/emacs.c. GCC 2.5.8 does work.
263 The 19.26 pretest was reported to work; no word on which compiler.
264 System versions other than DGUX 5.4R3.00 have not been tested.
266 DGUX 5.4R3.10 works with 19.29 and 19.30.
268 DGUX R4.11 contains changes to the stdio internals and it doesn't work
269 with versions before 20.2 without patches. 20.2 works in interactive
270 mode but usually fails in batch mode. The problem is that using
271 stderr in the dumped emacs usually leads to a segmentation fault.
272 Only m88k has been tested.
274 DECstation (mips-dec-ultrix or mips-dec-osf)
276 This machine is the older Mips-based DECstation.
277 Emacs should now work on the Alpha CPU.
279 19.25 works on Ultrix 4.2. The 19.26 pretest was reported to work
280 on Ultrix 4.2a and on 4.4.
282 One user reported 19.25 did not work at all with --with-x-toolkit
283 using X11R5 patch level 10, but worked ok with X11R5 pl26.
285 See under Ultrix for problems using X windows on Ultrix.
286 Note that this is a MIPS machine.
288 For Ultrix versions 4.1 or earlier, you may need to define
289 SYSTEM_MALLOC in `src/m/pmax.h', because XvmsAlloc.o in libX11.a seems
290 to insist on defining malloc itself.
292 For Ultrix versions prior to 4.0, you may need to delete
293 the definition of START_FILES from `src/m/pmax.h'.
295 Motorola Delta 147 (m68k-motorola-sysv)
297 The EMacs 19.26 pretest was reported to work.
299 Motorola Delta boxes running System V/68 release 3.
300 Tested on 147 board with SVR3V7, no X and gcc.
301 Tested on 167 board with SVR3V7, no X, cc, gnucc and gcc.
302 Reports say it works with X too.
304 The installation script chooses the compiler itself. gnucc is
307 Motorola Delta 187 (m88k-motorola-sysv,
308 m88k-motorola-sysvr4, or
309 m88k-motorola-m88kbcs)
311 The 19.26 pretest was reported to run on SVR3. However, if you
312 use --with-x-toolkit on svr3, you will have problems compiling some
313 files because time.h and sys/time.h get included twice.
314 One fix is to edit those files to protect against multiple inclusion.
316 As of version 19.13, Emacs was reported to run under SYSVr3 and SYSVr4.
318 Dual running System V (m68k-dual-sysv)
320 As of 17.46, this worked except for a few changes
323 Dual running Uniplus (m68k-dual-uniplus)
327 Elxsi 6400 (elxsi-elxsi-sysv)
329 Changes for 12.0 release are in 19.1.
330 Dumping should work now.
332 Encore machine (ns16k-encore-bsd)
334 This machine bizarrely uses 4.2BSD modified to use the COFF format
335 for object files. Works (as of 18.40). For the APC processor you
336 must enable two lines at the end of `src/s/umax.h', which are commented
337 out in the file as distributed.
339 WARNING: If you compile Emacs with the "-O" compiler switch, you
340 must also use the "-q enter_exits" switch so that all functions have
341 stack frames. Otherwise routines that call `alloca' all lose.
343 A kernel bug in some system versions causes input characters to be lost
346 Fujitsu DS/90 (sparc-fujitsu-sysv4)
348 Changes merged in 20.3.
350 GEC 63 (local-gec63-usg5.2)
352 Changes are partially merged in version 18, but certainly require
353 more work. Let us know if you get this working, and we'll give it a
354 real configuration name.
356 Gould Power Node (pn-gould-bsd4.2 or pn-gould-bsd4.3)
358 18.36 worked on versions 1.2 and 2.0 of the operating system.
360 On UTX/32 2.0, use pn-gould-bsd4.3.
362 On UTX/32 1.2 and UTX/32S 1.0, use pn-gould-bsd4.2 and note that
363 compiling `lib-src/sorted-doc' tickles a compiler bug: remove the -g
364 flag to cc in the makefile.
366 UTX/32 1.3 has a bug in the bcopy library routine. Fix it by
367 #undef BSTRING in `src/m/gould.h'.
369 Version 19 incorporates support for releases 2.1 and later of UTX/32.
370 A site running a pre-release of 2.1 should #define RELEASE2_1 in config.h.
372 Gould NP1 (np1-gould-bsd)
374 Version 19 supposedly works.
376 Harris Night Hawk (m68k-harris-cxux or m88k-harris-cxux)
378 This port was added in 19.23. The configuration actually tested was
379 a Night Hawk 4800 running CX/UX 7.0.
381 If you have GCC ported and want to build with it, you probably need to
382 change things (like compiler switches) defined in the s/cxux.h file.
384 If you have X11R6 installed in /usr/lib, configure will fail to find
385 it and may find X11R5 instead. To work around this problem, use
386 --x-libraries=/usr/lib when you run configure.
388 With CX/UX 7.0 and later releases, you need to build after setting the
389 SDE_TARGET environment variable to COFF (a port using ELF and shared
390 libraries has not yet been done).
392 Harris Power PC (powerpc-harris-powerunix)
394 Patches have been merged in 19.31.
396 Honeywell XPS100 (xps100-honeywell-sysv)
398 Config file added in version 19.
400 Hewlett-Packard 9000 series 200 or 300 (m68k-hp-bsd or m68k-hp-hpux
403 These machines are 68000-series CPUs running HP/UX
404 (a derivative of sysV with some BSD features) or BSD 4.3 ported by Utah.
405 The operating system suffix determines which system Emacs is built for.
407 Series 200 HPUX runs Emacs only if it has the "HP/UX upgrade".
409 Version 19 works under BSD. The 19.26 pretest was reported
410 to work on HPUX 9. 19.31 works on HPUX 10.01, but there are
411 some problems on 10.10 which have not been resolved. Emacs 19.34
412 works on HPUX 10.20 provided you compile with GCC; with the HP C
413 compiler, subprocess commands do not work.
415 On HPUX 9, Emacs sometimes crashes with SIGBUS or SIGSEGV after you
416 delete a frame. We think this is due to a bug in the X libraries
417 provided by HP. With the alternative X libraries in
418 /usr/contrib/mitX11R5/lib, the problem does not happen.
420 If you are running HP/UX release 8.0 or later, you need the optional
421 "C/ANSI C" software in order to build Emacs (older releases of HP/UX
422 do not require any special software). If the file "/etc/filesets/C"
423 exists on your machine, you have this software, otherwise you do not.
425 Note that HP has used two incompatible assembler syntaxes,
426 and has recently changed the format of C function frames.
427 `src/crt0.c' and `src/alloca.s' have been conditionalised for the new
428 assembler and new function-entry sequence. You may need to define
429 OLD_HP_ASSEMBLER if you are using an older hpux version. If you
430 have an official (bought from HP) series 300 machine you have
431 the new assembler. Kernels that are 5.+ or later have new
432 assembler. A Series 200 that has been upgraded to a 68010
433 processor and a 5.+ kernel has the new compiler.
435 Define C_SWITCH_MACHINE to be +X to make a version of Emacs that
436 runs on both 68010 and 68020 based HP/UX's.
438 Define HPUX_68010 if you are using the new assembler, for
439 a system that has a 68010 without a 68881. This is to say,
440 a s200 (upgraded) or s310.
442 Define the symbol HPUX_NET if you have the optional network features
443 that include the `netunam' system call. This is referred to as
444 Network Services (NS/9000) in HP literature.
446 HP 9000 series 500: not supported.
448 The series 500 has a seriously incompatible memory architecture
449 which relocates data in memory during execution of a program,
450 and support for it would be difficult to implement.
452 HP 9000 series 700 or 800 (Spectrum) (hppa1.0-hp-hpux or hppa1.1-hp-hpux
453 or ...hpux9shr, or ...-nextstep)
455 Use hppa1.1 for the 700 series and hppa1.0 for the 800
456 series machines. (Emacs may not actually care which one you use.)
458 Support for NextSTEP was added in 19.31.
460 Emacs 20 may work on HPUX 10. You need patch PHSS_6202 to install
461 the Xaw and Xmu libraries. On HPUX 10.20 you may need to compile with GCC;
462 when Emacs was compiled with HP's C compiler, HP92453-01 A.10.32.03,
463 the subprocess features failed to work.
465 19.26 is believed to work on HPUX 9 provided you compile with GCC.
466 As of version 19.16, Emacs was reported to build (using GCC) and run
467 on HP 9000/700 series machines running HP/UX versions 8.07 and 9.01.
468 The HP compiler is known to fail on some versions if you use +O3,
469 but it may work with lower optimization levels.
471 Use hppa1.1-hp-hpux9shr to use shared libraries on HPUX version 9.
472 You may need to create the X libraries libXaw.a and libXmu.a from
473 the MIT X distribute, and you may need to edit src/Makefile's
474 definition of LIBXT to look like this:
476 LIBXT= $(LIBW) -lXmu -lXt $(LIBXTR6) -lXext
478 Some people report trouble using the GNU memory allocator under
479 HP/UX version 9. The problems often manifest as lots of ^@'s in the
482 We are told that these problems go away if you obtain the latest
483 patches for the HP/UX C compiler. James J Dempsey
484 <jjd@spserv.bbn.com> says that this set of versions works for him:
486 HP92453-01 A.09.28 HP C Compiler
488 HP92453-01 A.09.28 HP C Compiler
489 HP-UX SLLIC/OPTIMIZER HP-UX.09.00.23 02/18/93
490 Ucode Code Generator - HP-UX.09.00.23.5 (patch) 2/18/93
492 For 700 series machines, the HP-UX patch needed is known as
493 PHSS_2653. (Perhaps for 800 series machines as well; we don't
494 know.) If you are on the Internet, you should be able to obtain
495 this patch by using telnet to access the machine
496 support.mayfield.hp.com and logging in as "hpslreg" and following
497 the instructions there. Or you may be able to use this
500 HP Patch Server: http://support.mayfield.hp.com/patches/html/patches.html
501 HP Support Line: http://support.mayfield.hp.com
503 Please do not ask FSF for further support on this. If you have any
504 trouble obtaining the patch, contact HP Software Support.
506 If your buffer fills up with nulls (^@) at some point, it could well
507 be that problem. That problem does not happen when people use GCC
508 to compile Emacs. On the other hand, the HP compiler version 9.34
509 was reported to work for the 19.26 pretest. 9.65 was also reported to work.
511 If you turn on the DSUSP character (delayed suspend),
512 Emacs 19.26 does not know how to turn it off on HPUX.
513 You need to turn it off manually.
515 If you are running HP/UX release 8.0 or later, you need the optional
516 "C/ANSI C" software in order to build Emacs (older releases of HP/UX
517 do not require any special software). If the file "/etc/filesets/C"
518 exists on your machine, you have this software, otherwise you do not.
520 High Level Hardware Orion (orion-highlevel-bsd)
522 This is the original microprogrammed hardware.
523 Machine description file ought to work.
525 High Level Hardware Orion 1/05 (clipper-highlevel-bsd)
527 Changes merged in 18.52. This is the one with the Clipper cpu.
528 Note that systems which lack NFS need LOAD_AVE_TYPE changed to `double'.
530 C compiler has a bug; it loops compiling eval.c.
531 Compile it by hand without optimization.
533 HITACHI SR2001/SR2201 series (hppa1.1-hitachi-hiuxwe2)
535 These machines are based on PA architecture running HI-UX/MPP
536 (based on OSF1. `MPP' stands for `Massively Parallel Processor').
538 Emacs 19.34 is believed to work; its pretest was tested
539 both on SR2001 (output of `uname -rv' is `00-01-BB 0') and
542 Emacs 20.7 was reported to build on a system whose `uname -rs'
543 output is `HI-UX/MPP 03-04'.
545 The machine description file is `src/m/sr2k.h' is based on
546 `src/m/hp800.h'. The system description file is `src/s/hiuxwe2.h'
547 based on `src/s/osf1.h'. Note that this system doesn't use COFF.
549 IBM PS/2 (i386-ibm-aix1.1 or i386-ibm-aix1.2)
551 Changes merged in version 19. You may need to copy
552 /usr/lib/samples/hft/hftctl.c to the Emacs src directory.
554 i386-ibm-aix1.1 may not work with certain new X window managers, and
557 IBM RS/6000 (rs6000-ibm-aix*)
559 Emacs 19.26 is believed to work; its pretest was tested.
561 Compiling with the system's `cc' and CFLAGS containing `-O5' might
562 fail because libXbsd isn't found. This is a compiler bug;
563 re-configure Emacs so that it isn't compiled with `-O5'.
565 On AIX 4.3.x and 4.4, compiling with /bin/c89 fails because it
566 treats certain warnings as errors. Use `cc' instead.
568 At last report, Emacs didn't run well on terminals. Informed
569 persons say that the tty VMIN and VTIME settings have been
570 corrupted; if you have a fix, please send it to us.
572 Compiling with -O using the IBM compiler has been known
573 to make Emacs work incorrectly. It's reported that on
574 AIX 3.2.5 with an IBM compiler earlier than 1.03.00.14,
575 cc -O fails for some files. You need to install any
576 PTF containing APAR #IX42810 to bring the compiler to
577 the 1.03.00.14 level to allow optimized compiles.
579 There are reports that IBM compiler versions earlier than 1.03.00.02
580 fail even without -O. However, another report said that compiler
581 version 1.02.01.00 did work, on AIX 3.2.4, with Emacs 19.31.
583 As of 19.11, if you strip the Emacs executable, it ceases to work.
585 If you are using AIX 3.2.3, you may get a core dump when loading
586 ange-ftp. You may be able to fix the problem by defining LIBS_TERMCAP
587 as -ltermcap -lcurses. Please tell us if this fails to work.
589 If anyone can fix the above problems, or confirm that they don't happen
590 with certain versions of various programs, we would appreciate it.
592 IBM RT/PC (romp-ibm-bsd or romp-ibm-aix)
594 Use romp-ibm-bsd for the 4.2-like system and romp-ibm-aix for AIX.
595 19.22 is reported to work under bsd. We don't know about AIX.
597 On BSD, if you have trouble, try compiling with a different compiler.
599 On AIX, the file /usr/lib/samples/hft/hftctl.c must be compiled into
600 hftctl.o, with this result left in the src directory (hftctl.c is
601 part of the standard AIX distribution).
603 window.c must not be compiled with -O on AIX.
605 IBM System/390 running GNU/Linux (s390-*-linux-gnu)
607 As of Emacs 21.2, a 31-bit only version is supported on this
610 Integrated Solutions `Optimum V' (m68k-isi-bsd4.2 or -bsd4.3)
612 18.52 said to work on some sort of ISI machine.
613 Version 18.45 worked (running on a Optimum V (VME bus, 68020)
614 BSD 4.2 (3.05e) system). 18.42 is reported to work on
615 a Qbus 68010 system. Has not been tried on `WorkStation' `Cluster
616 Compute Node' `Cluster WorkStation' or `Server Node' (Love the
619 Compilation with -O is rumored to break something.
621 On recent system versions, you may need to undefine the macro UMAX
622 in `lib-src/loadst.c' and `src/getpagesize.h'. They stupidly defined this
623 in a system header file, which confuses Emacs (which thinks that UMAX
624 indicates the Umax operating system).
626 Intel 386 (i386-*-isc, i386-*-esix, i386-*-bsdi2,
627 i386-*-xenix, i386-*-freebsd, i386-*-linux-gnu,
628 i386-*-sol2.4, i386-*-sysv3, i386-intsys-sysv,
629 i386-*-sysv4, i386-*-sysv4.2,
630 i386-*-sysv5.3, i386-*-bsd4.2,
631 i386-*-sco3.2v4, i386-*-bsd386, i386-*-386bsd,
632 i386-*-msdos, i386-*-windowsnt.
633 i386... can be replaced with i486... or i586...)
635 In the above configurations, * means that the manufacturer's name
636 you specify does not matter, and you can use any name you like
637 (but it should not contain any dashes or stars).
639 When using the ISC configurations, be sure to specify the isc
640 version number - for example, if you're running ISC 3.0, use
641 i386-unknown-isc3.0 as your configuration name.
642 Use i386-*-esix for Esix; Emacs runs as of version 19.6.
643 Use i386-*-linux-gnu for GNU/Linux systems; Emacs runs as of version 19.26.
644 Use i386-intsys-sysv for Integrated Solutions 386 machines.
645 It may also be correct for Microport systems.
646 Use i386-*-sco3.2v4 for SCO 3.2v4; Emacs runs as of version 19.26.
648 On GNU/Linux systems, Emacs 19.23 was said to work properly with libc
649 version 4.5.21, but not with 4.5.19. If your system uses QMAGIC
650 for the executable format, you must edit config.h to define LINUX_QMAGIC.
652 On GNU/Linux, configure may fail to put these definitions in config.h:
654 #define HAVE_GETTIMEOFDAY
657 #define HAVE_XSCREENNUMBEROFSCREEN
659 To work around the problem, add those definitions by hand.
660 It is possible that this problem happens only with X11R6.
661 Newer system versions have fixed it.
663 The 19.26 pretest was reported to work on SVR4.3 and on Freebsd.
665 19.29 is reported to crash when using Motif on Solaris 2.5.
666 The reasons are not yet known.
668 Use i386-*-bsdiN for BSDI BSD/OS version N; Emacs runs as of version 19.23.
669 In some system versions, `make' is broken; use GNU make instead.
670 Shell bugs in version 1.0 of BSD/OS cause configure
671 to do the wrong thing with --with-x-toolkit; the workaround is to edit
672 configure to run another shell such as bash.
674 For System V release 3, use i386-*-sysv3.
675 For System V release 4, use i386-*-sysv4.
676 For System V release 4.2, use i386-*-sysv4.2.
678 If you are using Xenix, see notes at end under Xenix.
679 If you are using Esix, see notes at end under Esix.
680 If you are using SCO Unix, see notes at end under SCO.
682 On 386bsd, NetBSD and FreeBSD, at one time, it was necessary to use
683 GNU make, not the system's make. Assuming it's installed as gmake,
684 do `gmake install MAKE=gmake'. However, more recently it is
685 reported that using the system Make on NetBSD 1.3.1 works ok.
687 If you are using System V release 4.2, you may find that `cc -E'
688 puts spurious spaces in `src/xmakefile'. If that happens,
689 specify CPP=/lib/cpp as an option when you run make.
690 There is no problem if you compile with GCC.
692 Note that use of Linux with GCC 2.4 and the DLL 4.4 libraries
693 requires the experimental "net 2" network patches (no relation to
694 Berkeley Net 2). There is a report that (some version of) Linux
695 requires including `/usr/src/linux/include/linux' in buffer.c
696 but no coherent explanation of why that might be so. If it is so,
697 in current versions of Linux, something else should probably be changed.
699 Some sysV.3 systems seem to have bugs in `opendir';
700 for them, alter `config.h' to define NONSYSTEM_DIR_LIBRARY
701 and undefine SYSV_SYSTEM_DIR.
703 If you use optimization on V.3, you may need the option -W2,'-y 0'
704 to prevent certain faulty optimization.
706 On 386/ix, to link with shared libraries, add #define USG_SHARED_LIBRARIES
709 On SCO, there are problems in regexp matching when Emacs is compiled
710 with the system compiler. The compiler version is "Microsoft C
711 version 6", SCO 4.2.0h Dev Sys Maintenance Supplement 01/06/93;
712 Quick C Compiler Version 1.00.46 (Beta). The solution is to compile
715 On ISC systems (2.02 and more recent), don't try to use the versions
716 of X that come with the system; use XFree86 instead.
718 There is no consistency in the handling of certain system header files
721 Some versions have sys/sioctl.h, and require it in sysdep.c.
722 But some versions do not have sys/sioctl.h.
723 For a given version of the system, this may depend on whether you have
724 X Windows or TCP/IP. Define or undefine NO_SIOCTL_H in config.h
725 according to whether you have the file.
727 Likewise, some versions have been known to need sys/ttold.h, sys/stream.h,
728 and sys/ptem.h included in sysdep.c. If your system has these files,
729 try defining NEED_PTEM_H in config.h if you have trouble without it.
731 You may find that adding -I/usr/X/include or -I/usr/netinclude or both
732 to CFLAGS avoids compilation errors on certain systems.
734 Some versions convince sysdep.c to try to use `struct tchars'
735 but define `struct tc' instead; add `#define tchars tc'
736 to config.h to solve this problem.
738 Iris 2500 and Iris 2500 Turbo (m68k-sgi-iris3.5 or m68k-sgi-iris3.6)
740 Version 18 was said to work; use m68k-sgi-iris3.5 for system version 2.5
741 and m68k-sgi-iris3.6 for system version 3.6.
742 Note that the 3030 is the same as the Iris 2500 Turbo.
744 Iris 4D (mips-sgi-irix[456].*)
746 You can build a 64-bit executable (with larger maximum buffer size)
747 on Irix 6.5 by specifying the 64-bit ABI using the `-64' compiler
748 flag or otherwise (see cc(1)). This may work on earlier Irix 6
749 systems if you edit src/s/irix6-0.h following irix6-5.h.
751 If compiling with GCC on Irix 6 yields an error "conflicting types
752 for `initstate'", install GCC 2.95 or a newer version, and this
753 problem should go away. It is possible that this problem results
754 from upgrading the operating system without reinstalling GCC; so you
755 could also try reinstalling the same version of GCC, and telling us
756 whether that fixes the problem.
758 The 19.26 pretest was reported to work on IRIX 4.0.5 and 5.2.
759 19.23 was reported to work on IRIX 5.2, but you may need to install
760 the "compiler_dev.hdr.internal" subsystem in order to compile unexelfsgi.c.
761 19.22 was known to work on all Silicon Graphics machines running
762 IRIX 4.0.5 or IRIX 5.1.
764 Compiling with -O using IRIX compilers prior to 3.10.1 may not work.
765 Don't use -O or use GCC instead.
767 Most IRIX 3.3 systems do not have an ANSI C compiler, but a few do.
768 Compile Emacs 18 with the -cckr switch on these machines.
770 There is a bug in IRIX 3.3 that can sometimes leave ptys owned by root
771 with a permission of 622. This causes malfunctions in use of
772 subprocesses of Emacs. Irix versions 4.0 and later with GNU Emacs
773 versions 18.59 and later fix this bug.
775 Masscomp (m68k-masscomp-rtu)
777 18.36 worked on a 5500DP running RTU v3.1a and compiler version 3.2
778 with minor fixes that are included in 18.37. However, bizarre behavior
779 was reported for 18.36 on a Masscomp (model and version unknown but probably
780 a 68020 system). The report sounds like a compiler bug.
782 A compiler bug affecting statements like
783 unsigned char k; unsigned char *p;... x = p[k];
784 has been reported for "C version 1.2 under RTU 3.1". We do not wish
785 to take the time to install the numerous workarounds required to
786 compensate for this bug.
788 For RTU version 3.1, define FIRST_PTY_LETTER to be 'p' in `src/s/rtu.h'
789 (or #undef and redefine it in config.h) so that ptys will be used.
791 GNU Emacs is said to have no chance of compiling on RTU versions
794 Megatest (m68k-megatest-bsd)
796 Emacs 15 worked; do not have any reports about Emacs 16 or 17
797 but any new bugs are probably not difficult.
799 Mips (mips-mips-riscos, mips-mips-riscos4.0, or mips-mips-bsd)
801 The C compiler on Riscos 4.51 dumps core trying to optimize
802 parts of Emacs. Try without optimization or try GCC.
804 Meanwhile, the linker on that system returns success even if
805 there are undefined symbols; as a result, configure gets the
806 wrong answers to various questions. No work-around is known
807 except to edit src/config.h by hand to indicate which functions
810 Use mips-mips-riscos4.0 for RISCOS version 4.
811 Use mips-mips-bsd with the BSD world.
813 Note that the proper configuration names for DECstations are
814 mips-dec-ultrix and mips-dec-osf.
816 If you are compiling with GCC, then you must run fixincludes;
817 the alternative of using -traditional won't work because
818 the definition of SIGN_EXTEND_CHAR uses the keyword `signed'.
820 If the SYSV world is the default, then you probably need the following
821 line in etc/Makefile:
823 CFLAGS= -g -systype bsd43
825 Some operating systems on MIPS machines give SIGTRAP for division by
826 zero instead of the usual signals. The only real solution is to fix
827 the system to give a proper signal.
829 In the meantime, you can change init_data in data.c if you wish.
830 Change it to handle SIGTRAP as well as SIGFPE. But this will have a
831 great disadvantage: you will not be able to run Emacs under a
832 debugger. I think crashing on division by zero is a lesser problem.
834 dsg@mitre.org reported needing to use --x-libraries=/bsd43/usr/lib
835 on a riscos4bsd site. But it is not clear whether this is needed in
836 general or only because of quirks on a particular site.
838 National Semiconductor 32000 (ns32k-ns-genix)
840 This is for a complete machine from National Semiconductor,
841 running Genix. Changes merged in version 19.
843 NCR Tower 32 (m68k-ncr-sysv2 or m68k-ncr-sysv3)
845 If you are running System V release 2, use m68k-ncr-sysv2.
846 If you are running System V release 3, use m68k-ncr-sysv3.
848 These both worked as of 18.56. If you change `src/ymakefile' so that
849 CFLAGS includes C_OPTIMIZE_SWITCH rather than C_DEBUG_SWITCH, check
850 out the comments in `src/m/tower32.h' (for System V release 2) or
851 `src/m/tower32v3.h' (for System V release 3) about this.
853 There is a report that compilation with -O did not work with 18.54
854 under System V release 2.
856 NCR Intel system (i386-ncr-sysv4.2)
858 This system works in 19.31, but if you don't link it with GNU ld,
859 you may need to set LD_RUN_PATH at link time to specify where
860 to find the X libraries.
862 NEC EWS4800 (mips-nec-sysv4)
864 This system works in 20.4, but you should use the compiler
865 /usr/abiccs/bin/cc (MIPS ABI MODE).
867 NeXT (m68k-next-nextstep)
869 Emacs 19 has not been tested extensively yet, but it seems to work
870 in a NeXTStep 3.0 terminal window, and under the X server called
871 co-Xist. You may need to specify -traditional when src/Makefile
874 NeXT users might want to implement direct operation with NeXTStep,
875 but from the point of view of the GNU project, that is a
878 Thanks to Thorsten Ohl for working on the NeXT port of Emacs 19.
880 Nixdorf Targon 31 (m68k-nixdorf-sysv)
882 Machine description file for version 17 is included in 18
883 but whether it works is not known.
884 `src/unexec.c' bombs if compiled with -O.
885 Note that the "Targon 35" is really a Pyramid.
887 Nu (TI or LMI) (m68k-nu-sysv)
889 Version 18 is believed to work.
891 Paragon OSF/1 (i860-intel-osf1)
893 Changes merged in 19.29.
895 There is a bug in OSF/1 make which claims there is a syntax error
896 in the src/xmakefile. You can successfully build emacs with:
900 Plexus (m68k-plexus-sysv)
904 Pmax (DEC Mips) (mips-dec-ultrix or mips-dec-osf1)
906 See under DECstation, above.
908 Prime EXL (i386-prime-sysv)
910 Minor changes merged in 19.1.
912 Pyramid (pyramid-pyramid-bsd)
914 The 19.26 pretest was observed to work on OSx 5.0, but it is necessary
915 to edit gmalloc.c. You must add #include <sys/types.h> at the top,
916 and delete the #define for size_t.
918 You need to build Emacs in the Berkeley universe with
919 the `ucb' command, as in `ucb make' or `ucb build-install'.
921 In OSx 4.0, it seems necessary to add the following two lines
922 to `src/m/pyramid.h':
923 #define _longjmp longjmp
924 #define _setjmp setjmp
926 In Pyramid system 2.5 there has been a compiler bug making
927 Emacs crash just after screen-splitting with Qnil containing 0.
928 A compiler that fixes this is Pyramid customer number 8494,
929 internal number 1923.
931 Some versions of the pyramid compiler get fatal
932 errors when the -gx compiler switch is used; if this
933 happens to you, change `src/m/pyramid.h' to define
934 C_DEBUG_SWITCH with an empty definition.
936 Some old system versions may require you to define PYRAMID_OLD
937 in when alloca.s is preprocessed, in order to define _longjmp and _setjmp.
939 Sequent Balance (ns32k-sequent-bsd4.2 or ns32k-sequent-bsd4.3)
941 Emacs 18.51 worked on system version 3.0. 18.52 is said to work.
942 Delete some lines at the end of `src/m/sequent.h' for earlier system
945 Sequent Symmetry (i386-sequent-bsd, i386-sequent-ptx, i386-sequent-ptx4)
947 19.33 has changes to support ptx 4 (a modified SVR4).
949 Emacs 19 should work on Dynix (BSD). However, if you compile with
950 the Sequent compiler, you may find Emacs does not restore the
951 terminal settings on exit. If this happens, compile with GCC.
953 Emacs 19.27 contains patches that should support
954 DYNIX/ptx 1.4 and 2.1 with the native cc compiler.
956 GCC can't compile src/process.c due to a non-standard Sequent asm
957 keyword extension supported by cc and used for the network byte/word
958 swapping functions in the PTX /usr/include/netinet/in.h file. GCC
959 2.5.8 includes the file <sys/byteorder.h> which can be included into
960 netinet/in.h to perform these byte/word swapping functions in the
961 same manner. Patches have been submitted to the FSF against GCC
962 2.6.0 to fix this problem and allow Emacs to be built with GCC.
964 If your machine does not have TCP/IP installed, you will have to edit the
965 src/s/ptx.h file and comment out #define TCPIP_INSTALLED.
967 Siemens Nixdorf RM600 and RM400 (mips-siemens-sysv4)
969 Changes merged in 19.29. This configuration should also work for
970 Pyramid MIS Server running DC-OSX 1.x. The version configured with
971 `--with-x' works without any modifications, but `--with-x-toolkit'
972 works only if the Athena library and the Toolkit library are linked
973 statically. For this, edit `src/Makefile' after the `configure' run
974 and modify the lines with `-lXaw' and `-lXt' as follows:
976 LIBW= /usr/lib/libXaw.a
977 LIBXT= $(LIBW) -lXmu /usr/lib/libXt.a $(LIBXTR6) -lXext
979 In addition, `--with-x-toolkit=motif' works only
980 if the Motif library and the Toolkit library are linked statically.
981 To do this, edit `src/Makefile' after the `configure' run
982 and modify the lines with `-lXm' and `-lXt' as follows:
984 LIBW= /usr/lib/libXm.a /usr/ccs/lib/libgen.a
985 LIBXT= $(LIBW) -lXmu /usr/lib/libXt.a $(LIBXTR6) -lXext
987 SONY News (m68k-sony-bsd4.2 or m68k-sony-bsd4.3)
989 18.52 worked. Use m68k-sony-bsd4.3 for system release 3.
991 SONY News 3000 series (RISC NEWS) (mips-sony-bsd)
993 The 19.26 pretest is reported to work.
995 Some versions of the operating system give SIGTRAP for division by zero
996 instead of the usual signals. This causes division by zero
997 to make Emacs crash. The system should be fixed to give the proper signal.
998 Changing Emacs is not a proper solution, because it would prevent
999 Emacs from working under any debugger. But you can change init_data
1000 in data.c if you wish.
1002 Stardent i860 (i860-stardent-sysv4.0)
1004 19.26 pretest reported to work.
1006 Stardent 1500 or 3000
1010 Stride (m68k-stride-sysv)
1012 Works (most recent news for 18.30) on their release 2.0.
1013 For release 2.2, see the end of `src/m/stride.h'.
1014 It may be possible to run on their V.1 system but changes
1015 in the s- file would be needed.
1017 Sun 3, Sun 4 (sparc), Sun 386 (m68k-sun-sunos, sparc-sun-sunos, i386-sun-sunos,
1018 sparc-sun-sunos4.1.3noshr, sparc-sun-solaris2.*,
1019 i386-sun-solaris2.*, sparc*-*-linux-gnu)
1021 To build a 64-bit Emacs (with larger maximum buffer size and
1022 including large file support) on a Solaris system which supports
1023 64-bit executables, use the Sun compiler, configuring something like
1024 this (see the cc documentation for information on 64-bit
1025 compilation): env CC="cc -xarch=v9" ./configure
1027 As of version 2.95, GCC doesn't support the 64-bit ABI properly, but
1030 Some versions of Solaris 8 have a bug in their XIM (X Input Method)
1031 implementation which causes Emacs to dump core when one of several
1032 frames is closed. To avoid this, either install patch 108773-12
1033 (for Sparc) or 108874-12 (for x86), or configure Emacs with the
1034 `--with-xim=no' switch (you can use Leim input methods instead).
1036 On Solaris 2.7, building Emacs with WorkShop Compilers 5.0 98/12/15
1037 C 5.0 failed, apparently with non-default CFLAGS, most probably due to
1038 compiler bugs. Using Sun Solaris 2.7 Sun WorkShop 6 update 1 C
1039 release was reported to work without problems. It worked OK on
1040 another system with Solaris 8 using apparently the same 5.0 compiler
1041 and the default CFLAGS.
1043 Emacs 20.5 and later work on SPARC GNU/Linux with the 32-bit ABI.
1044 As of release 2.95, GCC doesn't work properly with the 64-bit ABI
1045 (applicable on UltraSPARC), but that isn't the default mode.
1047 Emacs 20.3 fails to build on Solaris 2.5 if you use GCC 2.7.2.3.
1048 Installing GCC 2.8 fixes the problem.
1050 19.32 works on Solaris 2.4 and 2.5. On Solaris 2.5
1051 you may need one of these patches to prevent Emacs from crashing
1053 103093-03: [README] SunOS 5.5: kernel patch (2140557 bytes)
1054 102832-01: [README] OpenWindows 3.5: Xview Jumbo Patch (4181613 bytes)
1055 103242-04: [README] SunOS 5.5: linker patch (595363 bytes)
1057 There are reports that using SunSoft cc with -xO4 -xdepend produces
1058 bad code for some part of Emacs.
1060 Emacs works ok Sunos 4.1.x
1061 provided you completely replace your C shared library
1062 using one of the SunOS 4.1.x jumbo replacement patches from Sun.
1063 Here are the patch numbers for Sunos 4.1.3:
1064 100890-10 SunOS 4.1.3: domestic libc jumbo patch
1065 100891-10 SunOS 4.1.3: international libc jumbo patch
1067 Some people report that Emacs crashes immediately on startup when
1068 used with a non-X terminal, but we think this is due to compiling
1069 with GCC and failing to use GCC's "fixed" system header files.
1071 Some Sun versions of X windows use the clipboard, not the selections,
1072 for transferring text between clients. The Cut, Paste and Copy items
1073 in the menu bar Edit menu work with the clipboard.
1075 It's important to include the SunOS version number in the
1076 configuration name. For example, for SunOS release 4.0 on a Sun 3,
1077 use `m68k-sun-sunos4.0'; for SunOS release 4.1 on a Sparc, use
1078 `sparc-sun-sunos4.1'. For SunOS release 4.1.3 on a Sparc, use
1079 `sparc-sun-sunos4.1.3'. Note that shared libraries are now
1080 used by default on SunOS 4.1.
1082 A user reported irreproducible segmentation faults when using 19.29
1083 on Solaris 2.3 and 2.4 after compiling it with the Sun compiler.
1084 The problem went away when GCC 2.7.0 was used instead. We do not know
1085 whether anything in Emacs is partly to blame for this.
1087 X11R6 is set up to make shared libraries only, on Sunos 4.
1088 Therefore, in order to link Emacs, you need to create static X libraries.
1089 To do this, rebuild X11 after setting
1090 #define ForceNormalLib YES
1091 #define SeparateSharedCompile YES
1092 in site.def (after #ifdef AfterVendorCF).
1094 Use `m68k' for the 68000-based Sun boxes, `sparc' for Sparcstations,
1095 and `i386' for Sun Roadrunners. i386 calls for Sunos4.0.
1097 If you compile with Sun's ANSI compiler acc, you need additional options
1098 when linking temacs, such as
1099 /usr/lang/SC2.0.1/values-Xt.o -L/usr/lang/SC2.0.1/cg87 -L/usr/lang/SC2.0.1
1100 (those should be added just before the libraries) and you need to
1101 add -lansi just before -lc. The precise file names depend on the
1102 compiler version, so we cannot easily arrange to supply them.
1104 On SunOS 4.1.1, do not use /usr/5bin/cc. You can use gcc or/usr/bin/cc.
1105 Make sure the environment variable LD_LIBRARY_PATH is not defined.
1107 Some people report crashes on SunOS 4.1.3 if SYSTEM_MALLOC is defined.
1108 Others have reported that Emacs works if SYSTEM_MALLOC is defined, and not
1109 if it is undefined. So far we do not know why results vary in this way.
1110 The sources are set up so that SYSTEM_MALLOC is defined; if that crashes,
1111 or if you want the benefit of the relocating memory allocator, you can
1112 try enabling the #undef SYSTEM_MALLOC in src/s/sunos4-1-3.h.
1114 On Solaris 2, you need to install patch 100947-02 to fix a system bug.
1115 Presumably this patch comes from Sun. You must alter the definition of
1116 LD_SWITCH_SYSTEM if your X11 libraries are not in /usr/openwin/lib.
1117 You must make sure that /usr/ucblib is not in your LD_LIBRARY_PATH.
1119 On Solaris 2.2, with a multiprocessor SparcCenter 1000, Emacs 19.17 is
1120 reported to hang sometimes if it exits while it has one or more
1121 subprocesses (e.g. the `wakeup' subprocess used by `display-time').
1122 Emacs and its subprocesses become zombies, and in their zombie state
1123 slow down their host and disable rlogin and telnet. This is most
1124 likely due to a bug in Solaris 2.2's multiprocessor support,
1125 rather than an Emacs bug.
1127 On Solaris, do not use /usr/ucb/cc. Use /opt/SUNWspro/bin/cc. Make
1128 sure that /usr/ccs/bin and /opt/SUNWspro/bin are in your PATH before
1129 /usr/ucb. (Most free software packages have the same requirement on
1132 If you have trouble using open-network-stream, get the distribution
1133 of `bind' (the BSD name-server), build libresolv.a, and link Emacs
1134 with -lresolv, by copying the #definition of LIBS_SYSTEM in
1135 src/s/sunos4-1.h to src/config.h. This problem is due to obsolete
1136 software in the nonshared standard library.
1138 If you want to use SunWindows, define HAVE_SUN_WINDOWS
1139 in config.h to enable a special interface called `emacstool'.
1140 The definition must *precede* the #include "machine.h".
1141 System version 3.2 is required for this facility to work.
1143 We recommend that you instead use the X window system, which
1144 has technical advantages, is an industry standard, and is also
1145 free software. The FSF does not support the SunWindows code;
1146 we installed it only on the understanding we would not let it
1147 divert our efforts from what we think is important.
1149 If you are compiling for X windows, and the X window library was
1150 compiled to use the 68881, then you must edit config.h according
1151 the comments at the end of `src/m/sun3.h'.
1153 Note that Emacs on a Sun is not really as big as it looks.
1154 As dumped, it includes around 200k of zeros between the
1155 original text section and the original data section
1156 (now remapped as part of the text). These are never
1159 To build a single Emacs that will run on Sun 2 and Sun 3
1160 HARDWARE, just build it on the Sun 2.
1162 On Sunos 4.1.3, the word is that Emacs can loop infinitely
1163 on startup with X due perhaps to a bug in Sunos. Installing all of
1164 these Sun patches fixes the problem. We don't know which of them
1165 are really relevant.

1174 Tadpole 68K (m68k-tadpole-sysv)
1176 Changes merged in 19.1.
1178 You may need to edit Makefile to change the variables LIBDIR and
1179 BINDIR from /usr/local to /usr/contrib.
1181 To give movemail access to /usr/mail, you may need to execute
1183 chmod 2755 etc/movemail; chgrp mail etc/movemail
1185 Tahoe (tahoe-tahoe-bsd4.2 or tahoe-tahoe-bsd4.3)
1187 18.52 was known to work on some Tahoes, but a compiler bug intervenes
1188 on others. Some Emacs versions have worked in Unisys 1r4
1189 (not in 1r3) and CCI I.21.
1191 If you have trouble compiling `lib-src/loadst.c', turn off the definition
1192 of DKSTAT_HEADER_FILE in `src/m/tahoe.h'.
1194 Tandem Integrity S2 (mips-tandem-sysv)
1196 Changes merged in 18.56 but subprocess support is turned off.
1197 You will probably want to see if you can make subprocesses work.
1199 You must edit `lib-src/Makefile' to define LOADLIBES = -mld.
1201 Tektronix XD88 (m88k-tektronix-sysv3*)
1203 The 19.26 pretest was reported to work.
1204 Minor changes merged in 19.19.
1206 Tektronix 16000 box (6130?) (ns16k-tektronix-bsd)
1210 Tektronix 4300 (m68k-tektronix-bsd)
1212 Emacs 19.26 pretest reported to work.
1214 Titan P2 or P3 (titan-titan-sysv)
1216 Changes probably merged in version 19.
1218 Ustation E30 (SS5E) (m68k-unisys-unipl)
1220 Changes merged in 18.52; don't know whether they work.
1222 Vaxen running Berkeley Unix (vax-dec-bsd4.1, vax-dec-bsd4.2, vax-dec-bsd4.3),
1223 Ultrix (vax-dec-ultrix),
1224 System V (vax-dec-sysv0, vax-dec-sysv2), or
1229 See under Ultrix for problems using X windows on Ultrix (vax-dec-ultrix).
1231 18.27 worked on System V rel 2 (vax-dec-sysv2).
1233 18.36 worked on System V rel 0 (vax-dec-sysv0).
1235 Richard Levitte <levitte@e.kth.se> distributes a set of patches to
1236 Emacs 18.59 to make it work nicely under VMS. Emacs 19 probably
1237 won't work very well, or even compile. Levitte is working on a
1238 port, so these problems should be fixed in the near future.
1240 Whitechapel MG1 (ns16k-whitechapel-?)
1242 May work. Supposedly no changes were needed except in `src/m/mg1.h'
1243 file. I do not know what Unix version runs on them.
1245 Wicat (m68k-wicat-sysv)
1247 Changes merged as of 18.6; whether they work is unknown.
1248 See comments in `src/m/wicat.h' for things you should change
1249 depending on the system and compiler version you have.
1251 Here are notes about some of the systems supported:
1253 Berkeley 4.1 (bsd4.1)
1257 Berkeley 4.2 (bsd4.2)
1259 Works on several machines.
1261 Berkeley 4.3 (bsd4.3)
1263 Works, on Vaxes at least.
1267 The following was written for Emacs 18.59 and has been
1268 slightly adapted for Emacs 19. It may need more change to be correct.
1270 Use s/usg5-4.h for Esix System V 4.0.[34] systems if you also have
1271 XFree86. If you insist on using the Esix X Window libraries, good
1272 luck. s/esix5r4.h provides a starting point, but doesn't seem to
1273 work consistently. The basic problems involve the need to load
1274 -lX11 *last* in the link command, and even then some things break.
1275 You get best results by installing XFree86 and forgetting about the
1276 Esix stuff unless you want to run IXI xdt3, which really only needs
1277 the Esix X11 shared libraries.
1279 To compile with XFree86, make sure that your LD_LIBRARY_PATH
1280 contains /usr/X386/lib. Be careful if you also have the Esix X
1281 Window libraries that /usr/X386/lib appears *first* in the
1282 LD_LIBRARY_PATH. Then define C_SWITCH_X_SYSTEM -I/usr/X386/include.
1284 Linux (actually GNU/Linux)
1286 Most of the complete systems which use the Linux kernel are close
1287 enough to the GNU system to be considered variant GNU systems. We
1288 call them "Linux-based GNU systems," or GNU/Linux for short.
1290 It is not coincidence that many of the other components used with
1291 Linux--including GNU Emacs--were developed specifically for the GNU
1292 project. The GNU project was launched in 1984 to develop a free
1293 complete Unix-like operating system. To reach this goal, we had to
1294 develop whatever system components were not available as freely
1295 redistributable software from some other source.
1297 The GNU project wants users of GNU/Linux systems to be aware of how
1298 these systems relate to the GNU project, because that will help
1299 spread the GNU idea that software should be free--and thus encourage
1300 people to write more free software. See the file LINUX-GNU in this
1301 directory for more explanation.
1305 See under "Intel 386".
1309 For installation on MSDOS, see the file INSTALL (search for `MSDOG',
1310 near the end of the file). See the "MS-DOS" chapter of the manual
1311 for information about using Emacs on MSDOS.
1314 If you have TCP but not X, you need to edit src/s/sco4.h
1315 to define HAVE_SOCKETS.
1317 If you are using MMDF instead of sendmail, you need to remove
1318 /usr/lib/sendmail or modify lisp/paths.el before compiling.
1319 lisp/paths.el (which is loaded during the build) will attempt to use
1320 sendmail if it exists.
1322 If you are using SMAIL, you need to define the macro
1325 System V rel 0 (usg5.0)
1327 Works, on Vaxes and 3bxxx's.
1328 There are some problems in 18.37 due to shortnames/cccp problems:
1329 use the emacs 17 cpp if you have it.
1331 System V rel 2 (usg5.2)
1333 Works on various machines.
1334 On some (maybe all) machines the library -lPW exists and contains
1335 a version of `alloca'. On these machines, to use it, put
1337 #define LIB_STANDARD -lPW -lc
1338 in the `src/m/MACHINENAME.h' file for the machine.
1340 If you find that the character Meta-DEL makes Emacs crash,
1341 find where function init_sys_modes in sysdep.c sets sg.c_cc[VQUIT]
1342 and make it store 7 there. I have as yet no evidence of whether
1343 this problem, known in HP/UX, exists in other system V versions.
1345 System V rel 2.2 (usg5.2.2)
1347 In 5.2.2 AT&T undid, incompatibly, their previous incompatible
1348 change to the way the nlist library is called. A different s- file
1349 is used to enable the other interface.
1351 They call themselves the right choice--can't they choose?
1353 Emacs version 18 unexec is currently not working properly
1354 on 5.2.2. Nobody knows why yet. A workaround is to define
1355 NO_REMAP. It is not yet known whether this applies to all
1356 machines running 5.2.2.
1358 System V rel 3 (usg5.3)
1360 Some versions of this system support ptys and BSD-style sockets.
1361 On such systems, you should define HAVE_PTYS and HAVE_SOCKETS in config.h.
1363 If you want to link Emacs with shared libraries, define
1364 USG_SHARED_LIBRARIES.
1366 You may have to add ANSI idempotence #-lines to your sys/types.h
1367 file to get Emacs to compile correctly. This may be necessary on
1368 other pre-ANSI systems as well.
1370 On an AT&T 6386WGS using System V Release 3.2 and X11R3, the X support
1371 cannot be made to work. Whether or not the GNU relocating malloc is
1372 used, the symptom is that the first call Emacs makes to sbrk(0) returns
1373 (char *)-1. Sorry, you're stuck with character-only mode. Try
1374 installing Xfree86 to fix this.
1376 System V rel 4.0.3 and 4.0.4 (usg5.4)
1378 Supported, including shared libraries for ELF, but ptys do not work
1379 because TIOCGPGRP fails to work on ptys (but Dell 2.2 seems to have
1380 fixed this). This failure is probably due to a misunderstanding of
1381 the consequences of the POSIX spec: many system designers mistakenly
1382 think that POSIX requires this feature to fail. This is untrue;
1383 ptys are an extension, and POSIX says that extensions *when used*
1384 may change the action of standard facilities in any fashion.
1386 If you get compilation errors about wrong number of
1387 arguments to getpgrp, define GETPGRP_NO_ARG.
1389 The standard C preprocessor may generate xmakefile incorrectly. However,
1390 /lib/cpp will work, so use `make CPP=/lib/cpp'. Standard cpp
1391 seems to work OK under Dell 2.2.
1393 Some versions 3 and earlier of V.4, on the Intel 386 and 860, had
1394 problems in the X11 libraries. These prevent Emacs from working
1395 with X. You can use Emacs with X provided your copy of X is based
1396 on X11 release 4 or newer, or is Dell's 2.2 (which is a 4.0.3).
1397 Unfortunately, the only way you can tell whether your X11 library is
1398 new enough is to try compiling Emacs to use X. If emacs runs, your
1399 X11 library is new enough.
1401 In this context, GSV4 and GSV4i are alternate names for X11R4.
1402 OL2.* is X11R3 based. OL3 is in between X11R3 and X11R4, and may or
1403 may not work, depending on who made the Unix system. If the library
1404 libXol is part of the X distribution, then you have X11R3 and Emacs
1407 Most versions of V.4 support sockets. If `/usr/lib/libsocket.so'
1408 exists, your system supports them. If yours does not, you must add
1409 #undef HAVE_SOCKETS in config.h, after the inclusion of s-usg5-4.h.
1410 (Any system that supports Internet should implement sockets.)
1414 Recent versions of Ultrix appear to support the features of Berkeley 4.3.
1415 Ultrix was at the BSD 4.2 level for a long time after BSD 4.3 came out.
1417 Ultrix 3.0 has incompatibilities in its X library if you have the
1418 Ultrix version of X (UWS version 2.0). To solve them, you need to
1419 prevent XvmsAlloc.o in Xlib from being used. Israel Pinkas says:
1421 I added the following lines to config.h after the X defines:
1423 #if defined(ultrix) && defined(X11)
1424 #define OBJECTS_SYSTEM calloc.o
1427 Then I ran the following:
1429 ar x /usr/lib/libc.a calloc.o
1431 The problem is said to be gone in UWS version 2.1.
1433 Uniplus 5.2 (unipl5.2)
1435 Works, on Dual machines at least.
1439 Richard Levitte <levitte@e.kth.se> distributes a set of patches to
1440 Emacs 18.59 to make it work nicely under VMS. Emacs 19 probably
1441 won't work very well, or even compile. Levitte is working on a
1442 port, so these problems should be fixed in the near future.
1444 Note that Emacs for VMS is usually distributed in a special VMS
1445 distribution. See the file ../vms/VMSINSTALL for info on moving
1446 Unix distributions to VMS, and other VMS-related topics.
1448 Windows NT/95/98/ME/2000
1450 For installation on all versions of the MS-Windows platform, see the
1455 Should work in 18.50, but you will need to edit the files
1456 `lib-src/Makefile' and `src/ymakefile'
1457 (see the comments that mention "Xenix" for what to change.)
1458 Compiling Emacs with -O is said not to work.
1460 If you want Emacs to work with Smail (installed as /usr/bin/smail)
1461 then add the line #define SMAIL to config.h.
1463 The file etc/XENIX suggests some useful things to do to Xenix
1464 to make the Emacs meta key work.
