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 Apollo running X Windows (m68k-apollo-bsd)
107 Apollo version now supports dumping. It has been tested on SR10.3 and
108 SR10.4. It certainly requires at least SR10.0, and maybe SR10.2. Be sure
109 to build in the BSD environment.
111 By default, everything is compiled with the switch "-W0,-opt,2". Don't try
112 to change this to full optimization (-O). The full optimizer (in Domain CC
113 6.7, 6.8 and 6.9) generates some bad code in several modules which causes
114 the emacs window, under X, to be refreshed with each keystroke.
116 The configuration stuff should work for the most part. However, some Domain
117 installations may have to edit src/Makefile manually after it is created.
118 There are too many versions of both cc and X to automate this easily.
120 In `lib-src/Makefile', emacsclient and emacsserver compile and work fine
121 under CC 6.9. They now probably work under other versions of the compiler,
124 The Apollo Domain CC compiler will issue quite a few warning messages,
125 mostly complaining about incompatible pointers. In general, these are
126 harmless and can be ignored. If you discover otherwise, please submit a bug
127 report identifying the problem in detail.
129 When you try to dump emacs, you may get the message ".rwdi section needs
130 relocation." This means you are linking with some code that has compressed
131 data sections. In some cases this comes from linking with X libraries. Try
132 using shared X libraries instead. With some versions of Domain/OS this is
133 as simple as removing the "-lX11" from the LIBX line in src/Makefile.
135 When running the configure script, use the configuration name
136 "m68k-apollo-bsd". You will also need to use the "-with-gcc=no" and
137 "-with-x" options. Depending upon your site configuration, you may have to
138 use other configure options, as well. Examine the INSTALL file for other
141 Check out the file 'lisp/x-apollo.el'. To use it, add
145 to your .emacs file. It provides useful default Apollo function key
148 AT&T 3b2, 3b5, 3b15, 3b20 (we32k-att-sysv)
150 Emacs will probably not work with certain kernel constants too small.
152 In param.h CDLIMIT should be at least (1L << 12) in order to allow
153 processes to write up to 2 Mbyte files. This parameter is configurable
154 by normal means in /etc/master.d/kernel; examine that file for the
155 symbol CDLIMIT or ULIMIT, and raise it by several powers of 2. Then
156 do normal kernel rebuild things via "cd /boot; mkboot -k KERNEL" and so
159 In seg.h NSEGP and STACKSEG should be at least 16 and 4 respectively
160 to allow processes with total size of up to 2Mbytes.
161 However, I'm told it is unlikely this would fail to be true.
163 The MAXMEM may also prevent Emacs from running. The file
164 3B-MAXMEM in this directory explains how to increase MAXMEM.
166 On some of these machines, you may need to define IN_SCCS_ID
167 in config.h to make Emacs work. Supposedly you can tell whether
168 this is necessary by checking something in /usr/include/sys/time.h;
169 we do not know precisely what.
171 AT&T 7300 or 3b1 (m68k-att-sysv)
173 18.52 worked. If you have strange troubles with dumping
174 Emacs, delete the last few lines from `src/m/7300.h' and recompile.
175 These lines are supposed to produce a sharable executable.
177 `src/m/7300.h' defines SHORTNAMES because operating system versions
178 older than 3.5 did not support long symbol names. Version 3.5 does
179 support them, so you can remove the #define SHORTNAMES in that
182 Bull DPX/2 models 2nn or 3nn (m68k-bull-sysv3)
184 Minor fixes merged into 19.19, which should work with CC or GCC.
186 You should compile with all the POSIX stuff: undef _SYSV and define
187 _POSIX_SOURCE, _XOPEN_SOURCE and _BULL_SOURCE.
189 On bos2.00.45 there is a bug that makes the F_SETOWN fcntl
190 call enters in an infinite loop. F_SETOWN_BUG has been defined to avoid
193 Bull DPX/20 (rs6000-bull-bosx)
197 Bull sps7 (m68k-bull-sysv2)
199 Changes partially merged in version 19, but some fixes are probably required.
205 Celerity (celerity-celerity-bsd4.2)
207 Version 18.49 worked. This configuration name is a hack, because we
208 don't know the processor used by Celerities. If someone
209 who uses a Celerity could get in touch with us, we can teach
210 config.sub a better name for the configuration.
212 Clipper (clipper-???)
214 Version 19 has support for some brand of clipper system. If you
215 have successfully built Emacs 19 on some sort of clipper system, let
216 us know so we can flesh out this entry.
218 Note that the Orion 105 is also a clipper, but some system-related
219 parameters are different.
221 Convex (c1-convex-bsd, c2-convex-bsd, c32-convex-bsd, c34-convex-bsd,
224 Support updated and residual bugs fixed in 19.26.
226 Cubix QBx/386 (i386-cubix-sysv)
228 Changes merged in 19.1. Systems before 2/A/0 may fail to compile etags.c
229 due to a compiler bug.
231 Cydra 5 (cydra-cydrome-sysv)
233 18.51 worked in one version of their operating system but stopped
234 working in a newer version. This has not been fixed.
236 Data General Aviion (m88k-dg-dgux)
238 19.23 works; however, the GCC provided with DGUX 5.4R3.00 fails to
239 compile src/emacs.c. GCC 2.5.8 does work.
240 The 19.26 pretest was reported to work; no word on which compiler.
241 System versions other than DGUX 5.4R3.00 have not been tested.
243 DGUX 5.4R3.10 works with 19.29 and 19.30.
245 DGUX R4.11 contains changes to the stdio internals and it doesn't work
246 with versions before 20.2 without patches. 20.2 works in interactive
247 mode but usually fails in batch mode. The problem is that using
248 stderr in the dumped emacs usually leads to a segmentation fault.
249 Only m88k has been tested.
251 DECstation (mips-dec-ultrix or mips-dec-osf)
253 This machine is the older Mips-based DECstation.
254 Emacs should now work on the Alpha CPU.
256 19.25 works on Ultrix 4.2. The 19.26 pretest was reported to work
257 on Ultrix 4.2a and on 4.4.
259 One user reported 19.25 did not work at all with --with-x-toolkit
260 using X11R5 patch level 10, but worked ok with X11R5 pl26.
262 See under Ultrix for problems using X windows on Ultrix.
263 Note that this is a MIPS machine.
265 For Ultrix versions 4.1 or earlier, you may need to define
266 SYSTEM_MALLOC in `src/m/pmax.h', because XvmsAlloc.o in libX11.a seems
267 to insist on defining malloc itself.
269 For Ultrix versions prior to 4.0, you may need to delete
270 the definition of START_FILES from `src/m/pmax.h'.
272 Motorola Delta 147 (m68k-motorola-sysv)
274 The EMacs 19.26 pretest was reported to work.
276 Motorola Delta boxes running System V/68 release 3.
277 Tested on 147 board with SVR3V7, no X and gcc.
278 Tested on 167 board with SVR3V7, no X, cc, gnucc and gcc.
279 Reports say it works with X too.
281 The installation script chooses the compiler itself. gnucc is
284 Motorola Delta 187 (m88k-motorola-sysv,
285 m88k-motorola-sysvr4, or
286 m88k-motorola-m88kbcs)
288 The 19.26 pretest was reported to run on SVR3. However, if you
289 use --with-x-toolkit on svr3, you will have problems compiling some
290 files because time.h and sys/time.h get included twice.
291 One fix is to edit those files to protect against multiple inclusion.
293 As of version 19.13, Emacs was reported to run under SYSVr3 and SYSVr4.
295 Dual running System V (m68k-dual-sysv)
297 As of 17.46, this worked except for a few changes
300 Dual running Uniplus (m68k-dual-uniplus)
304 Elxsi 6400 (elxsi-elxsi-sysv)
306 Changes for 12.0 release are in 19.1.
307 Dumping should work now.
309 Encore machine (ns16k-encore-bsd)
311 This machine bizarrely uses 4.2BSD modified to use the COFF format
312 for object files. Works (as of 18.40). For the APC processor you
313 must enable two lines at the end of `src/s/umax.h', which are commented
314 out in the file as distributed.
316 WARNING: If you compile Emacs with the "-O" compiler switch, you
317 must also use the "-q enter_exits" switch so that all functions have
318 stack frames. Otherwise routines that call `alloca' all lose.
320 A kernel bug in some system versions causes input characters to be lost
323 Fujitsu DS/90 (sparc-fujitsu-sysv4)
325 Changes merged in 20.3.
327 GEC 63 (local-gec63-usg5.2)
329 Changes are partially merged in version 18, but certainly require
330 more work. Let us know if you get this working, and we'll give it a
331 real configuration name.
333 Gould Power Node (pn-gould-bsd4.2 or pn-gould-bsd4.3)
335 18.36 worked on versions 1.2 and 2.0 of the operating system.
337 On UTX/32 2.0, use pn-gould-bsd4.3.
339 On UTX/32 1.2 and UTX/32S 1.0, use pn-gould-bsd4.2 and note that
340 compiling `lib-src/sorted-doc' tickles a compiler bug: remove the -g
341 flag to cc in the makefile.
343 UTX/32 1.3 has a bug in the bcopy library routine. Fix it by
344 #undef BSTRING in `src/m/gould.h'.
346 Version 19 incorporates support for releases 2.1 and later of UTX/32.
347 A site running a pre-release of 2.1 should #define RELEASE2_1 in config.h.
349 Gould NP1 (np1-gould-bsd)
351 Version 19 supposedly works.
353 Harris Night Hawk (m68k-harris-cxux or m88k-harris-cxux)
355 This port was added in 19.23. The configuration actually tested was
356 a Night Hawk 4800 running CX/UX 7.0.
358 If you have GCC ported and want to build with it, you probably need to
359 change things (like compiler switches) defined in the s/cxux.h file.
361 If you have X11R6 installed in /usr/lib, configure will fail to find
362 it and may find X11R5 instead. To work around this problem, use
363 --x-libraries=/usr/lib when you run configure.
365 With CX/UX 7.0 and later releases, you need to build after setting the
366 SDE_TARGET environment variable to COFF (a port using ELF and shared
367 libraries has not yet been done).
369 Harris Power PC (powerpc-harris-powerunix)
371 Patches have been merged in 19.31.
373 Honeywell XPS100 (xps100-honeywell-sysv)
375 Config file added in version 19.
377 Hewlett-Packard 9000 series 200 or 300 (m68k-hp-bsd or m68k-hp-hpux
380 These machines are 68000-series CPUs running HP/UX
381 (a derivative of sysV with some BSD features) or BSD 4.3 ported by Utah.
382 The operating system suffix determines which system Emacs is built for.
384 Series 200 HPUX runs Emacs only if it has the "HP/UX upgrade".
386 Version 19 works under BSD. The 19.26 pretest was reported
387 to work on HPUX 9. 19.31 works on HPUX 10.01, but there are
388 some problems on 10.10 which have not been resolved. Emacs 19.34
389 works on HPUX 10.20 provided you compile with GCC; with the HP C
390 compiler, subprocess commands do not work.
392 On HPUX 9, Emacs sometimes crashes with SIGBUS or SIGSEGV after you
393 delete a frame. We think this is due to a bug in the X libraries
394 provided by HP. With the alternative X libraries in
395 /usr/contrib/mitX11R5/lib, the problem does not happen.
397 If you are running HP/UX release 8.0 or later, you need the optional
398 "C/ANSI C" software in order to build Emacs (older releases of HP/UX
399 do not require any special software). If the file "/etc/filesets/C"
400 exists on your machine, you have this software, otherwise you do not.
402 Note that HP has used two incompatible assembler syntaxes,
403 and has recently changed the format of C function frames.
404 `src/crt0.c' and `src/alloca.s' have been conditionalised for the new
405 assembler and new function-entry sequence. You may need to define
406 OLD_HP_ASSEMBLER if you are using an older hpux version. If you
407 have an official (bought from HP) series 300 machine you have
408 the new assembler. Kernels that are 5.+ or later have new
409 assembler. A Series 200 that has been upgraded to a 68010
410 processor and a 5.+ kernel has the new compiler.
412 Define C_SWITCH_MACHINE to be +X to make a version of Emacs that
413 runs on both 68010 and 68020 based HP/UX's.
415 Define HPUX_68010 if you are using the new assembler, for
416 a system that has a 68010 without a 68881. This is to say,
417 a s200 (upgraded) or s310.
419 Define the symbol HPUX_NET if you have the optional network features
420 that include the `netunam' system call. This is referred to as
421 Network Services (NS/9000) in HP literature.
423 HP 9000 series 500: not supported.
425 The series 500 has a seriously incompatible memory architecture
426 which relocates data in memory during execution of a program,
427 and support for it would be difficult to implement.
429 HP 9000 series 700 or 800 (Spectrum) (hppa1.0-hp-hpux or hppa1.1-hp-hpux
430 or ...hpux9shr, or ...-nextstep)
432 Use hppa1.1 for the 700 series and hppa1.0 for the 800
433 series machines. (Emacs may not actually care which one you use.)
435 Support for NextSTEP was added in 19.31.
437 Emacs 20 may work on HPUX 10. You need patch PHSS_6202 to install
438 the Xaw and Xmu libraries. On HPUX 10.20 you may need to compile with GCC;
439 when Emacs was compiled with HP's C compiler, HP92453-01 A.10.32.03,
440 the subprocess features failed to work.
442 19.26 is believed to work on HPUX 9 provided you compile with GCC.
443 As of version 19.16, Emacs was reported to build (using GCC) and run
444 on HP 9000/700 series machines running HP/UX versions 8.07 and 9.01.
445 The HP compiler is known to fail on some versions if you use +O3,
446 but it may work with lower optimization levels.
448 Use hppa1.1-hp-hpux9shr to use shared libraries on HPUX version 9.
449 You may need to create the X libraries libXaw.a and libXmu.a from
450 the MIT X distribute, and you may need to edit src/Makefile's
451 definition of LIBXT to look like this:
453 LIBXT= $(LIBW) -lXmu -lXt $(LIBXTR6) -lXext
455 Some people report trouble using the GNU memory allocator under
456 HP/UX version 9. The problems often manifest as lots of ^@'s in the
459 We are told that these problems go away if you obtain the latest
460 patches for the HP/UX C compiler. James J Dempsey
461 <jjd@spserv.bbn.com> says that this set of versions works for him:
463 HP92453-01 A.09.28 HP C Compiler
465 HP92453-01 A.09.28 HP C Compiler
466 HP-UX SLLIC/OPTIMIZER HP-UX.09.00.23 02/18/93
467 Ucode Code Generator - HP-UX.09.00.23.5 (patch) 2/18/93
469 For 700 series machines, the HP-UX patch needed is known as
470 PHSS_2653. (Perhaps for 800 series machines as well; we don't
471 know.) If you are on the Internet, you should be able to obtain
472 this patch by using telnet to access the machine
473 support.mayfield.hp.com and logging in as "hpslreg" and following
474 the instructions there. Or you may be able to use this
477 HP Patch Server: http://support.mayfield.hp.com/patches/html/patches.html
478 HP Support Line: http://support.mayfield.hp.com
480 Please do not ask FSF for further support on this. If you have any
481 trouble obtaining the patch, contact HP Software Support.
483 If your buffer fills up with nulls (^@) at some point, it could well
484 be that problem. That problem does not happen when people use GCC
485 to compile Emacs. On the other hand, the HP compiler version 9.34
486 was reported to work for the 19.26 pretest. 9.65 was also reported to work.
488 If you turn on the DSUSP character (delayed suspend),
489 Emacs 19.26 does not know how to turn it off on HPUX.
490 You need to turn it off manually.
492 If you are running HP/UX release 8.0 or later, you need the optional
493 "C/ANSI C" software in order to build Emacs (older releases of HP/UX
494 do not require any special software). If the file "/etc/filesets/C"
495 exists on your machine, you have this software, otherwise you do not.
497 High Level Hardware Orion (orion-highlevel-bsd)
499 This is the original microprogrammed hardware.
500 Machine description file ought to work.
502 High Level Hardware Orion 1/05 (clipper-highlevel-bsd)
504 Changes merged in 18.52. This is the one with the Clipper cpu.
505 Note that systems which lack NFS need LOAD_AVE_TYPE changed to `double'.
507 C compiler has a bug; it loops compiling eval.c.
508 Compile it by hand without optimization.
510 HITACHI SR2001/SR2201 series (hppa1.1-hitachi-hiuxwe2)
512 These machines are based on PA architecture running HI-UX/MPP
513 (based on OSF1. `MPP' stands for `Massively Parallel Processor').
515 Emacs 19.34 is believed to work; its pretest was tested
516 both on SR2001 (output of `uname -rv' is `00-01-BB 0') and
519 Emacs 20.7 was reported to build on a system whose `uname -rs'
520 output is `HI-UX/MPP 03-04'.
522 The machine description file is `src/m/sr2k.h' is based on
523 `src/m/hp800.h'. The system description file is `src/s/hiuxwe2.h'
524 based on `src/s/osf1.h'. Note that this system doesn't use COFF.
526 IBM PS/2 (i386-ibm-aix1.1 or i386-ibm-aix1.2)
528 Changes merged in version 19. You may need to copy
529 /usr/lib/samples/hft/hftctl.c to the Emacs src directory.
531 i386-ibm-aix1.1 may not work with certain new X window managers, and
534 IBM RS/6000 (rs6000-ibm-aix*)
536 Emacs 19.26 is believed to work; its pretest was tested.
538 Compiling with the system's `cc' and CFLAGS containing `-O5' might
539 fail because libXbsd isn't found. This is a compiler bug;
540 re-configure Emacs so that it isn't compiled with `-O5'.
542 At last report, Emacs didn't run well on terminals. Informed
543 persons say that the tty VMIN and VTIME settings have been
544 corrupted; if you have a fix, please send it to us.
546 Compiling with -O using the IBM compiler has been known
547 to make Emacs work incorrectly. It's reported that on
548 AIX 3.2.5 with an IBM compiler earlier than 1.03.00.14,
549 cc -O fails for some files. You need to install any
550 PTF containing APAR #IX42810 to bring the compiler to
551 the 1.03.00.14 level to allow optimized compiles.
553 There are reports that IBM compiler versions earlier than 1.03.00.02
554 fail even without -O. However, another report said that compiler
555 version 1.02.01.00 did work, on AIX 3.2.4, with Emacs 19.31.
557 As of 19.11, if you strip the Emacs executable, it ceases to work.
559 If you are using AIX 3.2.3, you may get a core dump when loading
560 ange-ftp. You may be able to fix the problem by defining LIBS_TERMCAP
561 as -ltermcap -lcurses. Please tell us if this fails to work.
563 If anyone can fix the above problems, or confirm that they don't happen
564 with certain versions of various programs, we would appreciate it.
566 IBM RT/PC (romp-ibm-bsd or romp-ibm-aix)
568 Use romp-ibm-bsd for the 4.2-like system and romp-ibm-aix for AIX.
569 19.22 is reported to work under bsd. We don't know about AIX.
571 On BSD, if you have trouble, try compiling with a different compiler.
573 On AIX, the file /usr/lib/samples/hft/hftctl.c must be compiled into
574 hftctl.o, with this result left in the src directory (hftctl.c is
575 part of the standard AIX distribution).
577 window.c must not be compiled with -O on AIX.
579 Integrated Solutions `Optimum V' (m68k-isi-bsd4.2 or -bsd4.3)
581 18.52 said to work on some sort of ISI machine.
582 Version 18.45 worked (running on a Optimum V (VME bus, 68020)
583 BSD 4.2 (3.05e) system). 18.42 is reported to work on
584 a Qbus 68010 system. Has not been tried on `WorkStation' `Cluster
585 Compute Node' `Cluster WorkStation' or `Server Node' (Love the
588 Compilation with -O is rumored to break something.
590 On recent system versions, you may need to undefine the macro UMAX
591 in `lib-src/loadst.c' and `src/getpagesize.h'. They stupidly defined this
592 in a system header file, which confuses Emacs (which thinks that UMAX
593 indicates the Umax operating system).
595 Intel 386 (i386-*-isc, i386-*-esix, i386-*-bsdi2,
596 i386-*-xenix, i386-*-freebsd, i386-*-linux-gnu,
597 i386-*-sol2.4, i386-*-sysv3, i386-intsys-sysv,
598 i386-*-sysv4, i386-*-sysv4.2,
599 i386-*-sysv5.3, i386-*-bsd4.2,
600 i386-*-sco3.2v4, i386-*-bsd386, i386-*-386bsd,
601 i386-*-msdos, i386-*-windowsnt.
602 i386... can be replaced with i486... or i586...)
604 In the above configurations, * means that the manufacturer's name
605 you specify does not matter, and you can use any name you like
606 (but it should not contain any dashes or stars).
608 When using the ISC configurations, be sure to specify the isc
609 version number - for example, if you're running ISC 3.0, use
610 i386-unknown-isc3.0 as your configuration name.
611 Use i386-*-esix for Esix; Emacs runs as of version 19.6.
612 Use i386-*-linux-gnu for GNU/Linux systems; Emacs runs as of version 19.26.
613 Use i386-intsys-sysv for Integrated Solutions 386 machines.
614 It may also be correct for Microport systems.
615 Use i386-*-sco3.2v4 for SCO 3.2v4; Emacs runs as of version 19.26.
617 On GNU/Linux systems, Emacs 19.23 was said to work properly with libc
618 version 4.5.21, but not with 4.5.19. If your system uses QMAGIC
619 for the executable format, you must edit config.h to define LINUX_QMAGIC.
621 On GNU/Linux, configure may fail to put these definitions in config.h:
623 #define HAVE_GETTIMEOFDAY
626 #define HAVE_XSCREENNUMBEROFSCREEN
628 To work around the problem, add those definitions by hand.
629 It is possible that this problem happens only with X11R6.
630 Newer system versions have fixed it.
632 The 19.26 pretest was reported to work on SVR4.3 and on Freebsd.
634 19.29 is reported to crash when using Motif on Solaris 2.5.
635 The reasons are not yet known.
637 Use i386-*-bsdiN for BSDI BSD/OS version N; Emacs runs as of version 19.23.
638 In some system versions, `make' is broken; use GNU make instead.
639 Shell bugs in version 1.0 of BSD/OS cause configure
640 to do the wrong thing with --with-x-toolkit; the workaround is to edit
641 configure to run another shell such as bash.
643 For System V release 3, use i386-*-sysv3.
644 For System V release 4, use i386-*-sysv4.
645 For System V release 4.2, use i386-*-sysv4.2.
647 If you are using Xenix, see notes at end under Xenix.
648 If you are using Esix, see notes at end under Esix.
649 If you are using SCO Unix, see notes at end under SCO.
651 On 386bsd, NetBSD and FreeBSD, at one time, it was necessary to use
652 GNU make, not the system's make. Assuming it's installed as gmake,
653 do `gmake install MAKE=gmake'. However, more recently it is
654 reported that using the system Make on NetBSD 1.3.1 works ok.
656 If you are using System V release 4.2, you may find that `cc -E'
657 puts spurious spaces in `src/xmakefile'. If that happens,
658 specify CPP=/lib/cpp as an option when you run make.
659 There is no problem if you compile with GCC.
661 Note that use of Linux with GCC 2.4 and the DLL 4.4 libraries
662 requires the experimental "net 2" network patches (no relation to
663 Berkeley Net 2). There is a report that (some version of) Linux
664 requires including `/usr/src/linux/include/linux' in buffer.c
665 but no coherent explanation of why that might be so. If it is so,
666 in current versions of Linux, something else should probably be changed.
668 Some sysV.3 systems seem to have bugs in `opendir';
669 for them, alter `config.h' to define NONSYSTEM_DIR_LIBRARY
670 and undefine SYSV_SYSTEM_DIR.
672 If you use optimization on V.3, you may need the option -W2,'-y 0'
673 to prevent certain faulty optimization.
675 On 386/ix, to link with shared libraries, add #define USG_SHARED_LIBRARIES
678 On SCO, there are problems in regexp matching when Emacs is compiled
679 with the system compiler. The compiler version is "Microsoft C
680 version 6", SCO 4.2.0h Dev Sys Maintenance Supplement 01/06/93;
681 Quick C Compiler Version 1.00.46 (Beta). The solution is to compile
684 On ISC systems (2.02 and more recent), don't try to use the versions
685 of X that come with the system; use XFree86 instead.
687 There is no consistency in the handling of certain system header files
690 Some versions have sys/sioctl.h, and require it in sysdep.c.
691 But some versions do not have sys/sioctl.h.
692 For a given version of the system, this may depend on whether you have
693 X Windows or TCP/IP. Define or undefine NO_SIOCTL_H in config.h
694 according to whether you have the file.
696 Likewise, some versions have been known to need sys/ttold.h, sys/stream.h,
697 and sys/ptem.h included in sysdep.c. If your system has these files,
698 try defining NEED_PTEM_H in config.h if you have trouble without it.
700 You may find that adding -I/usr/X/include or -I/usr/netinclude or both
701 to CFLAGS avoids compilation errors on certain systems.
703 Some versions convince sysdep.c to try to use `struct tchars'
704 but define `struct tc' instead; add `#define tchars tc'
705 to config.h to solve this problem.
707 Iris 2500 and Iris 2500 Turbo (m68k-sgi-iris3.5 or m68k-sgi-iris3.6)
709 Version 18 was said to work; use m68k-sgi-iris3.5 for system version 2.5
710 and m68k-sgi-iris3.6 for system version 3.6.
711 Note that the 3030 is the same as the Iris 2500 Turbo.
713 Iris 4D (mips-sgi-irix[456].*)
715 You can build a 64-bit executable (with larger maximum buffer size)
716 on Irix 6.5 by specifying the 64-bit ABI using the `-64' compiler
717 flag or otherwise (see cc(1)). This may work on earlier Irix 6
718 systems if you edit src/s/irix6-0.h following irix6-5.h.
720 If compiling with GCC on Irix 6 yields an error "conflicting types
721 for `initstate'", install GCC 2.95 or a newer version, and this
722 problem should go away. It is possible that this problem results
723 from upgrading the operating system without reinstalling GCC; so you
724 could also try reinstalling the same version of GCC, and telling us
725 whether that fixes the problem.
727 The 19.26 pretest was reported to work on IRIX 4.0.5 and 5.2.
728 19.23 was reported to work on IRIX 5.2, but you may need to install
729 the "compiler_dev.hdr.internal" subsystem in order to compile unexelfsgi.c.
730 19.22 was known to work on all Silicon Graphics machines running
731 IRIX 4.0.5 or IRIX 5.1.
733 Compiling with -O using IRIX compilers prior to 3.10.1 may not work.
734 Don't use -O or use GCC instead.
736 Most IRIX 3.3 systems do not have an ANSI C compiler, but a few do.
737 Compile Emacs 18 with the -cckr switch on these machines.
739 There is a bug in IRIX 3.3 that can sometimes leave ptys owned by root
740 with a permission of 622. This causes malfunctions in use of
741 subprocesses of Emacs. Irix versions 4.0 and later with GNU Emacs
742 versions 18.59 and later fix this bug.
744 Masscomp (m68k-masscomp-rtu)
746 18.36 worked on a 5500DP running RTU v3.1a and compiler version 3.2
747 with minor fixes that are included in 18.37. However, bizarre behavior
748 was reported for 18.36 on a Masscomp (model and version unknown but probably
749 a 68020 system). The report sounds like a compiler bug.
751 A compiler bug affecting statements like
752 unsigned char k; unsigned char *p;... x = p[k];
753 has been reported for "C version 1.2 under RTU 3.1". We do not wish
754 to take the time to install the numerous workarounds required to
755 compensate for this bug.
757 For RTU version 3.1, define FIRST_PTY_LETTER to be 'p' in `src/s/rtu.h'
758 (or #undef and redefine it in config.h) so that ptys will be used.
760 GNU Emacs is said to have no chance of compiling on RTU versions
763 Megatest (m68k-megatest-bsd)
765 Emacs 15 worked; do not have any reports about Emacs 16 or 17
766 but any new bugs are probably not difficult.
768 Mips (mips-mips-riscos, mips-mips-riscos4.0, or mips-mips-bsd)
770 The C compiler on Riscos 4.51 dumps core trying to optimize
771 parts of Emacs. Try without optimization or try GCC.
773 Meanwhile, the linker on that system returns success even if
774 there are undefined symbols; as a result, configure gets the
775 wrong answers to various questions. No work-around is known
776 except to edit src/config.h by hand to indicate which functions
779 Use mips-mips-riscos4.0 for RISCOS version 4.
780 Use mips-mips-bsd with the BSD world.
782 Note that the proper configuration names for DECstations are
783 mips-dec-ultrix and mips-dec-osf.
785 If you are compiling with GCC, then you must run fixincludes;
786 the alternative of using -traditional won't work because
787 the definition of SIGN_EXTEND_CHAR uses the keyword `signed'.
789 If the SYSV world is the default, then you probably need the following
790 line in etc/Makefile:
792 CFLAGS= -g -systype bsd43
794 Some operating systems on MIPS machines give SIGTRAP for division by
795 zero instead of the usual signals. The only real solution is to fix
796 the system to give a proper signal.
798 In the meantime, you can change init_data in data.c if you wish.
799 Change it to handle SIGTRAP as well as SIGFPE. But this will have a
800 great disadvantage: you will not be able to run Emacs under a
801 debugger. I think crashing on division by zero is a lesser problem.
803 dsg@mitre.org reported needing to use --x-libraries=/bsd43/usr/lib
804 on a riscos4bsd site. But it is not clear whether this is needed in
805 general or only because of quirks on a particular site.
807 National Semiconductor 32000 (ns32k-ns-genix)
809 This is for a complete machine from National Semiconductor,
810 running Genix. Changes merged in version 19.
812 NCR Tower 32 (m68k-ncr-sysv2 or m68k-ncr-sysv3)
814 If you are running System V release 2, use m68k-ncr-sysv2.
815 If you are running System V release 3, use m68k-ncr-sysv3.
817 These both worked as of 18.56. If you change `src/ymakefile' so that
818 CFLAGS includes C_OPTIMIZE_SWITCH rather than C_DEBUG_SWITCH, check
819 out the comments in `src/m/tower32.h' (for System V release 2) or
820 `src/m/tower32v3.h' (for System V release 3) about this.
822 There is a report that compilation with -O did not work with 18.54
823 under System V release 2.
825 NCR Intel system (i386-ncr-sysv4.2)
827 This system works in 19.31, but if you don't link it with GNU ld,
828 you may need to set LD_RUN_PATH at link time to specify where
829 to find the X libraries.
831 NEC EWS4800 (mips-nec-sysv4)
833 This system works in 20.4, but you should use the compiler
834 /usr/abiccs/bin/cc (MIPS ABI MODE).
836 NeXT (m68k-next-nextstep)
838 Emacs 19 has not been tested extensively yet, but it seems to work
839 in a NeXTStep 3.0 terminal window, and under the X server called
840 co-Xist. You may need to specify -traditional when src/Makefile
843 NeXT users might want to implement direct operation with NeXTStep,
844 but from the point of view of the GNU project, that is a
847 Thanks to Thorsten Ohl for working on the NeXT port of Emacs 19.
849 Nixdorf Targon 31 (m68k-nixdorf-sysv)
851 Machine description file for version 17 is included in 18
852 but whether it works is not known.
853 `src/unexec.c' bombs if compiled with -O.
854 Note that the "Targon 35" is really a Pyramid.
856 Nu (TI or LMI) (m68k-nu-sysv)
858 Version 18 is believed to work.
860 Paragon OSF/1 (i860-intel-osf1)
862 Changes merged in 19.29.
864 There is a bug in OSF/1 make which claims there is a syntax error
865 in the src/xmakefile. You can successfully build emacs with:
869 Plexus (m68k-plexus-sysv)
873 Pmax (DEC Mips) (mips-dec-ultrix or mips-dec-osf1)
875 See under DECstation, above.
877 Prime EXL (i386-prime-sysv)
879 Minor changes merged in 19.1.
881 Pyramid (pyramid-pyramid-bsd)
883 The 19.26 pretest was observed to work on OSx 5.0, but it is necessary
884 to edit gmalloc.c. You must add #include <sys/types.h> at the top,
885 and delete the #define for size_t.
887 You need to build Emacs in the Berkeley universe with
888 the `ucb' command, as in `ucb make' or `ucb build-install'.
890 In OSx 4.0, it seems necessary to add the following two lines
891 to `src/m/pyramid.h':
892 #define _longjmp longjmp
893 #define _setjmp setjmp
895 In Pyramid system 2.5 there has been a compiler bug making
896 Emacs crash just after screen-splitting with Qnil containing 0.
897 A compiler that fixes this is Pyramid customer number 8494,
898 internal number 1923.
900 Some versions of the pyramid compiler get fatal
901 errors when the -gx compiler switch is used; if this
902 happens to you, change `src/m/pyramid.h' to define
903 C_DEBUG_SWITCH with an empty definition.
905 Some old system versions may require you to define PYRAMID_OLD
906 in when alloca.s is preprocessed, in order to define _longjmp and _setjmp.
908 Sequent Balance (ns32k-sequent-bsd4.2 or ns32k-sequent-bsd4.3)
910 Emacs 18.51 worked on system version 3.0. 18.52 is said to work.
911 Delete some lines at the end of `src/m/sequent.h' for earlier system
914 Sequent Symmetry (i386-sequent-bsd, i386-sequent-ptx, i386-sequent-ptx4)
916 19.33 has changes to support ptx 4 (a modified SVR4).
918 Emacs 19 should work on Dynix (BSD). However, if you compile with
919 the Sequent compiler, you may find Emacs does not restore the
920 terminal settings on exit. If this happens, compile with GCC.
922 Emacs 19.27 contains patches that should support
923 DYNIX/ptx 1.4 and 2.1 with the native cc compiler.
925 GCC can't compile src/process.c due to a non-standard Sequent asm
926 keyword extension supported by cc and used for the network byte/word
927 swapping functions in the PTX /usr/include/netinet/in.h file. GCC
928 2.5.8 includes the file <sys/byteorder.h> which can be included into
929 netinet/in.h to perform these byte/word swapping functions in the
930 same manner. Patches have been submitted to the FSF against GCC
931 2.6.0 to fix this problem and allow Emacs to be built with GCC.
933 If your machine does not have TCP/IP installed, you will have to edit the
934 src/s/ptx.h file and comment out #define TCPIP_INSTALLED.
936 Siemens Nixdorf RM600 and RM400 (mips-siemens-sysv4)
938 Changes merged in 19.29. This configuration should also work for
939 Pyramid MIS Server running DC-OSX 1.x. The version configured with
940 `--with-x' works without any modifications, but `--with-x-toolkit'
941 works only if the Athena library and the Toolkit library are linked
942 statically. For this, edit `src/Makefile' after the `configure' run
943 and modify the lines with `-lXaw' and `-lXt' as follows:
945 LIBW= /usr/lib/libXaw.a
946 LIBXT= $(LIBW) -lXmu /usr/lib/libXt.a $(LIBXTR6) -lXext
948 In addition, `--with-x-toolkit=motif' works only
949 if the Motif library and the Toolkit library are linked statically.
950 To do this, edit `src/Makefile' after the `configure' run
951 and modify the lines with `-lXm' and `-lXt' as follows:
953 LIBW= /usr/lib/libXm.a /usr/ccs/lib/libgen.a
954 LIBXT= $(LIBW) -lXmu /usr/lib/libXt.a $(LIBXTR6) -lXext
956 SONY News (m68k-sony-bsd4.2 or m68k-sony-bsd4.3)
958 18.52 worked. Use m68k-sony-bsd4.3 for system release 3.
960 SONY News 3000 series (RISC NEWS) (mips-sony-bsd)
962 The 19.26 pretest is reported to work.
964 Some versions of the operating system give SIGTRAP for division by zero
965 instead of the usual signals. This causes division by zero
966 to make Emacs crash. The system should be fixed to give the proper signal.
967 Changing Emacs is not a proper solution, because it would prevent
968 Emacs from working under any debugger. But you can change init_data
969 in data.c if you wish.
971 Stardent i860 (i860-stardent-sysv4.0)
973 19.26 pretest reported to work.
975 Stardent 1500 or 3000
979 Stride (m68k-stride-sysv)
981 Works (most recent news for 18.30) on their release 2.0.
982 For release 2.2, see the end of `src/m/stride.h'.
983 It may be possible to run on their V.1 system but changes
984 in the s- file would be needed.
986 Sun 3, Sun 4 (sparc), Sun 386 (m68k-sun-sunos, sparc-sun-sunos, i386-sun-sunos,
987 sparc-sun-sunos4.1.3noshr, sparc-sun-solaris2.*,
988 i386-sun-solaris2.*, sparc*-*-linux-gnu)
990 To build a 64-bit Emacs (with larger maximum buffer size and
991 including large file support) on a Solaris system which supports
992 64-bit executables, use the Sun compiler, configuring something like
993 this (see the cc documentation for information on 64-bit
994 compilation): env CC="cc -xarch=v9" ./configure
996 As of version 2.95, GCC doesn't support the 64-bit ABI properly, but
999 Some versions of Solaris 8 have a bug in their XIM (X Input Method)
1000 implementation which causes Emacs to dump core when one of several
1001 frames is closed. To avoid this, either install patch 108773-12
1002 (for Sparc) or 108874-12 (for x86), or configure Emacs with the
1003 `--with-xim=no' switch (you can use Leim input methods instead).
1005 On Solaris 2.7, building Emacs with WorkShop Compilers 5.0 98/12/15
1006 C 5.0 failed, apparently with non-default CFLAGS, most probably due to
1007 compiler bugs. Using Sun Solaris 2.7 Sun WorkShop 6 update 1 C
1008 release was reported to work without problems. It worked OK on
1009 another system with Solaris 8 using apparently the same 5.0 compiler
1010 and the default CFLAGS.
1012 Emacs 20.5 and later work on SPARC GNU/Linux with the 32-bit ABI.
1013 As of release 2.95, GCC doesn't work properly with the 64-bit ABI
1014 (applicable on UltraSPARC), but that isn't the default mode.
1016 Emacs 20.3 fails to build on Solaris 2.5 if you use GCC 2.7.2.3.
1017 Installing GCC 2.8 fixes the problem.
1019 19.32 works on Solaris 2.4 and 2.5. On Solaris 2.5
1020 you may need one of these patches to prevent Emacs from crashing
1022 103093-03: [README] SunOS 5.5: kernel patch (2140557 bytes)
1023 102832-01: [README] OpenWindows 3.5: Xview Jumbo Patch (4181613 bytes)
1024 103242-04: [README] SunOS 5.5: linker patch (595363 bytes)
1026 There are reports that using SunSoft cc with -xO4 -xdepend produces
1027 bad code for some part of Emacs.
1029 Emacs works ok Sunos 4.1.x
1030 provided you completely replace your C shared library
1031 using one of the SunOS 4.1.x jumbo replacement patches from Sun.
1032 Here are the patch numbers for Sunos 4.1.3:
1033 100890-10 SunOS 4.1.3: domestic libc jumbo patch
1034 100891-10 SunOS 4.1.3: international libc jumbo patch
1036 Some people report that Emacs crashes immediately on startup when
1037 used with a non-X terminal, but we think this is due to compiling
1038 with GCC and failing to use GCC's "fixed" system header files.
1040 Some Sun versions of X windows use the clipboard, not the selections,
1041 for transferring text between clients. The Cut, Paste and Copy items
1042 in the menu bar Edit menu work with the clipboard.
1044 It's important to include the SunOS version number in the
1045 configuration name. For example, for SunOS release 4.0 on a Sun 3,
1046 use `m68k-sun-sunos4.0'; for SunOS release 4.1 on a Sparc, use
1047 `sparc-sun-sunos4.1'. For SunOS release 4.1.3 on a Sparc, use
1048 `sparc-sun-sunos4.1.3'. Note that shared libraries are now
1049 used by default on SunOS 4.1.
1051 A user reported irreproducible segmentation faults when using 19.29
1052 on Solaris 2.3 and 2.4 after compiling it with the Sun compiler.
1053 The problem went away when GCC 2.7.0 was used instead. We do not know
1054 whether anything in Emacs is partly to blame for this.
1056 X11R6 is set up to make shared libraries only, on Sunos 4.
1057 Therefore, in order to link Emacs, you need to create static X libraries.
1058 To do this, rebuild X11 after setting
1059 #define ForceNormalLib YES
1060 #define SeparateSharedCompile YES
1061 in site.def (after #ifdef AfterVendorCF).
1063 Use `m68k' for the 68000-based Sun boxes, `sparc' for Sparcstations,
1064 and `i386' for Sun Roadrunners. i386 calls for Sunos4.0.
1066 If you compile with Sun's ANSI compiler acc, you need additional options
1067 when linking temacs, such as
1068 /usr/lang/SC2.0.1/values-Xt.o -L/usr/lang/SC2.0.1/cg87 -L/usr/lang/SC2.0.1
1069 (those should be added just before the libraries) and you need to
1070 add -lansi just before -lc. The precise file names depend on the
1071 compiler version, so we cannot easily arrange to supply them.
1073 On SunOS 4.1.1, do not use /usr/5bin/cc. You can use gcc or/usr/bin/cc.
1074 Make sure the environment variable LD_LIBRARY_PATH is not defined.
1076 Some people report crashes on SunOS 4.1.3 if SYSTEM_MALLOC is defined.
1077 Others have reported that Emacs works if SYSTEM_MALLOC is defined, and not
1078 if it is undefined. So far we do not know why results vary in this way.
1079 The sources are set up so that SYSTEM_MALLOC is defined; if that crashes,
1080 or if you want the benefit of the relocating memory allocator, you can
1081 try enabling the #undef SYSTEM_MALLOC in src/s/sunos4-1-3.h.
1083 On Solaris 2, you need to install patch 100947-02 to fix a system bug.
1084 Presumably this patch comes from Sun. You must alter the definition of
1085 LD_SWITCH_SYSTEM if your X11 libraries are not in /usr/openwin/lib.
1086 You must make sure that /usr/ucblib is not in your LD_LIBRARY_PATH.
1088 On Solaris 2.2, with a multiprocessor SparcCenter 1000, Emacs 19.17 is
1089 reported to hang sometimes if it exits while it has one or more
1090 subprocesses (e.g. the `wakeup' subprocess used by `display-time').
1091 Emacs and its subprocesses become zombies, and in their zombie state
1092 slow down their host and disable rlogin and telnet. This is most
1093 likely due to a bug in Solaris 2.2's multiprocessor support,
1094 rather than an Emacs bug.
1096 On Solaris, do not use /usr/ucb/cc. Use /opt/SUNWspro/bin/cc. Make
1097 sure that /usr/ccs/bin and /opt/SUNWspro/bin are in your PATH before
1098 /usr/ucb. (Most free software packages have the same requirement on
1101 If you have trouble using open-network-stream, get the distribution
1102 of `bind' (the BSD name-server), build libresolv.a, and link Emacs
1103 with -lresolv, by copying the #definition of LIBS_SYSTEM in
1104 src/s/sunos4-1.h to src/config.h. This problem is due to obsolete
1105 software in the nonshared standard library.
1107 If you want to use SunWindows, define HAVE_SUN_WINDOWS
1108 in config.h to enable a special interface called `emacstool'.
1109 The definition must *precede* the #include "machine.h".
1110 System version 3.2 is required for this facility to work.
1112 We recommend that you instead use the X window system, which
1113 has technical advantages, is an industry standard, and is also
1114 free software. The FSF does not support the SunWindows code;
1115 we installed it only on the understanding we would not let it
1116 divert our efforts from what we think is important.
1118 If you are compiling for X windows, and the X window library was
1119 compiled to use the 68881, then you must edit config.h according
1120 the comments at the end of `src/m/sun3.h'.
1122 Note that Emacs on a Sun is not really as big as it looks.
1123 As dumped, it includes around 200k of zeros between the
1124 original text section and the original data section
1125 (now remapped as part of the text). These are never
1128 To build a single Emacs that will run on Sun 2 and Sun 3
1129 HARDWARE, just build it on the Sun 2.
1131 On Sunos 4.1.3, the word is that Emacs can loop infinitely
1132 on startup with X due perhaps to a bug in Sunos. Installing all of
1133 these Sun patches fixes the problem. We don't know which of them
1134 are really relevant.

1143 Tadpole 68K (m68k-tadpole-sysv)
1145 Changes merged in 19.1.
1147 You may need to edit Makefile to change the variables LIBDIR and
1148 BINDIR from /usr/local to /usr/contrib.
1150 To give movemail access to /usr/mail, you may need to execute
1152 chmod 2755 etc/movemail; chgrp mail etc/movemail
1154 Tahoe (tahoe-tahoe-bsd4.2 or tahoe-tahoe-bsd4.3)
1156 18.52 was known to work on some Tahoes, but a compiler bug intervenes
1157 on others. Some Emacs versions have worked in Unisys 1r4
1158 (not in 1r3) and CCI I.21.
1160 If you have trouble compiling `lib-src/loadst.c', turn off the definition
1161 of DKSTAT_HEADER_FILE in `src/m/tahoe.h'.
1163 Tandem Integrity S2 (mips-tandem-sysv)
1165 Changes merged in 18.56 but subprocess support is turned off.
1166 You will probably want to see if you can make subprocesses work.
1168 You must edit `lib-src/Makefile' to define LOADLIBES = -mld.
1170 Tektronix XD88 (m88k-tektronix-sysv3*)
1172 The 19.26 pretest was reported to work.
1173 Minor changes merged in 19.19.
1175 Tektronix 16000 box (6130?) (ns16k-tektronix-bsd)
1179 Tektronix 4300 (m68k-tektronix-bsd)
1181 Emacs 19.26 pretest reported to work.
1183 Titan P2 or P3 (titan-titan-sysv)
1185 Changes probably merged in version 19.
1187 Ustation E30 (SS5E) (m68k-unisys-unipl)
1189 Changes merged in 18.52; don't know whether they work.
1191 Vaxen running Berkeley Unix (vax-dec-bsd4.1, vax-dec-bsd4.2, vax-dec-bsd4.3),
1192 Ultrix (vax-dec-ultrix),
1193 System V (vax-dec-sysv0, vax-dec-sysv2), or
1198 See under Ultrix for problems using X windows on Ultrix (vax-dec-ultrix).
1200 18.27 worked on System V rel 2 (vax-dec-sysv2).
1202 18.36 worked on System V rel 0 (vax-dec-sysv0).
1204 Richard Levitte <levitte@e.kth.se> distributes a set of patches to
1205 Emacs 18.59 to make it work nicely under VMS. Emacs 19 probably
1206 won't work very well, or even compile. Levitte is working on a
1207 port, so these problems should be fixed in the near future.
1209 Whitechapel MG1 (ns16k-whitechapel-?)
1211 May work. Supposedly no changes were needed except in `src/m/mg1.h'
1212 file. I do not know what Unix version runs on them.
1214 Wicat (m68k-wicat-sysv)
1216 Changes merged as of 18.6; whether they work is unknown.
1217 See comments in `src/m/wicat.h' for things you should change
1218 depending on the system and compiler version you have.
1220 Here are notes about some of the systems supported:
1222 Berkeley 4.1 (bsd4.1)
1226 Berkeley 4.2 (bsd4.2)
1228 Works on several machines.
1230 Berkeley 4.3 (bsd4.3)
1232 Works, on Vaxes at least.
1236 The following was written for Emacs 18.59 and has been
1237 slightly adapted for Emacs 19. It may need more change to be correct.
1239 Use s/usg5-4.h for Esix System V 4.0.[34] systems if you also have
1240 XFree86. If you insist on using the Esix X Window libraries, good
1241 luck. s/esix5r4.h provides a starting point, but doesn't seem to
1242 work consistently. The basic problems involve the need to load
1243 -lX11 *last* in the link command, and even then some things break.
1244 You get best results by installing XFree86 and forgetting about the
1245 Esix stuff unless you want to run IXI xdt3, which really only needs
1246 the Esix X11 shared libraries.
1248 To compile with XFree86, make sure that your LD_LIBRARY_PATH
1249 contains /usr/X386/lib. Be careful if you also have the Esix X
1250 Window libraries that /usr/X386/lib appears *first* in the
1251 LD_LIBRARY_PATH. Then define C_SWITCH_X_SYSTEM -I/usr/X386/include.
1253 Linux (actually GNU/Linux)
1255 Most of the complete systems which use the Linux kernel are close
1256 enough to the GNU system to be considered variant GNU systems. We
1257 call them "Linux-based GNU systems," or GNU/Linux for short.
1259 It is not coincidence that many of the other components used with
1260 Linux--including GNU Emacs--were developed specifically for the GNU
1261 project. The GNU project was launched in 1984 to develop a free
1262 complete Unix-like operating system. To reach this goal, we had to
1263 develop whatever system components were not available as freely
1264 redistributable software from some other source.
1266 The GNU project wants users of GNU/Linux systems to be aware of how
1267 these systems relate to the GNU project, because that will help
1268 spread the GNU idea that software should be free--and thus encourage
1269 people to write more free software. See the file LINUX-GNU in this
1270 directory for more explanation.
1274 See under "Intel 386".
1278 For installation on MSDOS, see the file INSTALL (search for `MSDOG',
1279 near the end of the file). See the "MS-DOS" chapter of the manual
1280 for information about using Emacs on MSDOS.
1283 If you have TCP but not X, you need to edit src/s/sco4.h
1284 to define HAVE_SOCKETS.
1286 If you are using MMDF instead of sendmail, you need to remove
1287 /usr/lib/sendmail or modify lisp/paths.el before compiling.
1288 lisp/paths.el (which is loaded during the build) will attempt to use
1289 sendmail if it exists.
1291 If you are using SMAIL, you need to define the macro
1294 System V rel 0 (usg5.0)
1296 Works, on Vaxes and 3bxxx's.
1297 There are some problems in 18.37 due to shortnames/cccp problems:
1298 use the emacs 17 cpp if you have it.
1300 System V rel 2 (usg5.2)
1302 Works on various machines.
1303 On some (maybe all) machines the library -lPW exists and contains
1304 a version of `alloca'. On these machines, to use it, put
1306 #define LIB_STANDARD -lPW -lc
1307 in the `src/m/MACHINENAME.h' file for the machine.
1309 If you find that the character Meta-DEL makes Emacs crash,
1310 find where function init_sys_modes in sysdep.c sets sg.c_cc[VQUIT]
1311 and make it store 7 there. I have as yet no evidence of whether
1312 this problem, known in HP/UX, exists in other system V versions.
1314 System V rel 2.2 (usg5.2.2)
1316 In 5.2.2 AT&T undid, incompatibly, their previous incompatible
1317 change to the way the nlist library is called. A different s- file
1318 is used to enable the other interface.
1320 They call themselves the right choice--can't they choose?
1322 Emacs version 18 unexec is currently not working properly
1323 on 5.2.2. Nobody knows why yet. A workaround is to define
1324 NO_REMAP. It is not yet known whether this applies to all
1325 machines running 5.2.2.
1327 System V rel 3 (usg5.3)
1329 Some versions of this system support ptys and BSD-style sockets.
1330 On such systems, you should define HAVE_PTYS and HAVE_SOCKETS in config.h.
1332 If you want to link Emacs with shared libraries, define
1333 USG_SHARED_LIBRARIES.
1335 You may have to add ANSI idempotence #-lines to your sys/types.h
1336 file to get Emacs to compile correctly. This may be necessary on
1337 other pre-ANSI systems as well.
1339 On an AT&T 6386WGS using System V Release 3.2 and X11R3, the X support
1340 cannot be made to work. Whether or not the GNU relocating malloc is
1341 used, the symptom is that the first call Emacs makes to sbrk(0) returns
1342 (char *)-1. Sorry, you're stuck with character-only mode. Try
1343 installing Xfree86 to fix this.
1345 System V rel 4.0.3 and 4.0.4 (usg5.4)
1347 Supported, including shared libraries for ELF, but ptys do not work
1348 because TIOCGPGRP fails to work on ptys (but Dell 2.2 seems to have
1349 fixed this). This failure is probably due to a misunderstanding of
1350 the consequences of the POSIX spec: many system designers mistakenly
1351 think that POSIX requires this feature to fail. This is untrue;
1352 ptys are an extension, and POSIX says that extensions *when used*
1353 may change the action of standard facilities in any fashion.
1355 If you get compilation errors about wrong number of
1356 arguments to getpgrp, define GETPGRP_NO_ARG.
1358 The standard C preprocessor may generate xmakefile incorrectly. However,
1359 /lib/cpp will work, so use `make CPP=/lib/cpp'. Standard cpp
1360 seems to work OK under Dell 2.2.
1362 Some versions 3 and earlier of V.4, on the Intel 386 and 860, had
1363 problems in the X11 libraries. These prevent Emacs from working
1364 with X. You can use Emacs with X provided your copy of X is based
1365 on X11 release 4 or newer, or is Dell's 2.2 (which is a 4.0.3).
1366 Unfortunately, the only way you can tell whether your X11 library is
1367 new enough is to try compiling Emacs to use X. If emacs runs, your
1368 X11 library is new enough.
1370 In this context, GSV4 and GSV4i are alternate names for X11R4.
1371 OL2.* is X11R3 based. OL3 is in between X11R3 and X11R4, and may or
1372 may not work, depending on who made the Unix system. If the library
1373 libXol is part of the X distribution, then you have X11R3 and Emacs
1376 Most versions of V.4 support sockets. If `/usr/lib/libsocket.so'
1377 exists, your system supports them. If yours does not, you must add
1378 #undef HAVE_SOCKETS in config.h, after the inclusion of s-usg5-4.h.
1379 (Any system that supports Internet should implement sockets.)
1383 Recent versions of Ultrix appear to support the features of Berkeley 4.3.
1384 Ultrix was at the BSD 4.2 level for a long time after BSD 4.3 came out.
1386 Ultrix 3.0 has incompatibilities in its X library if you have the
1387 Ultrix version of X (UWS version 2.0). To solve them, you need to
1388 prevent XvmsAlloc.o in Xlib from being used. Israel Pinkas says:
1390 I added the following lines to config.h after the X defines:
1392 #if defined(ultrix) && defined(X11)
1393 #define OBJECTS_SYSTEM calloc.o
1396 Then I ran the following:
1398 ar x /usr/lib/libc.a calloc.o
1400 The problem is said to be gone in UWS version 2.1.
1402 Uniplus 5.2 (unipl5.2)
1404 Works, on Dual machines at least.
1408 Richard Levitte <levitte@e.kth.se> distributes a set of patches to
1409 Emacs 18.59 to make it work nicely under VMS. Emacs 19 probably
1410 won't work very well, or even compile. Levitte is working on a
1411 port, so these problems should be fixed in the near future.
1413 Note that Emacs for VMS is usually distributed in a special VMS
1414 distribution. See the file ../vms/VMSINSTALL for info on moving
1415 Unix distributions to VMS, and other VMS-related topics.
1417 Windows NT/95/98/ME/2000
1419 For installation on all versions of the MS-Windows platform, see the
1424 Should work in 18.50, but you will need to edit the files
1425 `lib-src/Makefile' and `src/ymakefile'
1426 (see the comments that mention "Xenix" for what to change.)
1427 Compiling Emacs with -O is said not to work.
1429 If you want Emacs to work with Smail (installed as /usr/bin/smail)
1430 then add the line #define SMAIL to config.h.
1432 The file etc/XENIX suggests some useful things to do to Xenix
1433 to make the Emacs meta key work.
