1 This is a list of the status of GNU Emacs on various machines and systems.
2 Last updated 10 Feb 1992.
4 For each system and machine, we give the configuration name you should
5 pass to the `configure' script to prepare to build Emacs for that
8 The `configure' script uses the configuration name to decide which
9 machine and operating system description files `src/config.h' should
10 include. The machine description files are all in `src/m', and have
11 names similar to, but not identical to, the machine names used in
12 configuration names. The operating system files are all in `src/s',
13 and are named similarly. See the `configure' script if you need to
14 know which configuration names use which machine and operating system
17 If you add support for a new configuration, add a section to this
18 file, and then edit the `configure' script to tell it which
19 configuration name(s) should select your new machine description and
20 system description files.
23 Here are the configurations Emacs is intended to work with, with the
24 corresponding configuration names. You can postpend version numbers
25 to operating system names (i.e. sunos4.1) or architecture names (i.e.
26 hppa1.1). If you leave out the version number, the `configure' script
27 will configure Emacs for the latest version it knows about.
29 Alliant (fx80-alliant-bsd):
31 18.52 works on system version 4. Previous Emacs versions were
32 known to work on previous system versions.
34 If you are using older versions of their operating system, you may
35 need to edit `src/config.h' to use `m/alliant1.h' (on version 1) or
36 `m/alliant.h' (on versions 2 and 3).
38 Alliant FX/2800 (i860-alliant-bsd)
40 Known to work with 18.58 and OS version 2.2, compiler version 1.3.
42 Altos 3068 (m68k-altos-sysv)
44 18.52 is said to work, provided you don't compile unexec.c with -O.
46 Amdahl UTS (580-amdahl-sysv)
48 Small changes for 18.38 were merged in 18.39. It is mostly
49 working, but at last report a bug sometimes causes Emacs to
50 grab very large amounts of memory. No fix or explanation
51 has yet been reported. It may be possible to find this bug
52 if you find which Emacs command it happens within and then
53 run that command with a breakpoint set at malloc.
55 The 5.2u370 compiler is so brain damaged that it is not
56 even worth trying to use it. Success was obtained with the
57 uts native C compiler on uts version 5.2.5.
59 Apollo running Domain (m68k-apollo-bsd)
61 18.52 works, to some extent.
62 Code for dumping Emacs has been written, but we cannot
64 There are reports of bugs in cc -O on this system.
66 In `lib-src/Makefile', don't expect emacsclient and emacsserver to
67 compile. You might want to remove them from your makefile.
69 Supposedly something in dired.c runs into a compiler bug.
70 Paraphrasing the statement should avoid the problem. I have not yet
71 received word as to the exact statement this is.
73 AT&T 3b2, 3b5, 3b15, 3b20 (we32k-att-sysv)
75 Emacs will probably not work with certain kernel constants too small.
77 In param.h CDLIMIT should be at least (1L << 12) in order to allow
78 processes to write up to 2 Mbyte files. If it's too small,
79 you can perhaps fix it using the file `ulimit.hack' in this directory.
81 Note that for V.3.1 and later releases, this parameter is configurable
82 by normal means in /etc/master.d/kernel; examine that file for the
83 symbol CDLIMIT or ULIMIT, and raise it by several powers of 2. Then
84 do normal kernel rebuild things via "cd /boot; mkboot -k KERNEL" and so
85 forth. Do not use ulimit.hack if you have V.3.1 or later.
87 In seg.h NSEGP and STACKSEG should be at least 16 and 4 respectively
88 to allow processes with total size of up to 2Mbytes.
89 However, I'm told it is unlikely this would fail to be true.
91 The MAXMEM may also prevent Emacs from running. The file
92 3B-MAXMEM in this directory explains how to increase MAXMEM.
94 AT&T 7300 or 3b1 (m68k-att-sysv)
96 18.52 seems to work. If you have strange troubles with dumping
97 Emacs, delete the last few lines from `src/m/7300.h' and recompile.
98 These lines are supposed to produce a sharable executable.
100 `src/m/7300.h' defines SHORTNAMES because operating system versions
101 older than 3.5 did not support long symbol names. Version 3.5 does
102 support them, so you can remove the #define SHORTNAMES in that
105 Bull sps7 (m68k-bull-sysv)
107 Changes partially merged in version 19, but some fixes are probably required.
113 Celerity (celerity-celerity-bsd4.2)
115 Version 18.49 works. This configuration name is a hack, because we
116 don't know the processor used by Celerities. If someone
117 who uses a Celerity could get in touch with us, we can teach
118 config.sub a better name for the configuration.
120 Clipper (clipper-???)
122 Version 19 has support for some brand of clipper system. If you
123 have successfully built Emacs 19 on some sort of clipper system, let
124 us know so we can flesh out this entry.
126 Note that the Orion 105 is also a clipper, but some system-related
127 parameters are different.
129 Convex (c1-convex-bsd, c2-convex-bsd, c32-convex-bsd, c34-convex-bsd,
132 18.53 is supposed to work.
134 Cubix QBx/386 (i386-cubix-sysv)
136 Changes merged in 19.1. Systems before 2/A/0 may fail to compile etags.c
137 due to a compiler bug.
139 Cydra 5 (cydra-cydrome-sysv)
141 18.51 worked in one version of their operating system but stopped
142 working in a newer version. This has not been fixed.
144 DECstation (mips-dec-ultrix or mips-dec-osf)
146 Version 19 works under Ultrix.
148 See under Ultrix for problems using X windows on Ultrix.
149 Note that this is a MIPS machine.
151 For Ultrix versions 4.1 or earlier, you may need to define
152 SYSTEM_MALLOC in `src/m/pmax.h', because XvmsAlloc.o in libX11.a seems
153 to insist on defining malloc itself.
155 For Ultrix versions prior to 4.0, you may need to delete
156 the definition of START_FILES from `src/m/pmax.h'.
158 Motorola Delta 147 (m68k-motorola-sysv)
160 Motorola Delta boxes running System V/68 release 3.
161 (tested on sys1147 with SVR3V5). Changes merged in 19.1.
163 Motorola Delta 187 (m88k-motorola-sysv or m88k-motorola-m88kbcs)
165 Machine support added in version 19.
166 HAVE_X_MENU does not work due to lack of insque.
168 Dual running System V (m68k-dual-sysv)
170 As of 17.46, this works except for a few changes
173 Dual running Uniplus (m68k-dual-uniplus)
177 Elxsi 6400 (elxsi-elxsi-sysv)
179 Changes for 12.0 release are in 19.1.
180 Dumping should work now.
182 Encore machine (ns16k-encore-bsd)
184 This machine bizarrely uses 4.2BSD modified to use the COFF format
185 for object files. Works (as of 18.40). For the APC processor you
186 must enable two lines at the end of `src/s/umax.h', which are commented
187 out in the file as distributed.
189 WARNING: If you compile Emacs with the "-O" compiler switch, you
190 must also use the "-q enter_exits" switch so that all functions have
191 stack frames. Otherwise routines that call `alloca' all lose.
193 A kernel bug in some system versions causes input characters to be lost
196 GEC 63 (local-gec63-usg5.2)
198 Changes are partially merged in version 18, but certainly require
199 more work. Let us know if you get this working, and we'll give it a
200 real configuration name.
202 Gould Power Node (pn-gould-bsd4.2 or pn-gould-bsd4.3)
204 18.36 worked on versions 1.2 and 2.0 of the operating system.
206 On UTX/32 2.0, use pn-gould-bsd4.3.
208 On UTX/32 1.2 and UTX/32S 1.0, use pn-gould-bsd4.2 and note that
209 compiling `lib-src/sorted-doc' tickles a compiler bug: remove the -g
210 flag to cc in the makefile.
212 UTX/32 1.3 has a bug in the bcopy library routine. Fix it by
213 #undef BSTRING in `src/m/gould.h'.
215 Version 19 incorporates support for releases 2.1 and later of UTX/32.
216 A site running a pre-release of 2.1 should #define RELEASE2_1 in config.h.
218 Gould NP1 (np1-gould-bsd)
220 Version 19 supposedly works.
222 Honeywell XPS100 (xps100-honeywell-sysv)
224 Config file added in version 19.
226 HP 9000 series 200 or 300 (m68k-hp-bsd or m68k-hp-hpux7.)
228 Version 19 works under BSD.
230 These machines are 68000-series CPUs running HP-UX
231 (a derivative of sysV with some BSD features) or BSD 4.3 ported by Utah.
232 The operating system suffix determines which system Emacs is built for.
234 Series 200 HPUX runs Emacs only if it has the "HP-UX upgrade".
236 If you are running HP-UX release 8.0 or later, you need the optional
237 "C/ANSI C" software in order to build Emacs (older releases of HP-UX
238 do not require any special software). If the file "/etc/filesets/C"
239 exists on your machine, you have this software, otherwise you do not.
241 Note that HP has used two incompatible assembler syntaxes,
242 and has recently changed the format of C function frames.
243 `src/crt0.c' and `src/alloca.s' have been conditionalised for the new
244 assembler and new function-entry sequence. You may need to define
245 OLD_HP_ASSEMBLER if you are using an older hpux version. If you
246 have an official (bought from HP) series 300 machine you have
247 the new assembler. Kernels that are 5.+ or later have new
248 assembler. A Series 200 that has been upgraded to a 68010
249 processor and a 5.+ kernel has the new compiler.
251 Define C_SWITCH_MACHINE to be +X to make a version of Emacs that
252 runs on both 68010 and 68020 based hp-ux's.
254 Define HPUX_68010 if you are using the new assembler, for
255 a system that has a 68010 without a 68881. This is to say,
256 a s200 (upgraded) or s310.
258 Define the symbol HPUX_NET if you have the optional network features
259 that include the `netunam' system call. This is refered to as
260 Network Services (NS/9000) in HP literature.
262 HP 9000 series 500: not supported.
264 The series 500 has a seriously incompatible memory architecture
265 which relocates data in memory during execution of a program,
266 and support for it would be difficult to implement.
268 HP 9000 series 800 (Spectrum) (hppa1.0-hp-hpux)
270 These files support HP's Precision Architecture machines
271 running HP-UX. It has been moderately tested on the Series
274 If you are running HP-UX release 8.0 or later, you need the optional
275 "C/ANSI C" software in order to build Emacs (older releases of HP-UX
276 do not require any special software). If the file "/etc/filesets/C"
277 exists on your machine, you have this software, otherwise you do not.
279 High Level Hardware Orion (orion-highlevel-bsd)
281 This is the original microprogrammed hardware.
282 Machine description file ought to work.
284 High Level Hardware Orion 1/05 (clipper-highlevel-bsd)
286 Changes merged in 18.52. This is the one with the Clipper cpu.
287 Note that systems which lack NFS need LOAD_AVE_TYPE changed to `double'.
289 C compiler has a bug; it loops compiling eval.c.
290 Compile it by hand without optimization.
292 IBM PS/2 (i386-ibm-aix1.1 or i386-ibm-aix1.2)
294 Changes merged in version 19. You may need to copy
295 /usr/lib/samples/hft/hftctl.c to the Emacs src directory.
297 i386-ibm-aix1.1 may not work with certain new X window managers, and
300 IBM RS/6000 (rs6000-ibm-aix)
302 Changes merged in version 19. Currently the configuration
303 does not actually depend on the version of AIX.
305 Compiling with -O using the IBM compiler has been known
306 to make Emacs work incorrectly.
308 IBM RT/PC (romp-ibm-bsd or romp-ibm-aix)
310 18.52 works on both operating systems.
311 Use romp-ibm-bsd for the 4.2-like system and romp-ibm-aix for AIX.
313 On BSD, if you have trouble, try compiling with a different compiler.
315 On AIX, the file /usr/lib/samples/hft/hftctl.c must be compiled into
316 hftctl.o, with this result left in the src directory (hftctl.c is
317 part of the standard AIX distribution).
319 window.c must not be compiled with -O on AIX.
321 Integrated Solutions `Optimum V' (m68k-isi-bsd4.2 or -bsd4.3)
323 18.52 said to work on some sort of ISI machine.
324 Version 18.45 worked (running on a Optimum V (VME bus, 68020)
325 BSD 4.2 (3.05e) system). 18.42 is reported to work on
326 a Qbus 68010 system. Has not been tried on `WorkStation' `Cluster
327 Compute Node' `Cluster WorkStation' or `Server Node' (Love the
330 Compilation with -O is rumored to break something.
332 On recent system versions, you may need to undefine the macro UMAX
333 in `lib-src/loadst.c' and `src/getpagesize.h'. They stupidly defined this
334 in a system header file, which confuses Emacs (which thinks that UMAX
335 indicates the Umax operating system).
337 Intel 386 (i386-unknown-isc, i386-unknown-esix, i386-unknown-xenix,
338 i386-intsys-sysv, i386-unknown-sysv5.2.2, i386-unknown-sysv5.3,
339 and i386-unknown-bsd4.2)
341 18.58 should support a wide variety of operating systems.
342 Make sure to use i386-unknown-isc2.2 for Interactive 386/ix version
344 Use i386-unknown-esix for Esix.
345 Use i386-intsys-sysv for Integrated Solutions 386 machines.
346 It may also be correct for Microport systems.
347 It isn't clear what to do on an SCO system. The system's C
348 preprocessor doesn't seem to handle the src subdirectory's Make
349 trickery, so you will probably need to install the GNU C preprocessor.
351 If you are using Xenix, see notes above under Xenix.
353 Some sysV.3 systems seem to have bugs in `opendir';
354 for them, alter `config.h' to define NONSYSTEM_DIR_LIBRARY
355 and undefine SYSV_SYSTEM_DIR.
357 If you use optimization on V.3, you may need the option -W2,'-y 0'
358 to prevent certain faulty optimization.
360 On 386/ix, to link with shared libraries, add #define USG_SHARED_LIBRARIES
363 There is no consistency in the handling of certain system header files
366 Some versions have sys/sioctl.h, and require it in sysdep.c.
367 But some versions do not have sys/sioctl.h.
368 For a given version of the system, this may depend on whether you have
369 X Windows or TCP/IP. Define or undefine NO_SIOCTL_H in config.h
370 according to whether you have the file.
372 Likewise, some versions have been known to need sys/ttold.h, sys/stream.h,
373 and sys/ptem.h included in sysdep.c. If your system has these files,
374 try defining NEED_PTEM_H in config.h if you have trouble without it.
376 You may find that adding -I/usr/X/include or -I/usr/netinclude or both
377 to CFLAGS avoids compilation errors on certain systems.
379 Some versions convince sysdep.c to try to use `struct tchars'
380 but define `struct tc' instead; add `#define tchars tc'
381 to config.h to solve this problem.
383 Iris 2500 and Iris 2500 Turbo (m68k-sgi-iris3.5 or m68k-sgi-iris3.6)
385 Version 18 said to work; use m68k-sgi-iris3.5 for system version 2.5
386 and m68k-sgi-iris3.6 for system version 3.6.
387 Note that the 3030 is the same as the Iris 2500 Turbo.
389 Iris 4D (mips-sgi-irix3.3 or mips-sgi-irix4.0)
391 18.58 is known to work on Silicon Graphics 4D series machines
392 with IRIX 3.3 or IRIX 4.0. Version 19 should support the
393 ANSI C compiler version 3.10.
395 Most irix3.3 systems do not have an ANSI C compiler, but a few do.
396 If you are using the ANSI C compiler, you may need to add
397 #define C_SWITCH_MACHINE -cckr
400 There is a bug in IRIX that can sometimes leave ptys owned by
401 root with a permission of 622. This causes malfunctions in use
402 of subprocesses of Emacs. This may be fixed in IRIX 4.0.5.
406 We are boycotting Apple because of Apple's efforts to take away
407 our freedom to write compatible imitations of existing software.
408 If you value your freedom to write such programs, we urge you
409 not to buy from Apple, not to develop software for Apple, and
410 certainly not to accept a job with Apple.
412 See the file APPLE in this directory for more information.
414 Masscomp (m68k-masscomp-rtu)
416 18.36 worked on a 5500DP running RTU v3.1a and compiler version 3.2
417 with minor fixes that are included in 18.37. However, bizarre behavior
418 was reported for 18.36 on a Masscomp (model and version unknown but probably
419 a 68020 system). The report sounds like a compiler bug.
421 A compiler bug affecting statements like
422 unsigned char k; unsigned char *p;... x = p[k];
423 has been reported for "C version 1.2 under RTU 3.1". We do not wish
424 to take the time to install the numerous workarounds required to
425 compensate for this bug; go complain to Masscomp.
427 For RTU version 3.1, define FIRST_PTY_LETTER to be 'p' in `src/s/rtu.h'
428 (or #undef and redefine it in config.h) so that ptys will be used.
430 GNU Emacs is said to have no chance of compiling on RTU versions
433 Megatest (m68k-megatest-bsd)
435 Emacs 15 worked; do not have any reports about Emacs 16 or 17
436 but any new bugs are probably not difficult.
438 Mips (mips-mips-riscos, mips-mips-riscos4.0, or mips-mips-bsd)
440 Changes merged in 18.39. Some fixes in 18.56.
442 Use mips-mips-riscos4.0 for RISCOS version 4.
443 Use mips-mips-bsd with the BSD world.
445 Note that the proper configuration names for DECstations are
446 mips-dec-ultrix and mips-dec-osf.
448 If you are compiling with GCC, then you must run fixincludes;
449 the alternative of using -traditional won't work because
450 the definition of SIGN_EXTEND_CHAR uses the keyword `signed'.
452 If the SYSV world is the default, then you probably need the following
453 line in etc/Makefile:
455 CFLAGS= -g -systype bsd43
457 Some operating systems on MIPS machines give SIGTRAP for division by
458 zero instead of the usual signals. The only real solution is to fix
459 the system to give a proper signal.
461 In the meantime, you can change init_data in data.c if you wish.
462 Change it to handle SIGTRAP as well as SIGFPE. But this will have a
463 great disadvantage: you will not be able to run Emacs under a
464 debugger. I think crashing on division by zero is a lesser problem.
466 National Semiconductor 32000 (ns32k-ns-genix)
468 This is for a complete machine from National Semiconductor,
469 running Genix. Changes merged in version 19.
471 NCR Tower 32 (m68k-ncr-sysv2 or m68k-ncr-sysv3)
473 If you are running System V release 2, use m68k-ncr-sysv2.
474 If you are running System V release 3, use m68k-ncr-sysv3.
476 These both work as of 18.56. If you change `src/ymakefile' so that
477 CFLAGS includes C_OPTIMIZE_SWITCH rather than C_DEBUG_SWITCH, check
478 out the comments in `src/m/tower32.h' (for System V release 2) or
479 `src/m/tower32v3.h' (for System V release 3) about this.
481 There is a report that compilation with -O did not work with 18.54
482 under System V release 2.
484 Nixdorf Targon 31 (m68k-nixdorf-sysv)
486 Machine description file for version 17 is included in 18
487 but whether it works is not known.
488 `src/unexec.c' bombs if compiled with -O.
489 Note that the "Targon 35" is really a Pyramid.
491 Nu (TI or LMI) (m68k-nu-sysv)
493 Version 18 is believed to work.
495 Plexus (m68k-plexus-sysv)
499 Pmax (DEC Mips) (mips-dec-ultrix or mips-dec-osf1)
501 See under DECstation, above.
503 Prime EXL (i386-prime-sysv)
505 Minor changes merged in 19.1.
507 Pyramid (pyramid-pyramid-bsd)
509 You need to build Emacs in the Berkeley universe with
510 the `ucb' command, as in `ucb make' or `ucb build-install'.
512 In OSx 4.0, it seems necessary to add the following two lines
513 to `src/m/pyramid.h':
514 #define _longjmp longjmp
515 #define _setjmp setjmp
517 In Pyramid system 2.5 there has been a compiler bug making
518 Emacs crash just after screen-splitting with Qnil containing 0.
519 A compiler that fixes this is Pyramid customer number 8494,
520 internal number 1923.
522 Some versions of the pyramid compiler get fatal
523 errors when the -gx compiler switch is used; if this
524 happens to you, change `src/m/pyramid.h' to define
525 C_DEBUG_SWITCH with an empty definition.
527 Some old system versions may require you to define PYRAMID_OLD
528 in when alloca.s is preprocessed, in order to define _longjmp and _setjmp.
530 Sequent Balance (ns32k-sequent-bsd4.2 or ns32k-sequent-bsd4.3)
532 Emacs 18.51 should work on system version 3.0. 18.52 is said to work.
533 Delete some lines at the end of `src/m/sequent.h' for earlier system
536 Sequent Symmetry (i386-sequent-bsd)
538 Emacs 19 should work.
540 SONY News (m68k-sony-bsd4.2 or m68k-sony-bsd4.3)
543 Use m68k-sony-bsd4.3 for system release 3.
545 SONY News 3000 series (RISC NEWS) (mips-sony-bsd)
547 Works, as of 18.56. Note that this is a MIPS architecture machine.
549 Some versions of the operating system give SIGTRAP for division by zero
550 instead of the usual signals. This causes division by zero
551 to make Emacs crash. The system should be fixed to give the proper signal.
552 Changing Emacs is not a proper solution, because it would prevent
553 Emacs from working under any debugger. But you can change init_data
554 in data.c if you wish.
556 Stardent 1500 or 3000
560 Stride (m68k-stride-sysv)
562 Works (most recent news for 18.30) on their release 2.0.
563 For release 2.2, see the end of `src/m/stride.h'.
564 It may be possible to run on their V.1 system but changes
565 in the s- file would be needed.
567 Sun 1, 2 and 3 (m68k-sun-sunos, sparc-sun-sunos, i386-sun-sunos)
569 It's important to include the SunOS version number in the
570 configuration name. For example, for SunOS release 4.0 on a Sun 3,
571 use `m68k-sun-sunos4.0'; for SunOS release 4.1 on a Sparc, use
572 `sparc-sun-sunos4.1'.
574 Use `m68k' for the 68000-based Sun boxes, `sparc' for Sparcstations,
575 and `i386' for Sun Roadrunners.
577 There are three machine files for the different versions of SunOS
578 that run on the Motorola 68000 processors. All are derived from
579 Berkeley 4.2. Emacs 17 has run on all of them.
581 See the file etc/SUNBUG for how to solve problems caused by
582 bugs in the "export" version of SunOS 4.
584 If you have trouble using open-network-stream, get the
585 distribution of `bind' (the BSD name-server), build libresolv.a,
586 and link Emacs with -lresolv. This problem is due to obsolete
587 software in the nonshared standard library.
589 If you want to use SunWindows, define HAVE_SUN_WINDOWS
590 in config.h to enable a special interface called `emacstool'.
591 The definition must *precede* the #include "machine.h".
592 System version 3.2 is required for this facility to work.
594 We recommend that you instead use the X window system, which
595 has technical advantages, is an industry standard, and is also
598 If you are compiling for X windows, and the X window library was
599 compiled to use the 68881, then you must edit config.h according
600 the comments at the end of `src/m/sun3.h'.
602 Note that Emacs on a Sun is not really as big as it looks.
603 As dumped, it includes around 200k of zeros between the
604 original text section and the original data section
605 (now remapped as part of the text). These are never
608 To build a single Emacs that will run on Sun 2 and Sun 3
609 HARDWARE, just build it on the Sun 2.
611 Changes for the Sparc architecture were merged in 18.50. Some
612 people say optimizing compilation does not work; some say that -O2
613 (whatever that is) works perhaps with a small change.
615 Changes for the Roadrunner architecture were merged in 18.51.
617 Tadpole 68K (m68k-tadpole-sysv)
619 Changes merged in 19.1.
621 You may need to edit Makefile to change the variables LIBDIR and
622 BINDIR from /usr/local to /usr/contrib.
624 To give movemail access to /usr/mail, you may need to execute
626 chmod 2755 etc/movemail; chgrp mail etc/movemail
628 Tahoe (tahoe-tahoe-bsd4.2 or tahoe-tahoe-bsd4.3)
630 18.52 known to work on some Tahoes, but a compiler bug intervenes
631 on others. Some Emacs versions have worked in Unisys 1r4
632 (not in 1r3) and CCI I.21.
634 If you have trouble compiling `lib-src/loadst.c', turn off the definition
635 of DKSTAT_HEADER_FILE in `src/m/tahoe.h'.
637 Tandem Integrity S2 (mips-tandem-sysv)
639 Changes merged in 18.56 but subprocess support is turned off.
640 You will probably want to see if you can make subprocesses work.
642 You must edit `lib-src/Makefile' to define LOADLIBES = -mld.
644 Tektronix 16000 box (6130?) (ns16k-tektronix-bsd)
648 Tektronix 4300 (m68k-tektronix-bsd)
650 Emacs 18.51 should work.
652 Titan P2 or P3 (titan-titan-sysv)
654 Changes probably merged in version 19.
656 Ustation E30 (SS5E) (m68k-unisys-unipl)
658 Changes merged in 18.52; don't know whether they work.
660 Vaxen running Berkeley Unix (vax-dec-bsd4.1, vax-dec-bsd4.2, vax-dec-bsd4.3),
661 Ultrix (vax-dec-ultrix),
662 System V (vax-dec-sysv0, vax-dec-sysv2), or
667 See under Ultrix for problems using X windows on Ultrix (vax-dec-ultrix).
669 18.27 works on System V rel 2 (vax-dec-sysv2).
671 18.36 works on System V rel 0 (vax-dec-sysv0).
673 18.36 is believed to work on VMS. Addition of features is necessary
674 to make this Emacs version more usable.
676 Whitechapel MG1 (ns16k-whitechapel-?)
678 May work. Supposedly no changes were needed except in `src/m/mg1.h'
679 file. I do not know what Unix version runs on them.
681 Wicat (m68k-wicat-sysv)
683 Changes merged as of 18.6; whether they work is unknown.
684 See comments in `src/m/wicat.h' for things you should change
685 depending on the system and compiler version you have.
687 Here is a summary of the systems supported:
689 Berkeley 4.1 (bsd4.1)
693 Berkeley 4.2 (bsd4.2)
695 Works on several machines.
697 Berkeley 4.3 (bsd4.3)
699 Works, on Vaxes at least.
703 See under "Intel 386".
705 System V rel 0 (usg5.0)
707 Works, on Vaxes and 3bxxx's.
708 There are some problems in 18.37 due to shortnames/cccp problems:
709 use the emacs 17 cpp if you have it.
711 System V rel 2 (usg5.2)
713 Works on various machines.
714 On some (maybe all) machines the library -lPW exists and contains
715 a version of `alloca'. On these machines, to use it, put
717 #define LIB_STANDARD -lPW -lc
718 in the `src/m/MACHINENAME.h' file for the machine.
720 If you find that the character Meta-DEL makes Emacs crash,
721 find where function init_sys_modes in sysdep.c sets sg.c_cc[VQUIT]
722 and make it store 7 there. I have as yet no evidence of whether
723 this problem, known in HP-UX, exists in other system V versions.
725 System V rel 2.2 (usg5.2.2)
727 In 5.2.2 AT&T undid, incompatibly, their previous incompatible
728 change to the way the nlist library is called. A different s- file
729 is used to enable the other interface.
731 They call themselves the right choice--can't they choose?
733 Emacs version 18 unexec is currently not working properly
734 on 5.2.2. Nobody knows why yet. A workaround is to define
735 NO_REMAP. It is not yet known whether this applies to all
736 machines running 5.2.2.
738 System V rel 3 (usg5.3)
740 Some versions of this system support ptys and BSD-style sockets.
741 On such systems, you should define HAVE_PTYS and HAVE_SOCKETS in config.h.
743 If you want to link Emacs with shared libraries, define
744 USG_SHARED_LIBRARIES.
746 You may have to add ANSI idempotence #-lines to your sys/types.h
747 file to get Emacs to compile correctly. This may be necessary on
748 other pre-ANSI systems as well.
750 On an AT&T 6386WGS using System V Release 3.2 and X11R3, the X support
751 cannot be made to work. Whether or not the GNU relocating malloc is
752 used, the symptom is that the first call Emacs makes to sbrk(0) returns
753 (char *)-1. Sorry, you're stuck with character-only mode. Try
754 installing Xfree86 to fix this.
756 System V rel 4.0.3 and 4.0.4 (usg5.4)
758 Supported, including shared libraries for ELF, but ptys do not work
759 because TIOCGPGRP fails to work on ptys (but Dell 2.2 seems to have
760 fixed this). This failure is probably due to a misunderstanding of
761 the consequences of the POSIX spec: many system designers mistakenly
762 think that POSIX requires this feature to fail. This is untrue;
763 ptys are an extension, and POSIX says that extensions *when used*
764 may change the action of standard facilities in any fashion.
766 The standard C preprocessor may generate xmakefile incorrectly. However,
767 /lib/cpp will work, so use `make CPP=/lib/cpp'. Standard cpp
768 seems to work OK under Dell 2.2.
770 Some versions 3 and earlier of V.4, on the Intel 386 and 860, had
771 problems in the X11 libraries. These prevent Emacs from working
772 with X. You can use Emacs with X provided your copy of X is based
773 on X11 release 4 or newer, or is Dell's 2.2 (which is a 4.0.3).
774 Unfortunately, the only way you can tell whether your X11 library is
775 new enough is to try compiling Emacs to use X. If emacs runs, your
776 X11 library is new enough.
778 In this context, GSV4 and GSV4i are alternate names for X11R4.
779 OL2.* is X11R3 based. OL3 is in between X11R3 and X11R4, and may or
780 may not work, depending on who made the Unix system. If the library
781 libXol is part of the X distribution, then you have X11R3 and Emacs
784 Most versions of V.4 support sockets. If `/usr/lib/libsocket.so'
785 exists, your system supports them. If yours does not, you must add
786 #undef HAVE_SOCKETS in config.h, after the inclusion of s-usg5-4.h.
787 (Any system that supports Internet should implement sockets.)
791 Recent versions of Ultrix appear to support the features of Berkeley 4.3.
792 Ultrix was at the BSD 4.2 level for a long time after BSD 4.3 came out.
794 Ultrix 3.0 has incompatibilities in its X library if you have the
795 Ultrix version of X (UWS version 2.0). To solve them, you need to
796 prevent XvmsAlloc.o in Xlib from being used. Israel Pinkas says:
798 I added the following lines to config.h after the X defines:
800 #if defined(ultrix) && defined(X11)
801 #define OBJECTS_SYSTEM calloc.o
804 Then I ran the following:
806 ar x /usr/lib/libc.a calloc.o
808 The problem is said to be gone in UWS version 2.1.
810 Uniplus 5.2 (unipl5.2)
812 Works, on Dual machines at least.
816 Works except for certain features (directory listing, dired,
817 sending and receiving mail) that use synchronous subprocesses.
818 We need people to write alternative implementations of these
821 The config file s/vms5-5.h may be right for some earlier versions;
822 please let us know what happens when you try it in VMS versions 5.0
825 Note that Emacs for VMS is usually distributed in a special VMS
826 distribution. See the file ../vms/VMSINSTALL for info on moving
827 Unix distributions to VMS, and other VMS-related topics.
831 Should work in 18.50, but you will need to edit the files
832 `lib-src/Makefile' and `src/ymakefile'
833 (see the comments that mention "Xenix" for what to change.)
834 Compiling Emacs with -O is said not to work.
836 If you want Emacs to work with Smail (installed as /usr/bin/smail)
837 then add the line #define SMAIL to config.h.
839 The file etc/XENIX suggests some useful things to do to Xenix
840 to make the Emacs meta key work.
