1.1 root 1: This is a list of the status of GNU Emacs on various machines and systems.
2: Last updated 18 Oct 1992.
3:
4: Systems:
5: For each type of system, the name of the appropriate s- header file
6: is given.
7:
8: Berkeley 4.1 (s-bsd4-1.h)
9:
10: Works on vaxes.
11:
12: Berkeley 4.2 (s-bsd4-2.h)
13:
14: Works on several machines.
15:
16: Berkeley 4.3 (s-bsd4-3.h)
17:
18: Works, on Vaxes at least.
19:
20: Microport
21:
22: See under "Intel 386".
23:
24: Solaris (s-sol2.h)
25:
26: Changes merged, and may work.
27:
28: System V rel 0 (s-usg5-0.h)
29:
30: Works, on Vaxes and 3bxxx's.
31: There are some problems in 18.37 due to shortnames/cccp problems:
32: use the emacs 17 cpp if you have it.
33:
34: System V rel 2 (s-usg5-2.h)
35:
36: Works on various machines.
37: On some (maybe all) machines the library -lPW exists and contains
38: a version of `alloca'. On these machines, to use it, put
39: #define HAVE_ALLOCA
40: #define LIB_STANDARD -lPW -lc
41: in the m-...h file for the machine.
42:
43: If you find that the character Meta-DEL makes Emacs crash,
44: find where function init_sys_modes in sysdep.c sets sg.c_cc[VQUIT]
45: and make it store 7 there. I have as yet no evidence of whether
46: this problem, known in HP-UX, exists in other system V versions.
47:
48: If you are compiling to work with X11 release 4, you may need
49: to define HAVE_RANDOM in config.h.
50:
51: System V rel 2.2 (s-usg5-2-2.h)
52:
53: In 5.2.2 AT&T undid, incompatibly, their previous incompatible
54: change to the way the nlist library is called. A different s- file
55: is used to enable the other interface.
56:
57: They call themselves the right choice--can't they choose?
58:
59: Emacs version 18 unexec is currently not working properly
60: on 5.2.2. Nobody knows why yet. A workaround is to define
61: NO_REMAP. It is not yet known whether this applies to all
62: machines running 5.2.2.
63:
64: If you are compiling to work with X11 release 4, you may need
65: to define HAVE_RANDOM in config.h.
66:
67: System V rel 3 (s-usg5-3.h)
68:
69: Some versions of this system support ptys and BSD-style sockets.
70: On such systems, you should define HAVE_PTYS and HAVE_SOCKETS in config.h.
71:
72: If you are compiling to work with X11 release 4, you may need
73: to define HAVE_RANDOM in config.h.
74:
75: If you want to link Emacs with shared libraries, define
76: USG_SHARED_LIBRARIES.
77:
78: System V rel 4 (s-usg5-4.h)
79:
80: Supported, including shared libraries for ELF. pty's work now.
81:
82: The standard C preprocessor generates xmakefile incorrectly. However,
83: /lib/cpp will work, so use `make CPP=/lib/cpp' in the `src' subdirectory.
84:
85: Versions 3 and earlier of V.4, on the Intel 386 and 860, had
86: problems in the X11 libraries. These prevent Emacs from working
87: with X. You can use Emacs with X provided your copy of X is based
88: on X11 release 4 or newer. Unfortunately, the only way you can tell
89: for certain whether your X11 library is new enough is to try
90: compiling Emacs to use X. If xemacs runs, your X11 library is new
91: enough.
92:
93: In this context, GSV4 and GSV4i are alternate names for X11R4.
94: OL2.* is X11R3 based. OL3 is in between X11R3 and X11R4, and may or
95: may not work, depending on who made the Unix system. If the library
96: libXol is part of the X distribution, then you have X11R3 and Emacs
97: won't work with X.
98:
99: Most versions of V.4 support sockets. If `/usr/lib/libsocket.so'
100: exists, your system supports them. If yours does not, you must add
101: #undef HAVE_SOCKETS in config.h, aftern the inclusion of s-usg5-4.h.
102: (Any system that supports Internet should implement sockets.)
103:
104: Ultrix (s-bsd4-3.h)
105:
106: Recent versions of Ultrix appear to support the features of Berkeley 4.3.
107: Ultrix was at the BSD 4.2 level for a long time after BSD 4.3 came out.
108:
109: Ultrix 3.0 has incompatibilities in its X library if you have the
110: Ultrix version of X (UWS version 2.0). To solve them, you need to
111: prevent XvmsAlloc.o in Xlib from being used. Israel Pinkas says:
112:
113: I added the following lines to config.h after the X defines:
114:
115: #if defined(ultrix) && defined(X11)
116: #define OBJECTS_SYSTEM calloc.o
117: #endif
118:
119: Then I ran the following:
120:
121: ar x /usr/lib/libc.a calloc.o
122:
123: The problem is said to be gone in UWS version 2.1.
124:
125: Ultrix 4.1 has moved the file X11/X10.h into mit/X11/X10.h.
126:
127: Uniplus 5.2 (s-unipl5-2.h)
128:
129: Works, on Dual machines at least.
130:
131: VMS (s-vms4-0.h, s-vms4-2.h, s-vms4-4.h, s-vms5-5.h)
132:
133: Works except for certain features (directory listing, dired,
134: sending and receiving mail) that use synchronous subprocesses.
135: (These will work in Emacs 19.)
136: s-vms5-5.h may be right for some earlier versions; please let us know
137: what happens when you try it in VMS versions 5.0 thru 5.4.
138:
139: Note that Emacs for VMS is usually distributed in a special
140: VMS distribution. See the file ../VMSINSTALL for info on moving
141: Unix distributions to VMS, and other VMS-related topics.
142:
143: Xenix
144:
145: Should work in 18.50, but you will need to edit the files
146: etc/Makefile and src/ymakefile
147: (see the comments that mention "Xenix" for what to change.)
148: Compiling Emacs with -O is said not to work.
149:
150: If you want Emacs to work with Smail (installed as /usr/bin/smail)
151: then add the line #define SMAIL to config.h.
152:
153: The file etc/XENIX suggests some useful things to do to Xenix
154: to make the Emacs meta key work.
155:
156: Machines:
157: For each type of machine, the names of the m- and s- header files
158: are given.
159:
160: Alliant FX/80 (m-alliant4.h or m-alliant.h or m-alliant1.h;
161: s-bsd4-2.h or s-bsd4-3.h)
162:
163: There are reports of bugs in the Alliant compiler
164: that prevent compiling Emacs 18.57.
165: No word on how to get around them. Perhaps using GCC will work.
166: A work-around is installed in src/dispnew.c in 18.58 for a compiler bug.
167:
168: 18.52 worked on system version 4. Previous Emacs versions were
169: known to work on previous system versions.
170:
171: Use m-alliant1.h on version 1 of their operating system
172: and use m-alliant.h on version 2 or 3.
173: Use m-alliant4.h on version 4 and above.
174:
175: Use s-bsd4-3.h with system version 5 and above.
176:
177: Alliant FX/2800 (m-all2800.h; s-bsd4-3.h)
178:
179: Known to work with 18.58 and OS version 2.2, compiler version 1.3.
180:
181: Altos 3068 (m-altos.h; s-usg5-2.h)
182:
183: 18.52 is said to work, provided you don't compile unexec.c with -O.
184:
185: Amdahl UTS (m-amdahl.h; s-usg5-3.h)
186:
187: Support for a newer system version, and X Windows, merged in 18.58.
188: (Some people report that s-usg5-2.h worked better than s-usg5-3.h
189: for 18.57.)
190:
191: The 5.2u370 compiler is so brain damaged that it is not
192: even worth trying to use it. Success was obtained with the
193: uts native C compiler on uts version 5.2.5.
194:
195: Apollo running Domain (m-apollo.h; s-bsd4-2.h)
196:
197: 18.52 works, to some extent.
198: Code for dumping Emacs has been written, but we cannot
199: distribute it yet.
200: There are reports of bugs in cc -O on this system.
201:
202: In etc/Makefile, don't expect emacsclient and server to
203: compile. You might want to remove them from your makefile.
204:
205: Supposedly something in dired.c runs into a compiler bug.
206: Paraphrasing the statement should avoid the problem.
207: I havenot yet received word as to the exact statement this is.
208:
209: AT&T 3b2, 3b5, 3b15, 3b20 (m-att3b.h; s-usg5-2-2.h)
210:
211: Emacs will probably not work with certain kernel constants too small.
212:
213: In param.h CDLIMIT should be at least (1L << 12) in order to allow
214: processes to write up to 2 Mbyte files. If it's too small,
215: you can perhaps fix it using the file `ulimit.hack' in this directory.
216:
217: Note that for V.3.1 and later releases, this parameter is configurable
218: by normal means in /etc/master.d/kernel; examine that file for the
219: symbol CDLIMIT or ULIMIT, and raise it by several powers of 2. Then
220: do normal kernel rebuild things via "cd /boot; mkboot -k KERNEL" and so
221: forth. Do not use ulimit.hack if you have V.3.1 or later.
222:
223: In seg.h NSEGP and STACKSEG should be at least 16 and 4 respectively
224: to allow processes with total size of up to 2Mbytes.
225: However, I'm told it is unlikely this would fail to be true.
226:
227: The MAXMEM may also prevent Emacs from running. The file
228: 3B-MAXMEM in this directory explains how to increase MAXMEM.
229:
230: AT&T 7300 or 3b1 (m-7300.h; s-usg5-2-2.h)
231:
232: 18.52 seems to work. If you have strange troubles with dumping Emacs,
233: delete the last few lines from m-7300.h and recompile. These lines
234: are supposed to produce a sharable executable.
235:
236: m-7300.h defines SHORTNAMES because operating system versions
237: older than 3.5 did not support long symbol names. Version 3.5 does
238: support them, so you can remove the #define SHORTNAMES in that version.
239:
240: Aviion (m-aviion.h; s-dgux.h)
241:
242: Changes merged in 18.58.
243:
244: Bull DPX/2 models 2nn or 3nn (m-dpx2-200.h or m-dpx2-300.h; s-usg5-3.h)
245:
246: Should work in 18.58 except that there is a report of
247: Emacs terminating mysteriously if run in the background
248: using its own X window and the invoking process
249: terminates.
250:
251: Be sure to read m-dpx2.h for instructions as to how to deal
252: with optional packages such as INET and X Windows.
253:
254: CCI 5/32, 6/32
255:
256: See "Tahoe".
257:
258: Celerity (m-celerity.h; s-bsd4-2.h)
259:
260: Version 18.49 works.
261:
262: Convex (m-convex.h; s-bsd4-3.h)
263:
264: 18.58 works.
265: Use "make CC='cc -pcc'" to avoid problems creating ymakefile from xmakefile.
266:
267: Cydra 5 (m-cydra5.h; s-usg5-3.h)
268:
269: 18.51 worked in one version of their operating system but stopped
270: working in a newer version. This has not been fixed.
271:
272: Data General
273:
274: See aviion.
275:
276: DECstation (m-pmax.h; s-bsd4-3.h or s-osf1.h)
277:
278: OSF1 support merged in 18.59.
279:
280: See under Ultrix for problems using X windows
281: on Ultrix. Note that this is a MIPS machine.
282: s-bsd4-3.h is said to work ok with Ultrix 4.1.
283:
284: For Ultrix versions prior to 4.0, you may need to delete
285: the definition of START_FILES from m-pmax.h.
286:
287: Dual running System V (m-dual.h; s-usg5-2.h)
288:
289: As of 17.46, this works except for a few changes
290: needed in unexec.c.
291:
292: Dual running Uniplus (m-dual.h; s-unipl5-2.h)
293:
294: Works, as of 17.51.
295:
296: Elxsi 6400 (m-elxsi; s-usg5-2.h)
297:
298: 18.36 required one small change that's installed in 18.38.
299:
300: m-elxsi.h currenty specifies CANNOT_DUMP.
301: The Elxsi can in principle dump, but the necessary changes to
302: unexec, which involve byte-swapping, were too ugly to install.
303: If someone submits simple code that supports dumping on the Elxsi,
304: it can be installed and CANNOT_DUMP can be turned off.
305:
306: Encore machine (m-ns16000.h; s-umax.h)
307:
308: This machine bizarrely uses 4.2BSD modified to use the COFF format
309: for object files. Works (as of 18.40). For the APC processor you
310: must enable two lines at the end of s-umax.h, which are commented
311: out in the file as distributed.
312:
313: WARNING: If you compile Emacs with the "-O" compiler switch, you
314: must also use the "-q enter_exits" switch so that all functions have
315: stack frames. Otherwise routines that call `alloca' all lose.
316:
317: A kernel bug in some system versions causes input characters to be lost
318: occasionally.
319:
320: Encore running MACH.
321:
322: This does not yet work.
323:
324: GEC 93 (m-gec93.h; s-usg5-2.h?)
325:
326: Changes are partially merged in version 18, but
327: certainly require more work.
328:
329: Gould (m-gould.h; s-bsd4-2.h or s-bsd4-3.h)
330:
331: 18.36 worked on versions 1.2 and 2.0 of the operating system.
332:
333: On UTX/32 2.0, use s-bsd4-3.h.
334:
335: On UTX/32 1.2 and UTX/32S 1.0, use s-bsd4-2.h and note that compiling
336: etc/sorted-doc tickles a compiler bug: remove the -g flag to cc in the
337: makefile.
338:
339: UTX/32 1.3 has a bug in the bcopy library routine. Fix it by
340: #undef BSTRING in m-gould.h.
341:
342: HP 9000 series 200 or 300 (m-hp9000s300.h; s-hpux7.h, s-hpux8.h or s-bsd4-3.h)
343:
344: Version 18 works.
345: These machines are 68000-series CPUs running HP-UX
346: (a derivative of sysV with some BSD features) or BSD 4.3 ported by Utah.
347: The choice of s- file determines which system Emacs is built for.
348:
349: If you are running HP-UX release 8.0 or later, you need the optional
350: "C/ANSI C" software in order to build Emacs (older releases of HP-UX
351: do not require any special software). If the file "/etc/filesets/C"
352: exists on your machine, you have this software, otherwise you do not.
353:
354: Series 200 HPUX runs Emacs only if it has the "HP-UX upgrade".
355:
356: The series 500 has a seriously incompatible memory architecture
357: which relocates data in memory during execution of a program,
358: and support for it would be difficult to implement.
359:
360: Note that HP has used two incompatible assembler syntaxes,
361: and has recently changed the format of C function frames.
362: src/crt0.c and src/alloca.s have been conditionalised for the new
363: assembler and new function-entry sequence. You may need to define
364: OLD_HP_ASSEMBLER if you are using an older hpux version. If you
365: have an official (bought from HP) series 300 machine you have
366: the new assembler. Kernels that are 5.+ or later have new
367: assembler. A Series 200 that has been upgraded to a 68010
368: processor and a 5.+ kernel has the new compiler.
369:
370: Define C_SWITCH_MACHINE to be +X to make a version of Emacs that
371: runs on both 68010 and 68020 based hp-ux's.
372:
373: Define HPUX_68010 if you are using the new assembler, for
374: a system that has a 68010 without a 68881. This is to say,
375: a s200 (upgraded) or s310.
376:
377: Define the symbol HPUX_NET if you have the optional network features
378: that include the `netunam' system call. This is refered to as
379: Network Services (NS/9000) in HP literature.
380:
381: If you are compiling to work with X11 release 4, you may need
382: to define HAVE_RANDOM in config.h.
383:
384: HP 9000 series 700 or 800 (Spectrum) (m-hp9000s800.h; s-hpux7.h or s-hpux8.h)
385:
386: These files support HP's Precision Architecture machines
387: running HP-UX. Version 18.58 should work on the 700 and the 800.
388: Use s-hpux7.h for HPUX version 7 or earlier,
389: and s-hpux8.h for HPUX version 8.
390: If you are running HP-UX release 8.0 or later, you need the optional
391: "C/ANSI C" software in order to build Emacs (older releases of HP-UX
392: do not require any special software). If the file "/etc/filesets/C"
393: exists on your machine, you have this software, otherwise you do not.
394:
395: HAVE_X_MENU works, but you may need to modify oldXMenu/Makefile
396: to compile insque.c.
397:
398: If you compile with MIT's X11R5, rather than HP's version,
399: then you may need to add the following to config.h:
400:
401: #define srandom srand
402: #define random rand
403:
404: High Level Hardware Orion (m-orion.h; s-bsd4-2.h)
405:
406: This is the original microprogrammed hardware.
407: m- file ought to work.
408:
409: High Level Hardware Orion 1/05 (m-orion105.h; s-bsd4-2.h)
410:
411: Changes merged in 18.52. This is the one with the Clipper cpu.
412: Note that systems which lack NFS may need LOAD_AVE_TYPE changed to `double'.
413:
414: In 18.58, trouble was reported with X windows: XrmGetResource was
415: reported undefined in the library. You may need to change
416: XT_GetDefaults in x11term.c to make it link. If so, please
417: send a bug report saying exactly what change was needed.
418:
419: IBM PS2 (m-ibmps2-aix.h; s-usg5-2-2.h or s-usg5-3.h)
420:
421: Changes mostly merged in 18.55. You may need to put an #ifndef AIX
422: conditional around the definition of closedir in sysdep.c, and
423: perhaps delete the #include of sioctl.h. You may need to copy
424: /usr/lib/samples/hft/hftctl.c to the Emacs src directory.
425:
426: Use s-usg5-3.h on AIX 1.2.
427: s-usg5-2-2.h should work on either AIX 1.1 or 1.2, but may not work with
428: certain new X window managers, and may be suboptimal.
429:
430: IBM RS/6000 (m-ibmrs6000.h; s-aix3-1.h or s-aix3-2.h)
431:
432: Changes merged in 18.56. Note that for installation on AIX you must
433: use `make install.aix' rather than just `make'. Use s-aix3-2.h
434: on AIX 3.2 also.
435:
436: IBM RT/PC (m-ibmrt.h or m-ibmrt-aix.h; s-bsd4-3.h or s-usg5-2-2.h)
437:
438: 18.52 works on both operating systems.
439: Use s-bsd-4-3.h for the 4.3-like system AOS, and s-usg5-2-2.h for AIX.
440:
441: On BSD, if you have trouble, try compiling with a different compiler.
442:
443: On AIX, the file /usr/lib/samples/hft/hftctl.c must be compiled into
444: hftctl.o, with this result left in the src directory (hftctl.c is
445: part of the standard AIX distribution).
446:
447: window.c must not be compiled with -O on AIX.
448:
449: Integrated Solutions `Optimum V' (m-isi-ov.h; s-bsd4-2.h or s-bsd4-3.h)
450:
451: 18.52 said to work on some sort of ISI machine.
452: Version 18.45 worked (running on a Optimum V (VME bus, 68020)
453: BSD 4.2 (3.05e) system). 18.42 is reported to work on
454: a Qbus 68010 system. Has not been tried on `WorkStation' `Cluster
455: Compute Node' `Cluster WorkStation' or `Server Node' (Love the
456: StudLYCaps)
457:
458: Compilation with -O is rumored to break something.
459:
460: On recent system versions, you may need to undefine the macro UMAX
461: in etc/loadst.c and src/getpagesize.h. They stupidly defined this
462: in a system header file, which confuses Emacs (which thinks that UMAX
463: indicates the Umax operating system).
464:
465: Integrated Solutions 386 (m-is386.h; ??)
466:
467: Configuration file present in 18.57.
468:
469: Intel 80386 (m-intel386.h; s-bsd4-2.h, s-usg5-2-2.h, s-usg5-3.h, s-esix.h,
470: s-386ix.h, s-isc2-2.h, s-isc3-0.h, s-sco3-2-2.h, s-sco3-2-4.h,
471: or s-xenix.h)
472:
473: 18.59 should support a wide variety of operating systems.
474: Use s-isc2-2.h for Interactive 386/ix version 2.2
475: and s-isc3-0.h for versions 3.0 and 3.2.
476: Use s-386ix.h for prior versions.
477: Use s-esix.h for Esix.
478:
479: Use s-sco3-2-4.h for version 3.2.4, and s-sco3-2-2.h for version 3.2.2
480: (but it only makes a difference if you compile Emacs for X windows).
481: You may have to compile the cpp that comes with Emacs
482: and use that to preprocess src/ymakefile to get src/xmakefile.
483: s-sco3-2-1.h may work on SCO 3.2.1, but see the instructions in
484: that file for other changes you need to make.
485:
486: If you are using Xenix, see notes above under Xenix.
487:
488: Some sysV.3 systems seem to have bugs in `opendir';
489: for them, alter `config.h' to define NONSYSTEM_DIR_LIBRARY
490: and undefine SYSV_SYSTEM_DIR.
491:
492: If you use optimization on V.3, you may need the option -W2,'-y 0'
493: to prevent certain faulty optimization. Otherwise, fns.c won't work.
494:
495: On 386/ix, to link with shared libraries, add #define USG_SHARED_LIBRARIES
496: to config.h.
497:
498: On one V.4 system, it was necessary to define LIBS_TERMCAP as -ltermcap.
499:
500: Versions 3 and earlier of V.4 supposedly have problems
501: in the X11 libraries that prevent Emacs from working with X.
502: Version 4 of V.4 is said to have fixed this problem. See the
503: entry for System V Release 4, above. Similar problems occur on
504: SCO systems and perhaps also on ISC systems. There is no known
505: remedy except to get a different system.
506:
507: There is no consistency in the handling of certain system header files
508: on V.3.
509:
510: Some versions have sys/sioctl.h, and require it in sysdep.c.
511: But some versions do not have sys/sioctl.h.
512: For a given version of the system, this may depend on whether you have
513: X Windows or TCP/IP. Define or undefine NO_SIOCTL_H in config.h
514: according to whether you have the file.
515:
516: Likewise, some versions have been known to need sys/ttold.h, sys/stream.h,
517: and sys/ptem.h included in sysdep.c. If your system has these files,
518: try defining NEED_PTEM_H in config.h if you have trouble without it.
519:
520: You may find that adding -I/usr/X/include or -I/usr/netinclude or both
521: to CFLAGS avoids compilation errors on certain systems.
522:
523: Some versions convince sysdep.c to try to use `struct tchars'
524: but define `struct tc' instead; add `#define tchars tc'
525: to config.h to solve this problem.
526: Some systems have problems that can be solved by inserting
527: #undef TIOCGETC
528: in sysdep.c, near the place where this is done for XENIX.
529:
530: Intel 860 (m-intel860.h; s-usg5-4.h)
531:
532: Supposed to work in 18.58. See the notes for System V Release 4,
533: above, for notes on using X windows and using sockets.
534:
535: Iris 4D (m-iris4d.h; s-irix3-3.h or s-irix4-0.h)
536:
537: 18.58 is known to work on Silicon Graphics 4D series machines
538: with IRIX 3.3 or IRIX 4.0.
539:
540: Most irix3.3 systems do not have an ANSI C compiler, but a few do.
541: If you are using the ANSI C compiler, you may need to add
542: #define C_SWITCH_MACHINE -cckr
543: to config.h.
544:
545: There is a bug in IRIX that can sometimes leave ptys owned by
546: root with a permission of 622. This causes malfunctions in use
547: of subprocesses of Emacs. This may be fixed in IRIX 4.0.5.
548:
549: Iris 2500 Turbo (m-irist.h; s-iris3-5.h or s-iris3-6.h)
550:
551: 18.49 works. Use s-iris3-6.h for system versions 3.6 and up.
552: s-iris3-5.h is said to work with system version 2.5.
553: Note that the 3030 is the same machine as this.
554:
555: Macintosh
556:
557: We are boycotting Apple because of Apple's efforts to take away
558: our freedom to write compatible imitations of existing software.
559: If you value your freedom to write such programs, we urge you
560: not to buy from Apple, not to develop software for Apple, and
561: certainly not to accept a job with Apple.
562:
563: See the file APPLE in this directory for more information.
564:
565: Masscomp (m-masscomp.h; s-rtu.h)
566:
567: 18.36 worked on a 5500DP running RTU v3.1a and compiler version 3.2
568: with minor fixes that are included in 18.37. However, bizarre behavior
569: was reported for 18.36 on a Masscomp (model and version unknown but probably
570: a 68020 system). The report sounds like a compiler bug.
571:
572: A compiler bug affecting statements like
573: unsigned char k; unsigned char *p;... x = p[k];
574: has been reported for "C version 1.2 under RTU 3.1". We do not wish
575: to take the time to install the numerous workarounds required to
576: compensate for this bug; go complain to Masscomp.
577:
578: For RTU version 3.1, define FIRST_PTY_LETTER to be 'p' in s-rtu.h
579: (or #undef and redefine it in config.h) so that ptys will be used.
580:
581: GNU Emacs is said to have no chance of compiling on RTU versions
582: prior to v3.0.
583:
584: Megatest (m-mega68.h; s-bsd4-2.h)
585:
586: Emacs 15 worked; do not have any reports about Emacs 16 or 17
587: but any new bugs are probably not difficult.
588:
589: Mips (m-mips.h or m-mips4.h; s-usg5-2-2.h, s-bsd4-3.h)
590:
591: Changes merged in 18.39. Some fixes in 18.56.
592:
593: Use m-mips4.h for RISCOS version 4; use s-bsd4-3.h with the BSD world.
594:
595: If you are compiling with GCC, then you must run fixincludes;
596: the alternative of using -traditional won't work because
597: the definition of SIGN_EXTEND_CHAR uses the keyword `signed'.
598:
599: If the SYSV world is the default, then you probably need the following
600: line in etc/Makefile:
601:
602: CFLAGS= -g -systype bsd43
603:
604: Some operating systems on MIPS machines give SIGTRAP for division by
605: zero instead of the usual signals. The only real solution is to fix
606: the system to give a proper signal.
607:
608: In the meantime, you can change init_data in data.c if you wish.
609: Change it to handle SIGTRAP as well as SIGFPE. But this will have a
610: great disadvantage: you will not be able to run Emacs under a
611: debugger. I think crashing on division by zero is a lesser problem.
612:
613: Note that the proper m- file for the Decstation is m-pmax.h.
614:
615: Motorola Delta 147 (m-delta.h; s-usg5-3.h)
616:
617: m- file added in version 18.56.
618:
619: Motorola Delta 187 (m-delta88k.h; s-usg5-3.h)
620:
621: m- file added in version 18.58.
622: HAVE_X_MENU may work if you modify oldXMenu/Makefile to compile insque.c.
623:
624: National Semiconductor 32000 (m-ns32000.h; s-usg5-2.h)
625:
626: This is for a complete machine from National Semiconductor,
627: running Genix. Changes merged in version 19.
628:
629: NCR Tower 32 running System V release 2 (m-tower32.h; s-usg5-2-2.h)
630:
631: Works as of 17.56. If you change src/ymakefile so that CFLAGS includes
632: C_OPTIMIZE_SWITCH rather than C_DEBUG_SWITCH, check out the comments
633: in src/m-tower32.h about this.
634:
635: There is a report that compilation with -O did not work with 18.54.
636:
637: NCR Tower 32 running System V release 3 (m-tower32v3.h; s-usg5-3.h)
638:
639: Works as of 18.56. If you change src/ymakefile so that CFLAGS includes
640: C_OPTIMIZE_SWITCH rather than C_DEBUG_SWITCH, and do not use gcc, check
641: out the comments in src/m-tower32v3.h about this.
642:
643: NeXT (m-next.h; s-mach2.h)
644:
645: Changes merged in 18.59.
646:
647: Nixdorf Targon 31 (m-targon31.h; s-usg5-2-2.h)
648:
649: Changes merged in 18.56 may work.
650: It may be necessary to define C_ALLOCA in m-targon31.h
651: and it may be necessary to remove alloca from libc.a.
652: (The alloca in libc.a is said to be broken.)
653: Please report to the Foundation what works.
654:
655: Note that the "Targon 35" is really a Pyramid.
656:
657: Nu (TI or LMI) (m-nu.h; s-usg5-2.h)
658:
659: Version 18 is believed to work.
660:
661: pfa50 (m-pfa50.h; s-usg5-3.h)
662:
663: Changes mostly merged in 18.59.
664:
665: Plexus (m-plexus.h; s-usg5-2.h)
666:
667: Works as of 17.56.
668:
669: Pmax, Mips from DEC (m-pmax.h; s-bsd4-2.h)
670:
671: See under DECstation, above.
672:
673: Prime EXL (m-intel386.h; s-usg5-3.h)
674:
675: 18.54 should work.
676:
677: Pyramid (m-pyramid.h; s-bsd4-2.h)
678:
679: 18.58 seems to work on the MIServer 2/1T under OSx 5.1-910507.
680: You need to build Emacs in the Berkeley universe with
681: the `ucb' command, as in `ucb make' or `ucb build-install'.
682:
683: In OSx 4.0, it seems necessary to add the following two lines
684: to m-pyramid.h:
685: #define _longjmp longjmp
686: #define _setjmp setjmp
687:
688: In Pyramid system 2.5 there has been a compiler bug making
689: Emacs crash just after screen-splitting with Qnil containing 0.
690: A compiler that fixes this is Pyramid customer number 8494,
691: internal number 1923.
692:
693: Some versions of the pyramid compiler get fatal
694: errors when the -gx compiler switch is used; if this
695: happens to you, change src/m-pyramid.h to define
696: C_DEBUG_SWITCH with an empty definition.
697:
698: Some old system versions may require you to define PYRAMID_OLD
699: in when alloca.s is preprocessed, in order to define _longjmp and _setjmp.
700:
701: Pyramid MIPS systems (m-pyrmips.h; s-usg5-4.h)
702:
703: Changes merged in 18.59; may work. Dumping is not supported.
704: Use CPP=/usr/ccs/lib/cpp when running make in src.
705:
706: Sequent Balance (m-sequent.h; s-bsd4-2.h)
707:
708: Emacs 18.51 should work on system version
709: 3.0. 18.5[23] is said to work. Delete some lines at the end of
710: m-sequent.h for earlier system versions.
711:
712: Sequent Symmetry (m-seq386.h; s-bsd4-2.h)
713:
714: Changes merged in 18.59 for compiling with GCC.
715:
716: SONY News (m-news.h; s-bsd4-2.h, or s-bsd4-3.h for system release 3)
717:
718: 18.52 should work.
719:
720: SONY News 3000 series (RISC NEWS) (m-news-risc.h; s-bsd4-3.h)
721:
722: Works, as of 18.56. Note that this is a MIPS architecture machine.
723:
724: Some versions of the operating system give SIGTRAP for division by zero
725: instead of the usual signals. This causes division by zero
726: to make Emacs crash. The system should be fixed to give the proper signal.
727: Changing Emacs is not a proper solution, because it would prevent
728: Emacs from working under any debugger. But you can change init_data
729: in data.c if you wish.
730:
731: Stride (m-stride.h; s-usg5-2.h)
732:
733: Works (most recent news for 18.30) on their release 2.0.
734: For release 2.2, see the end of m-stride.h.
735: It may be possible to run on their V.1 system but changes
736: in the s- file would be needed.
737:
738: Sun 1, 2 and 3 (m-sun1.h, m-sun2.h, m-sun3.h;
739: s-bsd4-2.h, s-sunos4-0.h or s-sunos4-1.h)
740:
741: There are three m- files for different versions of SunOS.
742: All are derived from Berkeley 4.2. Emacs 17 has run on all of them.
743: Whether you should use m-sun1.h, m-sun2.h or m-sun3.h depends
744: on the VERSION OF THE OPERATING SYSTEM you have.
745: You will need to use m-sun3.h on Sun 2's running SunOS release 3.
746:
747: For SunOS release 4 on a Sun 2 or Sun 3, use m-sun3.h and s-sunos4-1.h.
748: (Use s-sunos4-0.h instead if using system version 4.0.*.)
749: See the file etc/SUNBUG for how to solve problems caused by bugs in
750: the "export" version of SunOS 4.
751:
752: If you get inappropriate "unknown host" errors from
753: open-network-stream, get the distribution of `bind' (the BSD
754: name-server), build libresolv.a, and link Emacs with -lresolv. This
755: problem is due to obsolete software in the nonshared standard
756: library.
757:
758: If you want to use SunWindows, define HAVE_SUN_WINDOWS
759: in config.h to enable a special interface called `emacstool'.
760: The definition must *precede* the #include "m-sun3.h".
761: System version 3.2 is required for this facility to work.
762:
763: We recommend that you instead use the X window system, which
764: has technical advantages, is an industry standard, and is also
765: free software.
766:
767: If you are compiling for X windows, and the X window library was
768: compiled to use the 68881, then you must edit config.h according
769: the comments at the end of m-sun3.h.
770:
771: It is advisable to add #define ForceNormalLib YES before building
772: X11R5, to force creation of a nonshared library (as well as the
773: shared X library). Emacs does not use shared libraries, so it
774: needs to have a nonshared X library in order to run with X.
775:
776: Note that Emacs on a Sun is not really as big as it looks.
777: As dumped, it includes around 200k of zeros between the
778: original text section and the original data section
779: (now remapped as part of the text). These are never
780: swapped in.
781:
782: To build a single Emacs that will run on Sun 2 and Sun 3
783: HARDWARE, just build it on the Sun 2.
784:
785: Sun 4 (m-sparc.h; s-bsd4-2.h or s-sunos4-0.h or s-sunos4-1.h or s-sol2.h)
786:
787: Works under Sunos 4; changes for Solaris 2 merged in Emacs 18.59.
788: You may need to use CPP=/usr/ucb/cc -E in src/Makefile on Solaris 2.
789:
790: Some people have said optimizing compilation
791: does not work; some say that -O2 (whatever that is) works
792: perhaps with a small change.
793:
794: See the entry above for the Sun 3; most of the information
795: applies to the Sun 4 as well.
796:
797: Sun Roadrunner (m-sun386.h; s-sunos4-0.h)
798:
799: Changes merged in 18.51.
800:
801: Tadpole (m-tad68.h; s-usg5-3.h)
802:
803: Changes merged in 18.58; minor fixes in 18.59.
804:
805: You may need to edit Makefile to change the variables LIBDIR and
806: BINDIR from /usr/local to /usr/contrib.
807:
808: To give movemail access to /usr/mail, you may need to execute
809:
810: chmod 2755 etc/movemail; chgrp mail etc/movemail
811:
812: Tahoe (m-tahoe.h; s-bsd4-2.h or s-bsd4-3.h)
813:
814: 18.52 known to work on some Tahoes, but a compiler bug intervenes
815: on others. Some Emacs versions have worked in Unisys 1r4
816: (not in 1r3) and CCI I.21.
817:
818: If you have trouble compiling etc/loadst.c, turn off the definition
819: of DKSTAT_HEADER_FILE in m-tahoe.h.
820:
821: Tandem Integrity S2 (m-tandem-s2.h; s-usg5-3.h)
822:
823: Changes merged in 18.56 but subprocess support is turned off.
824: You will probably want to see if you can make subprocesses work.
825:
826: You must edit etc/Makefile to define LOADLIBES = -mld.
827:
828: Tektronix 16000 box (6130?) (m-ns16000.h; s-bsd4-2.h)
829:
830: Emacs 17.61 worked.
831:
832: Tektronix 4300 (m-tek4300.h; s-bsd4-3.h)
833:
834: Emacs 18.58 should work.
835:
836: Depending on which linker you use, you might want to change
837: the value of TEXT_START in m-tek4300.h; though the native linker
838: does use zero, it is possible (and reasonable) to use a linker
839: that starts text elsewhere, like 0x2000.
840:
841: Triton 88 (m-triton88.h; s-usg5-3.h?)
842:
843: Changes merged in 18.58.
844:
845: Ustation E30 (SS5E) (m-ustation.h; s-unipl5-2.h)
846:
847: Changes merged in 18.52; don't know whether they work.
848:
849: Vax running Berkeley Unix (m-vax.h; s-bsd4-1.h, s-bsd4-2.h or s-bsd4-3.h)
850:
851: Works.
852:
853: Vax running Ultrix (m-vax.h; s-bsd4-2.h)
854:
855: Works. See under Ultrix for problems using X windows on Ultrix.
856:
857: Vax running System V rel 2 (m-vax.h; s-usg5-2.h)
858:
859: 18.27 Works.
860:
861: Vax running System V rel 0 (m-vax.h; s-usg5-0.h)
862:
863: Works as of 18.36.
864:
865: Vax running VMS (m-vax.h; s-vms.h but on VMS they are m_vax.h and s_vms.h)
866:
867: 18.36 believed to work. Addition of features is necessary to make
868: this Emacs version more usable.
869:
870: Whitechapel MG1 (m-mg1.h, s-?)
871:
872: May work. Supposedly no changes were needed except the m- file.
873: I do not know what Unix version runs on them.
874:
875: Wicat (m-wicat.h; s-usg5-2.h)
876:
877: Changes merged as of 18.6; whether they work is unknown.
878: See comments in m-wicat.h for things you should change
879: depending on the system and compiler version you have.
