2e493ffe | 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 | |
5 | system/machine. | |
77d78be1 | 6 | |
cbd6b57c JB |
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 | |
14 | description files. | |
2e493ffe | 15 | |
da33ff57 JB |
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. | |

cbd6b57c | 28 | Alliant (fx80-alliant-bsd): |
2e493ffe | 29 | |
52f8dbf8 | 30 | 18.52 worked on system version 4. Previous Emacs versions were |
2e493ffe JB |
31 | known to work on previous system versions. |
32 | ||
cbd6b57c JB |
33 | If you are using older versions of their operating system, you may |
34 | need to edit `src/config.h' to use `m/alliant1.h' (on version 1) or | |
35 | `m/alliant.h' (on versions 2 and 3). | |
77d78be1 | 36 | |
cbd6b57c | 37 | Alliant FX/2800 (i860-alliant-bsd) |
77d78be1 JB |
38 | |
39 | Known to work with 18.58 and OS version 2.2, compiler version 1.3. | |
2e493ffe | 40 | |
cbd6b57c | 41 | Altos 3068 (m68k-altos-sysv) |
2e493ffe | 42 | |
52f8dbf8 | 43 | 18.52 was said to work, provided you don't compile unexec.c with -O. |
2e493ffe | 44 | |
cbd6b57c | 45 | Amdahl UTS (580-amdahl-sysv) |
2e493ffe JB |
46 | |
47 | Small changes for 18.38 were merged in 18.39. It is mostly | |
48 | working, but at last report a bug sometimes causes Emacs to | |
49 | grab very large amounts of memory. No fix or explanation | |
50 | has yet been reported. It may be possible to find this bug | |
51 | if you find which Emacs command it happens within and then | |
52 | run that command with a breakpoint set at malloc. | |
53 | ||
54 | The 5.2u370 compiler is so brain damaged that it is not | |
55 | even worth trying to use it. Success was obtained with the | |
56 | uts native C compiler on uts version 5.2.5. | |
57 | ||
cbd6b57c | 58 | Apollo running Domain (m68k-apollo-bsd) |
2e493ffe JB |
59 | |
60 | 18.52 works, to some extent. | |
52f8dbf8 | 61 | Code for dumping Emacs has been written, but we cannot distribute it yet. |
2e493ffe JB |
62 | There are reports of bugs in cc -O on this system. |
63 | ||
cbd6b57c | 64 | In `lib-src/Makefile', don't expect emacsclient and emacsserver to |
2e493ffe JB |
65 | compile. You might want to remove them from your makefile. |
66 | ||
67 | Supposedly something in dired.c runs into a compiler bug. | |
77d78be1 JB |
68 | Paraphrasing the statement should avoid the problem. I have not yet |
69 | received word as to the exact statement this is. | |
2e493ffe | 70 | |
52f8dbf8 ER |
71 | The Apollo has a bizarre operating system which does not permit |
72 | Emacs to be dumped with preloaded pure Lisp code. Therefore, each | |
73 | time you start Emacs on this system, the standard Lisp code is loaded | |
74 | into it. Expect it to take a long time. You can prevent loading of | |
75 | the standard Lisp code by specifying the -nl switch. It must | |
76 | come at the beginning of the command line; only the -t and -batch | |
77 | switches may come before it. | |
78 | ||
79 | There is one remaining problem on the Apollo. You must replace | |
80 | the CPP line in src/Makefile with "CPP = /usr/lib/cpp". | |
81 | The C preprocessor lives there rather than in /lib/cpp because the | |
82 | Aegis OS uses the /lib directory as the repository for shared libraries. | |
83 | ||
84 | ||
85 | Here is a design for a method of dumping and reloading the relevant | |
86 | necessary impure areas of Emacs. | |
87 | ||
88 | On dumping, you need to dump only the array `pure' plus the | |
89 | locations that contain values of forwarded Lisp variables or that are | |
90 | protected for garbage collection. The former can be found by a | |
91 | garbage- collection-like technique, and the latter are in the | |
92 | staticprolist vector (see alloc.c for both things). | |
93 | ||
94 | Reloading would work in an Emacs that has just been started; except | |
95 | when a switch is specified to inhibit this, it would read the dump | |
96 | file and set all the appropriate locations. The data loaded must be | |
97 | relocated, but that's not hard. Those locations that are of type | |
98 | Lisp_Object can be found by a technique like garbage-collection, and | |
99 | those of them that point to storage can be relocated. The other data | |
100 | read from the file will not need to be relocated. | |
101 | ||
102 | The switch to inhibit loading the data base would be used when it | |
103 | is time to dump a new data base. | |
104 | ||
105 | This would take a few seconds, which is much faster than loading | |
106 | the Lisp code of Emacs from scratch. | |

cbd6b57c | 108 | AT&T 3b2, 3b5, 3b15, 3b20 (we32k-att-sysv) |
2e493ffe JB |
109 | |
110 | Emacs will probably not work with certain kernel constants too small. | |
111 | ||
112 | In param.h CDLIMIT should be at least (1L << 12) in order to allow | |
52f8dbf8 | 113 | processes to write up to 2 Mbyte files. This parameter is configurable |
2e493ffe JB |
114 | by normal means in /etc/master.d/kernel; examine that file for the |
115 | symbol CDLIMIT or ULIMIT, and raise it by several powers of 2. Then | |
116 | do normal kernel rebuild things via "cd /boot; mkboot -k KERNEL" and so | |
52f8dbf8 | 117 | forth. |
2e493ffe JB |
118 | |
119 | In seg.h NSEGP and STACKSEG should be at least 16 and 4 respectively | |
120 | to allow processes with total size of up to 2Mbytes. | |
121 | However, I'm told it is unlikely this would fail to be true. | |
122 | ||
123 | The MAXMEM may also prevent Emacs from running. The file | |
124 | 3B-MAXMEM in this directory explains how to increase MAXMEM. | |
125 | ||
cbd6b57c | 126 | AT&T 7300 or 3b1 (m68k-att-sysv) |
2e493ffe | 127 | |
52f8dbf8 | 128 | 18.52 worked. If you have strange troubles with dumping |
cbd6b57c | 129 | Emacs, delete the last few lines from `src/m/7300.h' and recompile. |
77d78be1 | 130 | These lines are supposed to produce a sharable executable. |
2e493ffe | 131 | |
cbd6b57c | 132 | `src/m/7300.h' defines SHORTNAMES because operating system versions |
2e493ffe | 133 | older than 3.5 did not support long symbol names. Version 3.5 does |
77d78be1 JB |
134 | support them, so you can remove the #define SHORTNAMES in that |
135 | version. | |

145 | Celerity (celerity-celerity-bsd4.2) |
146 | ||
52f8dbf8 | 147 | Version 18.49 worked. This configuration name is a hack, because we |
cbd6b57c JB |
148 | don't know the processor used by Celerities. If someone |
149 | who uses a Celerity could get in touch with us, we can teach | |
150 | config.sub a better name for the configuration. | |
2e493ffe | 151 | |
cbd6b57c | 152 | Clipper (clipper-???) |
2e493ffe | 153 | |
cbd6b57c JB |
154 | Version 19 has support for some brand of clipper system. If you |
155 | have successfully built Emacs 19 on some sort of clipper system, let | |
156 | us know so we can flesh out this entry. | |
2e493ffe | 157 | |
2e493ffe JB |
158 | Note that the Orion 105 is also a clipper, but some system-related |
159 | parameters are different. | |

162 | c38-convex-bsd) | |
2e493ffe | 163 | |
52f8dbf8 | 164 | 18.53 supposedly to work. |
2e493ffe | 165 | |
cbd6b57c | 166 | Cubix QBx/386 (i386-cubix-sysv) |
2e493ffe JB |
167 | |
168 | Changes merged in 19.1. Systems before 2/A/0 may fail to compile etags.c | |
169 | due to a compiler bug. | |
170 | ||
cbd6b57c | 171 | Cydra 5 (cydra-cydrome-sysv) |
2e493ffe JB |
172 | |
173 | 18.51 worked in one version of their operating system but stopped | |
174 | working in a newer version. This has not been fixed. | |
175 | ||
cbd6b57c | 176 | DECstation (mips-dec-ultrix or mips-dec-osf) |
b7cceaf1 | 177 | |
cbd6b57c | 178 | Version 19 works under Ultrix. |
b7cceaf1 JB |
179 | |
180 | See under Ultrix for problems using X windows on Ultrix. | |
181 | Note that this is a MIPS machine. | |
2e493ffe | 182 | |
64d8c7fb | 183 | For Ultrix versions 4.1 or earlier, you may need to define |
cbd6b57c | 184 | SYSTEM_MALLOC in `src/m/pmax.h', because XvmsAlloc.o in libX11.a seems |
64d8c7fb JB |
185 | to insist on defining malloc itself. |
186 | ||
77d78be1 | 187 | For Ultrix versions prior to 4.0, you may need to delete |
cbd6b57c | 188 | the definition of START_FILES from `src/m/pmax.h'. |

cbd6b57c | 190 | Motorola Delta 147 (m68k-motorola-sysv) |
2e493ffe JB |
191 | |
192 | Motorola Delta boxes running System V/68 release 3. | |
193 | (tested on sys1147 with SVR3V5). Changes merged in 19.1. | |
194 | ||
cbd6b57c | 195 | Motorola Delta 187 (m88k-motorola-sysv or m88k-motorola-m88kbcs) |
77d78be1 JB |
196 | |
197 | Machine support added in version 19. | |
198 | HAVE_X_MENU does not work due to lack of insque. | |
199 | ||
cbd6b57c | 200 | Dual running System V (m68k-dual-sysv) |
2e493ffe | 201 | |
52f8dbf8 | 202 | As of 17.46, this worked except for a few changes |
2e493ffe JB |
203 | needed in unexec.c. |
204 | ||
cbd6b57c | 205 | Dual running Uniplus (m68k-dual-uniplus) |
2e493ffe | 206 | |
52f8dbf8 | 207 | Worked, as of 17.51. |
2e493ffe | 208 | |
cbd6b57c | 209 | Elxsi 6400 (elxsi-elxsi-sysv) |
2e493ffe JB |
210 | |
211 | Changes for 12.0 release are in 19.1. | |
212 | Dumping should work now. | |
213 | ||
cbd6b57c | 214 | Encore machine (ns16k-encore-bsd) |
2e493ffe JB |
215 | |
216 | This machine bizarrely uses 4.2BSD modified to use the COFF format | |
217 | for object files. Works (as of 18.40). For the APC processor you | |
cbd6b57c | 218 | must enable two lines at the end of `src/s/umax.h', which are commented |
2e493ffe JB |
219 | out in the file as distributed. |
220 | ||
221 | WARNING: If you compile Emacs with the "-O" compiler switch, you | |
222 | must also use the "-q enter_exits" switch so that all functions have | |
223 | stack frames. Otherwise routines that call `alloca' all lose. | |
224 | ||
225 | A kernel bug in some system versions causes input characters to be lost | |
226 | occasionally. | |
227 | ||
cbd6b57c | 228 | GEC 63 (local-gec63-usg5.2) |
2e493ffe | 229 | |
cbd6b57c JB |
230 | Changes are partially merged in version 18, but certainly require |
231 | more work. Let us know if you get this working, and we'll give it a | |
232 | real configuration name. | |
2e493ffe | 233 | |
cbd6b57c | 234 | Gould Power Node (pn-gould-bsd4.2 or pn-gould-bsd4.3) |
2e493ffe JB |
235 | |
236 | 18.36 worked on versions 1.2 and 2.0 of the operating system. | |
237 | ||
cbd6b57c | 238 | On UTX/32 2.0, use pn-gould-bsd4.3. |
2e493ffe | 239 | |
cbd6b57c JB |
240 | On UTX/32 1.2 and UTX/32S 1.0, use pn-gould-bsd4.2 and note that |
241 | compiling `lib-src/sorted-doc' tickles a compiler bug: remove the -g | |
77d78be1 | 242 | flag to cc in the makefile. |
2e493ffe JB |
243 | |
244 | UTX/32 1.3 has a bug in the bcopy library routine. Fix it by | |
cbd6b57c | 245 | #undef BSTRING in `src/m/gould.h'. |
2e493ffe JB |
246 | |
247 | Version 19 incorporates support for releases 2.1 and later of UTX/32. | |
248 | A site running a pre-release of 2.1 should #define RELEASE2_1 in config.h. | |
249 | ||
cbd6b57c | 250 | Gould NP1 (np1-gould-bsd) |
2e493ffe JB |
251 | |
252 | Version 19 supposedly works. | |
253 | ||
cbd6b57c | 254 | Honeywell XPS100 (xps100-honeywell-sysv) |
2e493ffe JB |
255 | |
256 | Config file added in version 19. | |
257 | ||
cbd6b57c | 258 | HP 9000 series 200 or 300 (m68k-hp-bsd or m68k-hp-hpux7.) |
2e493ffe | 259 | |
03b600f7 JB |
260 | Version 19 works under BSD. |
261 | ||
2e493ffe JB |
262 | These machines are 68000-series CPUs running HP-UX |
263 | (a derivative of sysV with some BSD features) or BSD 4.3 ported by Utah. | |
cbd6b57c | 264 | The operating system suffix determines which system Emacs is built for. |
2e493ffe JB |
265 | |
266 | Series 200 HPUX runs Emacs only if it has the "HP-UX upgrade". | |
267 | ||
956ace37 JB |
268 | If you are running HP-UX release 8.0 or later, you need the optional |
269 | "C/ANSI C" software in order to build Emacs (older releases of HP-UX | |
270 | do not require any special software). If the file "/etc/filesets/C" | |
271 | exists on your machine, you have this software, otherwise you do not. | |
272 | ||
2e493ffe JB |
273 | Note that HP has used two incompatible assembler syntaxes, |
274 | and has recently changed the format of C function frames. | |
cbd6b57c | 275 | `src/crt0.c' and `src/alloca.s' have been conditionalised for the new |
2e493ffe JB |
276 | assembler and new function-entry sequence. You may need to define |
277 | OLD_HP_ASSEMBLER if you are using an older hpux version. If you | |
278 | have an official (bought from HP) series 300 machine you have | |
279 | the new assembler. Kernels that are 5.+ or later have new | |
280 | assembler. A Series 200 that has been upgraded to a 68010 | |
281 | processor and a 5.+ kernel has the new compiler. | |
282 | ||
283 | Define C_SWITCH_MACHINE to be +X to make a version of Emacs that | |
284 | runs on both 68010 and 68020 based hp-ux's. | |
285 | ||
286 | Define HPUX_68010 if you are using the new assembler, for | |
287 | a system that has a 68010 without a 68881. This is to say, | |
288 | a s200 (upgraded) or s310. | |
289 | ||
290 | Define the symbol HPUX_NET if you have the optional network features | |
291 | that include the `netunam' system call. This is refered to as | |
292 | Network Services (NS/9000) in HP literature. | |
293 | ||
2e493ffe JB |
294 | HP 9000 series 500: not supported. |
295 | ||
296 | The series 500 has a seriously incompatible memory architecture | |
297 | which relocates data in memory during execution of a program, | |
298 | and support for it would be difficult to implement. | |
299 | ||
cbd6b57c | 300 | HP 9000 series 800 (Spectrum) (hppa1.0-hp-hpux) |
2e493ffe JB |
301 | |
302 | These files support HP's Precision Architecture machines | |
303 | running HP-UX. It has been moderately tested on the Series | |
304 | 840. | |
305 | ||
956ace37 JB |
306 | If you are running HP-UX release 8.0 or later, you need the optional |
307 | "C/ANSI C" software in order to build Emacs (older releases of HP-UX | |
308 | do not require any special software). If the file "/etc/filesets/C" | |
309 | exists on your machine, you have this software, otherwise you do not. | |
310 | ||
cbd6b57c | 311 | High Level Hardware Orion (orion-highlevel-bsd) |
2e493ffe JB |
312 | |
313 | This is the original microprogrammed hardware. | |
77d78be1 | 314 | Machine description file ought to work. |
2e493ffe | 315 | |
cbd6b57c | 316 | High Level Hardware Orion 1/05 (clipper-highlevel-bsd) |
2e493ffe JB |
317 | |
318 | Changes merged in 18.52. This is the one with the Clipper cpu. | |
319 | Note that systems which lack NFS need LOAD_AVE_TYPE changed to `double'. | |
320 | ||
321 | C compiler has a bug; it loops compiling eval.c. | |
322 | Compile it by hand without optimization. | |
323 | ||
cbd6b57c | 324 | IBM PS/2 (i386-ibm-aix1.1 or i386-ibm-aix1.2) |
2e493ffe JB |
325 | |
326 | Changes merged in version 19. You may need to copy | |
327 | /usr/lib/samples/hft/hftctl.c to the Emacs src directory. | |
328 | ||
cbd6b57c JB |
329 | i386-ibm-aix1.1 may not work with certain new X window managers, and |
330 | may be suboptimal. | |
77d78be1 | 331 | |
cbd6b57c | 332 | IBM RS/6000 (rs6000-ibm-aix) |
2e493ffe | 333 | |
a328c9ef JB |
334 | Changes merged in version 19. Currently the configuration |
335 | does not actually depend on the version of AIX. | |
2e493ffe | 336 | |
ca21f8b1 JB |
337 | Compiling with -O using the IBM compiler has been known |
338 | to make Emacs work incorrectly. | |
2e493ffe | 339 | |
cbd6b57c | 340 | IBM RT/PC (romp-ibm-bsd or romp-ibm-aix) |
2e493ffe | 341 | |
52f8dbf8 | 342 | 18.52 worked on both operating systems. |
cbd6b57c | 343 | Use romp-ibm-bsd for the 4.2-like system and romp-ibm-aix for AIX. |
2e493ffe JB |
344 | |
345 | On BSD, if you have trouble, try compiling with a different compiler. | |
346 | ||
347 | On AIX, the file /usr/lib/samples/hft/hftctl.c must be compiled into | |
348 | hftctl.o, with this result left in the src directory (hftctl.c is | |
349 | part of the standard AIX distribution). | |
350 | ||
351 | window.c must not be compiled with -O on AIX. | |
352 | ||
cbd6b57c | 353 | Integrated Solutions `Optimum V' (m68k-isi-bsd4.2 or -bsd4.3) |
2e493ffe JB |
354 | |
355 | 18.52 said to work on some sort of ISI machine. | |
356 | Version 18.45 worked (running on a Optimum V (VME bus, 68020) | |
357 | BSD 4.2 (3.05e) system). 18.42 is reported to work on | |
358 | a Qbus 68010 system. Has not been tried on `WorkStation' `Cluster | |
359 | Compute Node' `Cluster WorkStation' or `Server Node' (Love the | |
360 | StudLYCaps) | |
361 | ||
362 | Compilation with -O is rumored to break something. | |
363 | ||
364 | On recent system versions, you may need to undefine the macro UMAX | |
cbd6b57c | 365 | in `lib-src/loadst.c' and `src/getpagesize.h'. They stupidly defined this |

379 | It isn't clear what to do on an SCO system. The system's C |
380 | preprocessor doesn't seem to handle the src subdirectory's Make | |
381 | trickery, so you will probably need to install the GNU C preprocessor. | |

385 | Some sysV.3 systems seem to have bugs in `opendir'; | |
386 | for them, alter `config.h' to define NONSYSTEM_DIR_LIBRARY | |
387 | and undefine SYSV_SYSTEM_DIR. | |
388 | ||
389 | If you use optimization on V.3, you may need the option -W2,'-y 0' | |
390 | to prevent certain faulty optimization. | |
391 | ||
0ec1ba5b JB |
392 | On 386/ix, to link with shared libraries, add #define USG_SHARED_LIBRARIES |
393 | to config.h. | |
394 | ||
2e493ffe JB |
395 | There is no consistency in the handling of certain system header files |
396 | on V.3. | |
397 | ||
398 | Some versions have sys/sioctl.h, and require it in sysdep.c. | |
399 | But some versions do not have sys/sioctl.h. | |
0ec1ba5b JB |
400 | For a given version of the system, this may depend on whether you have |
401 | X Windows or TCP/IP. Define or undefine NO_SIOCTL_H in config.h | |
402 | according to whether you have the file. | |
403 | ||
404 | Likewise, some versions have been known to need sys/ttold.h, sys/stream.h, | |
405 | and sys/ptem.h included in sysdep.c. If your system has these files, | |
406 | try defining NEED_PTEM_H in config.h if you have trouble without it. | |
407 | ||
408 | You may find that adding -I/usr/X/include or -I/usr/netinclude or both | |
409 | to CFLAGS avoids compilation errors on certain systems. | |
410 | ||
2e493ffe JB |
411 | Some versions convince sysdep.c to try to use `struct tchars' |
412 | but define `struct tc' instead; add `#define tchars tc' | |
413 | to config.h to solve this problem. | |

0f6c0bb2 JB |
427 | Most irix3.3 systems do not have an ANSI C compiler, but a few do. |
428 | If you are using the ANSI C compiler, you may need to add | |
429 | #define C_SWITCH_MACHINE -cckr | |
430 | to config.h. | |

0f6c0bb2 JB |
432 | There is a bug in IRIX that can sometimes leave ptys owned by |
433 | root with a permission of 622. This causes malfunctions in use | |

2e493ffe JB |
447 | |
448 | 18.36 worked on a 5500DP running RTU v3.1a and compiler version 3.2 | |
449 | with minor fixes that are included in 18.37. However, bizarre behavior | |
450 | was reported for 18.36 on a Masscomp (model and version unknown but probably | |
451 | a 68020 system). The report sounds like a compiler bug. | |
452 | ||
453 | A compiler bug affecting statements like | |
454 | unsigned char k; unsigned char *p;... x = p[k]; | |
455 | has been reported for "C version 1.2 under RTU 3.1". We do not wish | |
456 | to take the time to install the numerous workarounds required to | |
457 | compensate for this bug; go complain to Masscomp. | |

b7cceaf1 JB |
479 | |
480 | If you are compiling with GCC, then you must run fixincludes; | |
481 | the alternative of using -traditional won't work because | |
482 | the definition of SIGN_EXTEND_CHAR uses the keyword `signed'. | |
483 | ||
484 | If the SYSV world is the default, then you probably need the following | |
485 | line in etc/Makefile: | |
486 | ||
487 | CFLAGS= -g -systype bsd43 | |
488 | ||
489 | Some operating systems on MIPS machines give SIGTRAP for division by | |
490 | zero instead of the usual signals. The only real solution is to fix | |
491 | the system to give a proper signal. | |
492 | ||
493 | In the meantime, you can change init_data in data.c if you wish. | |
494 | Change it to handle SIGTRAP as well as SIGFPE. But this will have a | |
495 | great disadvantage: you will not be able to run Emacs under a | |
496 | debugger. I think crashing on division by zero is a lesser problem. | |

541 | You need to build Emacs in the Berkeley universe with |

543 | ||
2e493ffe | 544 | In OSx 4.0, it seems necessary to add the following two lines |

548 | ||
549 | In Pyramid system 2.5 there has been a compiler bug making | |

580 | Some versions of the operating system give SIGTRAP for division by zero |
581 | instead of the usual signals. This causes division by zero | |
582 | to make Emacs crash. The system should be fixed to give the proper signal. | |
583 | Changing Emacs is not a proper solution, because it would prevent | |
584 | Emacs from working under any debugger. But you can change init_data | |
585 | in data.c if you wish. | |

2e493ffe | 599 | |
cbd6b57c JB |
600 | It's important to include the SunOS version number in the |
601 | configuration name. For example, for SunOS release 4.0 on a Sun 3, | |
602 | use `m68k-sun-sunos4.0'; for SunOS release 4.1 on a Sparc, use | |
603 | `sparc-sun-sunos4.1'. | |
604 | ||
605 | Use `m68k' for the 68000-based Sun boxes, `sparc' for Sparcstations, | |
606 | and `i386' for Sun Roadrunners. | |
607 | ||
608 | There are three machine files for the different versions of SunOS | |
609 | that run on the Motorola 68000 processors. All are derived from | |
610 | Berkeley 4.2. Emacs 17 has run on all of them. | |

614 | |
615 | If you have trouble using open-network-stream, get the | |
616 | distribution of `bind' (the BSD name-server), build libresolv.a, | |
617 | and link Emacs with -lresolv. This problem is due to obsolete | |
618 | software in the nonshared standard library. | |
619 | ||
620 | If you want to use SunWindows, define HAVE_SUN_WINDOWS | |
621 | in config.h to enable a special interface called `emacstool'. | |
77d78be1 | 622 | The definition must *precede* the #include "machine.h". |
2e493ffe JB |
623 | System version 3.2 is required for this facility to work. |
624 | ||
625 | We recommend that you instead use the X window system, which | |
626 | has technical advantages, is an industry standard, and is also | |
627 | free software. | |
628 | ||
629 | If you are compiling for X windows, and the X window library was | |
630 | compiled to use the 68881, then you must edit config.h according | |
cbd6b57c | 631 | the comments at the end of `src/m/sun3.h'. |
2e493ffe JB |
632 | |
633 | Note that Emacs on a Sun is not really as big as it looks. | |
634 | As dumped, it includes around 200k of zeros between the | |
635 | original text section and the original data section | |
636 | (now remapped as part of the text). These are never | |
637 | swapped in. | |
638 | ||
639 | To build a single Emacs that will run on Sun 2 and Sun 3 | |
640 | HARDWARE, just build it on the Sun 2. | |

648 | There is a bug in the Export version of SunOS 4.0 shipped outsde the |
649 | US; it has something to do with Pentagon export restrictions on the | |
650 | DES chips in Suns. The symptom is that "cc -Bstatic ..." WILL NOT | |
651 | WORK ON SUNOS 4.0 EXPORT without a little help from "ar". The | |
652 | static C-library is /lib/libc.a, and this is where the problem | |
653 | occurs. There are a bunch of .o files in there relating to DES | |
654 | stuff (des_crypt.o, des_soft.o, _crypt.o, etc). All of them will | |
655 | cause cc -Bstatic to die with these errors: | |
656 | ||
657 | > _edata: ld: user attempt to redefine loader-defined symbol | |
658 | > _end: user attempt to redefine loader-defined symbol | |
659 | > _etext: /lib/libc.a(des_crypt.o): multiply defined | |
660 | ||
661 | In order to make cc -Bstatic useful, you must remove all the | |
662 | brain-damaged .o files from /lib/libc.a. To do this use | |
663 | ||
664 | ar d /lib/libc.a des_crypt.o des_soft.o _crypt.o .... | |
665 | ||
666 | (Make a backup of /lib/libc.a first, you may decide you need the "real" | |
667 | thing someday). Note that there are a bunch of these files, these may | |
668 | not be all of them. You will find them quick enough by trying to | |
669 | compile ANY C program, even one which does NOTHING. | |

2e493ffe | 726 | |
52f8dbf8 | 727 | 18.36 was believed to work on VMS. Addition of features is necessary |
cbd6b57c | 728 | to make this Emacs version more usable. |
2e493ffe | 729 | |
cbd6b57c | 730 | Whitechapel MG1 (ns16k-whitechapel-?) |
2e493ffe | 731 | |
cbd6b57c JB |
732 | May work. Supposedly no changes were needed except in `src/m/mg1.h' |
733 | file. I do not know what Unix version runs on them. | |
2e493ffe | 734 | |
cbd6b57c | 735 | Wicat (m68k-wicat-sysv) |
2e493ffe | 736 | |
cbd6b57c JB |
737 | Changes merged as of 18.6; whether they work is unknown. |
738 | See comments in `src/m/wicat.h' for things you should change | |
739 | depending on the system and compiler version you have. | |
740 | \f | |
741 | Here is a summary of the systems supported: | |
2e493ffe | 742 | |
cbd6b57c | 743 | Berkeley 4.1 (bsd4.1) |
2e493ffe | 744 | |
cbd6b57c | 745 | Works on vaxes. |
2e493ffe | 746 | |
cbd6b57c | 747 | Berkeley 4.2 (bsd4.2) |
2e493ffe | 748 | |
cbd6b57c JB |
749 | Works on several machines. |
750 | ||
751 | Berkeley 4.3 (bsd4.3) | |
752 | ||
753 | Works, on Vaxes at least. | |
754 | ||
755 | Microport | |
756 | ||
757 | See under "Intel 386". | |
758 | ||
759 | System V rel 0 (usg5.0) | |
760 | ||
761 | Works, on Vaxes and 3bxxx's. | |
762 | There are some problems in 18.37 due to shortnames/cccp problems: | |
763 | use the emacs 17 cpp if you have it. | |
764 | ||
765 | System V rel 2 (usg5.2) | |
766 | ||
767 | Works on various machines. | |
768 | On some (maybe all) machines the library -lPW exists and contains | |
769 | a version of `alloca'. On these machines, to use it, put | |
770 | #define HAVE_ALLOCA | |
771 | #define LIB_STANDARD -lPW -lc | |
772 | in the `src/m/MACHINENAME.h' file for the machine. | |
773 | ||
774 | If you find that the character Meta-DEL makes Emacs crash, | |
775 | find where function init_sys_modes in sysdep.c sets sg.c_cc[VQUIT] | |
776 | and make it store 7 there. I have as yet no evidence of whether | |
777 | this problem, known in HP-UX, exists in other system V versions. | |
778 | ||
779 | System V rel 2.2 (usg5.2.2) | |
780 | ||
781 | In 5.2.2 AT&T undid, incompatibly, their previous incompatible | |
782 | change to the way the nlist library is called. A different s- file | |
783 | is used to enable the other interface. | |
784 | ||
785 | They call themselves the right choice--can't they choose? | |
786 | ||
787 | Emacs version 18 unexec is currently not working properly | |
788 | on 5.2.2. Nobody knows why yet. A workaround is to define | |
789 | NO_REMAP. It is not yet known whether this applies to all | |
790 | machines running 5.2.2. | |
791 | ||
792 | System V rel 3 (usg5.3) | |
793 | ||
794 | Some versions of this system support ptys and BSD-style sockets. | |
795 | On such systems, you should define HAVE_PTYS and HAVE_SOCKETS in config.h. | |
796 | ||
797 | If you want to link Emacs with shared libraries, define | |
798 | USG_SHARED_LIBRARIES. | |
799 | ||
da33ff57 JB |
800 | You may have to add ANSI idempotence #-lines to your sys/types.h |
801 | file to get Emacs to compile correctly. This may be necessary on | |
802 | other pre-ANSI systems as well. | |
cbd6b57c | 803 | |
da33ff57 JB |
804 | On an AT&T 6386WGS using System V Release 3.2 and X11R3, the X support |
805 | cannot be made to work. Whether or not the GNU relocating malloc is | |
806 | used, the symptom is that the first call Emacs makes to sbrk(0) returns | |
807 | (char *)-1. Sorry, you're stuck with character-only mode. Try | |
808 | installing Xfree86 to fix this. | |
809 | ||
810 | System V rel 4.0.3 and 4.0.4 (usg5.4) | |
811 | ||
812 | Supported, including shared libraries for ELF, but ptys do not work | |
813 | because TIOCGPGRP fails to work on ptys (but Dell 2.2 seems to have | |
814 | fixed this). This failure is probably due to a misunderstanding of | |
815 | the consequences of the POSIX spec: many system designers mistakenly | |
cbd6b57c JB |
816 | think that POSIX requires this feature to fail. This is untrue; |
817 | ptys are an extension, and POSIX says that extensions *when used* | |
818 | may change the action of standard facilities in any fashion. | |
819 | ||
da33ff57 JB |
820 | The standard C preprocessor may generate xmakefile incorrectly. However, |
821 | /lib/cpp will work, so use `make CPP=/lib/cpp'. Standard cpp | |
822 | seems to work OK under Dell 2.2. | |
cbd6b57c | 823 | |
da33ff57 | 824 | Some versions 3 and earlier of V.4, on the Intel 386 and 860, had |
cbd6b57c JB |
825 | problems in the X11 libraries. These prevent Emacs from working |
826 | with X. You can use Emacs with X provided your copy of X is based | |
da33ff57 JB |
827 | on X11 release 4 or newer, or is Dell's 2.2 (which is a 4.0.3). |
828 | Unfortunately, the only way you can tell whether your X11 library is | |
829 | new enough is to try compiling Emacs to use X. If emacs runs, your | |
830 | X11 library is new enough. | |
cbd6b57c JB |
831 | |
832 | In this context, GSV4 and GSV4i are alternate names for X11R4. | |
833 | OL2.* is X11R3 based. OL3 is in between X11R3 and X11R4, and may or | |
834 | may not work, depending on who made the Unix system. If the library | |
835 | libXol is part of the X distribution, then you have X11R3 and Emacs | |
836 | won't work with X. | |
837 | ||
838 | Most versions of V.4 support sockets. If `/usr/lib/libsocket.so' | |
839 | exists, your system supports them. If yours does not, you must add | |
840 | #undef HAVE_SOCKETS in config.h, after the inclusion of s-usg5-4.h. | |
841 | (Any system that supports Internet should implement sockets.) | |
842 | ||
843 | Ultrix (bsd4.3) | |
844 | ||
845 | Recent versions of Ultrix appear to support the features of Berkeley 4.3. | |
846 | Ultrix was at the BSD 4.2 level for a long time after BSD 4.3 came out. | |
847 | ||
848 | Ultrix 3.0 has incompatibilities in its X library if you have the | |
849 | Ultrix version of X (UWS version 2.0). To solve them, you need to | |
850 | prevent XvmsAlloc.o in Xlib from being used. Israel Pinkas says: | |
851 | ||
852 | I added the following lines to config.h after the X defines: | |
853 | ||
854 | #if defined(ultrix) && defined(X11) | |
855 | #define OBJECTS_SYSTEM calloc.o | |
856 | #endif | |
857 | ||
858 | Then I ran the following: | |
859 | ||
860 | ar x /usr/lib/libc.a calloc.o | |
861 | ||
862 | The problem is said to be gone in UWS version 2.1. | |
863 | ||
864 | Uniplus 5.2 (unipl5.2) | |
865 | ||
866 | Works, on Dual machines at least. | |
867 | ||
868 | VMS (vmsM.N) | |
869 | ||
cbd6b57c JB |
870 | The config file s/vms5-5.h may be right for some earlier versions; |
871 | please let us know what happens when you try it in VMS versions 5.0 | |
872 | thru 5.4. | |
873 | ||
874 | Note that Emacs for VMS is usually distributed in a special VMS | |
875 | distribution. See the file ../vms/VMSINSTALL for info on moving | |
876 | Unix distributions to VMS, and other VMS-related topics. | |
877 | ||
878 | Xenix (xenix) | |
879 | ||
880 | Should work in 18.50, but you will need to edit the files | |
881 | `lib-src/Makefile' and `src/ymakefile' | |
882 | (see the comments that mention "Xenix" for what to change.) | |
883 | Compiling Emacs with -O is said not to work. | |
884 | ||
885 | If you want Emacs to work with Smail (installed as /usr/bin/smail) | |
886 | then add the line #define SMAIL to config.h. | |
887 | ||
888 | The file etc/XENIX suggests some useful things to do to Xenix | |
889 | to make the Emacs meta key work. | |
