etc/MACHINES

   1 This is a list of the status of GNU Emacs on various machines and systems.
   2 Last updated 10 Feb 1992.
   3
   4 For each system and machine, we give the `-opsystem' and `-machine'
   5 options you should pass to configure to prepare to build Emacs for
   6 that system/machine.
   7
   8 These options tell Emacs which machine- and system-descriptive files
   9 to include.  For each `-machine=MACHNAME' option, there exists a file
  10 `src/m/MACHNAME.h', and for each `-opsystem=OSNAME' option, there
  11 exists a file `src/s/OSNAME.h'.
  12
  13 Systems:
  14
  15 Berkeley 4.1 (-opsystem=bsd4-1)
  16
  17   Works on vaxes.
  18
  19 Berkeley 4.2 (-opsystem=bsd4-2)
  20
  21   Works on several machines.
  22
  23 Berkeley 4.3 (-opsystem=bsd4-3)
  24
  25   Works, on Vaxes at least.
  26
  27 Microport
  28
  29   See under "Intel 386".
  30
  31 System V rel 0 (-opsystem=usg5-0)
  32
  33   Works, on Vaxes and 3bxxx's.
  34   There are some problems in 18.37 due to shortnames/cccp problems:
  35   use the emacs 17 cpp if you have it.
  36
  37 System V rel 2 (-opsystem=usg5-2)
  38
  39   Works on various machines.
  40   On some (maybe all) machines the library -lPW exists and contains
  41   a version of `alloca'.  On these machines, to use it, put
  42      #define HAVE_ALLOCA
  43      #define LIB_STANDARD -lPW -lc
  44   in the src/m/MACHINENAME.h file for the machine.
  45
  46   If you find that the character Meta-DEL makes Emacs crash,
  47   find where function init_sys_modes in sysdep.c sets sg.c_cc[VQUIT]
  48   and make it store 7 there.  I have as yet no evidence of whether
  49   this problem, known in HP-UX, exists in other system V versions.
  50
  51 System V rel 2.2 (-opsystem=usg5-2-2)
  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 System V rel 3 (-opsystem=usg5-3)
  65
  66   Some versions of this system support ptys and BSD-style sockets.
  67   On such systems, you should define HAVE_PTYS and HAVE_SOCKETS in config.h.
  68
  69   If you want to link Emacs with shared libraries, define
  70   USG_SHARED_LIBRARIES.
  71
  72 System V rel 4 (-opsystem=usg5-4)
  73
  74   Supported, including shared libraries for ELF, but ptys do not
  75   work because TIOCGPGRP fails to work on ptys.
  76   This failure is probably due to a misunderstanding of the
  77   consequences of the POSIX spec: many system designers mistakenly
  78   think that POSIX requires this feature to fail.  This is untrue;
  79   ptys are an extension, and POSIX says that extensions *when used*
  80   may change the action of standard facilities in any fashion.
  81
  82   The standard C preprocessor generate xmakefile incorrectly.  However,
  83   /lib/cpp will work, so use `make CPP=/lib/cpp'.
  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   whether your X11 library is new enough is to try compiling Emacs to
  90   use X.  If xemacs runs, your X11 library is new enough.
  91
  92   In this context, GSV4 and GSV4i are alternate names for X11R4.
  93   OL2.* is X11R3 based.  OL3 is in between X11R3 and X11R4, and may or
  94   may not work, depending on who made the Unix system.  If the library
  95   libXol is part of the X distribution, then you have X11R3 and Emacs
  96   won't work with X.
  97
  98   Most versions of V.4 support sockets.  If `/usr/lib/libsocket.so'
  99   exists, your system supports them.  If yours does not, you must add
 100   #undef HAVE_SOCKETS in config.h, after the inclusion of s-usg5-4.h.
 101   (Any system that supports Internet should implement sockets.)
 102
 103 Ultrix (-opsystem=bsd4-2)
 104
 105   Recent versions of Ultrix appear to support the features of Berkeley 4.3.
 106   Ultrix was at the BSD 4.2 level for a long time after BSD 4.3 came out.
 107
 108   Ultrix 3.0 has incompatibilities in its X library if you have the
 109   Ultrix version of X (UWS version 2.0).  To solve them, you need to
 110   prevent XvmsAlloc.o in Xlib from being used.  Israel Pinkas says:
 111
 112     I added the following lines to config.h after the X defines:
 113
 114     #if defined(ultrix) && defined(X11)
 115     #define OBJECTS_SYSTEM calloc.o
 116     #endif
 117
 118     Then I ran the following:
 119
 120     ar x /usr/lib/libc.a calloc.o
 121
 122   The problem is said to be gone in UWS version 2.1.
 123
 124 Uniplus 5.2 (-opsystem=unipl5-2)
 125
 126   Works, on Dual machines at least.
 127
 128 VMS (-opsystem=vmsM.N)
 129
 130   Works except for certain features (directory listing, dired,
 131   sending and receiving mail) that use synchronous subprocesses.
 132   We need people to write alternative implementations of these
 133   facilities.
 134
 135   The config file s/vms5-5.h may be right for some earlier versions;
 136   please let us know what happens when you try it in VMS versions 5.0 thru 5.4.
 137
 138   Note that Emacs for VMS is usually distributed in a special
 139   VMS distribution.  See the file ../VMSINSTALL for info on moving
 140   Unix distributions to VMS, and other VMS-related topics.
 141
 142 Xenix
 143
 144   Should work in 18.50, but you will need to edit the files
 145   lib-src/Makefile and src/ymakefile
 146   (see the comments that mention "Xenix" for what to change.)
 147   Compiling Emacs with -O is said not to work.
 148
 149   If you want Emacs to work with Smail (installed as /usr/bin/smail)
 150   then add the line   #define SMAIL  to config.h.
 151
 152   The file etc/XENIX suggests some useful things to do to Xenix
 153   to make the Emacs meta key work.
 154 \f
 155 Machines:
 156
 157 Alliant (-machine=alliant4, -machine=alliant or -machine=alliant1;
 158          -opsystem=bsd4-2)
 159
 160   18.52 works on system version 4.  Previous Emacs versions were
 161   known to work on previous system versions.
 162
 163   Use -machine=alliant1 on version 1 of their operating system
 164   and use -machine=alliant on version 2 or 3.
 165   Use -machine=alliant4 on version 4.
 166
 167 Alliant FX/2800 (-machine=alliant-2800; -opsystem=bsd4-3)
 168
 169   Known to work with 18.58 and OS version 2.2, compiler version 1.3.
 170
 171 Altos 3068 (-machine=altos; -opsystem=usg5-2)
 172
 173   18.52 is said to work, provided you don't compile unexec.c with -O.
 174
 175 Amdahl UTS (-machine=amdahl; -opsystem=usg5-2-2)
 176
 177   Small changes for 18.38 were merged in 18.39.  It is mostly
 178   working, but at last report a bug sometimes causes Emacs to
 179   grab very large amounts of memory.  No fix or explanation
 180   has yet been reported.  It may be possible to find this bug
 181   if you find which Emacs command it happens within and then
 182   run that command with a breakpoint set at malloc.
 183
 184   The 5.2u370 compiler is so brain damaged that it is not
 185   even worth trying to use it.  Success was obtained with the
 186   uts native C compiler on uts version 5.2.5.
 187
 188 Apollo running Domain (-machine=apollo; -opsystem=bsd4-2)
 189
 190   18.52 works, to some extent.
 191   Code for dumping Emacs has been written, but we cannot
 192   distribute it yet.
 193   There are reports of bugs in cc -O on this system.
 194
 195   In lib-src/Makefile, don't expect emacsclient and emacsserver to
 196   compile.  You might want to remove them from your makefile.
 197
 198   Supposedly something in dired.c runs into a compiler bug.
 199   Paraphrasing the statement should avoid the problem.  I have not yet
 200   received word as to the exact statement this is.
 201
 202 AT&T 3b2, 3b5, 3b15, 3b20 (-machine=att3b; -opsystem=usg5-2-2)
 203
 204   Emacs will probably not work with certain kernel constants too small.
 205
 206   In param.h CDLIMIT should be at least (1L << 12) in order to allow
 207   processes to write up to 2 Mbyte files.  If it's too small,
 208   you can perhaps fix it using the file `ulimit.hack' in this directory.
 209
 210   Note that for V.3.1 and later releases, this parameter is configurable
 211   by normal means in /etc/master.d/kernel; examine that file for the
 212   symbol CDLIMIT or ULIMIT, and raise it by several powers of 2.  Then
 213   do normal kernel rebuild things via "cd /boot; mkboot -k KERNEL" and so
 214   forth.  Do not use ulimit.hack if you have V.3.1 or later.
 215
 216   In seg.h NSEGP and STACKSEG should be at least 16 and 4 respectively
 217   to allow processes with total size of up to 2Mbytes.
 218   However, I'm told it is unlikely this would fail to be true.
 219
 220   The MAXMEM may also prevent Emacs from running.  The file
 221   3B-MAXMEM in this directory explains how to increase MAXMEM.
 222
 223 AT&T 7300 or 3b1 (-machine=7300; -opsystem=usg5-2-2)
 224
 225   18.52 seems to work.  If you have strange troubles with dumping
 226   Emacs, delete the last few lines from -machine=7300 and recompile.
 227   These lines are supposed to produce a sharable executable.
 228
 229   -machine=7300 defines SHORTNAMES because operating system versions
 230   older than 3.5 did not support long symbol names.  Version 3.5 does
 231   support them, so you can remove the #define SHORTNAMES in that
 232   version.
 233
 234 Bull sps7 (-machine=sps7; -opsystem=usg5-2)
 235
 236   Changes partially merged in version 19, but some fixes are probably required.
 237
 238 CCI 5/32, 6/32
 239
 240   See "Tahoe".
 241
 242 Celerity (-machine=celerity; -opsystem=bsd4-2)
 243
 244   Version 18.49 works.
 245
 246 Clipper (-machine=clipper; ???)
 247
 248   Version 19 has support for some brand of clipper system.
 249   Note that the Orion 105 is also a clipper, but some system-related
 250   parameters are different.
 251
 252 Convex (-machine=convex; -opsystem=bsd4-3)
 253
 254   18.53 is supposed to work.
 255
 256 Cubix QBx/386 (-machine=intel386; -opsystem=usg5-3)
 257
 258   Changes merged in 19.1.  Systems before 2/A/0 may fail to compile etags.c
 259   due to a compiler bug.
 260
 261 Cydra 5 (-machine=cydra5; -opsystem=usg5-3)
 262
 263   18.51 worked in one version of their operating system but stopped
 264   working in a newer version.  This has not been fixed.
 265
 266 DECstation (-machine=pmax; -opsystem=bsd4-3 or -opsystem=osf1)
 267
 268   OSF1 support merged in 18.59.
 269
 270   See under Ultrix for problems using X windows on Ultrix.
 271   Note that this is a MIPS machine.
 272   -opsystem=bsd4-3 is said to work ok with Ultrix 4.1.
 273
 274   For Ultrix versions prior to 4.0, you may need to delete
 275   the definition of START_FILES from src/m/pmax.h.
 276
 277 Motorola Delta 147 (-machine=delta; -opsystem=usg5-3)
 278
 279   Motorola Delta boxes running System V/68 release 3.
 280   (tested on sys1147 with SVR3V5).  Changes merged in 19.1.
 281
 282 Motorola Delta 187 (-machine=delta88k; -opsystem=usg5-3)
 283
 284   Machine support added in version 19.
 285   HAVE_X_MENU does not work due to lack of insque.
 286
 287 Dual running System V (-machine=dual; -opsystem=usg5-2)
 288
 289   As of 17.46, this works except for a few changes
 290   needed in unexec.c.
 291
 292 Dual running Uniplus (-machine=dual; -opsystem=unipl5-2)
 293
 294   Works, as of 17.51.
 295
 296 Elxsi 6400 (-machine=elxsi; -opsystem=usg5-2)
 297
 298   Changes for 12.0 release are in 19.1.
 299   Dumping should work now.
 300
 301 Encore machine (-machine=ns16000; -opsystem=umax)
 302
 303   This machine bizarrely uses 4.2BSD modified to use the COFF format
 304   for object files.  Works (as of 18.40).  For the APC processor you
 305   must enable two lines at the end of src/s/umax.h, which are commented
 306   out in the file as distributed.
 307
 308   WARNING: If you compile Emacs with the "-O" compiler switch, you
 309   must also use the "-q enter_exits" switch so that all functions have
 310   stack frames.  Otherwise routines that call `alloca' all lose.
 311
 312   A kernel bug in some system versions causes input characters to be lost
 313   occasionally.
 314
 315 GEC 93 (-machine=gec93; -opsystem=usg5-2?)
 316
 317   Changes are partially merged in version 18, but
 318   certainly require more work.
 319
 320 Gould Power Node (-machine=gould; -opsystem=bsd4-2 or -opsystem=bsd4-3)
 321
 322   18.36 worked on versions 1.2 and 2.0 of the operating system.
 323
 324   On UTX/32 2.0, use -opsystem=bsd4-3.
 325
 326   On UTX/32 1.2 and UTX/32S 1.0, use -opsystem=bsd4-2 and note that
 327   compiling lib-src/sorted-doc tickles a compiler bug: remove the -g
 328   flag to cc in the makefile.
 329
 330   UTX/32 1.3 has a bug in the bcopy library routine.  Fix it by
 331   #undef BSTRING in -machine=gould.
 332
 333   Version 19 incorporates support for releases 2.1 and later of UTX/32.
 334   A site running a pre-release of 2.1 should #define RELEASE2_1 in config.h.
 335
 336 Gould NP1 (-machine=gould-np1; -opsystem=bsd4-3)
 337
 338   Version 19 supposedly works.
 339
 340 Honeywell XPS100 (-machine=xps100; -opsystem=usg5-2)
 341
 342   Config file added in version 19.
 343
 344 HP 9000 series 200 or 300 (-machine=hp9000s300;
 345                            -opsystem=hpux or -opsystem=bsd4-3)
 346
 347   Version 18 works.
 348   These machines are 68000-series CPUs running HP-UX
 349   (a derivative of sysV with some BSD features) or BSD 4.3 ported by Utah.
 350   The choice of s- file determines which system Emacs is built for.
 351
 352   Series 200 HPUX runs Emacs only if it has the "HP-UX upgrade".
 353
 354   If you are running HP-UX release 8.0 or later, you need the optional
 355   "C/ANSI C" software in order to build Emacs (older releases of HP-UX
 356   do not require any special software).  If the file "/etc/filesets/C"
 357   exists on your machine, you have this software, otherwise you do not.
 358
 359   Note that HP has used two incompatible assembler syntaxes,
 360   and has recently changed the format of C function frames.
 361   src/crt0.c and src/alloca.s have been conditionalised for the new
 362   assembler and new function-entry sequence.  You may need to define
 363   OLD_HP_ASSEMBLER if you are using an older hpux version.  If you
 364   have an official (bought from HP) series 300 machine you have
 365   the new assembler.  Kernels that are 5.+ or later have new
 366   assembler.  A Series 200 that has been upgraded to a 68010
 367   processor and a 5.+ kernel has the new compiler.
 368
 369   Define C_SWITCH_MACHINE to be +X to make a version of Emacs that
 370   runs on both 68010 and 68020 based hp-ux's.
 371
 372   Define HPUX_68010 if you are using the new assembler, for
 373   a system that has a 68010 without a 68881.  This is to say,
 374   a s200 (upgraded) or s310.
 375
 376   Define the symbol HPUX_NET if you have the optional network features
 377   that include the `netunam' system call.  This is refered to as
 378   Network Services (NS/9000) in HP literature.
 379
 380 HP 9000 series 300 running BSD 4.3 (-machine=hp300bsd; -opsystem=bsd4-3)
 381
 382   Version 19.1 works.
 383
 384 HP 9000 series 500: not supported.
 385
 386   The series 500 has a seriously incompatible memory architecture
 387   which relocates data in memory during execution of a program,
 388   and support for it would be difficult to implement.
 389
 390 HP 9000 series 800 (Spectrum) (-machine=hp9000s800; -opsystem=hpux)
 391
 392   These files support HP's Precision Architecture machines
 393   running HP-UX.  It has been moderately tested on the Series
 394   840.
 395
 396   If you are running HP-UX release 8.0 or later, you need the optional
 397   "C/ANSI C" software in order to build Emacs (older releases of HP-UX
 398   do not require any special software).  If the file "/etc/filesets/C"
 399   exists on your machine, you have this software, otherwise you do not.
 400
 401 High Level Hardware Orion (-machine=orion; -opsystem=bsd4-2)
 402
 403   This is the original microprogrammed hardware.
 404   Machine description file ought to work.
 405
 406 High Level Hardware Orion 1/05 (-machine=orion105; -opsystem=bsd4-2)
 407
 408   Changes merged in 18.52.  This is the one with the Clipper cpu.
 409   Note that systems which lack NFS need LOAD_AVE_TYPE changed to `double'.
 410
 411   C compiler has a bug; it loops compiling eval.c.
 412   Compile it by hand without optimization.
 413
 414 IBM PS/2 (-machine=ibmps2-aix; -opsystem=usg5-2-2 or -opsystem=usg5-3)
 415
 416   Changes merged in version 19.  You may need to copy
 417   /usr/lib/samples/hft/hftctl.c to the Emacs src directory.
 418
 419   Use -opsystem=usg5-3 on AIX 1.2.
 420   -opsystem=usg5-2-2 should work on either AIX 1.1 or 1.2, but may not
 421   work with certain new X window managers, and may be suboptimal.
 422
 423 IBM RS/6000 (-machine=ibmrs6000; -opsystem=aix3-1)
 424
 425   Changes merged in version 19.  Currently the configuration
 426   does not actually depend on the version of AIX.
 427
 428   Compiling with -O using the IBM compiler has been known
 429   to make Emacs work incorrectly.
 430
 431 IBM RT/PC (-machine=ibmrt or -machine=ibmrt-aix;
 432            -opsystem=bsd4-2 or -opsystem=usg5-2-2)
 433
 434   18.52 works on both operating systems.
 435   Use -opsystem=bsd4-2 for the 4.2-like system and -opsystem=usg5-2-2
 436   for AIX.
 437
 438   On BSD, if you have trouble, try compiling with a different compiler.
 439
 440   On AIX, the file /usr/lib/samples/hft/hftctl.c must be compiled into
 441   hftctl.o, with this result left in the src directory (hftctl.c is
 442   part of the standard AIX distribution).
 443
 444   window.c must not be compiled with -O on AIX.
 445
 446 Integrated Solutions `Optimum V' (-machine=isi-ov;
 447                                   -opsystem=bsd4-2 or -opsystem=bsd4-3)
 448
 449   18.52 said to work on some sort of ISI machine.
 450   Version 18.45 worked (running on a Optimum V (VME bus, 68020)
 451   BSD 4.2 (3.05e) system).  18.42 is reported to work on
 452   a Qbus 68010 system.  Has not been tried on `WorkStation' `Cluster
 453   Compute Node' `Cluster WorkStation' or `Server Node'  (Love the
 454   StudLYCaps)
 455
 456   Compilation with -O is rumored to break something.
 457
 458   On recent system versions, you may need to undefine the macro UMAX
 459   in lib-src/loadst.c and src/getpagesize.h.  They stupidly defined this
 460   in a system header file, which confuses Emacs (which thinks that UMAX
 461   indicates the Umax operating system).
 462
 463 Intel 386 (-machine=intel386 or -machine=is386;
 464            -opsystem=bsd4-2, usg5-2-2, usg5-3, isc2-2, 386-ix,
 465                      esix, or xenix)
 466
 467   18.58 should support a wide variety of operating systems.
 468   Use -opsystem=isc2-2 for Interactive 386/ix version 2.2.
 469   Use -opsystem=386ix for prior versions.
 470   Use -opsystem=esix for Esix.
 471   It isn't clear what to do on an SCO system.  The system's C
 472   preprocessor doesn't seem to handle the src subdirectory's Make
 473   trickery, so you will probably need to install the GNU C preprocessor.
 474
 475   If you are using Xenix, see notes above under Xenix.
 476
 477   Some sysV.3 systems seem to have bugs in `opendir';
 478   for them, alter `config.h' to define NONSYSTEM_DIR_LIBRARY
 479   and undefine SYSV_SYSTEM_DIR.
 480
 481   If you use optimization on V.3, you may need the option -W2,'-y 0'
 482   to prevent certain faulty optimization.
 483
 484   On 386/ix, to link with shared libraries, add #define USG_SHARED_LIBRARIES
 485   to config.h.
 486
 487   There is no consistency in the handling of certain system header files
 488   on V.3.
 489
 490   Some versions have sys/sioctl.h, and require it in sysdep.c.
 491   But some versions do not have sys/sioctl.h.
 492   For a given version of the system, this may depend on whether you have
 493   X Windows or TCP/IP.  Define or undefine NO_SIOCTL_H in config.h
 494   according to whether you have the file.
 495
 496   Likewise, some versions have been known to need sys/ttold.h, sys/stream.h,
 497   and sys/ptem.h included in sysdep.c.  If your system has these files,
 498   try defining NEED_PTEM_H in config.h if you have trouble without it.
 499
 500   You may find that adding -I/usr/X/include or -I/usr/netinclude or both
 501   to CFLAGS avoids compilation errors on certain systems.
 502
 503   Some versions convince sysdep.c to try to use `struct tchars'
 504   but define `struct tc' instead; add `#define tchars tc'
 505   to config.h to solve this problem.
 506
 507   The file -machine=is386 is used for an Integrated Solutions 386 machine.
 508   It may also be correct for Microport systems.
 509
 510 Iris 2500 (-machine=irist; -opsystem=iris3-5 or -opsystem=iris3-6)
 511
 512   Version 18 said to work; use -opsystem=irist3-5 for system version 2.5
 513   and -opsystem=iris3-6 for system version 3.6.
 514
 515 Iris 2500 Turbo (-machine=irist; -opsystem=iris3-5 or -opsystem=iris3-6)
 516
 517   18.49 works.  Use -opsystem=iris3-6 for system versions 3.6 and up.
 518   Note that the 3030 is the same machine as this.
 519
 520 Iris 4D (-machine=iris4d; -opsystem=irix3-3)
 521
 522   18.56 is known to work on 4D series machines with Irix 3.3 or later.
 523
 524   If you use the X menu facility, you must edit oldXmenu/Makefile
 525   to add the line
 526
 527     RANLIB=true
 528
 529   Someone said that with the yellow pages you must change two definitions
 530   in -machine=iris4d as follows:
 531
 532     #define LIBS_MACHINE -lsun -lbsd -lPW -lmld
 533     #define C_SWITCH_MACHINE -I/usr/include/sun -I/usr/include/bsd
 534
 535   jg@bambi.esd.sgi.com says this isn't true anymore,
 536   but the info might as well be here just in case.

 540   We are boycotting Apple because of Apple's efforts to take away
 541   our freedom to write compatible imitations of existing software.
 542   If you value your freedom to write such programs, we urge you
 543   not to buy from Apple, not to develop software for Apple, and
 544   certainly not to accept a job with Apple.
 545
 546   See the file APPLE in this directory for more information.
 547
 548 Masscomp (-machine=masscomp; -opsystem=rtu)
 549
 550   18.36 worked on a 5500DP running RTU v3.1a and compiler version 3.2
 551   with minor fixes that are included in 18.37.  However, bizarre behavior
 552   was reported for 18.36 on a Masscomp (model and version unknown but probably
 553   a 68020 system).  The report sounds like a compiler bug.
 554
 555   A compiler bug affecting statements like
 556     unsigned char k; unsigned char *p;... x = p[k];
 557   has been reported for "C version 1.2 under RTU 3.1".  We do not wish
 558   to take the time to install the numerous workarounds required to
 559   compensate for this bug; go complain to Masscomp.
 560
 561   For RTU version 3.1, define FIRST_PTY_LETTER to be 'p' in src/s/rtu.h
 562   (or #undef and redefine it in config.h) so that ptys will be used.
 563
 564   GNU Emacs is said to have no chance of compiling on RTU versions
 565   prior to v3.0.
 566
 567 Megatest (-machine=mega68; -opsystem=bsd4-2)
 568
 569   Emacs 15 worked; do not have any reports about Emacs 16 or 17
 570   but any new bugs are probably not difficult.
 571
 572 Mips (-machine=mips or -machine=mips4; -opsystem=usg5-2-2, -opsystem=bsd4-3)
 573
 574   Changes merged in 18.39.  Some fixes in 18.56.
 575
 576   Use -machine=mips4 for RISCOS version 4; use -opsystem=bsd4-3 with
 577   the BSD world.
 578
 579   Note that the proper -machine option for the Decstation is `-machine=pmax'.
 580
 581   If you are compiling with GCC, then you must run fixincludes;
 582   the alternative of using -traditional won't work because
 583   the definition of SIGN_EXTEND_CHAR uses the keyword `signed'.
 584
 585   If the SYSV world is the default, then you probably need the following
 586   line in etc/Makefile:
 587
 588     CFLAGS= -g -systype bsd43
 589
 590   Some operating systems on MIPS machines give SIGTRAP for division by
 591   zero instead of the usual signals.  The only real solution is to fix
 592   the system to give a proper signal.
 593
 594   In the meantime, you can change init_data in data.c if you wish.
 595   Change it to handle SIGTRAP as well as SIGFPE.  But this will have a
 596   great disadvantage: you will not be able to run Emacs under a
 597   debugger.  I think crashing on division by zero is a lesser problem.
 598
 599 Motorola Delta (-machine=delta; -opsystem=usg5-3)
 600
 601   Machine support added in version 18.56.
 602
 603 National Semiconductor 32000 (-machine=ns32000; -opsystem=usg5-2)
 604
 605   This is for a complete machine from National Semiconductor,
 606   running Genix.  Changes merged in version 19.
 607
 608 NCR Tower 32 running System V release 2 (-machine=tower32; -opsystem=usg5-2-2)
 609
 610   Works as of 17.56.  If you change src/ymakefile so that CFLAGS includes
 611   C_OPTIMIZE_SWITCH rather than C_DEBUG_SWITCH, check out the comments
 612   in src/m/tower32.h about this.
 613
 614   There is a report that compilation with -O did not work with 18.54.
 615
 616 NCR Tower 32 running System V release 3 (-machine=tower32v3; -opsystem=usg5-3)
 617
 618   Works as of 18.56.  If you change src/ymakefile so that CFLAGS includes
 619   C_OPTIMIZE_SWITCH rather than C_DEBUG_SWITCH, and do not use gcc, check
 620   out the comments in src/m/tower32v3.h about this.
 621
 622 Nixdorf Targon 31 (-machine=targon31; -opsystem=usg5-2-2)
 623
 624   Machine description file for version 17 is included in 18
 625   but whether it works is not known.
 626   src/unexec.c bombs if compiled with -O.
 627   Note that the "Targon 35" is really a Pyramid.
 628
 629 Nu (TI or LMI) (-machine=nu; -opsystem=usg5-2)
 630
 631   Version 18 is believed to work.
 632
 633 Plexus (-machine=plexus; -opsystem=usg5-2)
 634
 635   Works as of 17.56.
 636
 637 Pmax (DEC Mips)  (-machine=pmax; -opsystem=bsd4-2)
 638
 639   See under DECstation, above.
 640
 641 Prime EXL (-machine=intel386; -opsystem=usg5-3)
 642
 643   Minor changes merged in 19.1.
 644
 645 Pyramid (-machine=pyramid; -opsystem=bsd4-2)
 646
 647   You need to build Emacs in the Berkeley universe with
 648   the `ucb' command, as in `ucb make' or `ucb build-install'.
 649
 650   In OSx 4.0, it seems necessary to add the following two lines
 651   to src/m/pyramid.h:
 652      #define _longjmp longjmp
 653      #define _setjmp setjmp
 654
 655   In Pyramid system 2.5 there has been a compiler bug making
 656   Emacs crash just after screen-splitting with Qnil containing 0.
 657   A compiler that fixes this is Pyramid customer number 8494,
 658   internal number 1923.
 659
 660   Some versions of the pyramid compiler get fatal
 661   errors when the -gx compiler switch is used; if this
 662   happens to you, change src/m/pyramid.h to define
 663   C_DEBUG_SWITCH with an empty definition.
 664
 665   Some old system versions may require you to define PYRAMID_OLD
 666   in when alloca.s is preprocessed, in order to define _longjmp and _setjmp.
 667
 668 Sequent Balance (-machine=sequent;
 669                  -opsystem=bsd4-2, or -opsystem=bsd4-3 on newer systems)
 670
 671   Emacs 18.51 should work on system version 3.0.  18.52 is said to work.
 672   Delete some lines at the end of src/m/sequent.h for earlier system
 673   versions.
 674
 675 Sequent Symmetry (-machine=symmetry; -opsystem=bsd4-3)
 676
 677   Emacs 19 should work.
 678
 679 SONY News (-machine=news;
 680            -opsystem=bsd4-2, or -opsystem=bsd4-3 for system release 3)
 681
 682   18.52 should work.
 683
 684 SONY News 3000 series (RISC NEWS) (-machine=news-risc; -opsystem=bsd4-3)
 685
 686   Works, as of 18.56.  Note that this is a MIPS architecture machine.
 687
 688   Some versions of the operating system give SIGTRAP for division by zero
 689   instead of the usual signals.  This causes division by zero
 690   to make Emacs crash.  The system should be fixed to give the proper signal.
 691   Changing Emacs is not a proper solution, because it would prevent
 692   Emacs from working under any debugger.  But you can change init_data
 693   in data.c if you wish.
 694
 695 Stardent 1500 or 3000
 696
 697   See Titan.
 698
 699 Stride (-machine=stride; -opsystem=usg5-2)
 700
 701   Works (most recent news for 18.30) on their release 2.0.
 702   For release 2.2, see the end of src/m/stride.h.
 703   It may be possible to run on their V.1 system but changes
 704   in the s- file would be needed.
 705
 706 Sun 1, 2 and 3 (-machine=sun1, -machine=sun2, -machine=sun3;
 707                 -opsystem=bsd4-2, sunos4-0, or sunos4-1)
 708
 709   There are three machine files for different versions of SunOS.
 710   All are derived from Berkeley 4.2.  Emacs 17 has run on all of them.
 711   Whether you should use -machine=sun1, -machine=sun2 or -machine=sun3
 712   depends on the VERSION OF THE OPERATING SYSTEM you have.
 713   You will need to use -machine=sun3 on Sun 2's running SunOS release 3.
 714
 715   For SunOS release 4 on a Sun 3, use -machine=sun3 and
 716   -opsystem=sunos4-0 or -opsystem=sunos4-1.
 717   See the file etc/SUNBUG for how to solve problems caused by
 718   bugs in the "export" version of SunOS 4.
 719
 720   If you have trouble using open-network-stream, get the
 721   distribution of `bind' (the BSD name-server), build libresolv.a,
 722   and link Emacs with -lresolv.  This problem is due to obsolete
 723   software in the nonshared standard library.
 724
 725   If you want to use SunWindows, define HAVE_SUN_WINDOWS
 726   in config.h to enable a special interface called `emacstool'.
 727   The definition must *precede* the #include "machine.h".
 728   System version 3.2 is required for this facility to work.
 729
 730   We recommend that you instead use the X window system, which
 731   has technical advantages, is an industry standard, and is also
 732   free software.
 733
 734   If you are compiling for X windows, and the X window library was
 735   compiled to use the 68881, then you must edit config.h according
 736   the comments at the end of -machine=sun3.
 737
 738   Note that Emacs on a Sun is not really as big as it looks.
 739   As dumped, it includes around 200k of zeros between the
 740   original text section and the original data section
 741   (now remapped as part of the text).  These are never
 742   swapped in.
 743
 744   To build a single Emacs that will run on Sun 2 and Sun 3
 745   HARDWARE, just build it on the Sun 2.
 746
 747 Sun 4 (-machine=sparc;
 748        -opsystem=bsd4-2, -opsystem=sunos4-0, -opsystem=sunos4-1)
 749
 750   Changes merged in 18.50.  Some people say optimizing compilation
 751   does not work; some say that -O2 (whatever that is) works
 752   perhaps with a small change.
 753
 754   Use -opsystem=sunos4-0 for operating system version 4.0, and
 755   -opsystem=sunos4-1 for later versions.
 756   See the file etc/SUNBUG for how to solve problems caused by
 757   bugs in the "export" version of SunOS 4.
 758
 759 Sun Roadrunner (-machine=sun386; -opsystem=sunos4-0 or -opsystem=sunos4-1)
 760
 761   Changes merged in 18.51.
 762
 763 Tadpole 68K (-machine=tad68k; -opsystem=usg5-3)
 764
 765   Changes merged in 19.1.
 766
 767   You may need to edit Makefile to change the variables LIBDIR and
 768   BINDIR from /usr/local to /usr/contrib.
 769
 770   To give movemail access to /usr/mail, you may need to execute
 771
 772     chmod 2755 etc/movemail; chgrp mail etc/movemail
 773
 774 Tahoe (-machine=tahoe; -opsystem=bsd4-2 or -opsystem=bsd4-3)
 775
 776   18.52 known to work on some Tahoes, but a compiler bug intervenes
 777   on others.  Some Emacs versions have worked in Unisys 1r4
 778   (not in 1r3) and CCI I.21.
 779
 780   If you have trouble compiling lib-src/loadst.c, turn off the definition
 781   of DKSTAT_HEADER_FILE in -machine=tahoe.
 782
 783 Tandem Integrity S2 (-machine=tandem-s2; -opsystem=usg5-3)
 784
 785   Changes merged in 18.56 but subprocess support is turned off.
 786   You will probably want to see if you can make subprocesses work.
 787
 788   You must edit lib-src/Makefile to define LOADLIBES = -mld.
 789
 790 Tektronix 16000 box (6130?) (-machine=ns16000; -opsystem=bsd4-2)
 791
 792   Emacs 17.61 worked.
 793
 794 Tektronix 4300 (-machine=tek4300; -opsystem=bsd4-3)
 795
 796   Emacs 18.51 should work.
 797
 798 Titan P2 or P3 (-machine=titan; -opsystem=usg5-3)
 799
 800   Changes probably merged in version 19.
 801
 802 Ustation E30 (SS5E) (-machine=ustation; -opsystem=unipl5-2).
 803
 804   Changes merged in 18.52; don't know whether they work.
 805
 806 Vax running Berkeley Unix (-machine=vax;
 807                            -opsystem=bsd4-1, bsd4-2 or bsd4-3)
 808
 809   Works.
 810
 811 Vax running Ultrix (-machine=vax; -opsystem=bsd4-2)
 812
 813   Works.  See under Ultrix for problems using X windows on Ultrix.
 814
 815 Vax running System V rel 2 (-machine=vax; -opsystem=usg5-2)
 816
 817   18.27 Works.
 818
 819 Vax running System V rel 0 (-machine=vax; -opsystem=usg5-0)
 820
 821   Works as of 18.36.
 822
 823 Vax running VMS (-machine=vax; -opsystem=vms
 824                  but on VMS they are m_vax.h and s_vms.h)
 825
 826   18.36 believed to work.  Addition of features is necessary to make
 827   this Emacs version more usable.
 828
 829 Whitechapel MG1 (-machine=mg1, s-?)
 830
 831   May work.  Supposedly no changes were needed except the m- file.
 832   I do not know what Unix version runs on them.
 833
 834 Wicat (-machine=wicat; -opsystem=usg5-2)
 835
 836   Changes merged as of 18.6; whether they work is unknown.
 837   See comments in src/m/wicat.h for things you should change
 838   depending on the system and compiler version you have.
