This is a list of the status of GNU Emacs on various machines and systems.
Last updated 14 October 1990.
Systems:
For each type of system, the name of the appropriate s- header file
is given.
Berkeley 4.1 (s-bsd4-1.h)
Works on vaxes.
Berkeley 4.2 (s-bsd4-2.h)
Works on several machines.
Berkeley 4.3 (s-bsd4-3.h)
Works, on Vaxes at least.
Microport
See under "Intel 386".
System V rel 0 (s-usg5-0.h)
Works, on Vaxes and 3bxxx's.
There are some problems in 18.37 due to shortnames/cccp problems:
use the emacs 17 cpp if you have it.
System V rel 2 (s-usg5-2.h)
Works on various machines.
On some (maybe all) machines the library -lPW exists and contains
a version of `alloca'. On these machines, to use it, put
#define HAVE_ALLOCA
#define LIB_STANDARD -lPW -lc
in the m-...h file for the machine.
If you find that the character Meta-DEL makes Emacs crash,
find where function init_sys_modes in sysdep.c sets sg.c_cc[VQUIT]
and make it store 7 there. I have as yet no evidence of whether
this problem, known in HP-UX, exists in other system V versions.
System V rel 2.2 (s-usg5-2-2.h)
In 5.2.2 AT&T undid, incompatibly, their previous incompatible
change to the way the nlist library is called. A different s- file
is used to enable the other interface.
They call themselves the right choice--can't they choose?
Emacs version 18 unexec is currently not working properly
on 5.2.2. Nobody knows why yet. A workaround is to define
NO_REMAP. It is not yet known whether this applies to all
machines running 5.2.2.
System V rel 3 (s-usg5-3.h)
Some versions of this system support ptys and BSD-style sockets.
On such systems, you should define HAVE_PTYS and HAVE_SOCKETS in config.h.
If you want to link Emacs with shared libraries, define
USG_SHARED_LIBRARIES.
System V rel 4 (s-usg5-4.h)
Supported, including shared libraries for ELF, but ptys do not
work because TIOCGPGRP fails to work on ptys.
This failure is probably due to a misunderstanding of the
consequences of the POSIX spec: many system designers mistakenly
think that POSIX requires this feature to fail.
Ultrix (s-bsd4-2.h)
DEC's Ultrix OS is essentially Berkeley 4.2. It does not correctly
implement certain features of 4.3.
Ultrix 3.0 has incompatibilities in its X library if you have the
Ultrix version of X (UWS version 2.0). To solve them, you need to
prevent XvmsAlloc.o in Xlib from being used. Israel Pinkas says:
I added the following lines to config.h after the X defines:
#if defined(ultrix) && defined(X11)
#define OBJECTS_SYSTEM calloc.o
#endif
Then I ran the following:
ar x /usr/lib/libc.a calloc.o
The problem is said to be gone in UWS version 2.1.
Uniplus 5.2 (s-unipl5-2.h)
Works, on Dual machines at least.
VMS (s-vms.h)
Works except for certain features (directory listing, dired,
sending and receiving mail) that use synchronous subprocesses.
We need people to write alternative implementations of these
facilities.
Note that Emacs for VMS is usually distributed in a special
VMS distribution. See the file ../VMSINSTALL for info on moving
Unix distributions to VMS, and other VMS-related topics.
Xenix
Should work in 18.50, but you will need to edit the files
etc/Makefile and src/ymakefile
(see the comments that mention "Xenix" for what to change.)
Compiling Emacs with -O is said not to work.
If you want Emacs to work with Smail (installed as /usr/bin/smail)
then add the line #define SMAIL to config.h.
The file etc/XENIX suggests some useful things to do to Xenix
to make the Emacs meta key work.
Machines:
For each type of machine, the names of the m- and s- header files
are given.
Alliant (m-alliant4.h or m-alliant.h or m-alliant1.h; s-bsd4-2.h)
18.52 works on system version 4. Previous Emacs versions were
known to work on previous system versions.
Use m-alliant1.h on version 1 of their operating system
and use m-alliant.h on version 2 or 3.
Use m-alliant4.h on version 4.
Altos 3068 (m-altos.h; s-usg5-2.h)
18.52 is said to work, provided you don't compile unexec.c with -O.
Amdahl UTS (m-amdahl.h; s-usg5-2-2.h)
Small changes for 18.38 were merged in 18.39. It is mostly
working, but at last report a bug sometimes causes Emacs to
grab very large amounts of memory. No fix or explanation
has yet been reported. It may be possible to find this bug
if you find which Emacs command it happens within and then
run that command with a breakpoint set at malloc.
The 5.2u370 compiler is so brain damaged that it is not
even worth trying to use it. Success was obtained with the
uts native C compiler on uts version 5.2.5.
Apollo running Domain (m-apollo.h; s-bsd4-2.h)
18.52 works, to some extent.
Code for dumping Emacs has been written, but we cannot
distribute it yet.
There are reports of bugs in cc -O on this system.
In etc/Makefile, don't expect emacsclient and emacsserver to
compile. You might want to remove them from your makefile.
Supposedly something in dired.c runs into a compiler bug.
Paraphrasing the statement should avoid the problem.
I havenot yet received word as to the exact statement this is.
AT&T 3b2, 3b5, 3b15, 3b20 (m-att3b.h; s-usg5-2-2.h)
Emacs will probably not work with certain kernel constants too small.
In param.h CDLIMIT should be at least (1L << 12) in order to allow
processes to write up to 2 Mbyte files. If it's too small,
you can perhaps fix it using the file `ulimit.hack' in this directory.
Note that for V.3.1 and later releases, this parameter is configurable
by normal means in /etc/master.d/kernel; examine that file for the
symbol CDLIMIT or ULIMIT, and raise it by several powers of 2. Then
do normal kernel rebuild things via "cd /boot; mkboot -k KERNEL" and so
forth. Do not use ulimit.hack if you have V.3.1 or later.
In seg.h NSEGP and STACKSEG should be at least 16 and 4 respectively
to allow processes with total size of up to 2Mbytes.
However, I'm told it is unlikely this would fail to be true.
The MAXMEM may also prevent Emacs from running. The file
3B-MAXMEM in this directory explains how to increase MAXMEM.
AT&T 7300 or 3b1 (m-7300.h; s-usg5-2-2.h)
18.52 seems to work. If you have strange troubles with dumping Emacs,
delete the last few lines from m-7300.h and recompile. These lines
are supposed to produce a sharable executable.
m-7300.h defines SHORTNAMES because operating system versions
older than 3.5 did not support long symbol names. Version 3.5 does
support them, so you can remove the #define SHORTNAMES in that version.
Bull sps7 (m-sps7.h; s-usg5-2.h)
Changes partially merged in version 19, but some fixes are probably required.
CCI 5/32, 6/32
See "Tahoe".
Celerity (m-celerity.h; s-bsd4-2.h)
Version 18.49 works.
Clipper (m-clipper.h; ???)
Version 19 has support for some brand of clipper system.
Note that the Orion 105 is also a clipper, but some system-related
parameters are different.
Convex (m-convex.h; s-bsd4-3.h)
18.53 is supposed to work.
Cubix QBx/386 (m-intel386.h; s-usg5-3.h)
Changes merged in 19.1. Systems before 2/A/0 may fail to compile etags.c
due to a compiler bug.
Cydra 5 (m-cydra5.h; s-usg5-3.h)
18.51 worked in one version of their operating system but stopped
working in a newer version. This has not been fixed.
DECstation (m-pmax.h; s-bsd4-2.h)
Works, as of 18.55. See under Ultrix for problems using X windows
on Ultrix. Note that this is a MIPS machine.
Delta (m-delta.h; s-usg5-3.h)
Motorola Delta boxes running System V/68 release 3.
(tested on sys1147 with SVR3V5). Changes merged in 19.1.
Dual running System V (m-dual.h; s-usg5-2.h)
As of 17.46, this works except for a few changes
needed in unexec.c.
Dual running Uniplus (m-dual.h; s-unipl5-2.h)
Works, as of 17.51.
Elxsi 6400 (m-elxsi; s-usg5-2.h)
Changes for 12.0 release are in 19.1.
Dumping should work now.
Encore machine (m-ns16000.h; s-umax.h)
This machine bizarrely uses 4.2BSD modified to use the COFF format
for object files. Works (as of 18.40). For the APC processor you
must enable two lines at the end of s-umax.h, which are commented
out in the file as distributed.
WARNING: If you compile Emacs with the "-O" compiler switch, you
must also use the "-q enter_exits" switch so that all functions have
stack frames. Otherwise routines that call `alloca' all lose.
A kernel bug in some system versions causes input characters to be lost
occasionally.
GEC 93 (m-gec93.h; s-usg5-2.h?)
Changes are partially merged in version 18, but
certainly require more work.
Gould Power Node (m-gould.h; s-bsd4-2.h or s-bsd4-3.h)
18.36 worked on versions 1.2 and 2.0 of the operating system.
On UTX/32 2.0, use s-bsd4-3.h.
On UTX/32 1.2 and UTX/32S 1.0, use s-bsd4-2.h and note that compiling
etc/sorted-doc tickles a compiler bug: remove the -g flag to cc in the
makefile.
UTX/32 1.3 has a bug in the bcopy library routine. Fix it by
#undef BSTRING in m-gould.h.
Version 19 incorporates support for releases 2.1 and later of UTX/32.
A site running a pre-release of 2.1 should #define RELEASE2_1 in config.h.
Gould NP1 (m-gould-np1.h; s-bsd4-3.h)
Version 19 supposedly works.
Honeywell XPS100 (m-xps100.h; s-usg5-2.h)
Config file added in version 19.
HP 9000 series 200 or 300 (m-hp9000s300.h; s-hpux.h or s-bsd4-3.h)
Version 18 works.
These machines are 68000-series CPUs running HP-UX
(a derivative of sysV with some BSD features) or BSD 4.3 ported by Utah.
The choice of s- file determines which system Emacs is built for.
Series 200 HPUX runs Emacs only if it has the "HP-UX upgrade".
Note that HP has used two incompatible assembler syntaxes,
and has recently changed the format of C function frames.
src/crt0.c and src/alloca.s have been conditionalised for the new
assembler and new function-entry sequence. You may need to define
OLD_HP_ASSEMBLER if you are using an older hpux version. If you
have an official (bought from HP) series 300 machine you have
the new assembler. Kernels that are 5.+ or later have new
assembler. A Series 200 that has been upgraded to a 68010
processor and a 5.+ kernel has the new compiler.
Define C_SWITCH_MACHINE to be +X to make a version of Emacs that
runs on both 68010 and 68020 based hp-ux's.
Define HPUX_68010 if you are using the new assembler, for
a system that has a 68010 without a 68881. This is to say,
a s200 (upgraded) or s310.
Define the symbol HPUX_NET if you have the optional network features
that include the `netunam' system call. This is refered to as
Network Services (NS/9000) in HP literature.
HP 9000 series 300 running BSD 4.3 (m-hp300bsd.h; s-bsd4-3.h)
Version 18.55 works.
HP 9000 series 500: not supported.
The series 500 has a seriously incompatible memory architecture
which relocates data in memory during execution of a program,
and support for it would be difficult to implement.
HP 9000 series 800 (Spectrum) (m-hp9000s800.h; s-hpux.h)
These files support HP's Precision Architecture machines
running HP-UX. It has been moderately tested on the Series
840.
High Level Hardware Orion (m-orion.h; s-bsd4-2.h)
This is the original microprogrammed hardware.
m- file ought to work.
High Level Hardware Orion 1/05 (m-orion105.h; s-bsd4-2.h)
Changes merged in 18.52. This is the one with the Clipper cpu.
Note that systems which lack NFS need LOAD_AVE_TYPE changed to `double'.
C compiler has a bug; it loops compiling eval.c.
Compile it by hand without optimization.
IBM PS/2 (m-ibmps2-aix.h; s-usg5-2-2.h)
Changes merged in version 19. You may need to copy
/usr/lib/samples/hft/hftctl.c to the Emacs src directory.
IBM RS/6000 (m-ibmrs6000.h; s-aix3-1.h)
Changes merged in version 19.
Note that Emacs can store the pure Lisp data in a shared segment on
this machine, but only if you put this command in one of the boot
scripts
emacs -batch -q
so that it is run as root when the machine is booted. This command
creates a read-only shared segment owned by root. Otherwise the
pure data is not shared. The pure data size is around 100K, which
may not be enough to matter for most users of this machine.
IBM RT/PC (m-ibmrt.h or m-ibmrt-aix.h; s-bsd4-2.h or s-usg5-2-2.h)
18.52 works on both operating systems.
Use s-bsd-4-2.h for the 4.2-like system and s-usg5-2-2.h for AIX.
On BSD, if you have trouble, try compiling with a different compiler.
On AIX, the file /usr/lib/samples/hft/hftctl.c must be compiled into
hftctl.o, with this result left in the src directory (hftctl.c is
part of the standard AIX distribution).
window.c must not be compiled with -O on AIX.
Integrated Solutions `Optimum V' (m-isi-ov.h; s-bsd4-2.h or s-bsd4-3.h)
18.52 said to work on some sort of ISI machine.
Version 18.45 worked (running on a Optimum V (VME bus, 68020)
BSD 4.2 (3.05e) system). 18.42 is reported to work on
a Qbus 68010 system. Has not been tried on `WorkStation' `Cluster
Compute Node' `Cluster WorkStation' or `Server Node' (Love the
StudLYCaps)
Compilation with -O is rumored to break something.
On recent system versions, you may need to undefine the macro UMAX
in etc/loadst.c and src/getpagesize.h. They stupidly defined this
in a system header file, which confuses Emacs (which thinks that UMAX
indicates the Umax operating system).
Intel 80386 (m-intel386.h or m-is386.h; s-bsd4-2.h, s-usg5-2-2.h, s-usg5-3.h,
s-386-ix.h or s-xenix.h)
Changes merged in 18.50 for all three operating systems.
If you are using Xenix, see notes above under Xenix.
Some sysV.3 systems seem to have bugs in `opendir';
for them, alter `config.h' to define NONSYSTEM_DIR_LIBRARY
and undefine SYSV_SYSTEM_DIR.
If you use optimization on V.3, you may need the option -W2,'-y 0'
to prevent certain faulty optimization.
There is no consistency in the handling of certain system header files
on V.3.
Some versions have sys/sioctl.h, and require it in sysdep.c.
But some versions do not have sys/sioctl.h.
Some versions have been known to need sys/ttold.h, sys/stream.h,
and sys/ptem.h included in sysdep.c.
Some versions convince sysdep.c to try to use `struct tchars'
but define `struct tc' instead; add `#define tchars tc'
to config.h to solve this problem.
The file m-is386.h is used for an Integrated Solutions 386 machine.
It may also be correct for Microport systems.
Iris 2500 (m-irist.h; s-iris3-5.h or s-iris3-6.h)
Version 18 said to work; use s-irist3-5.h for system version 2.5
and s-iris3-6.h for system version 3.6.
Iris 2500 Turbo (m-irist.h; s-iris3-5.h or s-iris3-6.h)
18.49 works. Use s-iris3-6.h for system versions 3.6 and up.
Note that the 3030 is the same machine as this.
Iris 4D (m-iris4d.h; s-iris3-6.h or s-irix3-3.h)
Changes for 18.49 are merged in 18.50. 18.52 seems to work.
The system version called Irix 3.3 is newer than what was called 3.6.
Note that the compilation of etc/loadst.c requires editing etc/Makefile.
See the comment in that file.
Someone says that with the yellow pages you must change two definitions
in m-iris4d.h as follows:
#define LIBS_MACHINE -lsun -lbsd -lPW -lmld
#define C_SWITCH_MACHINE -I/usr/include/sun -I/usr/include/bsd
Macintosh
We are boycotting Apple because of Apple's efforts to take away
our freedom to write compatible imitations of existing software.
If you value your freedom to write such programs, we urge you
not to buy from Apple, not to develop software for Apple, and
certainly not to accept a job with Apple.
See the file APPLE in this directory for more information.
Masscomp (m-masscomp.h; s-rtu.h)
18.36 worked on a 5500DP running RTU v3.1a and compiler version 3.2
with minor fixes that are included in 18.37. However, bizarre behavior
was reported for 18.36 on a Masscomp (model and version unknown but probably
a 68020 system). The report sounds like a compiler bug.
A compiler bug affecting statements like
unsigned char k; unsigned char *p;... x = p[k];
has been reported for "C version 1.2 under RTU 3.1". We do not wish
to take the time to install the numerous workarounds required to
compensate for this bug; go complain to Masscomp.
For RTU version 3.1, define FIRST_PTY_LETTER to be 'p' in s-rtu.h
(or #undef and redefine it in config.h) so that ptys will be used.
GNU Emacs is said to have no chance of compiling on RTU versions
prior to v3.0.
Megatest (m-mega68.h; s-bsd4-2.h)
Emacs 15 worked; do not have any reports about Emacs 16 or 17
but any new bugs are probably not difficult.
Mips (m-mips.h or m-mips4.h; s-usg5-2-2.h)
Changes merged in 18.39.
Use m-mips4.h for RISCOS version 4.
Motorola Delta (m-delta.h; s-usg5-3.h)
m- file added in version 18.56.
National Semiconductor 32000 (m-ns32000.h; s-usg5-2.h)
This is for a complete machine from National Semiconductor,
running Genix. Changes merged in version 19.
NCR Tower 32 (m-tower32.h; s-usg5-2.h)
Works as of 17.56.
Nixdorf Targon 31 (m-targon31.h; s-usg5-2-2.h)
m- file for version 17 is included in 18
but whether it works is not known.
src/unexec.c bombs if compiled with -O.
Note that the "Targon 35" is really a Pyramid.
Nu (TI or LMI) (m-nu.h; s-usg5-2.h)
Version 18 is believed to work.
Plexus (m-plexus.h; s-usg5-2.h)
Works as of 17.56.
Pmax (DEC Mips) (m-pmax.h; s-bsd4-2.h)
See under DECstation, above.
Prime EXL (m-intel386.h; s-usg5-3.h)
Minor changes merged in 19.1.
Pyramid (m-pyramid.h; s-bsd4-2.h)
In OSx 4.0, it seems necessary to add the following two lines
to m-pyramid.h:
#define _longjmp longjmp
#define _setjmp setjmp
In Pyramid system 2.5 there has been a compiler bug making
Emacs crash just after screen-splitting with Qnil containing 0.
A compiler that fixes this is Pyramid customer number 8494,
internal number 1923.
Some versions of the pyramid compiler get fatal
errors when the -gx compiler switch is used; if this
happens to you, change src/m-pyramid.h to define
C_DEBUG_SWITCH with an empty definition.
Some old system versions may require you to define PYRAMID_OLD
in when alloca.s is preprocessed, in order to define _longjmp and _setjmp.
Sequent Balance (m-sequent.h; s-bsd4-2.h, or s-bsd4-3.h on newer systems)
Emacs 18.51 should work on system version 3.0. 18.52 is said to work.
Delete some lines at the end of m-sequent.h for earlier system versions.
Sequent Symmetry (m-symmetry.h; s-bsd4-3.h)
Emacs 19 should work.
SONY News (m-news.h; s-bsd4-2.h, or s-bsd4-3.h for system release 3)
18.52 should work.
SONY News 3000 series (RISC NEWS) (m-news-risc.h; s-bsd4-3.h)
Works, as of 18.56. Note that this is a MIPS architecture machine.
Stardent 1500 or 3000
See Titan.
Stride (m-stride.h; s-usg5-2.h)
Works (most recent news for 18.30) on their release 2.0.
For release 2.2, see the end of m-stride.h.
It may be possible to run on their V.1 system but changes
in the s- file would be needed.
Sun 1, 2 and 3 (m-sun1.h, m-sun2.h, m-sun3.h; s-bsd4-2.h or s-sunos4.h)
There are three m- files for different versions of SunOS.
All are derived from Berkeley 4.2. Emacs 17 has run on all of them.
Whether you should use m-sun1.h, m-sun2.h or m-sun3.h depends
on the VERSION OF THE OPERATING SYSTEM you have.
You will need to use m-sun3.h on Sun 2's running SunOS release 3.
For SunOS release 4 on a Sun 3, use m-sun3.h and s-sunos4.h.
See the file etc/SUNBUG for how to solve problems caused by bugs in
the "export" version of SunOS 4.
If you have trouble using open-network-stream, get the
distribution of `bind' (the BSD name-server), build libresolv.a,
and link Emacs with -lresolv. This problem is due to obsolete
software in the nonshared standard library.
If you want to use SunWindows, define HAVE_SUN_WINDOWS
in config.h to enable a special interface called `emacstool'.
The definition must *precede* the #include "m-sun3.h".
System version 3.2 is required for this facility to work.
We recommend that you instead use the X window system, which
has technical advantages, is an industry standard, and is also
free software.
If you are compiling for X windows, and the X window library was
compiled to use the 68881, then you must edit config.h according
the comments at the end of m-sun3.h.
Note that Emacs on a Sun is not really as big as it looks.
As dumped, it includes around 200k of zeros between the
original text section and the original data section
(now remapped as part of the text). These are never
swapped in.
To build a single Emacs that will run on Sun 2 and Sun 3
HARDWARE, just build it on the Sun 2.
Sun 4 (m-sparc.h; s-bsd4-2.h or s-sunos4.h)
Changes merged in 18.50. Some people say optimizing compilation
does not work; some say that -O2 (whatever that is) works
perhaps with a small change.
Use s-sunos4.h for operating system version 4.
See the file etc/SUNBUG for how to solve problems caused by bugs in
the "export" version of SunOS 4.
Sun Roadrunner (m-sun386.h; s-sunos4.h)
Changes merged in 18.51.
Tahoe (m-tahoe.h; s-bsd4-2.h or s-bsd4-3.h)
18.52 known to work on some Tahoes, but a compiler bug intervenes
on others. Some Emacs versions have worked in Unisys 1r4
(not in 1r3) and CCI I.21.
If you have trouble compiling etc/loadst.c, turn off the definition
of DKSTAT_HEADER_FILE in m-tahoe.h.
Tektronix 16000 box (6130?) (m-ns16000.h; s-bsd4-2.h)
Emacs 17.61 worked.
Tektronix 4300 (m-tex4300.h; s-bsd4-3.h)
Emacs 18.51 should work.
Titan P2 or P3 (m-titan.h; s-usg5-3.h)
Changes probably merged in version 19.
Ustation E30 (SS5E) (m-ustation.h; s-unipl5-2.h).
Changes merged in 18.52; don't know whether they work.
Vax running Berkeley Unix (m-vax.h; s-bsd4-1.h, s-bsd4-2.h or s-bsd4-3.h)
Works.
Vax running Ultrix (m-vax.h; s-bsd4-2.h)
Works. See under Ultrix for problems using X windows on Ultrix.
Vax running System V rel 2 (m-vax.h; s-usg5-2.h)
18.27 Works.
Vax running System V rel 0 (m-vax.h; s-usg5-0.h)
