This is a list of the status of GNU Emacs on various machines and systems.
For each system and machine, we give the configuration name you should
pass to the `configure' script to prepare to build Emacs for that
system/machine.
The `configure' script uses the configuration name to decide which
machine and operating system description files `src/config.h' should
include. The machine description files are all in `src/m', and have
names similar to, but not identical to, the machine names used in
configuration names. The operating system files are all in `src/s',
and are named similarly. See the `configure' script if you need to
know which configuration names use which machine and operating system
description files.
If you add support for a new configuration, add a section to this
file, and then edit the `configure' script to tell it which
configuration name(s) should select your new machine description and
system description files.
Some obsolete platforms are unsupported beginning with Emacs 23.1, see
the full list at the end of this file.
Here are the configurations Emacs is intended to work with, with the
corresponding configuration names. You can postpend version numbers
to operating system names (i.e. sunos4.1) or architecture names (i.e.
hppa1.1). If you leave out the version number, the `configure' script
will configure Emacs for the latest version it knows about.
Alpha (DEC) running GNU/Linux (alpha-dec-linux-gnu)
DEC C compiler version 5.9 (DEC C V5.9-005 on Digital UNIX V4.0f)
is reported to produce bogus binaries of Emacs 21.2 when the
command-line switches "-O4 -arch ev6 -tune ev6" are used. Using
just -O4 produces a good executable.
For 4.0 revision 564, and 4.0A and 4.0B, Emacs 20 seems to work
with no special configuration options. However, if you use GCC as
your compiler, you will need version 2.8.1 or later, as older
versions fail to build with a message "Invalid dimension for the
charset-ID 160".
Note that the X11 libraries on GNU/Linux systems for the Alpha are
said to have bugs that prevent Emacs from working with X (as of
November 1995). Recent releases work (July 2000).
Apple Macintosh running Mac OS X
For installation on all versions of the Mac OS platform, see the file
mac/INSTALL.
Apple PowerPC Macintosh running GNU/Linux
There are special considerations for a variety of this system which
is known as the ``Yellow Dog [GNU/]Linux'': Emacs may crash during
dumping. To solve this, edit the header file src/m/macppc.h in the
Emacs distribution, and remove the "#if 0" and "#endif" directives
which surround the following block near the end of the file:
#if 0 /* This breaks things on PPC GNU/Linux except for Yellowdog,
even with identical GCC, as, ld. Let's take it out until we
know what's really going on here. */
/* GCC 2.95 and newer on GNU/Linux PPC changed the load address to
0x10000000. */
#if defined __linux__
#if __GNUC__ > 2 || (__GNUC__ == 2 && __GNUC_MINOR__ >= 95)
#define DATA_SEG_BITS 0x10000000
#endif
#endif
#endif /* 0 */
After that, reconfigure and rebuild Emacs. It should now build
successfully.
Cubix QBx/386 (i386-cubix-sysv)
Changes merged in 19.1. Systems before 2/A/0 may fail to compile etags.c
due to a compiler bug.
DECstation (mips-dec-ultrix or mips-dec-osf)
This machine is the older Mips-based DECstation.
Emacs should now work on the Alpha CPU.
19.25 works on Ultrix 4.2. The 19.26 pretest was reported to work
on Ultrix 4.2a and on 4.4.
One user reported 19.25 did not work at all with --with-x-toolkit
using X11R5 patch level 10, but worked ok with X11R5 pl26.
See under Ultrix for problems using X windows on Ultrix.
Note that this is a MIPS machine.
For Ultrix versions 4.1 or earlier, you may need to define
SYSTEM_MALLOC in `src/m/pmax.h', because XvmsAlloc.o in libX11.a seems
to insist on defining malloc itself.
For Ultrix versions prior to 4.0, you may need to delete
the definition of START_FILES from `src/m/pmax.h'.
Motorola Delta 147 (m68k-motorola-sysv)
The EMacs 19.26 pretest was reported to work.
Motorola Delta boxes running System V/68 release 3.
Tested on 147 board with SVR3V7, no X and gcc.
Tested on 167 board with SVR3V7, no X, cc, gnucc and gcc.
Reports say it works with X too.
The installation script chooses the compiler itself. gnucc is
preferred.
Fujitsu DS/90 (sparc-fujitsu-sysv4)
Changes merged in 20.3.
GEC 63 (local-gec63-usg5.2)
Changes are partially merged in version 18, but certainly require
more work. Let us know if you get this working, and we'll give it a
real configuration name.
Harris Power PC (powerpc-harris-powerunix)
Patches have been merged in 19.31.
Hewlett-Packard 9000 series 200 or 300 (m68k-hp-bsd or m68k-hp-hpux
or m68k-hp-netbsd)
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 operating system suffix determines which system Emacs is built for.
Series 200 HPUX runs Emacs only if it has the "HP/UX upgrade".
Version 19 works under BSD. The 19.26 pretest was reported
to work on HPUX 9. 19.31 works on HPUX 10.01, but there are
some problems on 10.10 which have not been resolved. Emacs 19.34
works on HPUX 10.20 provided you compile with GCC; with the HP C
compiler, subprocess commands do not work.
On HPUX 9, Emacs sometimes crashes with SIGBUS or SIGSEGV after you
delete a frame. We think this is due to a bug in the X libraries
provided by HP. With the alternative X libraries in
/usr/contrib/mitX11R5/lib, the problem does not happen.
If you are running HP/UX release 8.0 or later, you need the optional
"C/ANSI C" software in order to build Emacs (older releases of HP/UX
do not require any special software). If the file "/etc/filesets/C"
exists on your machine, you have this software, otherwise you do not.
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 referred to as
Network Services (NS/9000) in HP literature.
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 700 or 800 (Spectrum) (hppa1.0-hp-hpux or hppa1.1-hp-hpux
or ...hpux9shr, or ...-nextstep)
Use hppa1.1 for the 700 series and hppa1.0 for the 800
series machines. (Emacs may not actually care which one you use.)
Support for NextSTEP was added in 19.31.
Emacs 20 may work on HPUX 10. You need patch PHSS_6202 to install
the Xaw and Xmu libraries. On HPUX 10.20 you may need to compile with GCC;
when Emacs was compiled with HP's C compiler, HP92453-01 A.10.32.03,
the subprocess features failed to work.
19.26 is believed to work on HPUX 9 provided you compile with GCC.
As of version 19.16, Emacs was reported to build (using GCC) and run
on HP 9000/700 series machines running HP/UX versions 8.07 and 9.01.
The HP compiler is known to fail on some versions if you use +O3,
but it may work with lower optimization levels.
Use hppa1.1-hp-hpux9shr to use shared libraries on HPUX version 9.
You may need to create the X libraries libXaw.a and libXmu.a from
the MIT X distribute, and you may need to edit src/Makefile's
definition of LIBXT to look like this:
LIBXT= $(LIBW) -lXmu -lXt $(LIBXTR6) -lXext
Some people report trouble using the GNU memory allocator under
HP/UX version 9. The problems often manifest as lots of ^@'s in the
buffer.
We are told that these problems go away if you obtain the latest
patches for the HP/UX C compiler. James J Dempsey
<jjd@spserv.bbn.com> says that this set of versions works for him:
/bin/cc:
HP92453-01 A.09.28 HP C Compiler
/lib/ccom:
HP92453-01 A.09.28 HP C Compiler
HP-UX SLLIC/OPTIMIZER HP-UX.09.00.23 02/18/93
Ucode Code Generator - HP-UX.09.00.23.5 (patch) 2/18/93
For 700 series machines, the HP-UX patch needed is known as
PHSS_2653. (Perhaps for 800 series machines as well; we don't
know.) If you are on the Internet, you should be able to obtain
this patch by using telnet to access the machine
support.mayfield.hp.com and logging in as "hpslreg" and following
the instructions there. Or you may be able to use this
web site:
HP Patch Server: http://support.mayfield.hp.com/patches/html/patches.html
HP Support Line: http://support.mayfield.hp.com
Please do not ask FSF for further support on this. If you have any
trouble obtaining the patch, contact HP Software Support.
If your buffer fills up with nulls (^@) at some point, it could well
be that problem. That problem does not happen when people use GCC
to compile Emacs. On the other hand, the HP compiler version 9.34
was reported to work for the 19.26 pretest. 9.65 was also reported to work.
If you turn on the DSUSP character (delayed suspend),
Emacs 19.26 does not know how to turn it off on HPUX.
You need to turn it off manually.
If you are running HP/UX release 8.0 or later, you need the optional
"C/ANSI C" software in order to build Emacs (older releases of HP/UX
do not require any special software). If the file "/etc/filesets/C"
exists on your machine, you have this software, otherwise you do not.
IBM PS/2 (i386-ibm-aix1.1 or i386-ibm-aix1.2)
Changes merged in version 19. You may need to copy
/usr/lib/samples/hft/hftctl.c to the Emacs src directory.
i386-ibm-aix1.1 may not work with certain new X window managers, and
may be suboptimal.
IBM RS/6000 (rs6000-ibm-aix*)
Emacs 19.26 is believed to work; its pretest was tested.
Compiling with the system's `cc' and CFLAGS containing `-O5' might
fail because libXbsd isn't found. This is a compiler bug;
re-configure Emacs so that it isn't compiled with `-O5'.
On AIX 4.3.x and 4.4, compiling with /bin/c89 fails because it
treats certain warnings as errors. Use `cc' instead.
At last report, Emacs didn't run well on terminals. Informed
persons say that the tty VMIN and VTIME settings have been
corrupted; if you have a fix, please send it to us.
Compiling with -O using the IBM compiler has been known
to make Emacs work incorrectly. It's reported that on
AIX 3.2.5 with an IBM compiler earlier than 1.03.00.14,
cc -O fails for some files. You need to install any
PTF containing APAR #IX42810 to bring the compiler to
the 1.03.00.14 level to allow optimized compiles.
There are reports that IBM compiler versions earlier than 1.03.00.02
fail even without -O. However, another report said that compiler
version 1.02.01.00 did work, on AIX 3.2.4, with Emacs 19.31.
As of 19.11, if you strip the Emacs executable, it ceases to work.
If you are using AIX 3.2.3, you may get a core dump when loading
ange-ftp. You may be able to fix the problem by defining LIBS_TERMCAP
as -ltermcap -lcurses. Please tell us if this fails to work.
If anyone can fix the above problems, or confirm that they don't happen
with certain versions of various programs, we would appreciate it.
IBM System/390 running GNU/Linux (s390-*-linux-gnu)
As of Emacs 21.2, a 31-bit only version is supported on this
system.
Integrated Solutions `Optimum V' (m68k-isi-bsd4.2 or -bsd4.3)
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 `lib-src/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 386 (i386-*-bsdi2, i386-*-freebsd, i386-*-linux-gnu,
i386-*-sol2.4, i386-*-sysv3, i386-intsys-sysv,
i386-*-sysv4, i386-*-sysv4.2,
i386-*-sysv5.3, i386-*-bsd4.2, i386-*-cygwin,
i386-*-bsd386, i386-*-386bsd,
i386-*-msdos, i386-*-windowsnt.
i386... can be replaced with i486... or i586...)
In the above configurations, * means that the manufacturer's name
you specify does not matter, and you can use any name you like
(but it should not contain any dashes or stars).
When using the ISC configurations, be sure to specify the isc
version number - for example, if you're running ISC 3.0, use
i386-unknown-isc3.0 as your configuration name.
Use i386-*-linux-gnu for GNU/Linux systems; Emacs runs as of version 19.26.
Use i386-*-cygwin for Cygwin; Emacs builds as of version 22.1, in both X11
and non-X11 modes. (The Cygwin site has source and binaries for 21.2.)
Use i386-intsys-sysv for Integrated Solutions 386 machines.
It may also be correct for Microport systems.
On GNU/Linux systems, Emacs 19.23 was said to work properly with libc
version 4.5.21, but not with 4.5.19. If your system uses QMAGIC
for the executable format, you must edit config.h to define LINUX_QMAGIC.
On GNU/Linux, configure may fail to put these definitions in config.h:
#define HAVE_GETTIMEOFDAY
#define HAVE_MKDIR
#define HAVE_RMDIR
#define HAVE_XSCREENNUMBEROFSCREEN
To work around the problem, add those definitions by hand.
It is possible that this problem happens only with X11R6.
Newer system versions have fixed it.
The 19.26 pretest was reported to work on SVR4.3 and on Freebsd.
19.29 is reported to crash when using Motif on Solaris 2.5.
The reasons are not yet known.
Use i386-*-bsdiN for BSDI BSD/OS version N; Emacs runs as of version 19.23.
In some system versions, `make' is broken; use GNU make instead.
Shell bugs in version 1.0 of BSD/OS cause configure
to do the wrong thing with --with-x-toolkit; the workaround is to edit
configure to run another shell such as bash.
For System V release 3, use i386-*-sysv3.
For System V release 4, use i386-*-sysv4.
For System V release 4.2, use i386-*-sysv4.2.
If you are using SCO Unix, see notes at end under SCO.
On 386bsd, NetBSD and FreeBSD, at one time, it was necessary to use
GNU make, not the system's make. Assuming it's installed as gmake,
do `gmake install MAKE=gmake'. However, more recently it is
reported that using the system Make on NetBSD 1.3.1 works ok.
If you are using System V release 4.2, you may find that `cc -E'
puts spurious spaces in `src/xmakefile'. If that happens,
specify CPP=/lib/cpp as an option when you run make.
There is no problem if you compile with GCC.
Note that use of Linux with GCC 2.4 and the DLL 4.4 libraries
requires the experimental "net 2" network patches (no relation to
Berkeley Net 2). There is a report that (some version of) Linux
requires including `/usr/src/linux/include/linux' in buffer.c
but no coherent explanation of why that might be so. If it is so,
in current versions of Linux, something else should probably be changed.
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.
On 386/ix, to link with shared libraries, add #define USG_SHARED_LIBRARIES
to config.h.
On SCO, there are problems in regexp matching when Emacs is compiled
with the system compiler. The compiler version is "Microsoft C
version 6", SCO 4.2.0h Dev Sys Maintenance Supplement 01/06/93;
Quick C Compiler Version 1.00.46 (Beta). The solution is to compile
with GCC.
On ISC systems (2.02 and more recent), don't try to use the versions
of X that come with the system; use XFree86 instead.
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.
For a given version of the system, this may depend on whether you have
X Windows or TCP/IP. Define or undefine NO_SIOCTL_H in config.h
according to whether you have the file.
Likewise, some versions have been known to need sys/ttold.h, sys/stream.h,
and sys/ptem.h included in sysdep.c. If your system has these files,
try defining NEED_PTEM_H in config.h if you have trouble without it.
You may find that adding -I/usr/X/include or -I/usr/netinclude or both
to CFLAGS avoids compilation errors on certain systems.
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.
Iris 2500 and Iris 2500 Turbo (m68k-sgi-iris3.5 or m68k-sgi-iris3.6)
Version 18 was said to work; use m68k-sgi-iris3.5 for system version 2.5
and m68k-sgi-iris3.6 for system version 3.6.
Note that the 3030 is the same as the Iris 2500 Turbo.
Iris 4D (mips-sgi-irix[456].*)
Emacs 21.3 is reported to work on IRIX 6.5.x.
You can build a 64-bit executable (with larger maximum buffer size)
on Irix 6.5 by specifying the 64-bit ABI using the `-64' compiler
flag or otherwise (see cc(1)). This may work on earlier Irix 6
systems if you edit src/s/irix6-0.h following irix6-5.h.
If compiling with GCC on Irix 6 yields an error "conflicting types
for `initstate'", install GCC 2.95 or a newer version, and this
problem should go away. It is possible that this problem results
from upgrading the operating system without reinstalling GCC; so you
could also try reinstalling the same version of GCC, and telling us
whether that fixes the problem.
Mips (mips-mips-riscos, mips-mips-riscos4.0, or mips-mips-bsd)
The C compiler on Riscos 4.51 dumps core trying to optimize
parts of Emacs. Try without optimization or try GCC.
Meanwhile, the linker on that system returns success even if
there are undefined symbols; as a result, configure gets the
wrong answers to various questions. No work-around is known
except to edit src/config.h by hand to indicate which functions
don't exist.
Use mips-mips-riscos4.0 for RISCOS version 4.
Use mips-mips-bsd with the BSD world.
Note that the proper configuration names for DECstations are
mips-dec-ultrix and mips-dec-osf.
If you are compiling with GCC, then you must run fixincludes;
the alternative of using -traditional won't work because
the definition of SIGN_EXTEND_CHAR uses the keyword `signed'.
If the SYSV world is the default, then you probably need the following
line in etc/Makefile:
CFLAGS= -g -systype bsd43
Some operating systems on MIPS machines give SIGTRAP for division by
zero instead of the usual signals. The only real solution is to fix
the system to give a proper signal.
In the meantime, you can change init_data in data.c if you wish.
Change it to handle SIGTRAP as well as SIGFPE. But this will have a
great disadvantage: you will not be able to run Emacs under a
debugger. I think crashing on division by zero is a lesser problem.
dsg@mitre.org reported needing to use --x-libraries=/bsd43/usr/lib
on a riscos4bsd site. But it is not clear whether this is needed in
general or only because of quirks on a particular site.
NCR Intel system (i386-ncr-sysv4.2)
This system works in 19.31, but if you don't link it with GNU ld,
you may need to set LD_RUN_PATH at link time to specify where
to find the X libraries.
NEC EWS4800 (mips-nec-sysv4)
This system works in 20.4, but you should use the compiler
/usr/abiccs/bin/cc (MIPS ABI MODE).
NeXT (m68k-next-nextstep)
Emacs 19 has not been tested extensively yet, but it seems to work
in a NeXTStep 3.0 terminal window, and under the X server called
co-Xist. You may need to specify -traditional when src/Makefile
builds xmakefile.
NeXT users might want to implement direct operation with NeXTStep,
but from the point of view of the GNU project, that is a
distraction.
Thanks to Thorsten Ohl for working on the NeXT port of Emacs 19.
Pmax (DEC Mips) (mips-dec-ultrix or mips-dec-osf1)
See under DECstation, above.
Prime EXL (i386-prime-sysv)
Minor changes merged in 19.1.
Sequent Symmetry (i386-sequent-bsd, i386-sequent-ptx, i386-sequent-ptx4)
19.33 has changes to support ptx 4 (a modified SVR4).
Emacs 19 should work on Dynix (BSD). However, if you compile with
the Sequent compiler, you may find Emacs does not restore the
terminal settings on exit. If this happens, compile with GCC.
Emacs 19.27 contains patches that should support
DYNIX/ptx 1.4 and 2.1 with the native cc compiler.
GCC can't compile src/process.c due to a non-standard Sequent asm
keyword extension supported by cc and used for the network byte/word
swapping functions in the PTX /usr/include/netinet/in.h file. GCC
2.5.8 includes the file <sys/byteorder.h> which can be included into
netinet/in.h to perform these byte/word swapping functions in the
same manner. Patches have been submitted to the FSF against GCC
2.6.0 to fix this problem and allow Emacs to be built with GCC.
If your machine does not have TCP/IP installed, you will have to edit the
src/s/ptx.h file and comment out #define TCPIP_INSTALLED.
Siemens Nixdorf RM600 and RM400 (mips-siemens-sysv4)
Changes merged in 19.29. The version configured with
`--with-x' works without any modifications, but `--with-x-toolkit'
works only if the Athena library and the Toolkit library are linked
statically. For this, edit `src/Makefile' after the `configure' run
and modify the lines with `-lXaw' and `-lXt' as follows:
LIBW= /usr/lib/libXaw.a
LIBXT= $(LIBW) -lXmu /usr/lib/libXt.a $(LIBXTR6) -lXext
In addition, `--with-x-toolkit=motif' works only
if the Motif library and the Toolkit library are linked statically.
To do this, edit `src/Makefile' after the `configure' run
and modify the lines with `-lXm' and `-lXt' as follows:
LIBW= /usr/lib/libXm.a /usr/ccs/lib/libgen.a
LIBXT= $(LIBW) -lXmu /usr/lib/libXt.a $(LIBXTR6) -lXext
SONY News (m68k-sony-bsd4.2 or m68k-sony-bsd4.3)
18.52 worked. Use m68k-sony-bsd4.3 for system release 3.
SONY News 3000 series (RISC NEWS) (mips-sony-bsd)
The 19.26 pretest is reported to work.
Some versions of the operating system give SIGTRAP for division by zero
instead of the usual signals. This causes division by zero
to make Emacs crash. The system should be fixed to give the proper signal.
Changing Emacs is not a proper solution, because it would prevent
Emacs from working under any debugger. But you can change init_data
in data.c if you wish.
Sun 3, Sun 4 (sparc), Sun 386 (sparc-sun-solaris2.*,
i386-sun-solaris2.*, sparc*-*-linux-gnu)
To build a 32-bit Emacs (i.e. if you are having any sort of problem
bootstrapping a 64-bit version), you can use the Sun Studio compiler
and configure Emacs with:
env CC="cc -xarch=v7" CFLAGS='' ./configure # on SPARC systems
env CC="cc -xarch=386" CFLAGS='' ./configure # on x86 systems
On Solaris 2.10, it is also possible to use /usr/sfw/bin/gcc to build
a 32-bit version of Emacs. Just make sure you point ./configure to
the right compiler:
env CC='/usr/sfw/bin/gcc -m32' ./configure
To build a 64-bit Emacs (with larger maximum buffer size and
including large file support) on a Solaris system which supports
64-bit executables, use the Sun compiler, configuring something like
this (see the cc documentation for information on 64-bit
compilation):
env CC="cc -xarch=v9" CFLAGS='' ./configure # on SPARC systems
env CC="cc -xarch=amd64" CFLAGS='' ./configure # on x86 systems
As of version 2.95, GCC doesn't support the 64-bit ABI properly, but
later releases may.
Some versions of Solaris 8 have a bug in their XIM (X Input Method)
implementation which causes Emacs to dump core when one of several
frames is closed. To avoid this, either install patch 108773-12
(for Sparc) or 108874-12 (for x86), or configure Emacs with the
`--with-xim=no' switch (you can use Leim input methods instead).
On Solaris 2.7, building Emacs with WorkShop Compilers 5.0 98/12/15
C 5.0 failed, apparently with non-default CFLAGS, most probably due to
compiler bugs. Using Sun Solaris 2.7 Sun WorkShop 6 update 1 C
release was reported to work without problems. It worked OK on
another system with Solaris 8 using apparently the same 5.0 compiler
and the default CFLAGS.
Emacs 21.1 and 21.2 built with Sun's ProWorks PC3.0.1 compiler on
Intel/Solaris 8 was reported to abort and dump core during startup.
Using GCC or a newer SUN compiler (Sun WokShop 6 update 2 C 5.3
2001/05/15) solves the problem.
Emacs 20.5 and later work on SPARC GNU/Linux with the 32-bit ABI.
As of release 2.95, GCC doesn't work properly with the 64-bit ABI
(applicable on UltraSPARC), but that isn't the default mode.
Emacs 20.3 fails to build on Solaris 2.5 if you use GCC 2.7.2.3.
Installing GCC 2.8 fixes the problem.
19.32 works on Solaris 2.4 and 2.5. On Solaris 2.5
you may need one of these patches to prevent Emacs from crashing
when it starts up:
103093-03: [README] SunOS 5.5: kernel patch (2140557 bytes)
102832-01: [README] OpenWindows 3.5: Xview Jumbo Patch (4181613 bytes)
103242-04: [README] SunOS 5.5: linker patch (595363 bytes)
There are reports that using SunSoft cc with -xO4 -xdepend produces
bad code for some part of Emacs.
Emacs works ok Sunos 4.1.x
provided you completely replace your C shared library
using one of the SunOS 4.1.x jumbo replacement patches from Sun.
Here are the patch numbers for Sunos 4.1.3:
100890-10 SunOS 4.1.3: domestic libc jumbo patch
100891-10 SunOS 4.1.3: international libc jumbo patch
Some people report that Emacs crashes immediately on startup when
used with a non-X terminal, but we think this is due to compiling
with GCC and failing to use GCC's "fixed" system header files.
Some Sun versions of X windows use the clipboard, not the selections,
for transferring text between clients. The Cut, Paste and Copy items
in the menu bar Edit menu work with the clipboard.
A user reported irreproducible segmentation faults when using 19.29
on Solaris 2.3 and 2.4 after compiling it with the Sun compiler.
The problem went away when GCC 2.7.0 was used instead. We do not know
whether anything in Emacs is partly to blame for this.
X11R6 is set up to make shared libraries only, on Sunos 4.
Therefore, in order to link Emacs, you need to create static X libraries.
To do this, rebuild X11 after setting
#define ForceNormalLib YES
#define SeparateSharedCompile YES
in site.def (after #ifdef AfterVendorCF).
If you compile with Sun's ANSI compiler acc, you need additional options
when linking temacs, such as
/usr/lang/SC2.0.1/values-Xt.o -L/usr/lang/SC2.0.1/cg87 -L/usr/lang/SC2.0.1
(those should be added just before the libraries) and you need to
add -lansi just before -lc. The precise file names depend on the
compiler version, so we cannot easily arrange to supply them.
On Solaris 2, you need to install patch 100947-02 to fix a system bug.
Presumably this patch comes from Sun. You must alter the definition of
LD_SWITCH_SYSTEM if your X11 libraries are not in /usr/openwin/lib.
You must make sure that /usr/ucblib is not in your LD_LIBRARY_PATH.
On Solaris 2.2, with a multiprocessor SparcCenter 1000, Emacs 19.17 is
reported to hang sometimes if it exits while it has one or more
subprocesses (e.g. the `wakeup' subprocess used by `display-time').
Emacs and its subprocesses become zombies, and in their zombie state
slow down their host and disable rlogin and telnet. This is most
likely due to a bug in Solaris 2.2's multiprocessor support,
rather than an Emacs bug.
On Solaris, do not use /usr/ucb/cc. Use /opt/SUNWspro/bin/cc. Make
sure that /usr/ccs/bin and /opt/SUNWspro/bin are in your PATH before
/usr/ucb. (Most free software packages have the same requirement on
Solaris.) With this compiler, use `/opt/SUNWspro/bin/cc -E' as the
preprocessor. If this inserts extra whitespace into its output (see
the PROBLEMS file) then add the option `-Xs'.
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, by copying the #definition of LIBS_SYSTEM in
src/s/sunos4-1.h to src/config.h. This problem is due to obsolete
software in the nonshared standard library.
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.
On Sunos 4.1.3, the word is that Emacs can loop infinitely
on startup with X due perhaps to a bug in Sunos. Installing all of
these Sun patches fixes the problem. We don't know which of them
are really relevant.

Tadpole 68K (m68k-tadpole-sysv)
Changes merged in 19.1.
You may need to edit Makefile to change the variables LIBDIR and
BINDIR from /usr/local to /usr/contrib.
To give movemail access to /usr/mail, you may need to execute
chmod 2755 etc/movemail; chgrp mail etc/movemail
Tandem Integrity S2 (mips-tandem-sysv)
Changes merged in 18.56 but subprocess support is turned off.
You will probably want to see if you can make subprocesses work.
You must edit `lib-src/Makefile' to define LOADLIBES = -mld.
Vaxen running Berkeley Unix (vax-dec-bsd4.1, vax-dec-bsd4.2, vax-dec-bsd4.3),
Ultrix (vax-dec-ultrix),
System V (vax-dec-sysv0, vax-dec-sysv2), or
VMS (vax-dec-vms)
Works.
See under Ultrix for problems using X windows on Ultrix (vax-dec-ultrix).
18.27 worked on System V rel 2 (vax-dec-sysv2).
18.36 worked on System V rel 0 (vax-dec-sysv0).
Richard Levitte <levitte@e.kth.se> distributes a set of patches to
Emacs 18.59 to make it work nicely under VMS. Emacs 19 probably
won't work very well, or even compile. Levitte is working on a
port, so these problems should be fixed in the near future.
Here are notes about some of the systems supported:
Berkeley 4.1 (bsd4.1)
Works on vaxes.
Berkeley 4.2 (bsd4.2)
Works on several machines.
Berkeley 4.3 (bsd4.3)
Works, on Vaxes at least.
Linux (actually GNU/Linux)
Most of the complete systems which use the Linux kernel are close
enough to the GNU system to be considered variant GNU systems. We
call them "Linux-based GNU systems," or GNU/Linux for short.
It is not coincidence that many of the other components used with
Linux--including GNU Emacs--were developed specifically for the GNU
project. The GNU project was launched in 1984 to develop a free
complete Unix-like operating system. To reach this goal, we had to
develop whatever system components were not available as freely
redistributable software from some other source.
The GNU project wants users of GNU/Linux systems to be aware of how
these systems relate to the GNU project, because that will help
spread the GNU idea that software should be free--and thus encourage
people to write more free software. See the file LINUX-GNU in this
directory for more explanation.
Microport
See under "Intel 386".
MSDOS
For installation on MSDOS, see the file INSTALL (search for `MSDOG',
near the end of the file). See the "MS-DOS" chapter of the manual
for information about using Emacs on MSDOS.
SCO Unix
If you are using MMDF instead of sendmail, you need to remove
/usr/lib/sendmail or modify lisp/paths.el before compiling.
lisp/paths.el (which is loaded during the build) will attempt to use
sendmail if it exists.
If you are using SMAIL, you need to define the macro
SMAIL in config.h.
System V rel 0 (usg5.0)
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 (usg5.2)
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 `src/m/MACHINENAME.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 (usg5.2.2)
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 (usg5.3)
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.
You may have to add ANSI idempotence #-lines to your sys/types.h
file to get Emacs to compile correctly. This may be necessary on
other pre-ANSI systems as well.
On an AT&T 6386WGS using System V Release 3.2 and X11R3, the X support
cannot be made to work. Whether or not the GNU relocating malloc is
used, the symptom is that the first call Emacs makes to sbrk(0) returns
(char *)-1. Sorry, you're stuck with character-only mode. Try
installing XFree86 to fix this.
System V rel 4.0.3 and 4.0.4 (usg5.4)
Supported, including shared libraries for ELF, but ptys do not work
because TIOCGPGRP fails to work on ptys (but Dell 2.2 seems to have
fixed this). 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. This is untrue;
ptys are an extension, and POSIX says that extensions *when used*
may change the action of standard facilities in any fashion.
If you get compilation errors about wrong number of
arguments to getpgrp, define GETPGRP_NO_ARG.
The standard C preprocessor may generate xmakefile incorrectly. However,
/lib/cpp will work, so use `make CPP=/lib/cpp'. Standard cpp
seems to work OK under Dell 2.2.
Some versions 3 and earlier of V.4, on the Intel 386 and 860, had
problems in the X11 libraries. These prevent Emacs from working
with X. You can use Emacs with X provided your copy of X is based
on X11 release 4 or newer, or is Dell's 2.2 (which is a 4.0.3).
Unfortunately, the only way you can tell whether your X11 library is
new enough is to try compiling Emacs to use X. If emacs runs, your
X11 library is new enough.
In this context, GSV4 and GSV4i are alternate names for X11R4.
OL2.* is X11R3 based. OL3 is in between X11R3 and X11R4, and may or
may not work, depending on who made the Unix system. If the library
libXol is part of the X distribution, then you have X11R3 and Emacs
won't work with X.
Most versions of V.4 support sockets. If `/usr/lib/libsocket.so'
exists, your system supports them. If yours does not, you must add
#undef HAVE_SOCKETS in config.h, after the inclusion of s-usg5-4.h.
(Any system that supports Internet should implement sockets.)
Ultrix (bsd4.3)
Recent versions of Ultrix appear to support the features of Berkeley 4.3.
Ultrix was at the BSD 4.2 level for a long time after BSD 4.3 came out.
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.
VMS (vmsM.N)
Richard Levitte <levitte@e.kth.se> distributes a set of patches to
Emacs 18.59 to make it work nicely under VMS. Emacs 19 probably
won't work very well, or even compile. Levitte is working on a
port, so these problems should be fixed in the near future.
Note that Emacs for VMS is usually distributed in a special VMS
distribution. See the file ../vms/VMSINSTALL for info on moving
Unix distributions to VMS, and other VMS-related topics.
Windows NT/95/98/ME/2000
For installation on all versions of the MS-Windows platform, see the
file nt/INSTALL.
X86_64 GNU/Linux
No special procedures should be needed to build a 64-bit Emacs. To
build a 32-bit Emacs, first ensure that the necessary 32-bit system
libraries and include files are installed. Then use:
env CC="gcc -m32" ./configure --build=i386-linux-gnu \
--x-libraries=/usr/X11R6/lib
(using the location of the 32-bit X libraries on your system).
