Some obsolete platforms are unsupported beginning with Emacs 23.1. See

** 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".
** Apple Macintosh running Mac OS X
** Apple PowerPC Macintosh running GNU/Linux
** HP 9000 series 700 or 800 (Spectrum) (hppa1.0-hp-hpux or hppa1.1-hp-hpux)
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.
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 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. There are reports that IBM compiler versions
earlier than 1.03.00.02 fail even without -O.
As of 19.11, if you strip the Emacs executable, it ceases 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.
** Intel 386 (i386-*-freebsd, i386-*-linux-gnu,
i386-*-cygwin, i386-*-msdos, i386-*-windowsnt.
i386 can be replaced with i486, i586, or i686)
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).
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.)
On GNU/Linux systems, Emacs 19.23 was said to work properly with libc
version 4.5.21, but not with 4.5.19.
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.
On 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.
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.
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 4D (mips-sgi-irix6.*)
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)).
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.
** 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.
There are reports that using SunSoft cc with -xO4 -xdepend produces
bad code for some part of Emacs.
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.
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, 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 editing LIBRESOLV in src/Makefile. 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.

*** 64-bit GNU/Linux
No special procedures should be needed to build a 64-bit Emacs on a
64-bit GNU/Linux system. To build a 32-bit Emacs, first ensure that
the necessary 32-bit system libraries and include files are
installed. Then use:
./configure CC='gcc -m32' --build=i386-linux-gnu \
