-** 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.
-
-** SuperH (sh[34]*-*-linux-gnu)
-
- Emacs 23.0.60 was reported to work on GNU/Linux (October 2008).
- Tested on a little-endian sh4 system (cpu type SH7751R) running
- Gentoo Linux 2008.0.
