  add -lansi just before -lc.  The precise file names depend on the
  compiler version, so we cannot easily arrange to supply them.

  On SunOS 4.1.1, do not use /usr/5bin/cc.  You can use gcc or/usr/bin/cc.
  Make sure the environment variable LD_LIBRARY_PATH is not defined.

  Some people report crashes on SunOS 4.1.3 if SYSTEM_MALLOC is defined.
  Others have reported that Emacs works if SYSTEM_MALLOC is defined, and not
  if it is undefined.  So far we do not know why results vary in this way.
  The sources are set up so that SYSTEM_MALLOC is defined; if that crashes,
  or if you want the benefit of the relocating memory allocator, you can
  try enabling the #undef SYSTEM_MALLOC in src/s/sunos4-1-3.h.

  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.)

  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.

  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 "machine.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.  The FSF does not support the SunWindows code;
  we installed it only on the understanding we would not let it
  divert our efforts from what we think is important.

  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 `src/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.

  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

Tahoe (tahoe-tahoe-bsd4.2 or tahoe-tahoe-bsd4.3)

  18.52 was 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 `lib-src/loadst.c', turn off the definition
  of DKSTAT_HEADER_FILE in `src/m/tahoe.h'.

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.

Tektronix XD88 (m88k-tektronix-sysv3*)

  The 19.26 pretest was reported to work.
  Minor changes merged in 19.19.

Tektronix 16000 box (6130?) (ns16k-tektronix-bsd)

  Emacs 17.61 worked.

Tektronix 4300 (m68k-tektronix-bsd)

  Emacs 19.26 pretest reported to work.

Titan P2 or P3 (titan-titan-sysv)

  Changes probably merged in version 19.

Ustation E30 (SS5E) (m68k-unisys-unipl)

  Changes merged in 18.52; don't know whether they work.

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 <[e-mail]> 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.

Whitechapel MG1 (ns16k-whitechapel-?)

  May work.  Supposedly no changes were needed except in `src/m/mg1.h'
  file.  I do not know what Unix version runs on them.

Wicat (m68k-wicat-sysv)

  Changes merged as of 18.6; whether they work is unknown.
  See comments in `src/m/wicat.h' for things you should change
  depending on the system and compiler version you have.

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.

Esix

  The following was written for Emacs 18.59 and has been
  slightly adapted for Emacs 19.  It may need more change to be correct.

  Use s/usg5-4.h for Esix System V 4.0.[34] systems if you also have
  XFree86.  If you insist on using the Esix X Window libraries, good
  luck.  s/esix5r4.h provides a starting point, but doesn't seem to
  work consistently.  The basic problems involve the need to load
  -lX11 *last* in the link command, and even then some things break.
  You get best results by installing XFree86 and forgetting about the
  Esix stuff unless you want to run IXI xdt3, which really only needs
  the Esix X11 shared libraries.

  To compile with XFree86, make sure that your LD_LIBRARY_PATH
  contains /usr/X386/lib.  Be careful if you also have the Esix X
  Window libraries that /usr/X386/lib appears *first* in the
  LD_LIBRARY_PATH.  Then define C_SWITCH_X_SYSTEM -I/usr/X386/include.

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 have TCP but not X, you need to edit src/s/sco4.h
  to define HAVE_SOCKETS.

  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.

Uniplus 5.2 (unipl5.2)

  Works, on Dual machines at least.

VMS (vmsM.N)

  Richard Levitte <[e-mail]> 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.

Xenix (xenix)

  Should work in 18.50, but you will need to edit the files
  `lib-src/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.
