ZSH ON SPECIFIC ARCHITECTURES
-----------------------------

These are the OSes that zsh has been tried on.  If you succeed in getting
zsh to work on an OS not listed, let us know.  The information in this
list may be out of date, as the developers do not have access to all
machines.  In general, GNU/Linux distributions, Solaris and Cygwin are
reasonably well covered.  Please let us have any recent information
on other systems.  The information for systems not known to have been
tested recently is marked as `out of date'.

On all machines if you use gcc and upgrade your OS you must rebuild gcc
after the OS upgrade.  A gcc left from a previous OS may seem to work
but compiling more complex programs may fail mysteriously.

The format of entries is thus:

		information

Machines
--------

Apple: MacOS X/Darwin 10.x
	Should build `out-of-the-box'.

	For dynamic loading to work on 10.1 and 10.2, you need to use the
	dlcompat library.  It can be downloaded from:
	    http://sourceforge.net/project/showfiles.php?group_id=17203

	The zsh/zpty library is not working on 10.1 and 10.2, but is on
	10.3.  This causes the tests starting `Y' in the Test directory to
	fail, even though the features to be tested are working.

Red Hat Inc.: Cygwin
	Should build `out-of-the-box'.  The compilation directory should
	be on a file system mounted as binary (the mount command shows
	`binmode'). There are various issues with Cygwin versions before
	1.3.2 - you are adviced to update to the latest release.

	Dynamic loading works as of cygwin-1.1.3 and binutils-20000722-1.
	It was not tested for earlier versions. This does not imply
	that every module will work. New completion and in
	particular zsh/zftp and zsh/mathfunc are known to work.

	Some of the tests in the Test subdirectory are known to fail:
	this is because the UNIX environment is not completely implemented.

	Cygwin allows mount without existing mount point (e.g.
	"mount //server/path /usr/src" where /usr/src does not exist).
	Path completion will fail inside these mounts; make sure that
	every mount point really exists.

DEC: Ultrix (Alpha or DECstation)
DEC: Mach 3.0 (DECstation 5000/25)
DEC: OSF/1 1.2, 1.3, 2.0, 3.x, DEC Unix 4.x (Alpha)
	[Out of date.]

	In OSF/1 3.x, there is apparently a bug in the header file
	/usr/include/rpcsvc/ypclnt.h; the prototype for yp_all() has a
	struct ypall_callback as its final argument, which should be a
	pointer (struct ypall_callback *).  This prevents compilation of
	one of zsh' files (zle_tricky.c).  If you can't modify the header
	file, create a directory called `rpcsvc' in zsh's Src subdirectory
	and put a fixed version of the header file to it before compiling.

	The strip coming with gcc-2.7.2 seems to create unusable binaries.
	This problem is not related to zsh.  If you have such problems,
	remove the bogus strip and use /bin/strip instead.

	On Digital UNIX 4.0, compilation with gcc and with --enable-dynamic
	apparently needs configuring with explicit flags when compiling
	with debugging enabled:
	 DLLD=gcc LDFLAGS='-g -rpath <path-to-.so-files>' ./configure ...

FreeBSD: FreeBSD 2.2.7, 3.x, 4.x
	Should build `out-of-the-box'.  On FreeBSD 2.2, dynamic	loading
	does not work, but it does with 3.x and 4.x.

HP: HP-UX 9, 10.20, 11.x (PA-RISC, Itanium)
	Should build `out-of-the-box'.

	Previous problems encountered on HP-UX 11.x:

	  Some of the special keys on the keyboard (backspace, delete)
	  have been found to stop functioning.  One suggested fix is
	  to alter the way the curses library is linked in the Makefile.
	  Replacing `-lcurses' with `-lHcurses -lcurses' in the libraries
	  is reported to fix.  An attempt to fix this in configure
	  is apparently ineffective; more information would be appreciated
	  as the maintainers do not have access to an HP-UX system.
	  Recent reports indicated this is not necessary on recent versions
	  of HP-UX 11.

	  Compiling with gcc 2.7.1 is known to fail with header file
	  conflicts.  Use the HP ANSI C compiler.

HP/Compaq: Tru64 4.x, 5.x
	  Should build `out-of-the-box'.

IBM: AIX 3.2, 4.x, 5.x
	Should build `out-of-the-box'.

	Certain features will not work, in particular --enable-cap
	and --enable-zsh-mem.  (The feature enabled by --enable-cap
	is apparently present, however.  Help getting this to work
	would be appreciated.)

	On 3.2, for 64-bit integer support you need to compile with gcc, as
	the native compiler does not support ANSI simultaneously with
	`long long'.  On 4.1, there appeared to be problems using
	--enable-dynamic (the default) with gcc (version was 2.7.2.3),
	though native cc works. More information about this problem
	would be appreciated.

	It was reported, that at least some 4.x versions have problem
	with curses - variables boolcodes and some other are declared
	in term.h but missing is libcurses.a. That makes native compiler
	very unhappy (GCC 3.0 apparently does not mind). Zsh now defaults
	to termcap on AIX; any info about this problem is appreciated.

Linux: Linux 2.x (various 32-bit and 64-bit processors)
	Should build `out-of-the-box'.

	If you are using an early minor version of libc 5, then a bug
	in the auto-configuration process may cause zsh to think that
	your system doesn't support the lstat function.  If the configure
	process reports that there is no lstat, edit config.h and change
	HAVE_LSTAT to 1.  libc-5.2.18 or later does not have this problem.

	Various problems have been reported when using optimisation
	with the experimental GNU compiler, egcs.  In particular,
	on Linux Alpha with egcs 1.0.3a and 1.1.1 using -O1 or greater,
	the completion code is not correctly compiled.

	Some versions of glibc2 have a conflict with <asm/resource.h>
	which causes a redefinition warning on RLIM_INFINITY.  This
	causes configure to decide that <sys/resource.h> is not present,
	which can cause compilation errors in zsh's rlimit code.  The
	best solution is to edit config.h after running configure and
	#define HAS_SYS_RESOURCE_H.

NetBSD: NetBSD 1.x
	Should build `out-of-the-box'.

OpenBSD: OpenBSD 2.x, 3.x
	Should build `out-of-the-box'.

SIEMENS: Reliant UNIX
	[Out of date.]

	Builds `out-of-the-box'. Dynamic loading is supported. 
	Large Files and 64-bit integers are supported as of version 5.44
	and CDS/CDS++ compiler.

SIEMENS: SINIX
	[Out of date.]

	MX (Intel) platform: SINIX-L/M 5.41
	Builds out-of-the-box with EGCS. Neither dynamic loading nor
	64-bit integers are supported. Native compiler was not tried
	mostly because GCC/EGCS builds out-of-the-box as well. If you 
	succeed with native compiler, send a patch for this file
	to zsh-workers.

	RM (MIPS) platform: SINIX-N/Y 5.42
	Should build out-of-the-box but it was not tested. Neither
	dynamic loading nor 64-bit integers are supported.
	Note, that this version is obsolete and users are expected to 
	update to Reliant UNIX.

SGI: IRIX 6.2, 6.3, 6.5
	[Out of date.]

	Should build `out-of-the-box'.

	On 6.5.2, zsh malloc routines are reported not to work; also
	full optimization (cc -O3 -OPT:Olimit=0) causes problems.

	If using the SGI compiler, variable length arrays need to
	be turned off.  configure can work this out for itself if it
	is passed the option --enable-cflags='-LANG:vla=off -O' (combined
	with other flags if necessary).

	The zpty module is not currently supported.  This causes the
	tests starting `Y' in the Test directory to fail, even though
	the features to be tested are working.

Sun: SunOS 4.1.x
	[Out of date.]

	Under 4.1.3 if yellow pages is used, username completion may cause
	segmentation violation.  This is a bug in the shared library not
	in zsh.  Some libc.so.1.9.* has this bug (it fails in yp_all).
	Statically linked binaries will work if linked with libc.so.1.8.1
	(which means that if you can get a statically linked binary
	compiled under 4.1.2 that it will probably work).  An alternative
	but untested solution may be to undefine HAVE_NIS in config.h.
	This may work, but the first username completion will be _very_
	slow (as slow as in tcsh).

Sun: Solaris 2.x, 8, 9
	The UCB versions of the routines for reading directories are not
	usable (the struct definitions are incompatible with the ones
	assumed by zsh).  The symptom of this is that globbed filenames in
	the compiled version of zsh will be missing the first two letters.
	To avoid this, make sure you compile zsh without any reference
	to /usr/ucblib in your LD_LIBRARY_PATH.  You can easily do this
	by just unsetting LD_LIBRARY_PATH before building zsh.

	Problems were once reported using --enable-lfs (the default) to
	enable large file system and integer support on Solaris 2 with gcc
	before 2.95.2.  Recent versions of gcc appear to be unproblematic.

Other machines
--------------

Zsh has previously been compiled on the following machines, but the
developers do not have direct access to them and the reports may be out of
date.  We would be glad to receive any reports of success or failure on
these OS's --- and, of course, any others not mentioned in this file.

Apple/NeXT OpenStep 4.2 for i386.
	Reported to work at least with gcc 2.8.1 and gawk 2.15 patchlevel
	6, but not with the bundled cc 2.7.2.1 and awk.

Cray: Unicos (C90 and T90)
	Should build `out-of-the-box'.

Data General: DG/UX 5.4R3.10 MU01 (various AViiONs)
	Should build `out-of-the-box'.

Next: NextStep 3.*
	Should build `out-of-the-box', but the zsh malloc routines are
	not recommended.

SCO: UnixWare 2.1.3
	Builds `out-of-the-box'.
