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.

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:

	Vendor: OS & version (hardware type) [zsh version tried]
		information

Machines
--------

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'.

DEC: Ultrix (Alpha or DECstation)
DEC: Mach 3.0 (DECstation 5000/25)
DEC: OSF/1 1.2, 1.3, 2.0, 3.*, DEC Unix 4.* (Alpha)
	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, 11.0
	Should build `out-of-the-box'.

	Problems with dynamic loading have been reported under 11, but
	this should compile using the standard dlopen() function set
	(rather than the 10.20 shl_load() function set).  More details of
	any difficulties would be appreciated.

IBM: AIX 3.2, 4.1
	Should build `out-of-the-box', but --enable-zsh-mem will not work.

	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 appear to be problems using
	--enable-dynamic (the default) with gcc (version was 2.7.2.3) in
	4.1, though native cc works. More information about this problem
	would be appreciated.

Linux: Linux (i[345]86,various Pentia,AMD K6/2)
	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.*
	Should build `out-of-the-box'.

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

OpenBSD: OpenBSD 2.6
	Should build `out-of-the-box'.

SIEMENS: Reliant UNIX
       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
       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 5.1.1.1, 5.2, 5.3, 6.2, 6.3, 6.5
	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.

Sun: SunOS 4.1.*
	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.*
	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 have been reported using --enable-lfs (the default) to
	enable large file system and integer support on Solaris 2 with gcc.
	Apparently upgrading to gcc version 2.95.2 fixes this.  If this
	is not feasible, configure with --disable-lfs.  We would be
	grateful for more detailed information.
