NAME
     README.irix - Perl version 5 on Irix systems

DESCRIPTION
     This document describes various features of Irix that will
     affect how Perl version 5 (hereafter just Perl) is compiled
     and/or runs.

  Building 32-bit Perl in Irix
     Use

             sh Configure -Dcc='cc -n32'

     to compile Perl 32-bit.  Don't bother with -n32 unless you
     have 7.1 or later compilers (use cc -version to check).

     (Building 'cc -n32' is the default.)

  Building 64-bit Perl in Irix
     Use

             sh Configure -Dcc='cc -64' -Duse64bitint

     This requires require a 64-bit MIPS CPU (R8000, R10000, ...)

     You can also use

             sh Configure -Dcc='cc -64' -Duse64bitall

     but that makes no difference compared with the -Duse64bitint
     because of the "cc -64".

     You can also do

             sh Configure -Dcc='cc -n32' -Duse64bitint

     to use long longs for the 64-bit integer type, in case you
     don't have a 64-bit CPU.

     If you are using gcc, just

             sh Configure -Dcc=gcc -Duse64bitint

     should be enough, the Configure should automatically probe
     for the correct 64-bit settings.

  About Compiler Versions of Irix
     Some Irix cc versions, e.g. 7.3.1.1m (try cc -version) have
     been known to have issues (coredumps) when compiling perl.c.
     If you've used -OPT:fast_io=ON and this happens, try
     removing it.  If that fails, or you didn't use that, then
     try adjusting other optimization options (-LNO, -INLINE, -O3

     to -O2, etcetera).  The compiler bug has been reported to
     SGI.  (Allen Smith <easmith@beatrice.rutgers.edu>)

  Linker Problems in Irix
     If you get complaints about so_locations then search in the
     file hints/irix_6.sh for "lddflags" and do the suggested
     adjustments.  (David Billinghurst
     <David.Billinghurst@riotinto.com.au>)

  Malloc in Irix
     Do not try to use Perl's malloc, this will lead into very
     mysterious errors (especially with -Duse64bitall).

  Building with threads in Irix
     Run Configure with -Duseithreads which will configure Perl
     with the Perl 5.8.0 "interpreter threads", see threads.

     For Irix 6.2 with perl threads, you have to have the
     following patches installed:

             1404 Irix 6.2 Posix 1003.1b man pages
             1645 Irix 6.2 & 6.3 POSIX header file updates
             2000 Irix 6.2 Posix 1003.1b support modules
             2254 Pthread library fixes
             2401 6.2 all platform kernel rollup

     IMPORTANT: Without patch 2401, a kernel bug in Irix 6.2 will
     cause your machine to panic and crash when running threaded
     perl.  Irix 6.3 and later are okay.

         Thanks to Hannu Napari <Hannu.Napari@hut.fi> for the IRIX
         pthreads patches information.

  Irix 5.3
     While running Configure and when building, you are likely to
     get quite a few of these warnings:

       ld:
       The shared object /usr/lib/libm.so did not resolve any symbols.
             You may want to remove it from your link line.

     Ignore them: in IRIX 5.3 there is no way to quieten ld about
     this.

     During compilation you will see this warning from toke.c:

       uopt: Warning: Perl_yylex: this procedure not optimized because it
             exceeds size threshold; to optimize this procedure, use -Olimit option
             with value >= 4252.

     Ignore the warning.

     In IRIX 5.3 and with Perl 5.8.1 (Perl 5.8.0 didn't compile
     in IRIX 5.3) the following failures are known.

      Failed Test                  Stat Wstat Total Fail  Failed  List of Failed
      --------------------------------------------------------------------------
      ../ext/List/Util/t/shuffle.t    0   139    ??   ??       %  ??
      ../lib/Math/Trig.t            255 65280    29   12  41.38%  24-29
      ../lib/sort.t                   0   138   119   72  60.50%  48-119
      56 tests and 474 subtests skipped.
      Failed 3/811 test scripts, 99.63% okay. 78/75813 subtests failed, 99.90% okay.

     They are suspected to be compiler errors (at least the
     shuffle.t failure is known from some IRIX 6 setups) and math
     library errors (the Trig.t failure), but since IRIX 5 is
     long since end-of-lifed, further fixes for the IRIX are
     unlikely.  If you can get gcc for 5.3, you could try that,
     too, since gcc in IRIX 6 is a known workaround for at least
     the shuffle.t and sort.t failures.
