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

Perl Programmers Reference Guide PERLIRIX(1)
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.
perl v5.12.5 Last change: 2012-11-03 2
Perl Programmers Reference Guide PERLIRIX(1)
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.
