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>)
If you get complaints about so_locations then search in the file
hints/irix_6.sh for ``lddflags'' and do the suggested adjustments.

perldoc2tree.cgi: /usr/lib/perl5/5.8.8/pod/perlirix.pod: cannot resolve L in paragraph 31.
Run Configure with -Duseithreads which will configure Perl with
the new Perl 5.8.0 ``interpreter threads'', see threads.
The old Perl 5.005 threads is obsolete, unmaintained, and its use is
discouraged. If you really want it, run Configure with the
-Dusethreads -Duse5005threads options as described in INSTALL.
For either thread model and for Irix 6.2, you have to have the
following patches installed:
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.
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

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.
