NAMEperlirix - Perl version 5 on Irix systems
DESCRIPTIONThis 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 IrixUse
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 IrixUse
sh Configure -Dcc='cc -64' -Duse64bitint
This requires require a 64-bit
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
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 IrixSome Irix cc versions, e.g. 220.127.116.11m (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
Linker Problems in IrixIf 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 IrixDo not try to use Perl's malloc, this will lead into very mysterious errors (especially with -Duse64bitall).
Building with threads in IrixRun 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
Thanks to Hannu Napari <Hannu.Napari@hut.fi> for the IRIX pthreads patches information.
Irix 5.3While 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
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.
