.SH NAME
perlirix \- Perl version 5 on Irix systems
.SH DESCRIPTION
.IX Header "DESCRIPTION"
This document describes various features of Irix that will affect how Perl
version 5 (hereafter just Perl) is compiled and/or runs.
.SS "Building 32\-bit Perl in Irix"
.IX Subsection "Building 32-bit Perl in Irix"
Use
.PP
.Vb 1
\& sh Configure \-Dcc=\*(Aqcc \-n32\*(Aq
.Ve
.PP
to compile Perl 32\-bit. Don't bother with \-n32 unless you have 7.1
or later compilers (use cc \-version to check).
.PP
(Building 'cc \-n32' is the default.)
.SS "Building 64\-bit Perl in Irix"
.IX Subsection "Building 64-bit Perl in Irix"
Use
.PP
.Vb 1
\& sh Configure \-Dcc=\*(Aqcc \-64\*(Aq \-Duse64bitint
.Ve
.PP
This requires require a 64\-bit MIPS CPU (R8000, R10000, ...)
.PP
You can also use
.PP
.Vb 1
\& sh Configure \-Dcc=\*(Aqcc \-64\*(Aq \-Duse64bitall
.Ve
.PP
but that makes no difference compared with the \-Duse64bitint because
of the \f(CW\*(C`cc \-64\*(C'\fR.
.PP
You can also do
.PP
.Vb 1
\& sh Configure \-Dcc=\*(Aqcc \-n32\*(Aq \-Duse64bitint
.Ve
.PP
to use long longs for the 64\-bit integer type, in case you don't
have a 64\-bit CPU.
.PP
If you are using gcc, just
.PP
.Vb 1
\& sh Configure \-Dcc=gcc \-Duse64bitint
.Ve
.PP
should be enough, the Configure should automatically probe for the
correct 64\-bit settings.
.SS "About Compiler Versions of Irix"
.IX Subsection "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, et cetera). The compiler bug has been
reported to SGI. (Allen Smith <easmith@beatrice.rutgers.edu>)
.SS "Linker Problems in Irix"
.IX Subsection "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>)
.SS "Malloc in Irix"
.IX Subsection "Malloc in Irix"
Do not try to use Perl's malloc, this will lead into very mysterious
errors (especially with \-Duse64bitall).
.SS "Building with threads in Irix"
.IX Subsection "Building with threads in Irix"
Run Configure with \-Duseithreads which will configure Perl with
the Perl 5.8.0 "interpreter threads", see threads.
.PP
For Irix 6.2 with perl threads, you have to have the following
patches installed:
.PP
.Vb 5
\& 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
.Ve
.PP
\&\fBIMPORTANT\fR: 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.
.PP
.Vb 2
\& Thanks to Hannu Napari <Hannu.Napari@hut.fi> for the IRIX
\& pthreads patches information.
.Ve
.SS "Irix 5.3"
.IX Subsection "Irix 5.3"
While running Configure and when building, you are likely to get
quite a few of these warnings:
.PP
.Vb 3
\& ld:
\& The shared object /usr/lib/libm.so did not resolve any symbols.
\& You may want to remove it from your link line.
.Ve
.PP
Ignore them: in IRIX 5.3 there is no way to quieten ld about this.
.PP
During compilation you will see this warning from toke.c:
.PP
.Vb 3
\& uopt: Warning: Perl_yylex: this procedure not optimized because it
\& exceeds size threshold; to optimize this procedure, use \-Olimit
\& option with value >= 4252.
.Ve
.PP
Ignore the warning.
.PP
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.
.PP
.Vb 8
\& Failed Test Stat Wstat Total Fail Failed|Failing List
\& \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-
\& ../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.
.Ve
.PP
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.
