7 README.irix - Perl version 5 on Irix systems
11 This document describes various features of Irix that will affect how Perl
12 version 5 (hereafter just Perl) is compiled and/or runs.
14 =head2 Building 32-bit Perl in Irix
18 sh Configure -Dcc='cc -n32'
20 to compile Perl 32-bit. Don't bother with -n32 unless you have 7.1
21 or later compilers (use cc -version to check).
23 (Building 'cc -n32' is the default.)
25 =head2 Building 64-bit Perl in Irix
29 sh Configure -Dcc='cc -64'
31 to compiler Perl 64-bit.
33 =head2 About Compiler Versions of Irix
35 Some Irix cc versions, e.g. 7.3.1.1m (try cc -version) have been known
36 to have issues (coredumps) when compiling perl.c. If you've used
37 -OPT:fast_io=ON and this happens, try removing it. If that fails, or
38 you didn't use that, then try adjusting other optimization options
39 (-LNO, -INLINE, -O3 to -O2, etcetera). The compiler bug has been
40 reported to SGI. (Allen Smith <easmith@beatrice.rutgers.edu>)
42 =head2 Linker Problems in Irix
44 If you get complaints about so_locations then search in the file
45 hints/irix_6.sh for "lddflags" and do the suggested adjustments.
46 (David Billinghurst <David.Billinghurst@riotinto.com.au>)
50 Do not try to use Perl's malloc, this will lead into very mysterious
51 errors (especially with -Duse64bitall).
53 =head2 Building with threads
55 For Irix 6.2, you have to have the following patches installed:
57 1404 Irix 6.2 Posix 1003.1b man pages
58 1645 Irix 6.2 & 6.3 POSIX header file updates
59 2000 Irix 6.2 Posix 1003.1b support modules
60 2254 Pthread library fixes
61 2401 6.2 all platform kernel rollup
63 IMPORTANT: Without patch 2401, a kernel bug in Irix 6.2 will cause
64 your machine to panic and crash when running threaded perl. Irix 6.3
