| 7 | README.irix - Perl version 5 on Irix systems |
| 8 | |
| 9 | =head1 DESCRIPTION |
| 10 | |
| 11 | This document describes various features of Irix that will affect how Perl |
| 12 | version 5 (hereafter just Perl) is compiled and/or runs. |
| 13 | |
| 14 | =head2 Building 32-bit |
| 15 | |
| 16 | Use |
| 17 | |
| 18 | sh Configure -Dcc='cc -n32' |
| 19 | |
| 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). |
| 22 | |
| 23 | (Building 'cc -n32' is the default.) |

25 | =head2 Building 64-bit |
| 469e7be4 |
26 | |
| 27 | Use |
| 28 | |
| 29 | sh Configure -Dcc='cc -64' |
| 30 | |
| 31 | to compiler Perl 64-bit. |
| 32 | |
| 33 | =head2 About Compiler Versions |
| 34 | |
| 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>) |
| 41 | |
| 42 | =head2 Linker Problems |
| 43 | |
| 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>) |

| 48 | =head2 Malloc |
| 49 | |
| 50 | Do not try to use Perl's malloc, this will lead into very mysterious |
| 51 | errors (especially with -Duse64bitall). |
| 52 | |
| 53 | =head2 Building with threads |
| 54 | |
| 55 | For IRIX 6.2, you have to have the following patches installed: |
| 56 | |
| 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 |
| 62 | |
| 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 |
| 65 | and later are okay. |
