1 | If you read this file _as_is_, just ignore the funny characters you |

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. | |

3df9be30 | 14 | =head2 Building 32-bit Perl in Irix |
469e7be4 JH |
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.) | |
24 | ||
3df9be30 | 25 | =head2 Building 64-bit Perl in Irix |
469e7be4 JH |
26 | |
27 | Use | |
28 | ||
29 | sh Configure -Dcc='cc -64' | |
30 | ||
31 | to compiler Perl 64-bit. | |

3df9be30 | 33 | =head2 About Compiler Versions of Irix |
469e7be4 | 34 | |
3df9be30 | 35 | Some Irix cc versions, e.g. 7.3.1.1m (try cc -version) have been known |
469e7be4 JH |
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>) | |

3df9be30 | 42 | =head2 Linker Problems in Irix |
469e7be4 JH |
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. | |

3df9be30 | 48 | =head2 Malloc in Irix |
469e7be4 JH |
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 | ||
3df9be30 | 55 | For Irix 6.2, you have to have the following patches installed: |
469e7be4 JH |
56 | |
57 | 1404 Irix 6.2 Posix 1003.1b man pages | |
3df9be30 | 58 | 1645 Irix 6.2 & 6.3 POSIX header file updates |
469e7be4 JH |
59 | 2000 Irix 6.2 Posix 1003.1b support modules |
60 | 2254 Pthread library fixes | |
61 | 2401 6.2 all platform kernel rollup | |
62 | ||
3df9be30 JH |
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 | |
469e7be4 JH |
65 | and later are okay. |
