11 | This document describes various features of IBM's Unix operating |
12 | system (AIX) that will affect how Perl version 5 (hereafter just Perl) | |
13 | is compiled and/or runs. | |

15 | =head2 Compiling Perl 5 on AIX | |
16 | ||
d5d9880c | 17 | When compiling Perl, you must use an ANSI C compiler. AIX does not ship |
20d11268 MB |
18 | an ANSI compliant C-compiler with AIX by default, but binary builds of |
19 | gcc for AIX are widely available. | |
20 | ||
21 | At the moment of writing, AIX supports two different native C compilers, | |
22 | for which you have to pay: B<xlc> and B<VAC>. If you decide to use eiter | |
23 | of these two (which is quite a lot easier than using gcc), be sure to | |
24 | upgrade to the latest available patch level. Currently: | |
25 | ||
26 | xlC.C 3.1.4.0 | |
27 | vac.C 4.4.0.3 (5.0 is already available) | |
28 | ||
a318903f MB |
29 | Perl can be compiled with either IBM's ANSI C compiler or with gcc. |
30 | The former is recommended, as not only can it compile Perl with no | |
20d11268 MB |
31 | difficulty, but also can take advantage of features listed later that |
32 | require the use of IBM compiler-specific command-line flags. | |
33 | ||
34 | If you decide to use gcc, make sure your installation is recent and | |
35 | complete, and be sure to read the Perl README file for more gcc-specific | |
36 | details. | |
37 | ||
38 | =head2 OS level | |
39 | ||
40 | Before installing the patches to the IBM C-compiler you need to know the | |
41 | level of patching for the Operating System. IBM's command 'oslevel' will | |
a318903f | 42 | show the base, but is not always complete: |
20d11268 MB |
43 | |
44 | # oslevel | |
45 | 4.3.0.0 | |
46 | # lslpp -l | grep 'bos.rte ' | |
47 | bos.rte 4.3.2.1 COMMITTED Base Operating System Runtime | |
48 | bos.rte 4.3.2.0 COMMITTED Base Operating System Runtime | |

51 | =head2 Building Dynamic Extensions on AIX | |
52 | ||
53 | AIX supports dynamically loadable libraries (shared libraries). | |
54 | Shared libraries end with the suffix .a, which is a bit misleading, | |
a318903f | 55 | because *all* libraries are shared ;-). |

57 | =head2 The IBM ANSI C Compiler | |
58 | ||
59 | All defaults for Configure can be used. | |
60 | ||
61 | If you've chosen to use vac 4, be sure to run 4.4.0.3. Older versions | |
62 | will turn up nasty later on. | |
63 | ||
a318903f MB |
64 | Here's a brief lead of how to upgrade the compiler to the latest |
65 | level. Of course this is subject to changes. You can only upgrade | |
66 | versions from ftp-available updates if the first three digit groups | |
67 | are the same (in where you can skip intermediate unlike the patches | |
68 | in the developer snapshots of perl), or to one version up where the | |
69 | `base' is available. In other words, the AIX compiler patches are | |
70 | cumulative. | |
71 | ||
72 | vac.C.4.4.0.1 => vac.C.4.4.0.3 is OK (vac.C.4.4.0.2 not needed) | |
73 | xlC.C.3.1.3.3 => xlC.C.3.1.4.10 is NOT OK (xlC.C.3.1.4.0 is not available) | |
