7 | README.aix - Perl version 5 on IBM Unix (AIX) systems |
8 | |
9 | =head1 DESCRIPTION |
10 | |
a318903f |
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. |
20d11268 |
14 | |
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 |
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 |
60ecc970 |
27 | vac.C 4.4.0.3 or 5.0.2.0 |
20d11268 |
28 | |
a318903f |
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 |
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 |
60ecc970 |
36 | details. Please report any hoops you had to jump through to the development |
37 | team. |

38 | |
39 | =head2 OS level |
40 | |
41 | Before installing the patches to the IBM C-compiler you need to know the |
42 | level of patching for the Operating System. IBM's command 'oslevel' will |
a318903f |
43 | show the base, but is not always complete: |
20d11268 |
44 | |
45 | # oslevel |
46 | 4.3.0.0 |
47 | # lslpp -l | grep 'bos.rte ' |
48 | bos.rte 4.3.2.1 COMMITTED Base Operating System Runtime |
49 | bos.rte 4.3.2.0 COMMITTED Base Operating System Runtime |

52 | =head2 Building Dynamic Extensions on AIX |
53 | |
54 | AIX supports dynamically loadable libraries (shared libraries). |
55 | Shared libraries end with the suffix .a, which is a bit misleading, |
a318903f |
56 | because *all* libraries are shared ;-). |
20d11268 |
57 | |
58 | =head2 The IBM ANSI C Compiler |
59 | |
60 | All defaults for Configure can be used. |
61 | |
62 | If you've chosen to use vac 4, be sure to run 4.4.0.3. Older versions |
60ecc970 |
63 | will turn up nasty later on. For vac 5 be sure to run at least 5.0.1.0. |
20d11268 |
64 | |
a318903f |
65 | Here's a brief lead of how to upgrade the compiler to the latest |
66 | level. Of course this is subject to changes. You can only upgrade |
67 | versions from ftp-available updates if the first three digit groups |
68 | are the same (in where you can skip intermediate unlike the patches |
69 | in the developer snapshots of perl), or to one version up where the |
70 | `base' is available. In other words, the AIX compiler patches are |
71 | cumulative. |
72 | |
73 | vac.C.4.4.0.1 => vac.C.4.4.0.3 is OK (vac.C.4.4.0.2 not needed) |
74 | xlC.C.3.1.3.3 => xlC.C.3.1.4.10 is NOT OK (xlC.C.3.1.4.0 is not available) |

151 | Threads seem to work OK, though at the moment not all tests pass when |

155 | |
60ecc970 |
156 | If your AIX is installed with 64-bit support, you can expect 64bit |
157 | configurations to work. In combination with threads some tests might still fail. |
