- =head1 NAME
-
- README.aix - Perl version 5 on IBM Unix (AIX) systems
-
- =head1 DESCRIPTION
-
- This document describes various features of IBM's Unix operating
- system (AIX) that will affect how Perl version 5 (hereafter just Perl)
- is compiled and/or runs.
-
- =head2 Compiling Perl 5 on AIX
-
- When compiling Perl, you must use an ANSI C compiler. AIX does not ship
- an ANSI compliant C-compiler with AIX by default, but binary builds of
- gcc for AIX are widely available.
-
- At the moment of writing, AIX supports two different native C compilers,
- for which you have to pay: B<xlc> and B<VAC>. If you decide to use eiter
- of these two (which is quite a lot easier than using gcc), be sure to
- upgrade to the latest available patch level. Currently:
-
- xlC.C 3.1.4.0
- vac.C 4.4.0.3 (5.0 is already available)
-
- Perl can be compiled with either IBM's ANSI C compiler or with gcc.
- The former is recommended, as not only can it compile Perl with no
- difficulty, but also can take advantage of features listed later that
- require the use of IBM compiler-specific command-line flags.
-
- If you decide to use gcc, make sure your installation is recent and
- complete, and be sure to read the Perl README file for more gcc-specific
- details.
-
- =head2 OS level
-
- Before installing the patches to the IBM C-compiler you need to know the
- level of patching for the Operating System. IBM's command 'oslevel' will
- show the base, but is not always complete:
-
- # oslevel
- 4.3.0.0
- # lslpp -l | grep 'bos.rte '
- bos.rte 4.3.2.1 COMMITTED Base Operating System Runtime
- bos.rte 4.3.2.0 COMMITTED Base Operating System Runtime
- #
-
- =head2 Building Dynamic Extensions on AIX
-
- AIX supports dynamically loadable libraries (shared libraries).
- Shared libraries end with the suffix .a, which is a bit misleading,
- because *all* libraries are shared ;-).
-
- =head2 The IBM ANSI C Compiler
-
- All defaults for Configure can be used.
-
- If you've chosen to use vac 4, be sure to run 4.4.0.3. Older versions
- will turn up nasty later on.
-
- Here's a brief lead of how to upgrade the compiler to the latest
- level. Of course this is subject to changes. You can only upgrade
- versions from ftp-available updates if the first three digit groups
- are the same (in where you can skip intermediate unlike the patches
- in the developer snapshots of perl), or to one version up where the
- `base' is available. In other words, the AIX compiler patches are
- cumulative.
-
- vac.C.4.4.0.1 => vac.C.4.4.0.3 is OK (vac.C.4.4.0.2 not needed)
- xlC.C.3.1.3.3 => xlC.C.3.1.4.10 is NOT OK (xlC.C.3.1.4.0 is not available)
