=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)
