=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 allways 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,
cause *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.
