README.aix - Perl version 5 on IBM Unix (AIX) systems
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.
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: xlc and
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 advan
tage 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.
OS level
Before installing the patches to the IBM C-compiler you
need to know the level of patching for the Operating Sys
tem. 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
#
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 ;-).
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)
