NAME
README.os400 - Perl version 5 on OS/400
DESCRIPTION
This document describes various features of IBM's OS/400
operating system that will affect how Perl version 5
(hereafter just Perl) is compiled and/or runs.
By far the easiest way to build Perl for OS/400 is to use
the PASE (Portable Application Solutions Environment), for
more information see
http://www.iseries.ibm.com/developer/factory/pase/index.html
This environment allows one to use AIX APIs while
programming, and it provides a runtime that allows AIX
binaries to execute directly on the PowerPC iSeries.
Compiling Perl for OS/400 PASE
The recommended way to build Perl for the OS/400 PASE is to
build the Perl 5 source code (release 5.8.1 or later) under
AIX.
The trick is to give a special parameter to the Configure
shell script when running it on AIX:
sh Configure -DPASE ...
The default installation directory of Perl under PASE is
/QOpenSys/perl. This can be modified if needed with
Configure parameter -Dprefix=/some/dir.
Starting from OS/400 V5R2 the IBM Visual Age compiler is
supported on OS/400 PASE, so it is possible to build Perl
natively on OS/400. The easier way, however, is to compile
in AIX, as just described.
If you don't want to install the compiled Perl in AIX into
/QOpenSys (for packaging it before copying it to PASE), you
can use a Configure parameter:
-Dinstallprefix=/tmp/QOpenSys/perl. This will cause the
"make install" to install everything into that directory,
while the installed files still think they are (will be) in
/QOpenSys/perl.
If building natively on PASE, please do the build under the
/QOpenSys directory, since Perl is happier when built on a
case sensitive filesystem.
Installing Perl in OS/400 PASE
If you are compiling on AIX, simply do a "make install" on
the AIX box. Once the install finishes, tar up the
/QOpenSys/perl directory. Transfer the tarball to the
OS/400 using FTP with the following commands:

Perl Programmers Reference Guide PERLOS400(1)
> binary
> site namefmt 1
> put perl.tar /QOpenSys
Once you have it on, simply bring up a PASE shell and
extract the tarball.
If you are compiling in PASE, then "make install" is the
only thing you will need to do.
The default path for perl binary is /QOpenSys/perl/bin/perl.
You'll want to symlink /QOpenSys/usr/bin/perl to this file
so you don't have to modify your path.
Using Perl in OS/400 PASE
Perl in PASE may be used in the same manner as you would use
Perl on AIX.
Scripts starting with #!/usr/bin/perl should work if you
have /QOpenSys/usr/bin/perl symlinked to your perl binary.
This will not work if you've done a setuid/setgid or have
environment variable PASE_EXEC_QOPENSYS="N". If you have
V5R1, you'll need to get the latest PTFs to have this
feature. Scripts starting with #!/QOpenSys/perl/bin/perl
should always work.
Known Problems
When compiling in PASE, there is no "oslevel" command.
Therefore, you may want to create a script called "oslevel"
that echoes the level of AIX that your version of PASE
runtime supports. If you're unsure, consult your
documentation or use "4.3.3.0".
If you have test cases that fail, check for the existence of
spool files. The test case may be trying to use a syscall
that is not implemented in PASE. To avoid the SIGILL, try
setting the PASE_SYSCALL_NOSIGILL environment variable or
have a handler for the SIGILL. If you can compile programs
for PASE, run the config script and edit config.sh when it
gives you the option. If you want to remove fchdir(), which
isn't implement in V5R1, simply change the line that says:
d_fchdir='define'
to
d_fchdir='undef'
and then compile Perl. The places where fchdir() is used
have alternatives for systems that do not have fchdir()
available.

Perl on ILE
There exists a port of Perl to the ILE environment. This
port, however, is based quite an old release of Perl, Perl
5.00502 (August 1998). (As of July 2002 the latest release
of Perl is 5.8.0, and even 5.6.1 has been out since April
2001.) If you need to run Perl on ILE, though, you may need
this older port: http://www.cpan.org/ports/#os400 Note that
any Perl release later than 5.00502 has not been ported to
ILE.
If you need to use Perl in the ILE environment, you may want
to consider using Qp2RunPase() to call the PASE version of
Perl.
