NAME
perlvmesa - building and installing Perl for VM/ESA.
SYNOPSIS
This document will help you Configure, build, test and install Perl on VM/ESA.
DESCRIPTION
This is a fully ported perl for VM/ESA 2.3.0. It may work on other versions, but that's the one we've tested
it on.
If you've downloaded the binary distribution, it needs to be installed below /usr/local. Source code
distributions have an automated "make install" step that means you do not need to extract the source code
below /usr/local (though that is where it will be installed by default). You may need to worry about the
networking configuration files discussed in the last bullet below.
Unpacking Perl Distribution on VM/ESA
To extract an ASCII tar archive on VM/ESA, try this:
pax -o to=IBM-1047,from=ISO8859-1 -r < latest.tar
Setup Perl and utilities on VM/ESA
GNU make for VM/ESA, which may be required for the build of perl, is available from:
<http://vm.marist.edu/~neale/vmoe.html>
Configure Perl on VM/ESA
Once you've unpacked the distribution, run Configure (see INSTALL for full discussion of the Configure
options), and then run make, then "make test" then "make install" (this last step may require UID=0
privileges).
There is a "hints" file for vmesa that specifies the correct values for most things. Some things to watch out
for are:
· this port does support dynamic loading but it's not had much testing
· Don't turn on the compiler optimization flag "-O". There's a bug in the compiler (APAR PQ18812) that
generates some bad code the optimizer is on.
· As VM/ESA doesn't fully support the fork() API programs relying on this call will not work. I've replaced
fork()/exec() with spawn() and the standalone exec() with spawn(). This has a side effect when opening
unnamed pipes in a shell script: there is no child process generated under.
· At the moment the hints file for VM/ESA basically bypasses all of the automatic configuration process.
This is because Configure relies on: 1. The header files living in the Byte File System (you could put the
there if you want); 2. The C preprocessor including the #include statements in the preprocessor output
(.i) file.
Testing Anomalies of Perl on VM/ESA
The "make test" step runs a Perl Verification Procedure, usually before installation. As the 5.6.1 kit was
being assembled the following "failures" were known to appear on some machines during "make test" (mostly due
to ASCII vs. EBCDIC conflicts), your results may differ:

Usage Hints for Perl on VM/ESA
When using perl on VM/ESA please keep in mind that the EBCDIC and ASCII character sets are different. Perl
INSTALL, perlport, perlebcdic.
