NAME
     README.vmesa - 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:

     o   this port does support dynamic loading but it's not had
         much testing

     o   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.

     o   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.

     o   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:

     [the list of failures being compiled]

  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 builtin
     functions that may behave differently under EBCDIC are
     mentioned in the perlport.pod document.

     OpenEdition (UNIX System Services) does not (yet) support
     the #! means of script invocation.  See:

         head `whence perldoc`

     for an example of how to use the "eval exec" trick to ask
     the shell to have perl run your scripts for you.
