perlvmesa - building and installing Perl for VM/ESA.
This document will help you Configure, build, test and install Perl on VM/ESA.
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.
To extract an ASCII tar archive on VM/ESA, try this:
pax -o to=IBM-1047,from=ISO8859-1 -r < latest.tar
GNU make for VM/ESA, which may be required for the build of perl, is available from:
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:
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]
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.
