It may work on other versions, but that's the one we've tested it on.</p> <p>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.</p> <h2 id="Unpacking"><a class="permalink" href="#Unpacking">#</a>Unpacking</h2> <p>To extract an ASCII tar archive on VM/ESA, try this:</p> <pre><code class="plaintext">pax -o to=IBM-1047,from=ISO8859-1 -r < latest.tar</code></pre> <h2 id="Setup-and-utilities"><a class="permalink" href="#Setup-and-utilities">#</a><a id="Setup"></a>Setup and utilities</h2> <p>GNU make for VM/ESA, which may be required for the build of perl, is available from:</p> <pre><code class="plaintext">http://pucc.princeton.edu/~neale/vmoe.html</code></pre> <h2 id="Configure"><a class="permalink" href="#Configure">#</a>Configure</h2> <p>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).</p> <p>There is a "hints" file for vmesa that specifies the correct values for most things. Some things to watch out for are:</p> <ul> <li><p>this port does support dynamic loading but it's not had much testing</p> </li> <li><p>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.</p> </li> <li><p>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.</p> </li> <li><p>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.</p> </li> </ul> <h2 id="testing-anomalies"><a class="permalink" href="#testing-anomalies">#</a><a id="testing"></a>testing anomalies</h2> <p>The `make test` step runs a Perl Verification Procedure, usually before installation. As the 5.6.1 kit was 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:</p> <p>[the list of failures being compiled]</p> <h2 id="Usage-Hints"><a class="permalink" href="#Usage-Hints">#</a><a id="Usage"></a>Usage Hints</h2> <p>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.</p> <p>OpenEdition (UNIX System Services) does not (yet) support the #! means of script invocation. See:</p> <pre><code class="plaintext">head `whence perldoc`</code></pre> <p>for an example of how to use the "eval exec" trick to ask the shell to have perl run your scripts for you.</p> <h1 id="AUTHORS"><a class="permalink" href="#AUTHORS">#</a>AUTHORS</h1> <p>Neale Ferguson.</p> <h1 id="SEE-ALSO"><a class="permalink" href="#SEE-ALSO">#</a><a id="SEE"></a>SEE ALSO</h1> <p><a href="/5.6.2/INSTALL">INSTALL</a>, <a href="/5.6.2/perlport">perlport</a>, <a href="/5.6.2/perlebcdic">perlebcdic</a>.</p> <h2 id="Mailing-list"><a class="permalink" href="#Mailing-list">#</a><a id="Mailing"></a>Mailing list</h2> <p>If you are interested in the VM and OS/390 ports of perl then see the perl-mvs mailing list: The Perl Institute (http://www.perl.org/) maintains a mailing list of interest to all folks building and/or using perl on EBCDIC platforms.
