-README.os390 - building and installing Perl for OS/390.

=head1 SYNOPSIS
This document will help you Configure, build, test and install Perl
-on OS/390 Unix System Services.

=head1 DESCRIPTION
You may need to carry out some system configuration tasks before
running the Configure script for Perl.

+=head2 Tools
+
+The z/OS Unix Tools and Toys list may prove helpful and contains links
+to ports of much of the software helpful for building Perl.

+=head2 Unpacking Perl distribution on OS/390
+
+If using ftp remember to transfer the distribution in binary format.
Gunzip/gzip for OS/390 is discussed at:

+ http://www.ibm.com/servers/eserver/zseries/zos/unix/bpxa1ty1.html
to extract an ASCII tar archive on OS/390, try this:
pax -o to=IBM-1047,from=ISO8859-1 -r < latest.tar
-=head2 Setup and utilities
+or
+
+ zcat latest.tar.Z | pax -o to=IBM-1047,from=ISO8859-1 -r
+
+If you get lots of errors of the form
+
+ tar: FSUM7171 ...: cannot set uid/gid: EDC5139I Operation not permitted
+
+you didn't read the above and tried to use tar instead of pax, you'll
+first have to remove the (now corrupt) perl directory
+
+ rm -rf perl-...
+
+and then use pax.

Be sure that your yacc installation is in place including any necessary
parser template files. If you have not already done so then be sure to:

Some of the parser default template files in /samples are needed in /etc.
In particular be sure that you at least copy /samples/yyparse.c to /etc

This has to be done before running Configure the first time. If you failed
to do so then the easiest way to re-Configure Perl is to delete your
misconfigured build root and re-extract the source from the tar ball.
If in trying to use Perl you see an error message similar to:

by re building the GNU make utility for OS/390 from a source code kit.

+=head2 Installation Anomalies with Perl on OS/390
The installman script will try to run on OS/390. There will be fewer errors
if you have a roff utility installed. You can obtain GNU groff from the
Redbook SG24-5944-00 ftp site.

When using perl on OS/390 please keep in mind that the EBCDIC and ASCII
character sets are different. See perlebcdic.pod for more on such character

working with Perl on USS.
