This is the Math::Random module with shared libraries compiled for
MacPerl. Shared libraries run only on PPC and CFM68K versions, not
non-CFM 68K versions.
Installing the files in "blib:lib" -
Installing into your site_perl directory is best, as opposed to mucking up
{MACPERL}lib -
{MACPERL}site_perl:Math:Random.pm
{MACPERL}site_perl:MacCFM68K:auto:Math:Random:Random
{MACPERL}site_perl:MacPPC:auto:Math:Random:Random
This distribution was packed with Chris Nandor's 'targzipme' script. I
highly recommend using, at the very least, the 'untargzipme' script to do
the reverse. If you are downloading with a browser, and your prefs are set
to launch Stuffit Expander on a .tar.gz file, be advised that the two
shared libraries should also be dropped on Stuffit Expander manually,
after the main distribution is unpacked, because they are encoded.
Testing -
The file "example.pl" is original. It's more of a demo, but serves as a
useful test, obviously. I also included another file, "defaults.t" in
directory "t", which tests the default exports.
This distribution was prepared for Perl (not by me) with the assistance of
SWIG, the Simplified Interface Wrapper Generator. If you're interested in
details of what SWIG-generated code looks like, examine "wrapper.c".
Special Notes:
(1) I needed to build a new CFM MathLib in order to get the CFM library to
link. In a nutshell, I implemented a MathLibCFM68K with far data. I have
no reason to believe that this won't work; OTOH, I can't test it. If
you're a CFM type, and you've tested this build, please let me know.
Thanks.
(2) Also, for the edification of XS enthusiasts, it was necessary to place
the math library before PerlStub (the Perl library) in the link order, in
order to ensure that the shared library would import math functions such as
pow() and sqrt() from the math library, and not the builtins from Perl. The
problem was identified using the DumpPEF tool in MPW. If you're building
XS, and your libraries compile and link, but don't load, check your
imports.
