Dear GLPK users,

Version 0.04 of Math::GLPK (the Perl module for the GNU Linear 
Programming Kit) is available for downloading from here:

If you are already a happy user of Math::GLPK, then you may not need to 
upgrade. The big improvements happened in the installation: from now the low 
level GLPK wrapper library, Math::GKLP::Solve comes with full support of the 
GLPK API from version 4.4 upwards. For instance, installing Math::GKLP::Solve 
for GLPK v4.7 is as easy as issuing:

 GLPK_VERSION=4.7 perl Makefile.PL
 make test
 make install

The test script (you use "make test", don't you?) is improved to the point 
that API version mismatches can usually be caught at compile time. 

The high-level object-oriented module, Math::GLPK also received numerous minor 
fixes and advanced testing using Test::More.

This release has been extensively tested with GLPK v4.6 and v4.7 on Debian 
GNU/Linux Sarge, but is should work on any other Unices as well.

How to install Math::GLPK:

- download all tar archives from

- first, install Math::GLPK::Solve from Math-GLPK-Solve-0.04.tar.gz. All the
  necessary information can be found in the README and INSTALL files in the
  distribution. You must have GLPK version 4.4 or higher installed on your
  system! Currently not tested on architectures other than Debian GNU/Linux.

- install Math::MatrixSparse from Math-MatrixSparse-0.03.tar.gz. This should
  work fine on all architectures supported by Perl. Note that the version of
  Math::MatrixSparse (version 0.01) found on CPAN is NOT suitable for
  Math::GLPK, you need version 0.03!

- install Math::GLPK from Math-GLPK-0.04.tar.gz as usual...

Testers, contributors, and especially porters are once again highly 
appreciated... If you have problems or suggestions, please, contact me!
