GLPK 4.28 -- Release Information

Release date: Mar 25, 2008

GLPK (GNU Linear Programming Kit) is intended for solving large-scale
linear programming (LP), mixed integer linear programming (MIP), and
other related problems. It is a set of routines written in ANSI C and
organized as a callable library.

In this release:

        The iODBC and MySQL table drivers, which allows transmitting
        data between MathProg model objects and relational databases,
        were re-implemented to replace a static linking by a dynamic
        linking to corresponding shared libraries.
        Many thanks to Heinrich Schuchardt <address@hidden>
        for the contribution, Rafael Laboissiere <address@hidden>
        for useful advices concerning the shared library support under
        GNU/Linux, and Vijay Patil <address@hidden> for testing
        this feature under Windows XP.

        A new optional feature was added to the package. This feature
        is based on the zlib data compression library and allows GLPK
        API routines and the stand-alone solver to read and write
        compressed data files performing compression/decompression "on
        the fly" (compressed data files are recognized by suffix `.gz'
        in the file name). It may be useful in case of large MPS files
        to save the disk space (up to ten times).

        The `configure' script was re-implemented. Now it supports the
        following specific options:

        --with-gmp           Enable using the GNU MP bignum library
        --without-gmp        Disable using the GNU MP bignum library
        --with-zlib          Enable using the zlib data compression
        --without-zlib       Disable using the zlib data compression
        --enable-dl          Enable shared library support (auto check)
        --enable-dl=ltdl     Enable shared library support (GNU)
        --enable-dl=dlfcn    Enable shared library support (POSIX)
        --disable-dl         Disable shared library support
        --enable-odbc        Enable using ODBC table driver
        --disable-odbc       Disable using ODBC table driver
        --enable-mysql       Enable using MySQL table driver
        --disable-mysql      Disable using MySQL table driver
