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 <[EMAIL PROTECTED]>
for the contribution, Rafael Laboissiere <[EMAIL PROTECTED]>
for useful advices concerning the shared library support under
GNU/Linux, and Vijay Patil <[EMAIL PROTECTED]> 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
library
--without-zlib Disable using the zlib data compression
library
--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
