[Help-glpk] MySQL Support for GLPK 4.23

[xypron . glpk]

Hello!

I have added MySQL database support to the GNU MathProg language in GLPK 4.23.

Sources are available at 
ftp://87.230.79.59/glpk/glpk-4.23-sql-20071101.tar.gz

Library mysqlclient and header mysql/mysql.h are needed.
For Debian and derivates like Ubuntu:
sudo apt-get libmysqlclient15-dev

In the data section the following commands can be used to fill a set with data 
from a data base query:

dbopen( 'MySQL', 'server', 'database', 'user', 'password');
dbquery(set, 'sql-query');
dbclose;

For an example see 
glpk-4.23-sql-20071101/examples/mysql.mod

Only the Linux makefiles are updated. Windows files remain to be updated.

--enable-mysql has been added to configure.

Next step to do is to enable writing the calculation results to the data base.

I would appreciate Your comments.

Best regards

Xypron
