[Help-glpk] Command-line and GPL

[Luca Castelluzzo]

Hi,
I would like to use the GLPK by calling the glpsol command from a Java program 
(through system call) that has to solve a specific MIP problem. This program 
could build a MathProg file on-the-fly, invoke glpsol with its arguments and 
then get the solution from the output file. Therefore, it would be neither 
statically nor dynamically linked to the GLPK.

My question is: am I forced to release this program under the GPL?
I've already read http://www.gnu.org/licenses/gpl-faq.html#MereAggregation but 
it didn't help.

Thanks a lot,
Luca Castelluzzo



Change is good. See what's different about Windows Live Hotmail. Check it out!
