People build commercial applications all the time under Linux. These applications implicitly call the Linux kernel, and perhaps explicitly call on a variety of commands (which are really applications) like "mv", "cp" and so on. Yet these commercial applications are not under the GPL. I think Luca's situation is similar.
Another example, a lot of ISP providers are able to offer Jabber, MySQL and other services that are GPL'd. Customers are invited to write (non-GPL'd) applications that make use of these services. Such as an MS Access and Excel application that links to a MySQL instance on an ISP provider. -Marc -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Andrew Makhorin Sent: Friday, June 22, 2007 1:39 PM To: Luca Castelluzzo Cc: [email protected] Subject: Re: [Help-glpk] Command-line and GPL > 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.

Why do not implement your program under GPL? It would be in the spirit of GNU software. _______________________________________________ Help-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-glpk ---------------------------------------------------------------------------- This e-mail and any attachments may be confidential or legally privileged.
