It's not the credit-giving (typically, authors usually credit themselves in the file header) but the requirement of prominent advertizing. I'm not a license guru, but I think the GPL explicitly forbids extra license requirements above those specified in the GPL itself. So if you want an advertizing clause, you have to use a modified version of the GPL or combine the code with a modified version of the GPL, thus non-GPL. In fact, when I now searched gnu.org, I found this: http://www.gnu.org/licenses/gpl-faq.html#TOCOrigBSD > I see no reason why an advertising clause need cause an issue... > could someone explain it to me? This is most likely not the proper list for general licensing discussions or questions. I'm sure there are better suited lists for that. Christian
