From mboxrd@z Thu Jan 1 00:00:00 1970 From: Nicolai Hanssing To: gsl-discuss@sources.redhat.com Subject: GPL - GSL and derivative work. Date: Wed, 19 Dec 2001 13:20:00 -0000 Message-id: References: <15175.31246.375178.387008@debian> X-SW-Source: 2001/msg00282.html Dear listmembers I was wondering what the authors of gsl, consideres to be derivative work. An example follows: -------- A firm writes an application, that uses/links with gsl. The firm does not however modify the gsl-source. Now the firm wants to sell/distribute the application, then what is forced by the GPL? The firm, *) Has to make the source of the application publicly available? I.e. will rewrite the application to not use GSL .... :-) *) Has to distribute the source of gsl along with the application? *) Has to include the GPL-license in the documaentation? *) Must not advertize with the use of GSL without permission? *) anything else... I'm currently writing my thesis in cooperation with a firm, and I'm using gsl, so what are the firm's possibilities afterwards [of course the source is public - it's a thesis] for future use?
