Interesting. This actually i line with what I just read at http://www.gnu.org/licenses/gpl-faq.en.html#GPLStaticVsDynamic : ,---- | Does the GPL have different requirements for statically vs dynamically li= nked modules with a covered work? (#GPLStaticVsDynamic) |=20 | No. Linking a GPL covered work statically or dynamically with | other modules is making a combined work based on the GPL covered | work. Thus, the terms and conditions of the GNU General Public | License cover the whole combination. See also What legal issues | come up if I use GPL-incompatible libraries with GPL software? `---- According to this it seems clear: GPL compatible license.
