[LLVMdev] GPL licensing issues or can GCC be used with llvm for a commercial application?

If you distribute the GPLed library and the proprietary application separately, and make sure that they are linked at installation time, the link step creates a derived work indeed but that's inconsequential because it isn't redistributed. IANAL etc., and there are issues regarding the use of interface files (.h files etc.) from proprietary code, but it should hold up well enough. (Not that I don't like the intentions of the FSF. I just don't think their legal strategy will hold up in the long run.)> I'd suggest consult a good lawyer instead, without even trying to > interpret anything by yourself.I'd suggest doing both. The interpretation may be wrong, but it might help get the lawyer thinking outside preestablished boundaries. That would be crucial if these boundaries originated e.g. in what the FSF has published.
