Re: framework

[Saso Kiselkov]

The math is really very simple:

GNUstep: LGPL => links with any license you want
DevIL: LGPL => links with any license you want
GLEW: MIT/BSD => links with any license you want
PRNG: GPL => links ONLY with GPL
NVIDIA Cg => no idea on usage license terms

In other words, you'll have to use GPL for your app. Remember, that GPL 
linking requirements only work from library -> app, i.e. if you link to 
a GPL library, your app has to become GPL. If, however, your app is GPL 
and you link to a non-compatible/proprietary library, that doesn't force 
the library to become GPL. As an example, consider compiling a GPL app 
against Solaris' proprietary libc - that doesn't force the libc to 
become GPL. That means, you don't have to remove the NVIDIA Cg 
dependency if you don't want to.
