Okay, I think I've satisfied myself, from the project page: http://savannah.gnu.org/projects/autoconf-archive/ "Every single one of those macros can be re-used without imposing any restrictions whatsoever on the licensing of the generated configure script. In particular, it is possible to use all those macros in configure scripts that are meant for non-free software" > > The only thing to ponder imo is whether we should add intel_ prefixes to > the tools and add all the new files to the install target (probably need > tos shove the data files somewhere in var then).

I'm not really too certain of the correct way to install python scripts, so I've mostly punted on this. My feeling for now is, let's make it work in tree, and when it becomes more useful, make sure it works with make install. > > > > -- > > Ben Widawsky, Intel Open Source Technology Center > > _______________________________________________ > > Intel-gfx mailing list > > Intel-gfx at lists.freedesktop.org > > http://lists.freedesktop.org/mailman/listinfo/intel-gfx > > -- > Daniel Vetter > Software Engineer, Intel Corporation > +41 (0) 79 365 57 48 - http://blog.ffwll.ch -- Ben Widawsky, Intel Open Source Technology Center
