hello debian-legal, as a part of my intent to package openscad (#583476), i want to ask you for help with the package's licensing. as outlined in the itp, the package is gpl-2+ itself and depends heavily on libcgal, which is qpl and thus in non-free, which sends openscad to contrib. openscad has a cgal exception on its license, and some time ago i contacted its only gpl dependency's author, who re-licensed his library to gpl-2+ with cgal exception too. so far, so good. now there is a very particular file in the openscad library, src/OGL_helper.h. it is derived from an OGL_helper.h in cgal, which is qpl licensed. i don't think that could bring anyone in trouble (qpl is ok with being modified and linked against, and whoever brings gpl into the end result had to agree to use parts of cgal anyway), but it's hard to represent in the debian package. i've come up with various ways, of which i'm not sure which will work or which of the working is best: * upstream author both the openscad author and i have tried to contact the author of the original OGL_helper.h file. if he agreed to dual-license it qpl and gpl, we'd all be fine. the modified version could stay in openscad, and there would be much rejoycing. * technical solution if the modifications could be split out from OGL_helper.h by means of c++, we would still link against the qpl version statically, but we wouldn't have to ship qpl source code in openscad and could rely on it being provided by the non-free build dependency. if it was trivial, the openscad authors would already have done it, and my c++ fu is not strong enough for such a task. now for the less elegant solutions... * a patch the debian package could contain a patch against the cgal version. that would be more or less equivalent to the technical solution, but far less elegant; plus, i wouldn't dare to judge the license situation of the resulting intermediate file that gets created on the build server. * declaring openscad nonfree we ship the qpl file, we are non-free. problem solved. i am still working on the version of the package that is to be released as 2011.12-1, a preliminary version of the copyright file is attached. the other FIXME it contains (contrib/OpenSCAD.xml) will, as i hope, be resolved by the file's author (who is active on the project's mailing list). do you know any other way out, or have other suggestions on how to solve that? regards chrysn -- I shouldn't have written all those tank programs. -- Kevin Flynn
