I am afraid that this is not enough, unfortunately... :-( This kind move from upstream solves the incompatibility between Gmsh and OCE/OpenCASCADE, but there are other parts of the issue.

I think that this part of the issue will be relevant for the m68k architecture, as long as gmsh is still distributed for that unofficial architecture. Something that is *not* legally distributable does *not* magically become distributable, just because the architecture is not officially supported by the Debian Project... This part of the issue may be irrelevant for the release of wheezy, but not generally irrelevant: I think you should have gmsh removed from the m68k architecture, in order to make this part of the issue really go away. > > So, I think the bug is resolved. There seem to be other GPL-licensed libraries linked with gmsh: libcholmod1.7.1 (some parts are GPL-licensed) libumfpack5.4.0 (UMFPACK is GPL-licensed) http://packages.debian.org/changelogs/pool/main/s/suitesparse/current/copyright Please correct me if I am wrong. Linking with these libraries seem to still make the GPL-incompatibility of OCE/OpenCASCADE very relevant, unfortunately. If this is really the case, then the possible solutions I can think of are: (A) Open CASCADE S.A.S. should be contacted and persuaded to re-license Open CASCADE Technology under GPLv2-and-v3-compatible terms. (B) Open CASCADE Technology should be substituted with a GPLv2-and-v3-compatible replacement, if any is available. (C) CHOLMOD and UMFPACK copyright holders should be asked to re-license these libraries under the GNU LGPL. (D) CHOLMOD and UMFPACK copyright holders should be asked to add a license exception that gives permission to link these libraries with code released under the OCTPL. > > I am going to decrease the severity of the bug I don't think the severity of the bug has changed in any way. > and close it by the next upload.
