Dear trustees, 1) opencascade is a huge 3d-cad-kernel library with its own license (similar to lgpl but not really compatible to anything imho) 2) freecad, a cad program, is part lgpl and part gpl 3) freecad uses opencascade 4) freecad uses gpl libraries (coin 3d) Right now opencascade and freecad are in the sci overlay. From a purely technical point of view it would be nice to have them in the main tree, but as you can see the licensing situation is more than screwed up. What shall / can we do with it? This is (as far as I am concerned) in no way urgent, so take your time. Here are some pointers: [1] http://www.opencascade.org/ the OpenCascade homepage [2] http://www.opencascade.org/getocc/license/ the OpenCascade license (note that it is NOT clear whether the "preamble" is part of the license!) [3] http://www.opencascade.org/occt/faq/ [4] http://www.opencascade.org/org/forum/thread_15859/ Forum discussion about the license preamble [5] http://sourceforge.net/apps/mediawiki/free-cad/index.php?title=Main_Page [6] http://sourceforge.net/apps/mediawiki/free-cad/index.php?title=Licence [7] http://www.coin3d.org/licensing/ [8] https://bugzilla.redhat.com/show_bug.cgi?id=459125 [9] http://old.nabble.com/opencascade-license-in-squeeze-td27571525.html
More info about the OCCT Public Licence: * neither FSF nor OSI have approved of it so far; * Debian had a lenghtly thread[1] about it and decided it is a non-free license. [1] http://lists.debian.org/debian-legal/2007/12/msg00066.html That's the most time I can spare on this ATM.
I put it on the agenda for the Feb Trustee meeting; http://www.gentoo.org/foundation/en/minutes/2011/201102_trustees_agenda.xml
maybe some one can help us. i have request this in main portage tree since a while. http://bugs.gentoo.org/show_bug.cgi?id=291161 but nothing work really fine. in the science overlay the ebuild compile fine but it dont work. some function are quite missing. maybe some developer can improve this and add it to the portage tree. thanks
Just a note that in the Feb trustees meeting it was decided that it was fine to put these packages in portage, though with restrictions on mirroring and bindist: http://www.gentoo.org/foundation/en/minutes/2011/20110220_trustees.meeting_log.txt
Meaning we can resolve this. :)

There's also no real rationale for it in the meeting minutes.

Opencascade itself may or may not be free, but it seems redistributable. So the only debate there should be license group inclusion (best not to treat as free, as the documenting changes stuff would catch people by surprise).
I just found this: Since the version 6.7.0 Open CASCADE Technology is available under GNU Lesser General Public License (LGPL) version 2.1 with additional exception. Previous OCCT releases are licensed under Open CASCADE Technology Public License. Source: http://www.opencascade.org/getocc/license/ I think this means the bug coudl be closed now ^^
Closing bug since upstream relicensed freely.
