Package: salome-gui
Version: 6.5.0-1
Severity: serious
Justification: Policy 2.2.1
Hello Debian Science Maintainers,
thanks for your effort to reintroduce SALOME into Debian.
However, it seems to me that one of the licensing issues that
affected the previous package [1] is still present in the
current salome-gui package.
[1] http://bugs.debian.org/619662
Indeed, salome-gui is licensed under the terms of the GNU LGPL v2.1,
but links with libcos4-1/libomniorb4-1, which include [2] files
released under the terms of the GNU GPL v2 or later.

http://packages.debian.org/changelogs/pool/main/o/omniorb-dfsg/current/copyright
This means that package salome-gui is effectively under the GNU GPL
(v2 or later).
On the other hand, salome-gui links with liboce-* packages, which
are released under the terms of the OCTPL v6.3 [3], a GPL-incompatible
license.
[3] http://packages.debian.org/changelogs/pool/main/o/oce/current/copyright
As a consequence, I would say that salome-gui (the binary package) is
currently undistributable, as it links with both a GPLv2-licensed
library and a GPLv2-incompatible one.
Possible solutions, in descending order of desirability:
(A) Open CASCADE S.A.S. should be contacted and persuaded to
re-license Open CASCADE Technology under GPLv2-and-v3-compatible terms.
(B) liboce-* packages should be substituted with a
GPLv2-and-v3-compatible replacement, if any is available.
(C) omniORB copyright holders should be asked to add license
exceptions that give permission to link their work with code released
under the OCTPL.
As summarized in a recent thread on debian-science and debian-legal [4],
I am trying to push in the direction of solution (A), but I need help
in persuading Open CASCADE S.A.S. to switch to the GNU LGPL v2.1:
once again, please help!

Hi Julien,
thanks for your kind reply.
On a second glance, it seems that, in OmniORB, the
LGPL-library/GPL-tools distinction is more clear-cut than I initially
thought.
So, yes, you are right: the OmniORB libraries SALOME links with really
seem to be licensed under the GNU LGPL v2 or later, posing no issues
with Open CASCADE.
It's strange that this was one of the multiple licensing issues I
originally reported against the previous salome package (in bug
#619662), but it wasn't detected as non-existent...
Anyway, I am sorry of reporting a non-issue: I am closing the bug
report.
I am happy to see that there's one package less affected by the Open
CASCADE GPL-incompatibility, even though the Open CASCADE
GPL-incompatibility itself remains unsolved, unfortunately...
