There was a change of OCCT licence for version 6.7.0. It's LGPL + additional clause.
The full text is here:
https://fedoraproject.org/wiki/Licensing/Open_CASCADE_Technology_Public_L... The
additional clause:
Open CASCADE Exception (version 1.0) to GNU LGPL version 2.1.
The object code (i.e. not a source) form of a "work that uses the Library" can
incorporate material from a header file that is part of the Library. As a special
exception to the GNU Lesser General Public License version 2.1, you may distribute such
object code incorporating material from header files provided with the Open CASCADE
Technology libraries (including code of CDL generic classes) under terms of your choice,
provided that you give prominent notice in supporting documentation to this code that it
makes use of or is based on facilities provided by the Open CASCADE Technology software.
Is it a show stopper for fedora?
