Description Andreas K. Huettel 2013-09-05 19:14:40 UTC

libkface incorporates code from OpenTLD, licensed under GPL-3 (*), while libkface itself is licensed GPL-2. These two licenses are incompatible, see 
http://www.gnu.org/licenses/gpl-faq.html#AllCompatibility
which means that distribution of the combined work is not permitted.

Comment 1 Marcel Wiesweg 2013-09-05 20:09:39 UTC

libkface is GPLv2 or later (I hope there are not parts which are GPLv2 only) so the combined work would effectively be GPLv3.
This still violates the KDE license policy. We currently do not use OpenTLD based recognition, so we can cut the connection.

Comment 2 caulier.gilles 2014-06-12 06:01:55 UTC

Git commit 8581dd6c685f103a874cd1fe92747f8da3a0323f by Gilles Caulier.
Committed on 12/06/2014 at 05:57.
Pushed by cgilles into branch 'master'.

Accordingly with Marcel Wiesweg comment #1 from bugs #324566, OpenTLD and CVBlobs libraries embeded in libkface can be dropped.
This code is not used anymore.
