[linux-team] KDE suite



resume :

Les sources de KDE sont sous GPL
les binaires de KDE linke avec QT derivent des sources de KDE
=> les binaires de KDE sont sous GPL aussi
=> les sources de ces binaires (y compris QT) peuvent etre modifiees
Or QT ne peut pas etre modifie


 extrait de : http://www.linuxtoday.com/stories/158.html :

1) Troll Tech's Qt library is distributed under a licence[5] that
includes this condition:

You may copy this version of the Qt Free Edition provided that the
entire archive is distributed unchanged and as a whole,
including this notice.

2) The KDE code is licensed under the GNU GPL v2[6]

3) Currently, KDE must be linked against Qt in order to produce usable
binaries.

Clause 2.b. of the GPL reads:

     You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the
     Program or any part thereof, to be licensed as a whole at no charge
to all third parties under the terms of this License.

The corollary of this is that if you link the GPLed KDE code against
Troll Tech's Qt library, and distribute it, you must
distribute it under the GPL.

However, the GPL insists that you grant the right to modify the complete
source of a program distributed under its terms,
which is clearly in conflict with Qt's licence conditions.

Clause 7 of the GPL reads:

     7. If ... for any other reason ... conditions are imposed on you
... that contradict the conditions of this License, they do
     not excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your
     obligations under this License and any other pertinent obligations,
then as a consequence you may not distribute the
     Program at all.

So, we have been denied the right to ``distribute the Program at all''.
