Histoire de KDE
Qt, l'outil graphique utilisé pour créer les applications KDE n'était pas à l'origine sous une licence logicielle entièrement libre du fait que Trolltech possédait aussi un bras commercial. Les principales conséquences de ceci étaient que les programmes propriétaires créés pour KDE avaient besoin d'une licence de Trolltech, les créateurs de Qt, et que beaucoup de mises à jour de Qt devaient passer par Trolltech. Comme les logiciels KDE sont des projets libres, le choix de l'utilisation de Qt a créé de la controverse chez les puristes du logiciel libre. Qt a été re-licencié sous la GPL et ces disputes sont devenues obsolètes, mais sont une partie importante de l'histoire de KDE.
Pourquoi les développeurs de KDE ont-il choisi Qt ?
- Qt est le meilleur outil graphique disponible sur les plateformes UNIX. Le succès d'un environnement de bureau dépend de manière critique sur la disponibilité de ses applications. L'utilisation de Qt a poussé le développement des applications, et ainsi KDE.
- Qt est disponible gratuitement pour tout le monde, y compris son code source, pour le développement et la distribution de logiciels libres.
- Nous encourageons activement les entreprises de logiciels commerciaux à développer des applications pour KDE. Ces entreprises ont besoin d'un outil et d'un support technique mûrs et de bonne qualité. Aucun des autres outils GPL n'aurait été capable d'atteindre ces besoins d'exigence.
- Créer une version LGPL de l'outil Qt qui aurait atteint la qualité de l'implémentation de Trolltech aurait pris du temps et a été jugé d'une priorité plus faible que la créaton d'un bureau utilisable, gratuit et libre dans un premier temps.
La Fondation KDE Free Qt
To tackle this problem, the KDE Free Qt Foundation was founded by the KDE project and Trolltech. This foundation ensured the continued availability of Qt as a free software development framework. Namely, should Trolltech no longer make Qt available for free software, the currently released version will be re-released under the BSD style license - a license similar in nature but less restrictive than the GPL or LGPL.
This decision to re-release would be moderated by a team of 2 members representing the KDE foundation (unaffiliated with Trolltech) and 2 members from Trolltech to vote. In case of a tie, the KDE vote will gain higher weighting.
The Harmony Project
Those who prioritised the release of an GPL licensed formed the Harmony project - a project to clone Qt under a GPL license. Rapid progress was made during its time and thus gave purists no excuse to reject KDE as a respectable and compliant desktop environment. However this project was depreciated as Trolltech made the decision to re-license Qt under the GPL.
