Hi, We have now clarified the license agreement to allow use of independent open-source items in conjunction with commercially license Qt.
The updated agreement (version 4.2.3) states: "Permitted Software" shall mean any (i) open source software (excluding Open Source Qt) that is a) generally available for public in source code form without additional cost under any of the licenses approved by Open Source Initiative as listed on https://opensource.org/licenses; and (b) is in no way, directly or indirectly, developed by or for or otherwise related to or in the interest of the Licensee or its Affiliates, or (ii) software The Qt Company has made available via its Qt Marketplace online distribution channel. Updated agreement can be found from https://www.qt.io/terms-conditions as well as from the Qt online installer. This clarification should clear the usage of independent open-source tools and libraries containing or developed with Qt. Mixing of open-source Qt framework and tools with commercially licensed Qt remains forbidden, just like before.

Then you should find a solution. This puts customers / developers / users in the situation that they depend on the goodwill of a for-profit corporation. However, there is no good will in a profit-making business. It must be perfectly clear that development projects are not affected by the fundamental use of third-party Qt-based applications. I probably will not use Qt for new projects and I cannot recommend it (but I have to add that this decision is also driven by the fact that the technical priorities in the Qt project have not been in line with my priorities for a few years) . -- Best Regards, Bernhard Lindner _______________________________________________ Interest mailing list Interest@qt-project.org https://lists.qt-project.org/listinfo/interest _______________________________________________ Interest mailing list Interest@qt-project.org https://lists.qt-project.org/listinfo/interest
