Qt goes LGPL

2009-01-14 07:59 UTC by Quim Gil

Nokia has announced that Qt will be licensed under the terms of the LGPL version 2.1 with the upcoming Qt 4.5 release, in addition to the current GPL and commercial licenses. In the same move the Qt source code repository will be open and welcoming direct contributions, not requesting copyright assignment anymore. The new licensing is expected to increase adoption of Qt across all the supported platforms including Linux, Windows, Mac and S60.

LGPL is a very suitable license for Maemo application developers:

  • The introduction of the LGPL license provides the same permissive model for open and proprietary application development the current GTK+/Hildon GUI toolkit offers.
  • The Qt developer tools are also getting the same license scheme, which means that they will be free of charge for professional developers as long as they follow the LGPL terms in their applications.

Also, the Qt open development model and infrastructure will become the main reference for improving the Open Source practices in Maemo.

Qt support is offered at a community level currently in Maemo 4.1. The support will be continued and improved in Maemo 5 and it will become officially supported in the following release, codenamed Harmattan.
