Is it possible to develop and sell a proprietary mobile application in Qt under a free license?

Question

Mobile development

I read that the Qt framework libraries are licensed under the LGPL. Is it possible to develop a commercial proprietary application on mobile devices (Android and iOS) under a free Qt license in this case? Or are only certain parts of the framework licensed under the LGPL?

Answer 1

Yes, you can, and you can sell. But:
1) Qt must be dynamically linked to your application. Qt must not be modified, or you must include patches/object files.
2) Qt can theoretically be linked statically, but then you definitely need to attach the object files of your program.
