Recently, users of Bogdan Vatra’s Qt port for Android have started to discuss about various legal implications of using the code provided.
Konrad Rosenbaum from silmor has now posted the following to the official Qt-on-Android mailing list:
I just checked out n0.34 – the original Qt sources inside Necessitas are under the exact same license as the unmodified Qt itself: LGPL 2.1, GPL 3.0, LGPL- Exception 1.1 (you chose whatever fits best for you or you switch to the commercial license)
Most of the added sources are public domain (i.e. no strings attached). The Android platform plugin and the special qt_main for Android are under 3-clause BSD. The latter is the most limiting factor.
Meaning:
* Necessitas is free of charge
* Necessitas itself is Open Source
* your software can be commercial if you like (you must stop the users from
updating the Qt libs – just keep the default using Ministro as library
provider and you’ll be fine)
* your software can be under almost any Open Source license:
– LGPL 3.0 and GPL 3.0 are ok
– putting it under BSD is also ok
– I’m not entirely certain whether GPL 2.0 and LGPL 2.1 are ok, there might
be some interference from the 3rd clause of the BSD license (I’m also not
sure whether this is intended)
– I’m unfamiliar with the details of other licenses (Mozilla, Apache,
Artistic, etc.), so I can’t tell you for each one with certainty
Not more to add here…
