[question] Orion/Qt Licensing #191

Closed ahjolinna closed 7 years ago

ahjolinna commented 7 years ago

I'm little bit confused as which license orion should be using, as Orion currently is using basic GPL v3 and it seem the opensource Qt projects should be using LGPL v3? ....thought some stuff do u use other : http://doc.qt.io/qt-5/licenses-used-in-qt.html

source: http://doc.qt.io/qt-5/licensing.html and https://www.qt.io/licensing/ and https://www.qt.io/faq/#_Toc_3 and http://doc.qt.io/qt-5/opensourcelicense.html

There's no clash. LGPL3 is compatible to be used in GPL3 licensed source

ahjolinna commented 7 years ago

as long as there is no clash then its fine, my confusion was more to do with that what license does Qt5 require for the opensource devs to use with their created software. it seems KDE uses (L)GPLv2, which I personally prefer over v3 ...LGPLv 2.1 is also fine (what for example MPV uses now)...

I never liked the newer "basic" GPLv3, mostly for the same reasons as Linus T. but if v3 is the license you like for Orion, I think I will survive :D

@ahjolinna LGPLv3 only requires you to provide the application code in a form suitable for relinking, which could be just object code and not source, with a license that allows relinking. https://www.gnu.org/licenses/lgpl-3.0.en.html#section4. This is what the Qt licensing docs presumably mean when they say "provided you can comply with the terms and conditions of the GNU LGPL version 3".
