    Where can I find a list of LGPL Qt modules for a specific release of Qt ?

      @ambershark said in Qt Commercial License Terms, Independent Developers:

      Since you can now link dynamically on both iOS and android

      Ah, right, is that what I was thinking I recalled when I wrote

      I think it used to require static linking maybe, but not now

      ? Have they made it so you can now but didn't used to be able to? OOI, is that a change at the Android side or the Qt side to make it possible?

      @JonB Pretty sure android always supported dynamic linking, although I could be wrong here, I'm not really a mobile developer. I've done one back end library on mobile and that was it.

      It was iOS that used to be static only and change to allow dynamic linking recently (like last year or 2).

        I am an independent game author. If I use LGPL, develop a library that uses QML and dynamically links QT, and then publish it to steam, do I need to pay QT or open source?

          No, as long as you can fulfill LGPL3 you do not need commercial license and do not have to open your source code.
          LGPL3 requires you to provide users the possibility to replace Qt libraries with their own versions. This usually requires you to provide object files (.o), so users can relink. And it is not possible when using static Qt libraries!

          Keep in mind people here (me included) are not lawyers!

            No QT official came out to clarify? This matter is important

              @Cheng-shi-hua This forum is for Qt users and not "Qt officials". If you want an answer from Qt officials then pleas ask Qt Company.

                This is the case, thank you very much. Since it is a community, you can advertise here when I develop a game :)
