Hi, I'm currently trying to link our app on iOS dynamically against Qt. From the technical standpoint everything seems to be working, but I have a problem with the licensing.
I would like to conform to the LGPL license, meaning that I want to link against all Qt parts dynamically, but I have to link the iOS platformplugin statically because qioseventdispatcher.mm defines a custom program entry point (and does some voodoo with setjmp/longjmp). I currently also have to link statically against some other modules (Qt5GraphicsSupport, Qt5FontDatabaseSupport, Qt5ClipboardSupport), but the platform plugin is the most crucial part. qioseventdispatcher.mm and every other file in the platformplugin is LGPL licensed. From my understanding I would violate the LGPL license if I would try to distribute the app in this form, because a user could not easily swap the provided Qt-library with his own. The app itself is under the non-compatible EUPL. Is there a way to build the iOS platformplugin dynamically? There has been some interest in building shared libs for iOS in the past, is there maybe already a strategy to be LGPL compliant? On Windows there exists qtbase/src/winmain, where the program entry point is isolated into BSD-licensed source files. Maybe something similiar could be possible? best regards, Jens Trillmann _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
