Ah, this is interesting. The amount of packages will probably be larger in the current sid, but it should not be more than 20 packages. Plus there are packages which are using QT_OPENGL_ES macro for conditional compilation (as I mentioned in my previous mail), but there are also not many of them: gammaray goldendict gst-plugins-good1.0 kamoso krita leocad openclonk phonon-backend-gstreamer qtav qt-gstreamer qtwebkit-opensource-src qtwayland-opensource-src qtcharts-opensource-src > So perhaps someone in this thread is willing to put in this effort to > maintain 6 source packages, in order to avoid having to make a choice > between GL and GLES on arm64. I wonder if these can be new binaries in existing source packages, instead of separate source packages. Otherwise we will have too much code duplication, and also wasted time: for example, in qtbase-opensource-src, only src/gui needs to be built twice, and there is no need to built other submodules twice. We already have an example of double build inside the same source: on i386, src/corelib is built twice, with and without sse2 support. In any case, this task looks manageable. Maybe if I have time someday I will take care of it, but in the meantime volunteers are welcome. -- Dmitry Shachnev
