    @SMF-Qt Ok thanks for the suggestions I now have a working X86_64 emulator and an X86_64 apk build that deploys to the emulated phone.

    @Dream_Helium said in Using Qt Program as a Module, but constantly get critical message: using GModule to load a Qt module just that thought scares me! Which Qt module are you loading and why with GModule? What is the expected result? g_main_context_pop_thread_default: assertion 'stack != NULL' failed As rightfully said: That error message comes from glib, not from Qt. Maybe consult the gtk forum.
