Not sure about Qt 5.10, but Qt 5.12 have support for arm64-v8a target. You will need to build two APK files, one for armeabi-v7a, and one for arm64-v8a, with different versionCode values in manifest, and then just publish both in the same release.

@koahnig So there's config and rebuild needed. Thank you very much for the helpful reply.

You can try to add your static libraries like this: LIBS += PATH_TO_LIB_DIR/libLIBNAME.lib

@SGaist Oh, I see where to do that. Thanks. I think that last part makes for a solution.

@Karen-Morrissey I think because when you did ./configure to look for needed libraries, it first found those in /usr/lib64. Why not to force the configure to use those for 32bit by adding -L /path/to/lib/32bit -lpthread -lm -lc to your configure command

Hi, If you want to build KDSOAP for 32bit then just use a 32bit Qt build. You'll avoid all these troubles

@sierdzio said: Thanks a lot for the clarification.
