The erros 'does not support ARM mode' is mentioned in my first post here and managed to get around it with turning off optimization (I did not compile anything big though, only simple QT app that I managed to find source for, but it did full compile, can you check if you can compile Qrencode successfully? I might have used this one, not sure: http://repository.maemo.org/extras/p...1maemo1.tar.gz, if it fails then the setup needs tweaking, if it goes through, then my testing was insufficient). Do you have CSSU thumb installed? This could be responsible for the thumb errors. Would probably be best to recompile qmake on device with the same set of qt libs (I remember had to have a mix of 4.7.0 and 4.7.4, maybe this is causing it and the app I chose for testing was just a lucky hit?).
