Qt Raspberry Pi2 - Linux Arch

Hey
i´ve installed qtcreator,the qt-packages,clang and gcc on my linux arch.
First of all qt-creator doesn´t auto detect my compilers(which are located e.g gcc: /usr/bin/gcc). So i added them and selected them in my default-build-kit. When i try to build i only get them progress bar that gets red, but no errors. I haven´t set any "Platform codegen flags" or "Platform linker flags". I´m not good working with linux so maybe someone finds my error.

Edit:
The gcc-compiler sets the ABI to : arm-linux-generic-elf-32bit
Qt-Version 5.5.1 for Embedded Linux


Ciao

Do you run QtCreator on the device?
Or is /usr/bin/gcc the GCC for the host machine?

Cheers,

QtCreator runs on the Pi.
