[Qt-creator] Cross-compiling for ARM with qt creator - SOLVED -

[Uwe Fechner]

Hello,

I just wanted to give you the feedback, that I solved this issue by 
using the tool-chain from CodeSourcery.
I documented, what I did here:

and here:

Thank you for help!
It is fun, to develop embedded Software with QT Creator.

Uwe Fechner, TU Delft
