compiling OpenCV(with Qt) for ARM

Hello,

I'm using
Ubuntu 12.10 on host
CMake 2.8.9
Using Qt 4.8.3
codesourcery: arm-2010.09-50-arm-none-linux-gnueabi

and I want to compile(on host) OpenCV (with Qt falg) for my Pandaboard (Ubuntu 12.04).

I wrote a Qt appliction using OpenCV => works as estimated.

CMake shows no errors after building/compiling but after "make" i got following error:
