QwtPlot3D project Compilation with Code Blocks Fails

[<luk...@o2...>]

Hello, I am struggling with following problem:
I've built qwtplot3d with mingw32 (v.5.1.4) on my Windoze XP sp2. I am trying to run some examples project, but my IDE (CodeBlocks v. 8.02) returns the following compilation report:
/*******************************************************************************************/

I've created the moc file with qt's meta object tool, and added the output .cpp file to the project. 
The project is linked against the libs created during the qwtplot3d build process. 
Can Anybody help me with this issue?
Best,
Lukasz
