I think it is a problem wiht my MinGW configuration, but I really don't know what.
I downloaded and installed the qt-win-opensource-4.6.2-mingw.exe...
I write my QT - App on Kubunutu with eclipse, but I need the application also for windows that's the reason why I compile and link it on windows. I have no IDE on the windows machine. I only use MinGW and QT Command Prompt.


So many thanks for your help. I hope I find a solution.
If I get one, I will post it here.
