First time build OpenCV 2.4.7 with MinGW64 on Win7. I have a working MinGW64 build of Qt 4.8 installed, Cmake found it, system PATH finds its dlls. BUT opencv test pgms crash at launch with "procedure entry point _Z17qt_message_output9QtMsgTypePKc not found in QtCore4.dll". Even though dependency walker reports that entry point is present in the QtCore4.dll that would be loaded.

Can anybody explain this, or provide a workaround?

Hi, while building OpenCV 2.4.7 cmake was asking explicit for Qt5 DLL's. That's why I used the Qt5.1.1 the latest version while building OpenCV 2.4.7. Don't know if this going to be satisfying for you. cheers
