I use QT creator (QT 5.5.1)+MinGW and OpenCV 2.4.11 binaries I try to link opencv libraries in qt creator by following code:

LIBS += -L$$PWD/../../OpenCV/opencv/build/x86/vc12/bin/ -lopencv_core2411 -lopencv_highgui2411 -lopencv_objdetect2411 -lopencv_imgproc2411

All OK if i use simple C funcitons, like cvLoadImageM("img.jpg"), but when i try to use C++ version of this function imread("img.jpg") i get error that it is undefined.

It seems that there is some linker error, but i don't understand how to fix it... Can you help me ?

you just cannot use the vc12 prebuild libs with mingw, but you will have to build the opencv libs wirh mingw (and cmake) before doing anything else.

Thank you for your reply. While I was not able to rebuild opencv with mingw
