I'm building opencv library with cmake for mingw to be used with qt and i've been able to generate the makefilelist. But when i type mingw32-make at the command prompt i get error when it's 44% built. error says:

Cannot export _ZN12_GLOBAL__N_13R)p3aLLEv: symbol not found
Cannot export _ZN12_GLOBAL__N_17CmpType3allEv: symbol not found
collect2: Id returned 1 exit status
mingw32-make[2]: ***[bin/opencv_perf_core.exe] Error 1

Please check the following tutorial for guidance on compiling: OpenCV Tutorial opencv with mingw

The instructions are for compiling OpenCV-2.3.0, however there is no difference in the method for latest version as well.
