I have no problem linking opencv dynamic libraries, but instead I want to use static libraries, so I restored OpenCV 2.3 with the option "collect shared libraries". I put the following in my .pro file
LIBS += "C:\Program Files\openCV_static\opencv\build\install\lib\libopencv_calib3d231.a" \ "C:\Program Files\openCV_static\opencv\build\install\lib\libopencv_contrib231.a" \ "C:\Program Files\openCV_static\opencv\build\install\lib\libopencv_core231.a" \ "C:\Program Files\openCV_static\opencv\build\install\lib\libopencv_features2d231.a" \ "C:\Program Files\openCV_static\opencv\build\install\lib\libopencv_flann231.a" \ "C:\Program Files\openCV_static\opencv\build\install\lib\libopencv_gpu231.a" \ "C:\Program Files\openCV_static\opencv\build\install\lib\libopencv_highgui231.a" \ "C:\Program Files\openCV_static\opencv\build\install\lib\libopencv_imgproc231.a" \ "C:\Program Files\openCV_static\opencv\build\install\lib\libopencv_legacy231.a" \ "C:\Program Files\openCV_static\opencv\build\install\lib\libopencv_ml231.a" \ "C:\Program Files\openCV_static\opencv\build\install\lib\libopencv_objdetect231.a" \ "C:\Program Files\openCV_static\opencv\build\install\lib\libopencv_ts231.a" \ "C:\Program Files\openCV_static\opencv\build\install\lib\libopencv_video231.a" INCLUDEPATH += "C:\Program Files\openCV_static\opencv\build\install\include" INCLUDEPATH += "C:\Program Files\openCV_static\opencv\build\install\include\opencv"
This is very similar to what it used to be when I used dynamic libraries, except that the .a files actually ended .dll.a and I put the dll (and not the dll.a files) in the qt program (so the program could find and run them). Now the thing is that I do not need these DLLs, so they are no longer in my output directory of the program (in fact, they were not built with OpenCV). But I get these errors when I try to create my program:

I am using MinGW. Compiling a project using the same toolchain as creating opencv. Worked with dynamic libraries, as mentioned above. It does not work with static libraries.
