Need help linking static OpenCV libraries in Qt Creator on Windows

Question

I have no problem linking the dynamic opencv libraries, but I want to use static libraries instead, so I rebuilt OpenCV 2.3 with the "build shared libraries" option unchecked. I put the following on 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 I had before when I was using the dynamic libraries, except the .a files actually ended in .dll .a, and I put the dll's (not the dll.a files) in the qt program's output directory (so the program could find them and run). Now the whole point is that I don't need those dlls, so they're no longer in my program's output directory (actually they didn't build with OpenCV). But I get these errors when I try to build my program:

I am using MinGW. Compiling the project with the same toolchain used to build opencv. Worked with dynamic libs, as mentioned above. Does not work with static libs.

It seems you're missing Jasper dependency. OpenCV on Windows uses pre-built libjasper library (lib/libjasper*), try adding them to LIBS

For the 'undefined reference to AVIStreamRelease@4'error, try linking against vfw32.lib or MSVFW32.dll
