I have compiled openCV 3.3.1 with static (BUILD_SHARED_LIBS off in cmake). Compile and install done successfully. Using this I compiled the following program. But it causes compilation errors, one line of which I have copied here (there are about 50 errors of similar kind). Request help. Thanks in advance.

main()

{

Mat img = Mat::zeros(300, 300,CV_8UC3);

imshow("output", img);

cout <<"hello world" << endl;

}

libopencv_highgui331.a(window_w32.cpp.obj):window_w32.cpp:(.text$_ZL15icvRemoveWindowP8CvWindow+0x114)||undefined reference to `__imp_SelectObject'

with static linking, the order of libraries matters. e.g. anything, that depends on core has to go before that.

also, you now have to link against all needed 3rd party and system libs now.

last time i tried, it looked like this:

g++ my.cpp -I. -Ic:\p\opencv\build -Ic:\p\opencv\build\install\include -Lc:\p\opencv\build\install\x64\mingw\staticlib -lopencv_optflow340 -lopencv_bioinspired340 -lopencv_tracking340 -lopencv_plot340 -lopencv_datasets340 -lopencv_dnn340 -lopencv_face340 -lopencv_xfeatures2d340 -lopencv_features2d340 -lopencv_calib3d340 -lopencv_flann340 -lopencv_objdetect340 -lopencv_ml340 -lopencv_photo340 -lopencv_video340 -lopencv_videoio340 -lopencv_highgui340 -lopencv_imgcodecs340 -lopencv_ximgproc340 -lopencv_imgproc340 -lopencv_core340  -llibprotobuf -lkernel32 -lgdi32 -lwinspool -lshell32 -lole32 -loleaut32 -luuid -lcomdlg32 -ladvapi32 -lvfw32 -llibpng -llibjpeg -lopengl32 -lglu32 -luser32 -lz -lgcov -O3 -o my.cpp
