1.Building opencv4:

cmake .. -DCMAKE_INSTALL_PREFIX=/home/wwd/software/opencv_4.1.0_build/ -DOPENCV_EXTRA_MODULES_PATH=/home/wwd/software/opencv_contrib-4.1.0/modules/ -DBUILD_SHARED_LIBS=OFF -DBUILD_opencv_world=ON

make -j 20

make install

2.After Building:

I copy all .a files in /home/wwd/software/opencv_4.1.0_build/lib64/opencv4/3rdparty to /home/wwd/software/opencv_4.1.0_build/lib64/ for convenience

3.Compiling my own app.cpp

g++ -static -o app app.cpp -I/home/wwd/software/boost_1.70.0_build/include -I/home/wwd/software/opencv_4.1.0_build/include/opencv4/ -L/home/wwd/software/boost_1.70.0_build/lib -L/home/wwd/software/opencv_4.1.0_build/lib64/ -lpthread -lboost_system -lboost_filesystem -lboost_program_options -lpthread -lboost_system -lboost_filesystem -lboost_program_options -lopencv_img_hash -littnotify -lopencv_world -llibwebp -lpng16 -llibjpeg-turbo -llibtiff -llibprotobuf -llibjasper -lade -lIlmImf -lquirc -lz -lippiw -lippicv

4.Generate many ld errors:

Some of this errors:

5.I think wrong order of linking static opencv libs lead to ld errors, so what is the order for linking static libs? Anybody can help?

See in https://stackoverflow.com/questions/4..., Someone said "-Wl,--start-group" g++ option may work... I will try it

Using OpenCV3 and pkg-config is a solution!
