1.protobuf 如果已经安装过protobuf时，make时会发生错误，解决方法是已经安装的protobuf的头文件包含的目录临时改名 2.jpeg2000 链接opencv_perf_imgproc.exe时发成错误，解决方法是cmake-gui成功完成后，在cvconfig.h文件中增加 #define OPJ_STATIC 1
然后编译应用程序时需要追加 -lopenjp2
make -j8 就OK啦
opencv从3.4版本没有.pc文件文件 自己写了 opencv440.pc 供参考 ---------------------------------------------------------------------- # Package Information for pkg-config Name: OpenCV Description: Open Source Computer Vision Library Version: 4.4.0 Libs: -L/usr/opt/opencv-4.4.0/x64/mingw/staticlib -lopencv_world440 Libs.private: -L/usr/opt/opencv-4.4.0/x64/mingw/staticlib -llibjpeg -llibpng -llibtiff -lIlmImf -L/usr/local/lib -lwebp -lvfw32 -lwinmm -lcomctl32 -lgdi32 -lole32 -lsetupapi -lws2_32 -lstdc++ -lglu32 -lopengl32 -lzlib -lopenjp2 Cflags: -I/usr/opt/opencv-4.4.0/include/opencv -I/usr/opt/opencv-4.4.0/include ----------------------------------------------------------------------
测试是否编译成功
#include <opencv2/opencv.hpp> #include <iostream> using namespace cv; using namespace std; int main(int argc, char** argv) { Mat image(600, 800, CV_8UC3, Scalar(100, 250, 30)); String windowName = "Window with Blank Image"; namedWindow(windowName); imshow(windowName, image); waitKey(0); destroyWindow(windowName); return 0; }
编译链接
version=opencv version=opencv220 version=opencv2413 version=opencv300 version=opencv3411 version=opencv440 OCV_CXXFLAGS=`pkg-config --cflags --static $version` OCV_LIBS=`pkg-config --libs --static $version` OCV_LIBS=${OCV_LIBS}" -lcomdlg32 -lgdi32 -lcomctl32" echo OCV_CXXFLAGS = $OCV_CXXFLAGS echo OCV_LIBS = $OCV_LIBS echo CC;g++ -c opencv.cc $OCV_CXXFLAGS && echo LINK;g++ -g opencv.o -o opencv-g $OCV_LIBS -static cp opencv-g.exe opencv.exe && echo STRIP; strip opencv.exe
运行exe文件，验证编译的库文件是否正常；
最后不要忘记改过名的 local/include/google/protobuf ，改回原来的名字
