2 配置工具链
安装过程不说了教程到处都是。编译的话使用CMAKE配置如下 上面两个路径分别是
源码目录编译生成的文件放置的位置这里放在源码目录下的build目录中
然后点下面那个Configure配置工具链也就是选编译器的bin目录这个看你自己用的啥编译器我是安装的GNU工具链还有就是选make工具我选的是minGW Make Tool看你自己用的什么。配置的时候它会自己下载第三方包可能比较慢。 之后就点Gernate生成makefiles很快。
3 开始编译
生成完了之后就可以进到源码目录编译了我这里使用mingw32-make.exe 作为make工具
编译过程会有进度提示:

[100%] Built target opencv_model_diagnostics到100%就编译完了 build/bin目录下会有一堆动态库 写一个测试demo这里用官方提供的
#include stdio.h
#include opencv2/opencv.hppusing namespace cv;int main(int argc, char** argv )
{printf(usage: DisplayImage.out Image_Path\n);if ( argc ! 2 ){printf(usage: DisplayImage.out Image_Path\n);return -1;}Mat image;image imread( argv[1], IMREAD_COLOR );if ( !image.data ){printf(No image data \n);return -1;}namedWindow(Display Image, WINDOW_AUTOSIZE );imshow(Display Image, image);waitKey(0);waitKey(0);waitKey(0);waitKey(0);waitKey(0);return 0;
}用下面这个命令编译
g ./showiamge.cpp
-I L:\SoftWares\opencv\opencv\build\include
-L L:/SoftWares/opencv-4.10.0/build/lib
-lopencv_calib3d4100 -lopencv_core4100 -lopencv_dnn4100 -lopencv_features2d4100 -lopencv_flann4100 -lopencv_gapi4100 -lopencv_highgui4100 -lopencv_imgcodecs4100 -lopencv_imgproc4100 -lopencv_ml4100 -lopencv_objdetect4100 -lopencv_photo4100 -lopencv_stitching4100 -lopencv_ts4100 -lopencv_video4100 -lopencv_videoio4100注意头文件目录要在安装目录里去找里面有各个模块的头文件
-I L:\SoftWares\opencv\opencv\build\include 安装目录的\build\include:
源码编译目录下的include\只有一个头文件
生成的a.exe就是编译出来的可执行文件这时候需要把动态库放到同一个目录下 然后就可以执行了完事。
