linux下如何在vscode中配置opencv环境

这里使用的是C++作为编程语言，当然默认读者已经配置好了C++的编程环境 首先使用 pkg-config --modversion opencv命令查看版本，确保成功安装了o p e n c v opencv o p e n c v，我的版本是 4.5.4 #include #include int main(){ cv::Mat image = cv::imread("tiger.jpg"); cv::namedWindow("My Image"); cv::imshow("My Image", image); cv::waitKey(5000); return 1; }如果现在新建一个 cpp文件，输入上面的内容（这个tiger.jpg应该是当前目录下的一张图片）看到的应该是下面的画面 
这时候，我们打开 c_cpp_properties.json文件，在 includePath中加入一行 "/usr/local/include/**"，改成下面这样 { "configurations": [ { "name": "Linux", "includePath": [ "${workspaceFolder}/**", "/usr/local/include/**" ], "defines": [], "compilerPath": "/usr/bin/cpp", "cStandard": "gnu17", "cppStandard": "c++17", "intelliSenseMode": "linux-gcc-x64" } ], "version": 4 }就在那时，我们发现红色的波浪线消失了。 [En]That’s when we found that the red wavy line had disappeared. 再次运行，报错如下这时候，我们打开 tasks.json文件，在上面的 args中加入
"-I", "/usr/local/include",
"-I", "/usr/local/include/opencv4",
"-L", "/usr/local/lib",
"-l", "opencv_core",
"-l", "opencv_imgproc",
"-l", "opencv_imgcodecs",
"-l", "opencv_video",
"-l", "opencv_ml",
"-l", "opencv_highgui",
"-l", "opencv_objdetect",
"-l", "opencv_flann",
"-l", "opencv_imgcodecs",
"-l", "opencv_photo",
"-l", "opencv_videoio"
这个文件变成了下面这样 { "version": "2.0.0", "tasks": [ { "label": "build", "type": "shell", "command": "g++", "args": [ "-g", "${file}", "-std=c++11", "-o", "${fileBasenameNoExtension}.out", "-I", "/usr/local/include", "-I", "/usr/local/include/opencv4", "-L", "/usr/local/lib", "-l", "opencv_core", "-l", "opencv_imgproc", "-l", "opencv_imgcodecs", "-l", "opencv_video", "-l", "opencv_ml", "-l", "opencv_highgui", "-l", "opencv_objdetect", "-l", "opencv_flann", "-l", "opencv_imgcodecs", "-l", "opencv_photo", "-l", "opencv_videoio" ] }, { "type": "cppbuild", "label": "C/C++: cpp 生成活动文件", "command": "/usr/bin/cpp", "args": [ "-fdiagnostics-color=always", "-g", "${file}", "-o", "${fileDirname}/${fileBasenameNoExtension}" ], "options": { "cwd": "${fileDirname}" }, "problemMatcher": [ "$gcc" ], "group": "build", "detail": "编译器: /usr/bin/cpp" } ] }然后返回并再次运行，但仍报告错误。 [En]Then come back and run it again, and still report an error. 这是一个新的问题，按照指示，我们i n s t a l l l i b g t k 2.0 − d e v a n d p k g − c o n f i g install\ libgtk2.0-dev\ and\ pkg-config i n s t a l l l i b g t k 2 .0 −d e v a n d p k g −c o n f i g，使用 sudo apt-get install命令安装即可，之后要重新编译一遍o p e n c v opencv o p e n c v，可参考https://blog.csdn.net/Lin_QC/article/details/104431330然后我们再次运行这个程序，它是成功的，可能是这样的，这是我当地的一张照片。
[En]
And then we run the program again and it’s a success, probably like this, this is a picture of my local. 那么现在就配置好opencv了
