Mac系统下vscode调试opencv环境搭建

安装opencv

brew install opencv

opencv示例代码 test.cpp

#include 
#include 
 
using namespace std;
using namespace cv;
 
int main()
{
    Mat srcImage = imread("../1.png");
    imshow("Display Image window",srcImage);
    waitKey(0);
    return 0;
}

vscode调试

vscode调试c++程序主要有三个文件：.vscode文件夹下的c_cpp_properties.json，launch.json，tasks.json

• c_cpp_properties.json最主要是指明 includePath，将opencv的路径放进去。
  

{
    "configurations": [
        {
            "name": "Mac",
            "includePath": [
                "${workspaceFolder}/**",
                "/usr/local/include/opencv4",
                "/usr/local/Cellar/opencv/4.6.0/include/opencv4",
                "/usr/local/Cellar/opencv/4.6.0/lib/**"
            ],
            "defines": [],
            "macFrameworkPath": [
                //"/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks"
            ],
            "compilerPath": "/usr/bin/g++",
            "cStandard": "c11",
            "cppStandard": "c++11",
            "intelliSenseMode": "macos-clang-x64"
        }
    ],
    "version": 4
}

• launch.json就用默认生成的就可以。

{
    "configurations": [
        {
            "name": "C/C++: g++ 生成和调试活动文件",
            "type": "cppdbg",
            "request": "launch",
            "program": "${fileDirname}/${fileBasenameNoExtension}",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${fileDirname}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "lldb",
            "preLaunchTask": "C/C++: g++ 生成活动文件"
        }
    ],
    "version": "2.0.0"
}

• task.json主要是在args里声明c++的版本，以及pkg-config和要动态链接的库。
  

{
    "tasks": [
        {
            "type": "cppbuild",
            "label": "C/C++: g++ 生成活动文件",
            "command": "/usr/bin/g++",
            "args": [
                "-fdiagnostics-color=always",
                "-std=c++11",//使用C++11
				"-stdlib=libc++",
                "-g",
                "${file}",
                "-o",
                "${fileDirname}/${fileBasenameNoExtension}",
                "`pkg-config",
				"--libs",
				"--cflags",
				"opencv4`"
            ],
            "options": {
                "cwd": "${fileDirname}"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": "build",
            "detail": "调试器生成的任务。"
        },
    ],
    "version": "2.0.0"
}
