本文详细介绍如何在Windows环境下使用VsCode配置C/C++及Opencv开发环境，无需安装MinGW，通过设置.vscode文件夹下的四个配置文件，实现代码智能感知、编译及调试。

VsCode配置C、C++ opencv环境/编写运行C、C++（Windows）

这个方法不用安装MinGW

1.配置基本文件

首先在文件夹下新建.vscode文件，然后往里面放四个文件，具体的代码如下

.vscode\c_cpp_properties.json

第7,8行换成自己的opencv配置环境

第十六行换成自己的visual studio Hostx86/x64/cl.exe 路径

{
    "configurations": [
        {
            "name": "Win32",
            "includePath": [
                "${workspaceFolder}/**",
                "D:/Program Files/opencv/build/include",
                "D:/Program Files/opencv/build/include/opencv2"
            ],
            "defines": [
                "_DEBUG",
                "UNICODE",
                "_UNICODE"
            ],
            "windowsSdkVersion": "10.0.17763.0",
            "compilerPath": "D:/Program Files/visual studio 2019/VC/Tools/MSVC/14.24.28314/bin/Hostx86/x64/cl.exe",
            "intelliSenseMode": "msvc-x64"
        }
    ],
    "version": 4
}

.vscode\c_cpp_properties.json

这里的"program": "${fileDirname}\\main.exe"可以自己指定生成的exe的位置和名称

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "cl.exe debug",
            "type": "cppvsdbg",
            "request": "launch",
            "program": "${fileDirname}\\main.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": true,
        },

        {
            "name": "cl.exe build and debug active file",
            "type": "cppvsdbg",
            "request": "launch",
            "program": "${fileDirname}\\main.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": true,
            "preLaunchTask": "cl.exe build active file"
        }
    ]
}

.vscode\settings.json

配置一些需要的头文件

{
    "files.associations": {
        "fstream": "cpp",
        "iostream": "cpp",
        "vector": "cpp",
        "cmath": "cpp",
        "xstring": "cpp",
        "array": "cpp",
        "deque": "cpp",
        "initializer_list": "cpp",
        "list": "cpp",
        "queue": "cpp",
        "type_traits": "cpp",
        "xhash": "cpp",
        "xtree": "cpp"
    },
    "python.pythonPath": "D:\\Anaconda3\\python.exe"
}

.vscode\tasks.json

同样这里的17-21行要换成自己的opencv地址

{

    "version": "2.0.0",
    "tasks": [
        {
            "type": "shell",
            "label": "cl.exe build active file",
            "command": "cl.exe",
            "args": [
                "/Zi",
                "/EHsc",
                "/Fe:",
                "${fileDirname}\\main.exe",
                "twosum.cpp",
                "/I",
                "D:/Program Files/opencv/build/include",
                "/I",
                "D:/Program Files/opencv/build/include/opencv2",
                "/link",
                "D:/Program Files/opencv/build/x64/vc15/lib/opencv_world410.lib"
            ],
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            }
        },
        {
            "type": "shell",
            "label": "cl.exe build active file",
            "command": "cl.exe",
            "args": [
                "/Zi",
                "/EHsc",
                "/Fe:",
                "${fileDirname}\\${fileBasenameNoExtension}.exe",
                "${file}"
            ],
            "problemMatcher": [
                "$msCompile"
            ],
            "group": "build"
        }
    ]
}
