windows平台使用vscode 配置opencv

window下使用vscode 配置opencv环境

注释：工程位置不能有中文
1、安装vscode，网上搜索
2、下载mingw64 ,然后解压添加环境变量
参考：C:\MinGW\bin
3、下载opencv编译过文件，一般我们可以在csdn上找文件
参考：F:\opencv\build\x64\MinGw\install ，这是我下载的opencv文件夹，我们只需要install文件夹，然后拷贝到F:
添加环境变量：F:\install\x64\mingw\bin
4、下一步，打开vscode，创建一个main.cpp 文件

#include 
#include 

using namespace cv;
using namespace std;

int main()
{
    VideoCapture cap(0);
    Mat img;
    cout<<"jsy"<<endl;

    while (1)
    {
        cap >> img;
        if (img.empty())
            break;
        namedWindow("img", WINDOW_NORMAL);
        imshow("img", img);
        if (27 == waitKey(20))
            break;
    }

    return 0;
}

点击 “运行”“启动调试”
会生成一个文件夹.vscode
然后配置里面三个文件

{
    "configurations": [
        {
            "name": "Win32",
            "includePath": [
                "${workspaceFolder}/**",
                "F:/install/include",
                "F:/install/include/opencv2"//添加两个路径，保障代码不会报错
            ],
            "defines": [
                "_DEBUG",
                "UNICODE",
                "_UNICODE"
            ],
            "compilerPath": "F:/MinGW/bin/g++.exe",
            "cStandard": "c17",
            "cppStandard": "c++17",
            "intelliSenseMode": "windows-gcc-x64"
        }
    ],
    "version": 4

{
    // 使用 IntelliSense 了解相关属性。 
    // 悬停以查看现有属性的描述。
    // 欲了解更多信息，请访问: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "g++.exe - 生成和调试活动文件",
            "type": "cppdbg",
            "request": "launch",
            "program": "${fileDirname}\\${fileBasenameNoExtension}.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",//这里修改过
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "miDebuggerPath": "F:\\MinGW\\bin\\gdb.exe",
            "setupCommands": [
                {
                    "description": "为 gdb 启用整齐打印",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ],
            "preLaunchTask": "C/C++: g++.exe 生成活动文件"
        }
    ]
}

一般点击生成时，gdb.exe位置正确，就不用修改

{
    "tasks": [
        {
            "type": "cppbuild",
            "label": "C/C++: g++.exe 生成活动文件",
            "command": "F:\\MinGW\\bin\\g++.exe",
            "args": [
                "-fdiagnostics-color=always",
                "-g",
                "${file}",
                "-o",
                "${fileDirname}\\${fileBasenameNoExtension}.exe",
                "F:/install/x64/mingw/bin/libopencv_world452.dll",//添加依赖库，由于cmake编译时，选择生成了word,所以只需要一个静态库。
                "-I","F:/install/include",//添加头文件
                "-I","F:/install/include/opencv2"

            ],
            "options": {
                "cwd": "F:\\MinGW\\bin" //这里需要设置
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "detail": "调试器生成的任务。"
        }
    ],
    "version": "2.0.0"
}

Ctrl + shift + p 进入命令面板

cmakeconfig 产生build文件夹
c/c++ edit编辑配置 产生 c_cpp_propro …这个文件，配置c/c++编辑环境，
