VScode配置C/C++编译环境

1、下载MinGWX64.zip，解压后放到指定位置，如：C:Program Files

2、配置环境变量：C:Program Filesmingw64bin

3、在cmd窗口中输入：gcc -v ，出现以下内容表示配置成功

二、配置VScode

1、在磁盘上创建工作区，也就是创建文件夹并命名。本人已在E盘创建文件夹cppStudy

    2、创建.vscode文件夹

   3、在.vscode文件夹中创建3个json文件，分别命名为：launch.json    tasks.json 、c_cpp_properties.json

         3.1、launch.json内容如下：

{
    // 使用 IntelliSense 了解相关属性。 
    // 悬停以查看现有属性的描述。
    "version": "0.2.0",
    "configurations": [
        {
            "name": "g++.exe build and debug active file",
            "type": "cppdbg",
            "request": "launch",
            "program": "${fileDirname}\${fileBasenameNoExtension}.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": true,
            "MIMode": "gdb",
            "miDebuggerPath": "C:\Program Files\mingw64bin\gdb.exe",        
            "setupCommands": [
                {
                    "description": "为 gdb 启用整齐打印",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ],
            "preLaunchTask": "task g++"
        }
    ]
}

             3.2、tasks.json内容如下：

{
     "version": "2.0.0",
     "command": "g++",
     "args": [
            "-g",
            "${file}",
            "-o",
            "${fileBasenameNoExtension}.exe"
        ],
     "problemMatcher": {
        "owner": "cpp",
        "fileLocation": [
            "relative",
            "${workspaceRoot}"
        ],
        "pattern": {
            "regexp": "^(.*):(\d+):(\d+):\s+(warning|error):\s+(.*)$",
            "file": 1,
            "line": 2,
            "column": 3,
            "severity": 4,
            "message": 5
        }
    }
}

             3.3、c_cpp_properties.json内容如下：

{
    "configurations": [
        {
            "name": "Win32",
            "intelliSenseMode": "gcc-x64",
            "includePath": [
                "${workspaceFolder}",
                "C:/Program Files/mingw64/lib/gcc/x86_64-w64-mingw32/8.1.0/include/c++", 
                "C:/Program Files/mingw64/lib/gcc/x86_64-w64-mingw32/8.1.0/include/c++/x86_64-w64-mingw32", 
                "C:/Program Files/mingw64/lib/gcc/x86_64-w64-mingw32/8.1.0/include/c++/backward", 
                "C:/Program Files/mingw64/lib/gcc/x86_64-w64-mingw32/8.1.0/include", 
                "C:/Program Files/mingw64/include",
                "C:/Program Files/mingw64/lib/gcc/x86_64-w64-mingw32/8.1.0/include-fixed",
                "C:/Program Files/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/../../../../x86_64-w64-mingw32/include"
            ],
            "defines": [
                "_DEBUG",
                "UNICODE",
                "__GNUC__=7",
                "__cdecl=__attribute__((__cdecl__))"
            ],
            "compilerPath": "",
            "browse": {
                "path": [
                    "${workspaceFolder}",
                    "C:/Program Files/mingw64/lib/gcc/x86_64-w64-mingw32/8.1.0/include/c++", 
                    "C:/Program Files/mingw64/lib/gcc/x86_64-w64-mingw32/8.1.0/include/c++/x86_64-w64-mingw32",
                    "C:/Program Files/mingw64/lib/gcc/x86_64-w64-mingw32/8.1.0/include/c++/backward",
                    "C:/Program Files/mingw64/lib/gcc/x86_64-w64-mingw32/8.1.0/include",
                    "C:/Program Files/mingw64/include",
                    "C:/Program Files/mingw64/lib/gcc/x86_64-w64-mingw32/8.1.0/include-fixed",
                    "C:/Program Files/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/../../../../x86_64-w64-mingw32/include"
                ]
            },
            "cppStandard": "c++17",
            "cStandard": "c17"
        }
    ],
    "version": 4
}

三、测试环境：

   1、编写C语言程序

   2、编写C++程序

四、注意的问题

     1、关于配置文件：如果在VScode中新建文件夹保存C/C++程序需要重新配置文件夹.vscode以及三个配置文件，所以建议在最外层的文件夹中创建配置文件夹.vscode及配置文件，在子文件夹中保存C/C++程序

     2、关于C/C++输出的中文乱码：在vscode的setting.json文件中做如下配置

 

        3、查看gcc编译器版本号和安装路径的指令：gcc -v -E -x c++ -
