vscode 配置c++ 添加头文件 VSCode配置C/C++并添加非工作区头文件的方法

下文均在Windows环境下：

配置C/C++

按照教程安装MinGW，并配置gcc和g++，配置方法有两种：

1 GUI配置

在MinGW Installation Manager中选取对应的Package，然后Installation->Apply Changes，如果失败则多试几次。

2 控制台配置

配置系统环境变量：

1.xxx/MinGW/bin;

即安装MinGW目录下的bin文件夹

然后在cmd中输入：

1.mingw-get install gcc g++ mingw32-make

添加非工作区头文件

•Ctrl+Shift+P 。选择c_cpp_properties.json，includePath和browse中都需要添加需要的头文件路径；

{  
  "configurations": [  
    {  
      "name": "MinGW",  
      "intelliSenseMode": "gcc-x64",  
      "compilerPath": "C:/MinGW/bin/gcc.exe",  
      "includePath": [  
        "${workspaceFolder}",  
        "C:/test"  
      ],  
      "defines": [],  
      "browse": {  
        "path": [  
          "${workspaceFolder}",  
          "C:/test"  
        ],  
        "limitSymbolsToIncludedHeaders": true,  
        "databaseFilename": ""  
      },  
      "cStandard": "c11",  
      "cppStandard": "c++17"  
    }  
  ],  
  "version": 4  
}

假设C:/test是非工作区头文件路径。
•tasks.json中添加链接库，"-I"

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

gcc带不同参数的含义:"-g"产生调试信息，"-c"编译中间目标文件，"-I"指定链接库，"-o"生成指定命名的可执行文件。

知识点补充：vscode添加头文件路径

win+p 。选择c_cpp_properties.json

 {
"configurations": [
{
"name": "Linux",
"includePath": [
"${workspaceFolder}/**",
"/usr/src/linux-headers-4.15.0-36-generic/include/" //此处添加头文件路径，
],
"defines": [],
"compilerPath": "/usr/bin/gcc",
"cStandard": "c11",
"cppStandard": "c++17",
"intelliSenseMode": "gcc-x64"
}
],
"version": 4
}
