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
}
