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}
