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 }
