VSCode 配置 C/C++ 环境-编程知识

VSCode 配置 C/C++ 环境

1 安装 VSCode

直接去官网(https://code.visualstudio.com/)下载并安装即可。

2 配置C/C++编译环境

方案一
如果是在Windows，需要安装 MingW，可以去官网(https://sourceforge.net/projects/mingw-w64/)下载安装包。
注意安装路径不要出现中文。

打开 windows shell 界面，输入mingw-get install gcc、mingw-get install g++。
如果安装的时候提示安装包被错误下载，可使用方案二安装。
方案二
进入网址https://sourceforge.net/projects/mingw-w64/files/，下滑，下载图中所示压缩包。

找一个无中文路径解压缩。
添加环境变量。在Path中加入解压后的文件夹中的bin目录，如C:\ProgramFiles\MinGW\mingw64\bin。
测试
在 windows shell 界面输入gcc -v、g++ -v，正确出现版本号则配置成功。

3 安装插件

搜索插件 C/C++ 和 Code Runner 并安装。

4 编辑配置文件

首先新建一个文件夹，并用 VSCode 打开。
在该文件夹中创建名为 .vscode 的文件夹。
在该文件夹中创建下面几个文件。以后的C/C++代码文件必须放在这个Code文件夹里，或者说有.vscode文件夹的文件夹里。

c_cpp_properties.json
将 compilerPath 换成你的g++路径。

{"configurations": [{"name": "Win64","includePath": ["${workspaceFolder}/**"],"defines": ["_DEBUG", "UNICODE", "_UNICODE"],"windowsSdkVersion": "10.0.18362.0","compilerPath": "C:\\MinGW\\bin\\g++.exe","cStandard": "c17","cppStandard": "c++17","intelliSenseMode": "gcc-x64"}],"version": 4
}

launch.json
将 miDebuggerPath 换成你的gdb路径。

{"version": "0.2.0","configurations": [{"name": "(gdb) Launch", "type": "cppdbg", "request": "launch", "program": "${fileDirname}\\${fileBasenameNoExtension}.exe", "args": [], "stopAtEntry": false,"cwd": "${workspaceRoot}","environment": [],"externalConsole": true, "MIMode": "gdb","miDebuggerPath": "C:\\MinGW\\bin\\gdb.exe","preLaunchTask": "g++","setupCommands": [{"description": "Enable pretty-printing for gdb","text": "-enable-pretty-printing","ignoreFailures": true}]}]
