macOS上使用VScode编译配置C++语言开发环境

本文介绍macOS上使用VScode编译配置C++语言开发环境

1.准备工作

安装C/C++插件

在这里插入图片描述

2.配置c_cpp_properties.json文件

[⇧⌘P]打开命令模式，选择[C/Cpp: Edit Configurations(JSON)]命令，回车后会自动生成一个.vscode目录，目录下有一个c_cpp_properties.json文件，如下所示：

{"configurations": [{"name": "Mac","defines": [],"macFrameworkPath": ["/System/Library/Frameworks","/Library/Frameworks","${workspaceFolder}/**"],"compilerPath": "/usr/bin/g++","cStandard": "c11","cppStandard": "c++17","intelliSenseMode": "clang-x64","browse": {"path": ["${workspaceFolder}"],"limitSymbolsToIncludedHeaders": true,"databaseFilename": ""}}],"version": 4
}

3.配置tasks.json文件

[⇧⌘P]打开命令模式，选择[Tasks: Configure Task]命令，选择的模板为MSBuild，回车后会自动在.vscode目录下生成一个tasks.json文件：

{// See https://go.microsoft.com/fwlink/?LinkId=733558// for the documentation about the tasks.json format"version": "2.0.0","tasks": [{"label": "build c++","type": "shell","command": "g++","args": ["${file}","-std=c++17","-g","-Wall","-lm","-o","${fileDirname}/${fileBasenameNoExtension}.out"],"group": "build","presentation": {"reveal": "silent","panel": "shared","echo": true,"focus": false,"showReuseMessage": true,"clear": false},"problemMatcher": "$gcc"},{"label": "run c++","type": "shell","dependsOn": "build c++","command": "${fileDirname}/${fileBasenameNoExtension}.out","presentation": {"focus": true},"group": "test"}]
}

4.配置launch.json文件

方式1：

方式2：

[⇧⌘P]打开命令模式，选择[Debug: Open launch.json]命令，选择的模板为C/C++，回车后会自动在.vscode目录下生成一个launch.json文件：

{// Use IntelliSense to learn about possible attributes.// Hover to view descriptions of existing attributes.// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387"version": "0.2.0","configurations": [{"name": "(lldb) Launch","type": "cppdbg","request": "launch","program": "enter program name, for example ${workspaceFolder}/a.out","args": [],"stopAtEntry": false,"cwd": "${workspaceFolder}","environment": [],"externalConsole": false,"MIMode": "lldb"}]
}
