Mac上利用VScode配置c/c++開發環境

Mac上利用VScode配置c/c++開發環境

哭遼，Typora里面最好不要插入表情，不然保存會閃退

1. 首先你要有一個vscode
2. 在擴展里面下載c/c++

第一步

⬆+com+p 打開命令模式：選擇c/c++： 編輯配置（edit configuration）
然后再自動生成的.vscode目錄，打開c_cpp_properties.json。利用老哥的文件示例：

{
    "configurations": [
        {
            "name": "Mac",
            "includePath": [
                "${workspaceFolder}/**",               	              
              	"/Library/Developer/CommandLineTools/usr/include/c++/v1",
                "/usr/local/include",
                "/Library/Developer/CommandLineTools/usr/lib/clang/11.0.0/include",
                "/Library/Developer/CommandLineTools/usr/include"
            ],
            "defines": [],
            "macFrameworkPath": [
                "/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/System/Library/Frameworks",
                "/System/Library/Frameworks",
                "/Library/Frameworks"
            ],
            "compilerPath": "/usr/bin/clang",
            "cStandard": "c11",
            "cppStandard": "c++17",
            "intelliSenseMode": "clang-x64"
        }
    ],
    "version": 4
}

將要用到的庫添加到includePath里面

第二步：

[⇧⌘P]打開命令模式，選擇[Tasks: Configure Task]命令，選擇的模板為MSBuild，回車后會自動在.vscode目錄下生成一個tasks.json文件，下面給出我的文件示例：

{
    // 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"
        }
    ]
}

• 很多參數咱也不懂，先照抄吧

該文件其實就是一個命令行構建工具。
把運行程序時在終端輸入的命令和參數對於"command"和"args"的值
輸入shift+command+b，便可構建成功，生成可執行文件「文件名」.out

第三步：

[⇧⌘P]打開命令模式，選擇[Debug: Open launch.json]命令，選擇的模板為C/C++，回車后會自動在.vscode目錄下生成一個launch.json文件，下面給出老哥的文件示例：

{
    // 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": "c/c++ Launch",
            "type": "cppdbg",
            "request": "launch",
            "program": "${fileDirname}/${fileBasenameNoExtension}.out",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": true, //true代表會彈出外面終端，顯示
            "MIMode": "lldb",
            "preLaunchTask": "build c++",
            "logging": {//這段會添加一大段沒用的建議刪除
                "trace": true,
                "traceResponse": true,
                "engineLogging": true
            }
        }
    ]
}

完成這三步C++開發環境就配置好了，接下來就可以編譯，運行，調試C++程序了
[⇧⌘B]是編譯程序，[⇧⌘R]是運行程序，如果安裝了插件『Code Runner』可以直接運行程序
如果需要調試，那就按F5，進入調試模式即可

[⇧⌘B]會編譯生成.out文件，再按[⇧⌘R]會在終端窗口顯示運行結果 或者 進行交互。
