Mac使用Visual Studio Code開發C++

在VS Code上使用Clang進行編譯和調試

• 安裝Visual Studio Code

• 安裝C++擴展插件

• 安裝Clang插件

• 在環境變量中添加code命令(如果已經配置了，跳過)

  • “Shift+Command+P”打開Command Palette
  • 輸入“Shell”，選擇“Shell Command: Install ‘code’ command in PATH”
  • 關閉VS Code

• 在一個文件夾中啓動VS Code

  • 步驟

    mkdir cprojects
    cd cprojects
    mkdir cpptest
    cd cpptest
    code .
    

• 創建3個json文件

  • c_cpp_properties.json指定編譯器的路徑

    • “Shift+Command+P”打開Command Palette
    • 輸入“C/C++”，選擇“Edit Configurations”

     {
     "configurations": [
         {
             "name": "macOS",
             "includePath": [
                 "${workspaceFolder}/**"
             ],
             "defines": [],
             "macFrameworkPath": [
                 "/System/Library/Frameworks",
                 "/Library/Frameworks"
             ],
             "compilerPath": "/usr/bin/clang",
             "cStandard": "c11",
             "cppStandard": "c++17",
             "intelliSenseMode": "clang-x64"
         }
     ],
     "version": 4
     }
    

  • tasks.json指定如何構建可執行文件

    • “Shift+Command+P”打開Command Palette
    • 輸入“task”，選擇“Tasks: Add a default build task”->“others

    {
    "version": "2.0.0",
    "tasks": [
        {
            "label": "Build with Clang",
            "type": "shell",
            "command": "clang++",
            "args": [
                "-std=c++17",
                "-stdlib=libc++",
                "helloworld.cpp",
                "-o",
                "helloworld.out",
                "--debug"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            }
        }
    ]
    }
    

  • launch.json進行調試器配置

     {
     "version": "0.2.0",
     "configurations": [
         {
             "name": "(lldb) Launch",
             "type": "cppdbg",
             "request": "launch",
             "program": "${workspaceFolder}/helloworld.out",
             "args": [],
             "stopAtEntry": true,
             "cwd": "${workspaceFolder}",
             "environment": [],
             "externalConsole": true,
             "MIMode": "lldb",
             "logging": {
                 "trace": true,
                 "traceResponse": true,
                 "engineLogging": true
             }
         }
     ]
     }
    

• helloworld.cpp

  #include<iostream>
  using namespace std;
  int main()
  {
      cout << "Hello World" <<endl;
      return 0;
  }
