在ubuntu中配置vscode 的 C++ 环境

安装C++环境

sudo apt install gcc
sudo apt install g++

配置vscode

点击左侧齿轮按纽，点击弹出窗口的齿轮按钮添加环境

然后点击设置会生成一个后缀为json的文件，将其中的内容修改为

  {  
  // Use IntelliSense to learn about possible attributes.  
  // Hover to view descriptions of existing attributes.

  "version": "0.2.0",  
  "configurations": [  
      {  
          "name": "(gdb) Launch",  
          "type": "cppdbg",  
          "request": "launch",  
          "program": "${workspaceFolder}/${fileBasenameNoExtension}.out",  
          "args": [],  
          "stopAtEntry": true,  
          "cwd": "${workspaceFolder}",  
          "environment": [],  
          "externalConsole": false,  
          "MIMode": "gdb",  
          "preLaunchTask": "build",  
          "setupCommands": [  
              {  
                  "description": "Enable pretty-printing for gdb",  
                  "text": "-enable-pretty-printing",  
                  "ignoreFailures": true  
              }  
          ]  
      }]  
  }

在同一文件夹下创建名为tasks.json的文件,并将其修改为

{  
    // See https://go.microsoft.com/fwlink/?LinkId=733558  
    // for the documentation about the tasks.json format  
    "version": "2.0.0",  
    "tasks": [  
        {  
            "label": "build",  
            "type": "shell",  
            "command": "g++",  
            "args": ["-g", "${file}", "-std=c++11", "-o", "${fileBasenameNoExtension}.out"]  
        }  
    ]  
}
