vscode配置C/C++笔记（硬要使用C++11）_vscode应输入声明

• 1 launch.json 控制的是debug的配置

  {
      "version": "0.2.0",
      "configurations": [
  
          {
              "type": "lldb",
              "request": "launch",
              "name": "Debug",
              //"program": "${workspaceFolder}/test.out",
              //上一行是官方写法，但是不同的cpp调试都要改配置，非常麻烦
              "program": "${workspaceFolder}/${fileBasenameNoExtension}",
              "args": [],
              "cwd": "${workspaceFolder}",
              "preLaunchTask": "Build with Clang"
          }
      ]

NOTE：如果要配置opencv环境：

• 查找opecv库的路径

  brew info opencv

• 3 settings.json 解决“C++应输入声明”的错误

  {
      "C_Cpp.errorSquiggles": "Disabled"
  }

• 4 tasks.json

      "version": "2.0.0",
      "tasks": [
          {
              "label": "Build with Clang",//这个任务的名字在launch.json最后一项配置
              "type": "shell",
              "command": "clang++",
              "args": [
                  "-std=c++11",
                  "-stdlib=libc++",
                  //"test.cpp",这里是官方写法，不具有普遍性，注意两个配置文件的统一性即可
                  "${fileBasenameNoExtension}.cpp",
                  "-o",
                  //"test.out",
                  "${fileBasenameNoExtension}",
                  "--debug"
              ],
              "group": {
                  "kind": "build",
                  "isDefault": true
              }

配置完上述4个文件后，在debug界面点击debug可正确执行

但直接运行文件时，依然不会按照c++11语法进行编译，解决办法如下

https://www.cnblogs.com/TAMING/p/10177322.html

1 安装Code Runner
2 依次找到:文件>首选项>设置>用户设置>扩展>run code configurate>Executor Map
3 然后点击在settings.json中编辑


4 如果发现无code-runner.executorMap配置，仅需在末尾输入code-runner.executorMap利用自动补全按一下回车，会生成各个语言的模板

找到对应的语言这里以cpp为例:
cd $dir && g++ $fileName -o $fileNameWithoutExt && $dir$fileNameWithoutExt
其中
$dir代表文件路径
$fileName代表文件名
$fileNameWithoutExt代表文件名对应的可执行文件文件名
翻译过来就是切换(cd指令)到源文件所在路径,编译(g++)源文件,输入(-o参数)成对应文件名的可执行文件,在执行
比如将c++默认的g++指令换成clang(clang编译指令格式为clang x.cpp -o x.exe所以其他不用修改,具体的指令需要根据编译器命令行参数来确定)

• 5 run code configurate——setting.json
  根据我的需求，我只需要加个参数-std=c++11

  "cpp": "cd $dir && g++ -std=c++11 $fileName -o $fileNameWithoutExt && $dir$fileNameWithoutExt",

• 6 每次执行前都清空终端的配置方法
  安装Code Runner。mac下按shift + command + X，搜索Code Runner，点击设置图标，选择“扩展配置”，将Clear Previous Output的复选框勾上：
