c++ - 如何去除 vsCode 中的 C++ 11 扩展警告

Question

当我使用 auto 类型时，我的 vscode 中只有一个警告

'auto' type specifier is a C++11 extension [-Wc++11-extensions] (14, 10)

那么我怎样才能消除这个警告

Answer 1

您必须编辑 c_cpp_properties.json 文件。看一个例子here .

{
  "env": {
    "myDefaultIncludePath": ["${workspaceFolder}", "${workspaceFolder}/include"],
    "myCompilerPath": "/usr/local/bin/gcc-7"
  },
  "configurations": [
    {
      "name": "Mac",
      "intelliSenseMode": "clang-x64",
      "includePath": ["${myDefaultIncludePath}", "/another/path"],
      "macFrameworkPath": ["/System/Library/Frameworks"],
      "defines": ["FOO", "BAR=100"],
      "forcedInclude": ["${workspaceFolder}/include/config.h"],
      "compilerPath": "/usr/bin/clang",
      "cStandard": "c11",
      "cppStandard": "c++17",
      "compileCommands": "/path/to/compile_commands.json",
      "browse": {
        "path": ["${workspaceFolder}"],
        "limitSymbolsToIncludedHeaders": true,
        "databaseFilename": ""
      }
    }
  ],
  "version": 4
}

在该文件中列出了一个选项 cppStandard。它必须设置为 c++11。然后 auto 将被支持。
