How to use vscode-clangd with c++11?

Question

How to conf vscode-clangd to use c++11 for lint?

I added both complie_commands.json and complie_flags.txt in workshop.

workshop
|-complie_commands.json
|-complie_flags.txt
|-list.cpp

complie_commands.json

[
   { "directory": "pathto/workshop/",
     "command": "/opt/rh/llvm-toolset-7/root/usr/bin/clang++ -o file *cpp -std=c++11"}
]

compile_flags.txt

-std=c++11

It couldn't recognize auto with error:

'auto' type specifier is a C++11 extension

@TonyTannous: "vscode" is "Visual Studio Code", which is only in name and looks related to the regular Visual Studio. — MSalters, Sep 12 '19 at 11:21
I'd expect C++11 to be detected from`compile_commands.json`, related: https://stackoverflow.com/questions/51885784/how-to-setup-vs-code-for-c-with-clangd-support — Ciro Santilli OurBigBook.com, Mar 23 '23 at 10:33

Set cppStandard in c_cpp_properties.json to c++11. e.g.:

{
  "env": {
    "myDefaultIncludePath": ["${workspaceFolder}", "${workspaceFolder}/include"],
    "myCompilerPath": "/usr/local/bin/gcc-7"
  },
  "configurations": [
    {
      "name": "Linux",
      "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++11",
      "compileCommands": "/path/to/compile_commands.json",
      "browse": {
        "path": ["${workspaceFolder}"],
        "limitSymbolsToIncludedHeaders": true,
        "databaseFilename": ""
      }
    }
  ],
  "version": 4
}

@abhi3700 I don't imagine any of the C++ plugin works if it is disabled? — Alan Birtles, Mar 28 '22 at 08:27
