I'm trying to config a cpp code environment with Zephyr in vscode (clangd plugin), basically west build generate a compile_commands.json which leads the analysis of clangd server... Though the west build system success, clangd keeps warning me about annoying missing header file of <bits/c++config.h> or something else.
I have already followed the tutorial that menuconfig to config c++ standard lib as GNU C++ Lib, and it appears to build the files as expected.

How exactly can we setup an environment for c++ coding? I have already installed the Zephyr SDK, and according to tutorial it should contains a certain version of std library, can i choose to use that?
