Development setup, clangd configuration

[debdutdeb]

Hi!

I am trying to get lsp working. Using clangd (not vscode's extension). Generated compile commands using ./configure -C as https://github.com/nodejs/node/blob/c923ce7414e2c7135afb00847d7b2e071a4f2317/configure.py#L863-L867

But when trying to start lsp, first I got memory not found which fixed by specifying include path

# .clangd
CompileFlags:
  Add: [-std=c++11, -I/usr/include/x86_64-linux-gnu/c++/11, -I/usr/include/c++/11]

But now, diagnostics is filled with

src/node.cc|1 col 1 error| Too many errors emitted, stopping now
src/node.cc|1 col 1 error| Too many errors emitted, stopping now

Is there any documentation on standard configuration? Even if for vscode extension's.

Distributor ID:	Pop
Description:	Pop!_OS 22.04 LTS
Release:	22.04
Codename:	jammy

Might I have missed some document that outlines this?

Thanks in advance.

Edit:: forgot to mention, build works just fine.

Edit2: switching to gnu++17 in .clangd did not help either. Noticed std in compile_commands.

I was looking for this ... I needed the compile_commands.json to make clion work, you saved me!
