Problem description

Hello,
I'm using pop os, i want to setup lunarvim for competitive programming.
But I think it's not including header files from designated place.
How to update my config (clangd.json or inside config.lua) file to remove these errors?

In my system, these header files are located in
/usr/include/x86_64-linux-gnu/c++/11/

LunarVim version

release-1.3

Neovim version (>= 0.9.1)

neovim-0.9-d1c1bace

Do you export the CXXFLAGS= correctly in your current terminal session?

[yashwardhan-gautam]

No, I haven't done that. Can you explain a bit more on that?

you can have a look at how to configure .clangd file . As far as I can see, this is not a lvim issue. I use C++ and Cmake
https://clangd.llvm.org/config#compileflags
you add this in your .clangd file

CompileFlags:                     
  Add: [-I/usr/include/x86_64-linux-gnu/c++/11/,  --include-directory=/usr/include]

I just used cmake to generate compile_commands.json which helps the clangd server to recognized header files.

Here's my example repo:

this is not an lvim issue. this is learning C++ issue. you can use CMake as a build system and and add

set(CMAKE_EXPORT_COMPILE_COMMANDS ON)

on top your project after project name like this

cmake_minimum_required(VERSION 3.21 FATAL_ERROR)
project(
  message-package_project
  VERSION 1.2.1
  LANGUAGES CXX)

set(CMAKE_CXX_STANDARD 23)
set(CMAKE_CXX_STANDARD_REQUIRED True)
set(CMAKE_CXX_EXTENSIONS OFF)
set(CMAKE_EXPORT_COMPILE_COMMANDS ON)

So this can be closed. This is not lvim related.
