Linter error 'stdlib.h' file not found clang (pp_file_not_found)

Open ShortArrow opened this issue 8 months ago • 2 comments

Want

I want to know which stdlib.h header files are being used.

Hope

I think more people will want to use clangd for coding from now on, so I'd like to make it easy for even C++ beginners to set up clangd.

Expected

Disable Lint error without change other clangd config. Must to do only I need is change including path config in clangd config.

Actual

In included file: 'stdlib.h' file not found clang (pp_file_not_found) [1, 10]

Tried

Arduino core is installed in Project directory by arduino-cli with arduino-cli.yaml. So, I hoped I can find out in project directory. But I tried search with fzf, found many stdlib.h, I was confused.

CLI direct use

cd ./poc_renesas_uno
clangd --check=./main.cpp

Thanks

I hope that the Arduino community is welcoming and accommodating to beginners. I understand that responding to requests like this issue can be cumbersome and anoying and sometimes distracts from the main focus.

I will not forget to express my gratitude to everyone who has taken the time to read this.
