Env include path not working in header files #674

Closed meclondrej closed 3 months ago

meclondrej commented 3 months ago

I installed coc-clangd with :CocInstall coc-clangd. I set my include path into C_INCLUDE_PATH, colon separated. When i open a .c file, i can see my includes in the autocomplete, causing no issues, however when i open a .h file, the default include path is used, with no paths from C_INCLUDE_PATH available.

You need to setup compile_commands.json for your project, to make clangd can understand your code. https://clangd.llvm.org/installation#project-setup
