stddef.h not found

[chunkbanned]

I've installed clang, gcc, llvm, everything
I've also built clang from source which took hours and still didnt work
and I constantly just get this error
I am on endevourOS which is Arch Linux based

  /usr/include/sys/types.h:144:10: fatal error: 'stddef.h' file not found
  thread 'main' panicked at /home/riley/.cargo/registry/src/index.crates.io-6f17d22bba15001f/redis-module-2.0.7/build.rs:65:10:
  error generating bindings: ClangDiagnostic("/usr/include/sys/types.h:144:10: fatal error: 'stddef.h' file not found\n")
  note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

If you would like anymore details please ask and I will be happy to provide

Same problem here on Centos Stream 9
edit : dnf install clang fixed it
