Emscripten Resolve Header Problem

Background

I am trying to build Lua 5.4.0 for WASM running in node.js using emscripten.

In the past I have successfully done this with the old emacripten backend and c++ using a Lua wrapper (sol) but I didn't really learn anything with this abstraction, also I would prefer to write C.

Problem

For some reason I have had little success getting the headers to resolve. Here are the compiler flags in use (ran from shell in JavaScript).

Now I can compile a basic hello world but adding the headers, emacripten complains of unknown symbol luaL_newstate 🤷‍♂️, I have a liblua.a built from Lua src, I have -I and -L.

Anything obvious standing out?
Ive been trying things for days and searching all over with limited success.
