Compile Lua from source and create C module with it - c

Question

I thought of compiling Lua from source code and then create a C module.
I compiled Lua with success but I can't build my C module.
So, I compiled Lua like this:
gcc -o Lua *.c -Os -std=c99
Compiled my module like this:
gcc -Wall -shared -fPIC -o module.so -I. module.c
But there are a few errors here:
Undefined symbols for architecture x86_64:
"_lua_pushcclosure", referenced from:
_luaopen_module in module-fb0b1f.o
"_lua_pushnumber", referenced from:
_super in module-fb0b1f.o
"_lua_setglobal", referenced from:
_luaopen_module in module-fb0b1f.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
The C module itself:
#include "lua.h"
static int super(lua_State* L) {
lua_pushnumber(L, 5);
return 1;
}
int luaopen_module(lua_State* L) {
lua_register(L, "super", super);
return 0;
}
My Lua script:
require("module")
print(super())
I'm on Unix based system (Mac), but I want it to work on Linux as well.
Edit:
Problem to compile C module was fixed by entering -bundle -undefined dynamic_lookup instead of -shared (Thanks lhf).
But I can't import the module in Lua.
> require("module")
error loading module 'module' from file './module.so':
dynamic libraries not enabled; check your Lua installation
Another thing:
This seems to be a quick fix only; -bundle -undefined dynamic_lookup. This does not work on Linux. How can I do this on linux? I wanted a solution for Unix based systems.

Download Lua from lua.org and build Lua with make macosx. See Getting started.
Use -bundle -undefined dynamic_lookup instead of -shared to build module.so.
Use require"module" to load it into Lua.
Call super.
Make sure you're running the lua program that you have built above, not some other version that is installed.
