Well, he was asking about a C library, a Lua module that is.

I would suggest taking some existing one, s.a. Lua Lanes or maybe  
LuaSocket, and seeing how that is being built.

There is also a wiki page about OS specific issues, which are a few.

It wouldn't be bad to have a simple, multi-OS makefile sample  
somewhere. Maybe you will do that?

Depends on your system, which you did not name to us.

On OS X with fink Lua 5.1:

	$ pkg-config lua --variable=INSTALL_LMOD
	/sw/share/lua/5.1

	$ pkg-config lua --variable=INSTALL_CMOD
	/sw/lib/lua/5.1

Those variables are in the 'etc/lua.pc' that comes with Lua itself, so  
maybe this works with other distributions as well.
