Looks like you got bitten by the C++ name mangling.

Try the following change:
----------
extern "C" {
#include <lua.h>
}

int main() {
  lua_State *s = lua_open(256);
  return 0;
}
------------

If this doesn't help, then it is time to
check other things. I personally include lua into
my project by adding the source files to to the VC
project. Because of their small size, I have
never felt any need to use a .lib for Lua.
