The problem is the last line.  The "write" function isn't built into the
core lua language, it's actually part of the add-on I/O library.  You must
initialize the standard libraries in your host "C" program before they can
be used (lua.exe and luac.exe do this for you).

See Section 6 of the manual for more info, but here's the basic idea:

extern "C"
{
#include <lualib.h>
}

....

lua_baselibopen(L);
lua_strlibopen(L);
lua_mathlibopen(L);
lua_iolibopen(L);
