Dynamically linking .obj files is basically wrapping all together 
to a shared library, loaded at runtime. So you need an interface 
that interops with your script language that must provide options 
to exchange input/output, registering functions that are callable 
from your script while your library is loaded and such stuff. The 
final logic is up to you.
