Subject: Re: building extension modules, and linking

If you run nm on any extension shared object, you'll generally see
that the link-editor simply marks as unresolved the references in your
code to functions in the Ruby runtime libraries. As someone else
pointed out, these symbols are already available in-process (because
the Ruby runtime defines them) when your extension is dynamically
loaded. So the linker doesn't need to know where they're coming from.

By chance are you primarily a Java programmer? I ask because the Java
build system is very picky about inspecting code that is referenced by
your code, in ways that C is not.
