I haven't used VADS, but 'min_tasking.a' sounds like part of the
run-time system. Are you doing anything in Ada that requires tasking?
This includes explicit tasks, as well as delay statements.

You need to arrange for the Ada elaboration and finalization code to
be called from your C++ main. Consult your compiler documentation
about how to do that.

If you'll post the exact code and error messages, maybe we can be more
helpful.
