Subject: Virtual packages in findlib
Date: Tue, 7 Jul 2009 11:07:55 -0700 (PDT)	[thread overview]

Hi,

(This is somewhat related to my previous question; having an order-preserving
Ocamlbuild would be moot if findlib supported some sort of virtual packages).

Suppose that for successful linking you need a package B to appear after
package A1.  However, A1 is only one particular instantiation of A-ness.
You could replace A1 with A2 or A3, and the program would also link and run.

Is there a way of expressing this sort of dependency with findlib?  Something
like "requires = A1 | A2 | A3".  Or even better, allowing packages A1, A2,
and A3 to provide a virtual package "A", and make B depend on that.  (The
Debian folks will recognise this pattern).

Best regards,
Dario Teixeira
