after looking at the testcase you actually provided (as opposed to some other
archive), I understand the problem better.
You define libmpi which happens to be built with <parallelism>mpi, which is
expanded to reference to libmpi, so libmpi is built again, giving the error.
The solution which works for me is:
1. Moving <define> and <include> from mpiheaders to libmpi
2. Marking libmpi "explicit" so that it's built only when explicitly
The resulting definition looks like:
: # sources
: # requirements
: # default-build
: # usage-requirements
explicit libmpi ;
I'll think if this "reference to self" should be error or just ignored.
