Well, first of all, when I create a separate test Jamfile for uBLAS and
subinclude it, I get:

    Cannot extract library name from path ../libs/numeric/ublas

This is because when it's in status, 'get-library-name' just returns empty
string. When it's not in status, the 'get-library-name' rule is called with


and the first regex does not match because there's no "test" in the name, and
second regex does not match because there is slash between "numeric" and
"ublas". I've applied the attached patch -- since it strictly adds the set of
arguments to 'get-library-name' on which that function does not fail, I think
it should not cause any problems.

Another question whether all libraries should have their test Jamfiles under
"test" directory -- which is not what uBLAS does.

And now back to original question. As I understand, the 'get-library-name'
rules gets the location of *Jamfile*. The primary heuristic is that location
is "libs/ <library-name> / test / whatever". Why can't this logic be applied
to the name of source file which bjam prints -- and be implemented in

I'm asking because it seems to be that it's better to have smart logic in
process_jam_log than in jam.
