Hi again,
FWIW, problem solved if we linked with LDFLAGS=-Wl,-flat_namespace. I
noticed that 'libtool.m4' has some code to enforce flat_namespace under
certain circumstances on darwin (see below). Would it make sense to
switch to flat_namespace in even more cases, since the default seems
problematic, or are there strong reasons to prefer default in the
general case?
Cheers,
Peter
