The static linking schema can be used on all versions of
SWI-Prolog. Whether or not dynamic linking is supported can be deduced
from the Prolog flag open_shared_object
(see
current_prolog_flag/2).
If this Prolog flag yields true,
open_shared_object/2
and related predicates are defined. See
section 12.2.3 for
a suitable high-level interface to these predicates.
