I don't see where these symbols are declared.

What is the output from running

  nm boolSparse.o | grep mx_el_eq

on your system?  I'm just picking mx_el_eq as an example, since I
suspect the problem and solution is the same for all these symbols.
If that command produces C++ mangled names, then does AIX provide a
utility for demangling them, like c++filt?  If so, plesae use that to
demangle the names.

As far as I can tell, the only mx_el_eq symbols should be these

  mx_el_eq(SparseBoolMatrix const&, bool const&)
  mx_el_eq(SparseBoolMatrix const&, SparseBoolMatrix const&)
  mx_el_eq(bool const&, SparseBoolMatrix const&)

and they should be defined in boolSparse.o.  I don't see where the
versions with double scalar arguments are coming from.
