I tried a global replace of apply_if with eval_if; however, I got: <-------------------- intel-linux.compile.c++ ../../../../bin.v2/lje/libs/managed_ptr/test/intel-linux/debug/smart_ptr_test.o ../../../boost/managed_ptr/smart_ptr.hpp(204): error: class "boost::mpl::eval_if<boost::mpl::bool_<false>::type, boost::mpl::identity<boost::ref_counted<boost::mpl::_>>, boost::detail::get_policy<boost::mpl::list<boost::managed_ptr::refcycle_counted_curry_prox_visitor<boost::managed_ptr::refcycle_prox_visitor_abs::this_type>::owner_refptr<boost::mpl::_>, boost::empty_policy, boost::empty_policy, boost::empty_policy, boost::mpl::na, boost::mpl::na, boost::mpl::na, boost::mpl::na, boost::mpl::na, boost::mpl::na, boost::mpl::na, boost::mpl::na, boost::mpl::na, boost::mpl::na, boost::mpl::na, boost::mpl::na, boost::mpl::na, boost::mpl::na, boost::mpl::na, boost::mpl::na>, boost::ownership_policy_tag, boost::ref_counted<boost::mpl::_>>::iter_>" has no member "type" >::type type; ^ detected during: instantiation of class "boost::detail::get_policy<Sequence, Category, Default> [with Sequence=boost::mpl::list<boost::managed_ptr::refcycle_counted_curry_prox_visitor<boost::managed_ptr::refcycle_prox_visitor_abs::this_type>::owner_refptr<boost::mpl::_>, boost::empty_policy, boost::empty_policy, boost::empty_policy, boost::mpl::na, boost::mpl::na, boost::mpl::na, boost::mpl::na, boost::mpl::na, boost::mpl::na, boost::mpl::na, boost::mpl::na, boost::mpl::na, boost::mpl::na, boost::mpl::na, boost::mpl::na, boost::mpl::na, boost::mpl::na, boost::mpl::na, boost::mpl::na>, Category=boost::ownership_policy_tag, Default=boost::ref_counted<boost::mpl::_>]" at line 225

I've searched mail archives for apply_if and eval_if and looked at: http://www.boost.org/libs/mpl as directed by comments in eval_if.hpp; however, none were any help except the one I'm replying to. How does one replace apply_if with eval_if to avoid the above error message. TIA. Regards, Larry
