[Boost.Intrusive] Intrusive doubly linked list does not compile on xlC11.1
Hi, I'm trying to compile the intrusive doubly linked list example from http://www.boost.org/doc/libs/1_47_0/doc/html/intrusive/list.html#intrusive.... using xlC11.1 on AIX/Power5+ and I am getting the following error: 1540-0216 (S) An expression of type "overloaded function: base_hook_traits<MyClass,boost::intrusive::list_node_traits<void *>,1,boost::intrusive::default_tag,1>::to_node_ptr" cannot be converted to type "boost::intrusive::list_node<void *> *(boost::intrusive::detail::base_hook_traits<MyClass,boost::intrusive::list_node_traits<void *>,1,boost::intrusive::default_tag,1>::*)(MyClass &)".

Any known workarounds? Thanks

It happens in Boost 1.48 as well.

Is xlC standard conforming enough? I don't access to that compiler so I don't test it with that toolset. Ion

xlC 11.1 is quite good and till now I haven't encountered major issues. I'm willing to go through the code and fix intrusive for xlC, provided that I get some guidance. For starters, the is_convertible is invoking undefined behavior. xlC rightfully warns against passing a non-POD through ellipsis (only PODs are allowed there, otherwise it is considered undefined behavior: "/scratch/ipapado/usr/include/boost/intrusive/detail/mpl.hpp", line 70.45: 1540-2924 (W) Cannot pass an argument of non-POD class type "boost::intrusive::detail::is_convertible<boost::intrusive::detail::member_hook_traits<MyClass,boost::intrusive::list_member_hook<boost::intrusive::none,boost::intrusive::none,boost::intrusive::none>,&MyClass::member_hook_> *,boost::intrusive::detail::default_hook_tag *>::false_t" through ellipsis. Changing it to template <class T, class U> class is_convertible { typedef char true_t; /**/ struct /**/ false_t { char dummy[2]; }; static true_t dispatch( /**/ U* /**/ ); static false_t dispatch(...); public: static const bool value = sizeof(dispatch(static_cast<T*>(0))) == sizeof(true_t); }; or using the one provided in type_traits, resolves the warnings. Still trying to figure out why the error with the conversion exists though.
