Re: [Boost-users] boost::any_range with an abstract class reference

Compilation fails with the following error ( looks like any_range value is supposed to be copy-constructable? ) Is there any workaround?

I don't know the details of any_range, but here is a hack: Change Line 49-51 of typedef typename remove_const< typename remove_reference<Reference>::type >::type reference_as_value_type; to typedef typename mpl::if_< mpl::or_< is_abstract , is_array > , Reference , typename remove_const< typename remove_reference<Reference>::type >::type >::type reference_as_value_type; Regards, Michel P.S. When you post a thread to Boost mailing list, please include the library name (in the bracket) at the beginning of the subject. (e.g. [range] any_range with an abstract class reference) This will draw more attention to the post.
