&obj::method is actually of type void (obj_base::*) (), and while mem_fn recognizes references to the 'base' type (obj_base&), it cannot tell whether obj& is a smart pointer or an object reference.
I can probably fix this by using boost::is_convertible<U, T> but unfortunately it's known to break some compilers. Food for thought. Thanks for the bug report. :-)
Thank you for the explaination Peter. Your change was a translation problem on my part. Apologies. Is there an appropriate work around? I have been using: namespace boost { inline obj* get_pointer( obj & p ) { return &p; } } As this was the source of the compiler error. Is there a better work around? I am leary of a full template replacement for this because I dont know what the side affects would be: namespace boost { template < class T > inline T* get_pointer( T & r ) { return &r; } } ...Duane
