Hi, Thanks for your fast feedback and sorry for the lack of information I gave you in my last email. I stripped down everything I could and found the problem. There are two overloaded member functions and somehow in a template-context, the compiler gets confused. Is there any way to solve this without renaming one of the methods? Below the stripped down version of main.cpp that doesn't compile. Thanks!

type; };

type; };

Hi again,

Hi,
I am trying to set up a multi_index_container-type with a template argument like this:
template <typename event_type> struct mi_container { typedef typename mi::composite_key< event_type, mi::const_mem_fun<fields::field_ts, ts_type, &fields::field_ts::ts>, mi::const_mem_fun<fields::field_addr, addr_type, &fields::field_addr::addr>, mi::const_mem_fun<fields::field_port, port_type, &fields::field_port::port>
self_key_type; [...] };
mi_container<ev_connect>::type connected;
This gives me the following compile-error:
main.cpp: In instantiation of [...] event::fields::field_ts::ts to form a pointer-to-member-function main.cpp:75: note: a qualified-id is required
Probably I doing something silly. Note that if I remove the class template and directly specialize it, there is no problem at all. Can anybody help me out?
Ummm... Can you provide more context? Where and how is fields defined, and what its relationship is wrt to event_type?
Thank you,
