c4512 warning using signals2 with boost 1.41 on VS2005

[Lonnie Mask <allthingscode@…>]

I am using the signals2 library, and I get the following warnings with VS2005:

Warning 1 warning C4512: 'boost::signals2::detail::signal1_impl<R,T1,Combiner,Group,GroupCompare,SlotFunction,ExtendedSlotFunction,Mutex>::slot_invoker' : assignment operator could not be generated c:\boost\boost_1_41_0\boost\signals2\detail\signal_template.hpp 358

Warning 2 warning C4512: 'boost::signals2::detail::slot_call_iterator_cache<ResultType,Function>' : assignment operator could not be generated c:\boost\boost_1_41_0\boost\signals2\detail\slot_call_iterator.hpp 44

Warning 3 warning C4512: 'boost::signals2::detail::signal1_impl<R,T1,Combiner,Group,GroupCompare,SlotFunction,ExtendedSlotFunction,Mutex>::invocation_janitor' : assignment operator could not be generated c:\boost\boost_1_41_0\boost\signals2\detail\signal_template.hpp 412

Warning 4 warning C4512: 'boost::function_output_iterator<UnaryFunction>::output_proxy' : assignment operator could not be generated c:\boost\boost_1_41_0\boost\function_output_iterator.hpp 40

I have my warning level set to 4.

Your compiler is generating spurious warnings. Those classes (excluding the last one which is not part of signals2 and I don't know about) don't need assignment operators. Feel free to open another ticket with a patch that silences the warnings if they bother you (perhaps by declaring private assignment operators in the classes?).

It's two years and 7 versions later, and I'm still encountering this guys problem.

Good work Boost.

Same here. Still encountering these.

Turning the warning level down will silence them! Hope this helps.
