Re: [Boost-users] [bind+signals] binding overloaded function + gcc4.6.2 = call of overloaded is ambiguous

Hi all, Such code can be built without problem using gcc3.4.3:

typedef boost::signal< void () > Signal; Signal s; boost::bind( &Signal::operator(), &s );

but gcc4.6.2 returns:

error: call of overloaded 'bind(<unresolved overloaded function type>, Signal*)' is ambiguous

Is it expected behaviour? or problem in gcc4.6.2? Is there any solution except casting function pointer to particular type?

You could use boost::bind(boost::apply<void>(), boost::ref(s));
