Hi, I'm having problem compiling this piece of code in VC++ 7.1. I don't know if it is a bug in this environment but it compiles properly under gcc 3.4.4. thanks for any help !!! #include <boost/signal.hpp> #include <boost/bind.hpp> boost::signal<void (int)> m_signal; struct Foo { void test(int x) {} }; template <typename C> boost::signals::connection Subscribe(C* ptr,void (C::*callback)(int)) { return m_signal.connect(boost::bind(callback,ptr,_1)); } int main() { Foo f; Subscribe(&f, &Foo::test); return 0; } Here are the compiler errors: c:\Program Files\boost\boost_1_34_1\boost\visit_each.hpp(25) : warning C4675: 'void boost::_bi::visit_each<Visitor,void,boost::_mfi::mf1<R,T,A1>,boost::_bi::list2<boost::_bi::list_av_2<C *,A2>::B1,A2>>(V &,const boost::_bi::bind_t<R,F,L> &,int)' : resolved overload was found by argument-dependent lookup with [ Visitor=boost::signals::detail::bound_objects_visitor, R=void, T=Foo, A1=int, C=Foo, A2=boost::arg<1>, V=boost::signals::detail::bound_objects_visitor, F=boost::_mfi::mf1<void,Foo,int>, L=boost::_bi::list2<boost::_bi::list_av_2<Foo *,boost::arg<1>>::B1,boost::_bi::list_av_2<Foo *,boost::arg<1>>::B2> ] c:\Program Files\boost\boost_1_34_1\boost\bind.hpp(1173) : see declaration of 'boost::_bi::visit_each' c:\Program Files\boost\boost_1_34_1\boost\signals\slot.hpp(123) : see reference to function template instantiation 'void boost::visit_each<boost::signals::detail::bound_objects_visitor,F>(Visitor &,const T &)' being compiled with [ F=boost::_bi::bind_t<void,boost::_mfi::mf1<void,Foo,int>,boost::_bi::list2<boost::_bi::list_av_2<Foo *,boost::arg<1>>::B1,boost::_bi::list_av_2<Foo *,boost::arg<1>>::B2>>, Visitor=boost::signals::detail::bound_objects_visitor, T=boost::_bi::bind_t<void,boost::_mfi::mf1<void,Foo,int>,boost::_bi::list2<boost::_bi::list_av_2<Foo *,boost::arg<1>>::B1,boost::_bi::list_av_2<Foo *,boost::arg<1>>::B2>> ] c:\Documents and Settings\mbrodeur\My Documents\Visual Studio Projects\testboost\testboost\testboost.cpp(16) : see reference to function template instantiation 'boost::slot<SlotFunction>::slot<boost::_bi::bind_t<R,F,L>>(const boost::_bi::bind_t<R,F,L> &)' being compiled with [ SlotFunction=boost::signal1<boost::detail::function_traits_helper<boost::add_pointer<void (int)>::type>::result_type,boost::detail::function_traits_helper<boost::add_pointer<void (int)>::type>::arg1_type,boost::last_value<void>,int,std::less<int>,boost::function<void (int)>>::slot_function_type, R=void, F=boost::_mfi::mf1<void,Foo,int>, L=boost::_bi::list2<boost::_bi::list_av_2<Foo *,boost::arg<1>>::B1,boost::_bi::list_av_2<Foo *,boost::arg<1>>::B2> ] c:\Documents and Settings\mbrodeur\My Documents\Visual Studio Projects\testboost\testboost\testboost.cpp(22) : see reference to function template instantiation 'boost::signals::connection Subscribe<Foo>(C *,void (__thiscall Foo::* )(int))' being compiled with [ C=Foo ] thanks ! -- View this message in context: http://www.nabble.com/1.34.1%3A-boost-bind-issue-with-function-template-tp19...
