Hi, I'm trying to use thew BLL for the first time and I've the following program: class Date { public: Date(long d): _lDate(d) {} long getDate() const { return _lDate; } [...] private: long _lDate; }; std::ostream& operator<<(std::ostream &s, const Date &x) { [...] } struct C { C(long d): date(d) {} Date date; }; int main() { const C c(46000); std::cout << boost::bind(&C::date, boost::lambda::_1)(c) << std::endl; std::vector<C> cont(1, C(46000)); std::for_each(cont.begin(), cont.end(), std::cout << boost::bind(&C::date, boost::lambda::_1)); return 0; } The first std::cout is ok. But for the second one nested int the for_each I get this message error: error C2679: binary '<<' : no operator found which takes a right-hand operand of type 'boost::_bi::bind_t<R,F,L>' (or there is no acceptable conversion) with [ R=const Date &, F=boost::_mfi::dm<Date,C>, L=boost::_bi::list1<boost::arg<1>> ] C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\INCLUDE\ostream(653): could be 'std::basic_ostream<_Elem,_Traits> &std::operator <<<char,std::char_traits<char>>(std::basic_ostream<_Elem,_Traits> &,const char *)' [found using argument-dependent lookup] with [ _Elem=char, _Traits=std::char_traits<char> ] Can you help me? Thank you, Mirko **
