Dotaz: pretizeny operator sablony a gcc 3.4.2

[Pavel Stupka]

Zdravim, mam takovej trochu vetsi problem. V nove verzi GCC (3.4.2) mi nejde prelozit tento zdrojak:
template < typename T> class vect {
......
friend ostream& operator<< <>(ostream&, const vect< T>&);
......
};

template < typename T>
ostream& operator<< (ostream& out, const vect< T> & pol) {
.....
}
//---------------------------------------------------------------------------------------------
Chyba je nasledujici: error: template-id `operator>>< >' for `std::basic_istream< char, std::char_traits< char> >& operator>>(std::basic_istream< char, std::char_traits< char> >&, polynom< double>&)' does not match any template declaration *** Error code 1 (bu21) Nevite nekdo jak to udelat? .... ve starsich verzich < 3.4.2 to slo v pohode bez jedineho varovneho hlaseni

Friend declarations that refer to template specializations are rejected if the template has not already been declared. For example,

	template <typename T>
	class C {
	  friend void f<> (C&);
	};

is rejected. You must first declare f as a template,

	template <typename T>
	void f(T);
