[Mingw-users] Overloading the istream operator for template class fails

[Patrick L. <pat...@ho...>]

I am experiencing a problem when I try to overload the
ostream and istream operators for a template class.
I have tried to search for information on the internet
and it seems like this will not be possible.  However, I
would like to know if you think this is possible or not.

Kind regards,
Patrick


My class looks like: (Shortened of course)

---------CODE SNIPPET START----------
template 
class Stack
{
    public:
        friend istream& operator>> (ostream& istream, const Stack& stack);
};

template 
friend istream& operator>> (ostream& istream, const Stack& stack)
{
    return istream;
}
---------CODE SNIPPET END----------



And then I get the following errors.

---------COMPILE ERROR START----------

..\stack.h:45: warning: friend declaration `std::istream& operator>>(std::ostream&, const Stack&)' declares a non-template function
..\stack.h:45: warning: (if this is not what you intended, make sure the function template has already been declared and add <> after the function name here) -Wno-non-template-friend disables this warning
..\stack.h:111: error: can't initialize friend function `operator>>'
..\stack.h:111: error: friend declaration not in class definition
---------COMPILE ERROR END----------
