the warning is pointing at the wrong spot, it's yelling about a declaration,
and pointing at the call in main
> warning: friend declaration `std::ostream&
>opacki::operator<<(std::ostream&, const opacki::List<ItemType>&)'
> declares a non-template function
note: friend 'declaration'
the problem is probably in class declaration
most likely:
>friend ostream& operator <<(ostream& outs, const List<ItemType>& theList);
involving the 'friend ostream&'
that is all I have found
as a guess: there is no template for a friend declaration in this context
if anyone else can find more, please let me know
if I'm chasing a wild goose, please let me know
