Sorry - I missed the error message out last time:
Hi,
I've got a linkedlist system done with a triplet of classes, lets
call them:
ll_element
ll
ll_iter
ll keeps its list of ll_elements and I want all the functions in 'll'
to be friendly with ll_element so that ll methods can get to the next
pointer in ll_element.
I used to (gcc2.7.2.x) do:
template<class content> ll_element {
friend ll<content>;
friend ll_iter<content>;
}
and all was OK. But now if I do that I get:
LinkedList.h:44: `' is neither function nor method; cannot be declared friend
The line number is the line with the 'friend' statement on.
Is this a fix for an old over-liberalism or is it a new bug (the error
definitly looks dodgy)?
I can't seem to do it by tons of:
friend ll<content>::add();
lines because it complanes that I'm declaring a friend before the
class ll<content> is defined.
Suggestions?
Dave
P.S. Besides just being interested in egcs I'm trying this now
because GCC is failing with an internal error on a piece of my code.
