Change the type of the left side then ;-). Try taking away the constantness, like: ItemList::reverse_iterator anchor = _items.rbegin(); Supposedly the STL should define both "const reverse_iterator begin()" and "reverse_iterator begin()", but is hard from the compiler point of view to tell the difference or compose the right combination of consts inside a template code (the resulting assembler code is identical, these distinctions are meant to "help" us, programmers ;-). > > Check also if your compiler doesn't have a flag to relax a bit the > > type convertion rules, Solaris' compiler seems tighter than gcc (what > > doesn't mean it's better or worse, just different! ;-) > > Solaris' compiler is extremely anal, as is IRIX's MIPSpro and VMS's DEC C. Yeah, each in its own way! :-) This is why I love script languages so much! Carlos -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
