C++ compilation problems

satchmo

I have two classes (ObjectList and ObjectNode) which both refer to each other (ie ObjectList contains an ObjectNode pointer and vice versa). However when I try to compile the program I can't get these two classes to compile because they're both looking for each other (I think).

Am I [not] doing something stupid?

Why does your ObjectNode refer to ObjectList?
Is it a linked list you're writing?
What you need to do is make a forward declaration of the classes:

//forward declaration of ObjectNode
class ObjectNode;

class ObjectList{
public:
blah blah blah

};

If you are make a linked list, you shouldn't have to refer to ObjectList in the ObjectNode class.

Well it's a linked list, but every node contains a sub-list of nodes, sort of a tree.

I put in forward declarations of the other class in both header files which seems to have cleared up a lot of errors, but now the problem is that even with the declarations, when any methods in those classes are called they're not known.

I had an inlined function in the header which was calling a function of the other class, so I removed this and put it in the .cpp file and now it's compiling fine

Nice one Draco, thanks alot.
