Question

I am getting an error I do not understand. There was even a similar question asked on SO that I found, but the fix given is already in my code.

I am getting an error in this line:

ForestNode<NODETYPE> foo = new ForestNode<NODETYPE> ForestNode(bar);

that reads :

\project 4\forest.h|85|error: expected ‘,’ or ‘;’ before ‘ForestNode’

My class forestnode is defindes as such:

template<typename NODETYPE> class Forest;

template<typename NODETYPE> class ForestNode
{
    friend class Forest<NODETYPE>;

    public:
        ForestNode( const NODETYPE &);
        ~ForestNode();
        NODETYPE getTag() const;
    private:
        NODETYPE tag;
        ForestNode<NODETYPE> *leftChild;
        ForestNode<NODETYPE> *sibling;
};

Any ideas?

You have the type name twice in the constructor call, try:

ForestNode<NODETYPE> foo = new ForestNode<NODETYPE>(bar);
