Question

I´m new to c++. i´m getting an error “Symbol ‘List’ could not be resolved”
I´m working on eclipse i can´t figure out what is the problem…

List.h here is the declaration of the father class which is a generic class, which Vector
will inherit

#ifndef LIST_H_
#define LIST_H_

template <class E> class List {
protected:
    int size;

public:
    virtual ~List();
    virtual void add(E o) = 0;
    virtual E get(int index) = 0;
    int getSize();
};

template <class E> List<E>::~List() {
}

template <class E> int List<E>::getSize() {
    return size;
}

#endif /* LIST_H_ */

Vector.h Vector header file, which inherits from List, and it will implement the pure virtual methods of List
im getting the error, when i inherit from List, in the class declaration of Vector, “Symbol ‘List’ could not be resolved”

#include "List.h"
template <class E> class Vector: public List<E>{
private:
    class Node {
    public:
        E value;
        Node* next;
        Node(E value): value(value), next(0) {}
    };

    typedef Node* PNode;
    PNode first;

public:
    Vector();
    virtual ~Vector();
    void add(E o);
    E get(int index);
    virtual void add(E o);
    virtual E get(int index);
};

Quick search on google yelds that Symbol ‘List’ could not be resolved is not a compilation error, it’s (stupid) eclipse is trying to rebuild a cross reference for you. Try a menu command Index->Rebuild.
