'class' : class has no constructors

The class, structure, or union has no constructor with a parameter list that matches the parameters being used to instantiate it.

A class must be fully declared before it can be instantiated.

The following sample generates C2514:

// C2514.cpp  
// compile with: /c  
class f;  
  
class g {  
public:  
    g (int x);  
};  
  
class fmaker {  
   f *func1() {  
      return new f(2);   // C2514  
   }  
  
   g *func2() {  
      return new g(2);   // OK  
   }  
};
