I think it complains the class has no constructor other than the copy one.
you should try to add one :
class MyClass {
public:
MyClass(AnotherClass *p); // constructor
MyClass(const MyClass &mc); // copy constructor
private:
AnotherClass* const ptrToAnotherClass;
}
MyClass::MyClass(AnotherClass *p) :
ptrToAnotherClass(p)
{
// other assignments
}
