C++: Overriding a protected method which is called by another method

I have a very basic question concerning inheritance in C++:

class A
{
public:
  void foo() { print(); }
protected:
  void print() {}
};

class B : public A
{
protected:
  void print() { std::cout << "test" << std:: endl; }
};

Now the following code

B b;
b.foo();

doesn't print anything, so foo() obviously didn't call the newly defined print(). Is this only solvable by using virtual methods?
