[boost] constructor in singleton?

I'm a little confused about singleton usage.  Can a singleton have a
constructor?

I tried this:

using boost::basic_singleton;

struct Example :
  public basic_singleton<Example> {
  Example() {
    std::cout << "Hello\n";
  }
  int Cnt() const { return 0; }
};

int main() {
  Example::pointer ptr;
  std::cout << ptr->Cnt();
}

./Test1
0

It appears constructor wasn't run, because nothing was printed.
