Re: [Boost-users] Conversions between shared_ptr<Base> and shared_ptr<Derived>

So I have something like this:

std::vector<boost::shared_ptr<Base> > BaseVector;

void add(boost::shared_ptr<Base>& newOne) { BaseVector.push_back(newOne); }

and I call it like this usually : boost::shared_ptr<Derived> p(new Derived); add(p);

I think the problem is you take a reference to the shared_ptr. Try this way:

void add(boost::shared_ptr<Base> newOne) { BaseVector.push_back(newOne); }

Ah, that seemed to have fixed the problem. Thank you, Joshua.
