I'm guessing it's because I've written this incorrectly, but I'm not sure what to look up in order to figure out what's wrong.

undefined reference to `vtable for Entity' on line 13

Entity::Entity(std::string sName="Unnamed", sf::Vector2f v2fPos=sf::Vector2f(0,0))
    : name(sName), pos(v2fPos) // error occurs here.
{
    if (DEBUG)
        std::cout << "Constructing " << typeid(*this).name() << std::endl;

    // etc....
}

    protected:

};

Thanks for the help!
