help with aurora library

[Mortal]

i tried to use aurora lib just to understand it. however when i compiled the example in its official site i got errors. i don't know why this happened.

the code in official site:

#include <Aurora/Dispatch.hpp>
#include <iostream>

struct Object { virtual ~Object() {} };
struct Asteroid : Object {};
struct Ship : Object {};

void collisionAA(Asteroid*, Asteroid*) { std::cout << "Asteroid-Asteroid\n"; }
void collisionAS(Asteroid*, Ship*)     { std::cout << "Asteroid-Ship\n"; }
void collisionSS(Ship*, Ship*)     { std::cout << "Ship-Ship\n"; }


int main()
{
        // Register "overloaded" functions
        using aurora::Type;
        aurora::DoubleDispatcher<Object*> disp;
        disp.bind(Type<Asteroid>(), Type<Asteroid>(), &collisionAA);
        disp.bind(Type<Asteroid>(), Type<Ship>(), &collisionAS);
        disp.bind(Type<Ship>(), Type<Ship>(), &collisionSS);

        // Call function, given only base class pointers
        Asteroid a;  
        Object* pa = &a;
        Ship s;      
        Object* ps = &s;
        disp.call(pa, ps); // Output: Asteroid-Ship
        std::cin.ignore();
}

errors appear like this:

i'm using VS 2013. how to solve those errors?

This API has changed in the meantime, I just forgot to update the examples

Should be good now!

#include <Aurora/Dispatch.hpp>
#include <iostream>

struct Object { virtual ~Object() {} };
struct Asteroid : Object {};
struct Ship : Object {};

void collisionAA(Asteroid*, Asteroid*) { std::cout << "Asteroid-Asteroid\n"; }
void collisionAS(Asteroid*, Ship*)     { std::cout << "Asteroid-Ship\n"; }
void collisionSS(Ship*, Ship*)     { std::cout << "Ship-Ship\n"; }

int main(){
        // Register "overloaded" functions
        using aurora::Type;
        aurora::DoubleDispatcher<void(Object*, Object*)> disp;
        disp.bind(Type<Asteroid>(), Type<Asteroid>(), &collisionAA);
        disp.bind(Type<Asteroid>(), Type<Ship>(), &collisionAS);
        disp.bind(Type<Ship>(), Type<Ship>(), &collisionSS);

        // Call function, given only base class pointers
        Asteroid a;   Object* pa = &a;
        Ship s;       Object* ps = &s;
        disp.call(pa, ps); // Output: Asteroid-Ship
}
