Subscriber with member callback function

edit

I am trying to subscribe to the model msgs in gazebo, however I cannot bind the callback function in a correct way. This is the code:

class WorldInterface : public WorldPlugin

{

public:


    void messageReceived1(const msgs::Model& _msg)
    {
        std::cout << "Got the message!" << std::endl;
        modelLoaded_ = true;
    }

    void Load(physics::WorldPtr _parent, sdf::ElementPtr _sdf)
    {

        transport::NodePtr node(new transport::Node());
        node->Init();


        transport::SubscriberPtr modelSub =
                node->Subscribe("~/model/info", std::bind(&gazebo::WorldInterface::messageReceived1, this, _1));

.....
}
};

The error I get is:

error: no matching function for call to ‘gazebo::transport::Node::Subscribe(const char [13], std::_Bind_helper<false, void (gazebo::WorldInterface::*)(const gazebo::msgs::Model&), gazebo::WorldInterface*, boost::arg<1>&>::type)’
     node->Subscribe("~/model/info", std::bind(&gazebo::WorldInterface::messageReceived1, this, _1));
