errors while using cache filter in message_filters

edit

I am trying to access historical data generated by lidar over multiple frames. Based on some suggestion, I was trying to use cache filter to solve it. Eventually, got lot of errors and could not figure out the particular error source. Following is the code;

message_filters::Cache<sensor_msgs::PointCloud2> cache;
    void pcl_history_caller(const sensor_msgs::PointCloud2::ConstPtr &cloud_data)
    {
      cache.add(cloud_data);
      std::vector<sensor_msgs::PointCloud2::ConstPtr> interval_1 = cache.getInterval(cache.getOldestTime(), cache.getLatestTime());
    // do some stuff here using  cache here

    }

    int main(int argc, char** argv)
    {
        ros::init(argc, argv, "cache_node");
        ros::NodeHandle nh;
        message_filters::Subscriber<sensor_msgs::PointCloud2> pcl_history(nh, "hokuyo_points", 1);
        cache(pcl_history, 100);
        cache.registerCallback((boost::bind(&pcl_history_caller), _1));


 ros::spin();
    return 0;
}
`

Following are the errors;
