I'm using Ubuntu 12.04 + ROS Fuerte + pcl and ros_pcl packages. When I try to use an object of the class PointCloudColorHandlerCustom, belonging to the pcl library (1.5) included in ROS, I have an error.

The code is the following:

pcl::visualization::PointCloudColorHandlerCustom<pcl::PointXYZ> blue_color (particle_cloud, 250, 99, 71);

and the error is:

The type 'pcl::visualization::PointCloudColorHandlerCustom' must implement the inherited pure virtual method 'pcl::visualization::PointCloudColorHandler::getColor' 

P.S. I'm trying to port under ROS the openni_tracking example.
