ros::NodeHandle& private_nh = getPrivateNodeHandle();
ros::NodeHandle& nh = getNodeHandle();
There are just local variables, that only exist within onInit(). You need to declare them in your class declaration and set them in this function. Something like this:
class OD
{
....
ros::NodeHandle private_nh;
ros::NodeHandle nh;
void onInit()
{
...
private_nh = getPrivateNodeHandle();
nh = getNodeHandle();
}
}
