Hi ROS-Users, I am new to ROS. I got our labs Hokuyo-scanner to work with ROS within minutes but got stuck with problems while trying to use a Swissranger 4k. The problem is that I don't find a way to include external libs, namely ANN, FLANN and cminpack which are required by point_cloud_mapping. Could someone give me a hint about the basics... Do I have to create a package manually and fill in the sources from the downloaded ANN/FLANN archives? Where is rosmake searching for the built libs? Or did I miss something and rosdep is able to install this stuff automatically? Has perhaps someone used the swissranger-driver-wrapper from Radu Bogdan Rusu? It uses messages from deprecated-msgs that I replaced by sensor_msgs. But it needs the mentioned external packages. I would of course contribute the updated driver, if I get it to work. Perhaps this toppic was already discussed here, but the search functionality of the archive at https://code.ros.org/discuss/ros-users/ seems to be broken (?). Also the link on the Thanks, Andreas
