Hello, I'm trying to run the PCL tutorial programs (cturtle alpha 5 on Ubuntu 10.04) but I get a missing library error as follows: $ rosrun pcl tutorial_surface_convex_hull /opt/ros/cturtle/stacks/point_cloud_perception/pcl/bin/tutorial_surface_convex_hull: error while loading shared libraries: libhdf5_cpp-1.6.6.so.0: cannot open shared object file: No such file or directory I have libhdf5-serial-dev installed, and there exists a libhdf5_cpp.so.6 on my system (in /usr/lib), but not the file mentioned in the error message. I can't see where that particular file would be specified in the PCL tutorial code. Does anyone have experience running these tutorials on this platform? Seems like I must have something misconfigured, but I'm not sure what, so any suggestions are most welcome! Mike
