Hi - this library is ROS independent. Please, take a look and try to run the script demo.sh to find out, if the problem is related to the library or the ROS implementation. From this error output I can not tell anything.

I think my issue is that my cmake could not find the module config file for but_velodyne_lib. Quick question, how do you let cmake look for the but_velodyne_lib module config file, suppose I have compiled the but_velodyne_lib at my home directory? Thanks a lot.

This is what I get after I entered backtrace on gdb:
