Hi. I'm running Ubuntu 16.04 and ROS Kinetic. I recently upgraded from 14.04 and Indigo. Everything worked fine before, but now, when I try to launch my Kinova Jaco arms, I'm getting an error and I don't understand how to fix it. I've never gotten an error like this before, and I tried googling but I can't seem to find out what to do to fix this. Any help you can provide would be very greatly appreciated! Thanks very much!

The command I run :

roslaunch kinova_bringup kinova_robot.launch kinova_robotType:=j2n6s300 kinova_robotName:=left kinova_robotSerial:=PJ00900006WO5044820

The Error I get

As to your problem: have you rebuilt the workspace after upgrading (ie: remove the build and devel folders and run catkin_make (or catkin build) again)?

Looking at the readme it appears things should-just-work on Kinetic.

The is a library that is distributed with kinova_driver (here) and installed here.

There don't appear to be any specific build or installation instructions, so I assume it should work in both the devel as well as the install space.

The error essentially tells you that the search path for libraries does not include the location that holds the .so file(s).

Yes, I did rebuild the workspace after upgrading

It seemed there were multiple issues. First, for some reason the library you showed me was missing in my folder. I ended up re-installing kinova-ros completely to ensure there weren't any other things missing. That fixed some problems but not all. Then, I eliminated any specifications of the arm (name, serial number) and I was finally able to bring up one arm. Then when I tried again to bringup a specific arm using the name and serial number it all of a sudden worked. Strange. But thank you very much for your help in solving this issue.
