You need to set the "LD_LIBRARY_PATH" environment variable to have the directory you put the ntcore libraries. You can do this either by the method on the wiki:
Code:
$ env LD_LIBRARY_PATH=/home/pi/vision/grip:$LD_LIBRARY_PATH java -jar ...
or by setting it in the .bashrc file in your home directory by adding this line:
Code:
export LD_LIBRARY_PATH=/home/pi/vision/grip:$LD_LIBRARY_PATH
You can edit this file with "$ nano ~/.bashrc".
