Ah. So to fix that, you need to download the libstdc++.so.6 in the ntcore folder. Place that in /home/pi/ on your Pi, and add this line to your program start command.

env LD_PRELOAD=/home/pi/libstdc++.so.6 . So your command to run would become env LD_PRELOAD=/home/pi/libstdc++.so.6 java myapp.jar, replacing myapp.jar with whatever your app is.
