I believe I am following your instructions properly, this is the command I am running to launch my jar:

env LD_PRELOAD=/home/pi/libstdc++.so.6 java -jar ntcoreblah.jar

But I still get the error. Is my syntax wrong? Is there yet another dependency that I need to preload? Is there something I need to install on my Pi in order for that environment variable to take effect?

Thank you so much for continuing to reply and not giving up on me!
