Dear I use Pi 3 B, I had run my code with pi4j for along but I got this error for today. I think I missing something.

@chhaysereiseth

Starting on 2018-04-23, the 1.2-SNAPSHOT builds no longer statically links to the WiringPi dependency and you must have WiringPi installed on your system separately from Pi4J.

sudo apt-get install wiringPi

Or build and install from source: http://wiringpi.com/download-and-install/

This is part of the effort to support the new RPi3B+ and in accordance with the changes requested by WiringPi.

Thank you so much.

Note that the command sudo apt-get install wiringPi does not work, because the package name is spelled with a lower-case p:

sudo apt-get install wiringpi
