[FIXED] PI4J - Unable to load [libpi4j.so] using path

Issue

I'm using NetBeans on MacOS to develop an application using PI4J. Everything looks Ok but I get the error below, saying that PI4J was unable to load. Does anyone know how to solve this?

Solution

sudo apt-get remove wiringpi -y
sudo apt-get --yes install git-core gcc make
cd ~
git clone https://github.com/WiringPi/WiringPi --branch master --single-branch wiringpi
cd ~/wiringpi
sudo ./build

This is taken from pi4j I faced this issue and when I executed these lines in terminal...everything worked perfectly
