PI4J - 无法使用路径加载 [libpi4j.so]

Question

我在 MacOS 上使用 NetBeans 来开发使用 PI4J 的应用程序。一切看起来都不错，但我收到以下错误，指出 PI4J 无法加载。有谁知道如何解决这个问题？

Answer 1

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

这是取自 pi4j 我遇到了这个问题，当我在终端中执行这些行时......一切都很完美
