you missed part on page linked to:
if using ubuntu can use ubuntu packages our launchpad ppa. install: $ sudo add-apt-repository ppa:gijzelaar/snap7 $ sudo apt-get update $ sudo apt-get install libsnap71 libsnap7-dev execute 3 commands in order , should fine. however, software older system, need edit /etc/apt/sources.d file created after first step , replace xenial (or yaketty) trusty. ppa has builds older releases.
