just to add to my post from the 19th Feb:
then when I run “Attract” it says:
Starting Attract-Mode v2.0.0 (Linux)
Config file not found: /home/pi/.attract/attract.cfg, performing initial setup.
Failed to open X11 display; make sure the DISPLAY environment variable is set correctly
Aborted
I have tried compiling on both Wheezy and Jessie and yet I get the same errors.
