I am using Linux Fedora 20. In order to compile C programs for the Arduino, as described in the book "C Programming with Arduino" by Warwick A Smith, pub by Elektor, I have downloaded and untarred/unzipped "avr8-gnu-toolchain-220.127.116.111-linux.any.x86.tar.gz". That's as far as I can get. Please how do I proceed from this point? Is there anything else I need or should have done?
