# Headless install of cgminer on a ATI HD series GPU
# Tested on Ubuntu server 12.04.4 with a ATI HD 7970
#
# Do a regular install of Ubuntu server with openssh enabled.
# Then run this script.
#
# The script requires a REBOOT, which could be avoided,
# but I haven't had a chance to test it
#
# The script does everything from scratch, eveerytime you run it.
# ie the $HOME/mine/ directory is deleted/recreated on every run.
# To avoid this, run relevant sections manually if needed.

# not updating repo metadata is the cause of many woes:

rm -f AMD-APP*tgz   # You can comment/delete this, and the following line, to avoid re-download, if you only want to run certain sections of the script.

# y u not provide normal HTTP/FTP links AMD?
# I'm sure someone has the regular HTTP GET or FTP links, but I can't find them.
# These curl commands are fragile are sure to stop working sometime.
# EDIT stopped working. Do a manual download
