Where is a good program for mining ETH Using the CPU?

#1
I have been trying for over a week to get geth to run on my system, but can't seem to find a good program to run. I am trying this on a amd 64 system with 3.5 ghz processor and 4 gig of ram, I am running the ubuntu artful 17.10 os. Any one got any suggestions? Please?!!
Thanks
