I'm following this tutorial to set up Ubuntu mining on Ubuntu 12.10 32 bit. https://docs.google.com/document/d/1Gw7YPYgMgNNU42skibULbJJUx_suP_CpjSEdSi8_z9U/preview?sle=true
At last step they suggesting to check out settings with ./cgminer -n. I've got this
kirill@kirill-desktop:~/cgminer-2.11.4-x86_64-built$ ./cgminer -n bash: ./cgminer: cannot execute binary file
What's wrong with me?
