What miner do you have there ?
Is it maybe a bitcoin miner -sha256 asic- and you try to mine scrypt with it ?
Nah... they're Zeusminers... I mine DGB using the normal P2 and standard pools.... just stopped for a bit while the algo gets sorted out so I'm selling Scrypt on Nicehash for the moment.
@ Digibyte, as I PM'd I had no issues compiling on Debian, but I'll build another VM with Ubuntu and do a comparison. What version are you using yourselves? I prefer headless SSH only... but can use a GUI too if need be.
