I created a cpuminer instance for my Raspberry Pi derived from this tutorial. Apparently, I've correctly configured the implementation because I can run the example provided in the README:
./cpuminer -u alexanderjsingleton.Pericles -p pass -o stratum+tcp://stratum.slushpool.com:3333 -t cputhreads
Apparently, that command is indeed the example because I'm not seeing any feedback displayed within my slushpool-account dashboard for that worker. However, according to this StackExchange:Bitcoin post, the appropriate cpuminer-syntax should be:
./minerd -u alexanderjsingleton.Pericles -p pass -o stratum+tcp://stratum.slushpool.com:3333 -t cputhreads
but that command returns the following error:
./minerd -h --algo scrypt --scantime 33 --url stratum+tcp://stratum.slushpool.com:3333 --userpass [alexanderjsingleton.Pericles]:[password] --threads 1 --retries -1 -P -bash: ./minerd: No such file or directory
In any case, this is my first experiment with actual Bitcoin-mining, so I'd appreciate any guidance whatsoever to start mining on my first block- thank you!
