-P for what?
I'm using wallet in one pc with windows and then starting cpuminer compiled on my linux server with this:
./minerd -a heavy -o
http://mywindowspcip:7202 -u myusername -p mypwd -v 1024
What's wrong with this?
That's okay. minerd:
-P, --protocol-dump verbose dump of protocol-level activities
can be useful in debugging errors.
