hi
I have a problem with CPU mining
I tried with Minerd-yacoin_stratum_x64_2_4_0
but I had only 30 hash / s !!
there is another method or another CPU mining software that gives a bit more?
thank you very much

That codebase appears to lack the optimizations that Mikaelh added that are included in the yacoin cpu miner, so it would be 5-10% slower no matter what.
The best answer would be to use the binary in the package on my github that have the CPU instructions your CPU supports - there is a text file to give some examples, but try the avx, avx-i, and avx2 ones if you have a modern intel processor. If it doesn't work, try a different one.
Edit - after reading the rest of the thread, if you simply keep posting "it doesn't work" instead of providing useful error messages, nobody is going to be able to help you.
