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.
