It’s hard to make sense of your pull request. This is the only error I found:

– SHA256_CTX ctx_fsha256;
+ SHA256_CTX ctxf_sha256;

The non-SHA code works for me on 6700K, can you confirm it works on Ryzen?

Edit: ok I found 2 more bugs, one a run time that would break the hash.

> SHA256_Update( &ctxf_sha256, bdata_p64, bytes );

Do you still get rejects with these fixed?

Yes, all the others I’ve tried so far (except sha256t) work on Ryzen. The changes I made are here: https://github.com/JayDDee/cpuminer-opt/pull/8/files

Edit: I still get the rejects after those changes. I haven’t really dug into it outside of getting it to compile but those changes should have gotten it to work.

Yes, non-sha compiles perfectly.

You could remove the __SHA__ check and compile it with openssl sha256 instead of sph_256. It’ll still run on other hardware just not accelerated.

I was able to mine with a Ryzen 1700X using v3.6.1 on the Xevan algorithm. It worked quite well based on my limited experience with CPU mining. I ran it for 13 1/2 hours and had only 1 rejected share out of 2003 total.

Did you build it from source?

I should have done that before releasing. M7m fails for me using openssl. I have something to work with now.

Excellent! I’m afraid figuring that one out might be far beyond my knowledge.

No I have not been able to figure out how to compile it myself, I used a pre-compiled version from a helpful person via youtube.
