Linux says I don't have AES but my CPU does #185

Closed FoxyBit closed 5 years ago

FoxyBit commented 5 years ago

I have successfully downloaded and compiled cpuminer, but when I run it I get the message:

Only CPUs with AES are supported, use legacy version.

However I have a A10-7700K CPU which does indeed have AES support. How can I get this to work? Is there something else that's not in the INSTALL_LINUX instructions I can use to get it working? TIA

I assume you're trying to mine hodl, all the others can run without AES.

This message means cpuminer wasn't built with AES. If you used build.sh the compiler built for the "native" architecture meaning the compiler chooses what featurtes to enable. Maybe a problem with the compiler, AMD users have long complained about compiling with the correct features, although not so much recently. Maybe you have an old compiler and the newer ones work better. Or maybe it's a problem with feature detection on yor CPU.

You can force he compiler to use AES. Instead of using build.sh with its defaults run this before make:

CFLAGS="-O3 -maes -mavx -Wall" ./configure --with-curl

Please report your results including posting the cpuminer startup messages. It will tell us where the problem is. If it runs ok it's a compiler problem. If cpuminer can't detect AES either it's a CPU problem. And if it crashes then the compiler was right even though the specs say your CPU has AES and cpuminer passed its AES check.

Good catch dooglz. I was doing some clean up and forgot to complete the double polarity reversal. Will be fixed in next release, use v3.8.8.1 for now.

Hi JayDDee

When using your latest version for mining roi/hodl on my westmere cpu, I get the following error:

Coming back to ver 3.8.8.1 (freshly built) gives me zero problem:

Is westmere cpu no longer supported? Should I stick to 3.8.8.1?

Thanks in advance.

JayDDee commented 5 years ago

This is a different issue, you're not getting the error message, cpuminer is crashing.

I've reproduced it with a aes-sse42 build even though the CPU is Ryzen. Native Ryzen build works so it's a problem with the aes-sse42 build.

I will investigate. In the meantime use what works for you.

JayDDee commented 5 years ago

Fixed in v3.9.5.3, and faster than v3.8.8.1 on Westmere.

vladilog commented 5 years ago

Yes. I confirm v3.9.5.3 is working. Thanks a lot !
