Won't build on armv7

[weboide]

On a beaglebone black: Linux bbb 4.4.59-ti-r96 #1 SMP Tue Apr 4 17:50:34 UTC 2017 armv7l armv7l armv7l GNU/Linux

With a clone of the master branch, this is what I get:

$ make install

Removing the sse2 and aes options, this is what I get:

Hi, unfortunately the CPU version is SSE2 optimised and won't work without it. We have a more flexible hashing selection algorithm now, so ARM build is possible by lifting the code from monero-core. Do you feel like testing that =)?

[weboide]

I'm using monerod from monero-core to run a node on the beaglebone black, although it's super slow, it actually works. I'd be happy to test arm builds for xmr-stak-cpu.

[fireice-uk]

Watch this issue over the next month or so then =). I'm fairly busy right now, but this is on my todo list. Do you happen to know if beaglebone supports hardware AES (it is an optional feature on ARMv8)?

[weboide]

I don't believe any of the ARMv7 support AES.
Here's a cat /proc/cpuinfo of my beaglebone black and my raspberry pi2 (they both have an arm v7)

Ah... My primary target will be ARMv8 with AES support, but I will try to get something to work on soft-aes too - doubt the hashrate will cover the electricity used though (even in the under 10W range).

[weboide]

That's understandable, even running monerod takes a whole week on a beaglebone :)
I've got a raspberry pi 3 laying around too, so I could test the ARMv8 AES version.

[fireice-uk]

I think Pi3 doesn't have the AES enabled (remember it's optional), but please correct me if I'm wrong.

[nilsmeyer]

It doesn't build on ARMv8 either (after removing the -msse2 and -maes flags):
/usr/src/xmr-stak-cpu/crypto/soft_aes.c:29:23: fatal error: x86intrin.h: No such file or directory #include <x86intrin.h>

[psychocrypt]

Currentl only x86 architectures are supported

[foice]

Anything to go beyond this x86intrin.h ? I got stuck there as well ...

[kreidler1234]

Is there coming another version for a83t arm a7 octa core? stuck at msse2 and maes fault.
Ubuntu on banana pi m3.
Thanks for the answer.

[semeion]

Maybe it can help: https://kazakov.life/2017/11/01/cryptocurrency-mining-on-ios-devices/

[psychocrypt]

Sry we are supporting currently only x86_64, nvidia and amd gpus.

gpu (mali) and armv7 dual mining (tested n working)

Also looking for miner that can run on arm. just clicked @cjwsam links. TY for the odroid forum, this is actualy what i'm trying to play with.
Would be glad to help testing stuff and reporting back if you ever plan on doing so.
Thanks for sharing your time and knowledge.
