Doesn't work on a Rock64

[ab1jx]

I'm not sure if it's because it's ARM v8 or if it's because it's 64 bits, but using the neon option to make it do the assembly gives this config.log. Without that it just compiles the C and works, but at 0.95 k hash/sec or so. Does 1.3 on my RPI 3B.

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by cpuminer configure 2.5.0, which was
generated by GNU Autoconf 2.69. Invocation command line was

$ ./configure CFLAGS=-O3 -mfpu=neon

cpuminer currently has no specialized code for AArch64.

The error you're getting is explained here.

OK, thanks.
