running solver_avx2: Illegal instruction (core dumped)

[lowagner]

on linux x86_64, i run:

cd Linux/demo
make
./solver_avx2

and get

Reading input.bin
Running solver...
Illegal instruction (core dumped)

for whatever reason, solver_avx1 seems to work.

this seems to also be the case if i run fasm equihash_avx?.asm -m 400000 on the asm parts, and copy in their resulting .o files.

The error message means that your CPU does not support AVX2 instruction set.
This is the reason for writing solver_avx1, to support older CPUs.

ok, thanks!
