I’m in the process of setting up a node on the floonet but every time I run “grin --floonet” I end up with “Illegal instruction (core dumped)”.

I also had this when I installed the green from the file at this link
but when I installed the green for this instruction: https://github.com/mimblewimble/grin/blob/master/doc/build.md ,all it worked.

Same as @ackur. I had the same issue trying to run grin from the release, but building grin from source worked.

Just be sure to delete you .grin directory first.

Looks like their builds are targeting versions of CPUs that support the AVX instruction set. Therefore the code contains AVX instructions - on a CPU that doesn’t support the AVX instruction set these instructions are “illegal”. See issue https://github.com/mimblewimble/grin/issues/2519
