Is the error reported because arm is not supported? Because I've seen similar speeches.#1804

[skoren]

Yes, this is an issue with ARM compilation, from a third-party library canu uses. It looks like that library does have ARM support so it could be updated but you'd likely encounter other errors because we've never compiled on an ARM processor and don't have access to one to test.

I'm going to close this issue since it's redundant with the other ARM support request. If we do get access to a test machine, that issue would get updated.
