Building on M1 Mac error

On a mac with m1 apple silicone. Trying to make mcl:

What commands did you type? Could you try make clean?

On my M1 mac,

make test -j4

goes well.

clang -v
Apple clang version 12.0.5 (clang-1205.0.22.9)
Target: arm64-apple-darwin20.6.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

That works. I was trying make -j4 which was failing.

I was trying make -j4 which was failing.

Thank you for the information. I've fixed it. https://github.com/herumi/mcl/commit/36a3013cae4df452601bbeb5f78afc5c8748f715

Awesome, thanks @herumi !
