The error is with clang

Apple LLVM version 10.0.0 (clang-1000.10.44.4)
Target: x86_64-apple-darwin18.2.0

It's caused by the option mno-fused-add in Makefile.config:

# Architecture specific flags
AFLAGS = -D_GNU_SOURCE -pthread -fno-tree-vectorize -m64 -march=native -mno-fused-madd

Hi Jorge,

I have replaced the -mno-fused-add flag with the ffp-contract flag which should work for clang, let me know if it works on your system.

Cheers, Gagandeep Singh
