Which version of GCC is it specifically? Might be just too old to know about Haswell, in which case I don't think we care about it all that much.

-> root@AAA ~ ? # gcc --version
gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-44)

GCC 4.8.5 is from 2015, I'm fairly certain no one will bother doing anything to support it. You should really upgrade to more modern and supported OS or install newer GCC in some way yourself.

Okey. Thanks for your reply.
I catched some build errors:
The reason may be that some specific version of compilers does not support
-march=haswell
.Could we sure that compiler supports
-march=haswell
when set build flag?
