Hi,
I encountered the following build error on Mellanox BlueField ARMv8 CPU
(Cortex-A72).
It is CentOS 7.4
$ cat /etc/redhat-release
CentOS Linux release 7.4.1708 (AltArch)
And gcc is 4.8.5
$ gcc --version
gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-28)
FYI,
$ uname -a
Linux dragon61-bf 4.11.0-22.el7a.aarch64 #1 SMP Sun Sep 3 13:39:10 CDT 2017
aarch64 aarch64 aarch64 GNU/Linux
Is it a known issue or am I missing something?
