I am on centos 6, and my kernel version is 4.9.34.I just compiled and
installed *gcc version 8.1.0 (GCC) *to build wireguard but my kernel was
originally built with gcc-4.4.7. Will that be a problem ?
Is there a way to exclude Elliptic Curve 25519 or any of the Elliptic Curve
while making ? Any other suggestions please ?


Thanks
