Hi,


Up-to-date CentOS Linux release 7.4.1708

$ uname -r

3.10.0-693.2.2.el7.x86_64


Followed the official instructions at https://www.wireguard.com/install/ to install the latest wireguard snapshot on a fully up-to-date CentOS 7.4 but the kernel module compilation failed:

$ cat /var/lib/dkms/wireguard/0.0.20171001/build/make.log
