RHEL8 package install or build fail

folks, current wireguard seems not to install or build on RHEL 8.0

(1) via yum and the wireguard repo at
https://copr-be.cloud.fedoraproject.org/results/jdoss/wireguard/epel-7-$basearch/

[root@<>]# yum install wireguard-dkms wireguard-tools
...
Copr repo for wireguard owned by jdoss
          1.7 kB/s | 3.5 kB     00:01
Error:
 Problem 1: conflicting requests
  - nothing provides dkms needed by
wireguard-dkms-1:0.0.20190601-1.el7.noarch
 Problem 2: package wireguard-tools-1:0.0.20190601-1.el7.x86_64 requires
wireguard-dkms, but none of the providers can be installed

and (2) building without much trying albeit -

[root@<> src]# make
  CC [M]  /root/WireGuard/src/main.o
In file included from <command-line>:
/root/WireGuard/src/compat/compat.h:828:20: error: redefinition of

Thanks in advance for hints,

Hi Mike,

While RHEL8 is out, it looks like CentOS 8 is not yet, so I don't have
much of a way to make sure our compat layer works well for RHEL8. Do
you have any suggestions on how I could obtain access to a running
RHEL8 box and its kernel sources?

Jason

Hi Jason,

You can get free developer access to RHEL.

Thanks for the heads up. I should have this settled shortly then.

Hello Jason,
applying the patch for compat.h resolves - compiling works fine. However
the Netlink headers libmnl.h were missing, seems there is no standard
RHEL8-dev package for the library, had to take it from netfilter.org/Fedora.
Then OK:

[ 9386.069776] wireguard: WireGuard 0.0.20190601-7-g44070b9-dirty loaded.
See www.wireguard.com for information.

[root@paris src]# wg show
interface: wg0

Apparently you have to add the "codeready" repository in RHEL8, as
libmnl-devel was removed from the main repo according to the release
notes.

It looks like you can enable other repos for Copr builds but it isn't 
working when I enable:

https://cdn.redhat.com/content/dist/rhel8/$releasever/x86_64/codeready-builder/os

I will see if I can get the maintainers of Copr to enable this repo by 
default for RHEL8 buildroots.
