[wireguard-dkms] Wireguard dkms module not building

[ambrice]

I did a fresh install onto a Raspberry Pi 4. I installed wireguard-dkms, which installed with no errors, but does not seem to build the module. It returned quickly on install, and find -name wireguard* /lib/modules returns nothing. I tried dkms autoinstall which returns immediately without building anything. I see the module source in /usr/src/wireguard-0.0.20190905, how does dkms find it?

Do you have the headers installed? FYI, you can build from this PKGBUILD just fine:

Yeah, that was it, the headers weren't installed. I would think that they would be listed as a dependency of dkms, or that if you ran dkms without the headers it would give you a relevant error message. But it's working now.
