Build error

[kernelb00t]

Hey !
Trying to build Caddy with the tailscale module on RPi 4 (RPi OS Bullseye, up-to-date), with xcaddy downloaded from apt. Caddy worked previously by installing it with apt.

I just exec xcaddy build master --with github.com/tailscale/caddy-tailscale, but it fails also when compiling vanilla (xcaddy build and it's the same error)

Here are the logs :

Make sure you're using the latest Go version.

[kernelb00t]

I think I am, apt update says all packages are up-to-date, and I have golang installed with apt.

[francislavoie]

Distros usually ship old versions of Go. Make sure you have at least Go 1.20. You may need to install it manually (essentially just download and unzip it).

[mholt]

Yep, surely an old go version. Maybe we should have xcaddy print it.

[kernelb00t]

I have go 1.15, you were right. I'll try when I have the time (tomorrow I think).

[kernelb00t]

Haha, it broke again 😂

Same error without module caddy-tailscale.

[francislavoie]

You're not supposed to run xcaddy with no arguments unless you're trying to build a development build of a plugin you're working on which is in your PWD. You need to use xcaddy build --with ...

[kernelb00t]

Yes, I realised this too late. It's actually all right, it built without errors without the caddy-tailscale module, but with it it throws an error, so I'll just post an issue there and not forget to read the doc 😅
Thanks !
