I am using Rust 1.79.0

When building my previously working application (https://github.com/ZuInnoTe/rust-ebpf-localnet-kernel-filter-study) with latest version of Rust and latest version of aya, I get the following error:

There seems to be an issue when building the dependency and not the application itself. Any idea what can cause this?

tamird commented

Seems like an easy fix; change :: to :. Care to send a PR?

tamird commented

But also the original commit references this doc which suggests two colons is the canonical form with rust 1.78 or higher...?

tamird commented

Also: how are you using rust 1.79? Aya ebpf requires nightly if I remember correctly. Have you ever built your application successfully before? What changed since you last did?

jornfranke commented

Will check if it picks up the nightly, but I wonder why not. Nothing changed, it was built before successfully.

tamird commented

What is the version of your nightly?

jornfranke commented

Ahh you brought me on the right track, I forgot a

rustup update nightly

Thanks!
