@Arevjensen Gitlab CI runs in a docker container, in this case, rust:latest as specified at the top of the file here. As you've discovered the rust container doesn't include lld or clang by default.

When doing it this way, you're installing these each and every time. I've gone ahead and bundled all the dependencies as of Chapter 1 into a single docker image.

If you'd like you can replace image: "rust-latest" with image: "aestusvitae/rust-ci:latest" and remove the installs (apt, cargo install, rustup component add) from your CI scripts, and CI runs should be noticeably quicker.

You can even build the image yourself if you're so inclined. (or if I fail to keep mine up to date) The Dockerfile is very simple.
