Having trouble compiling Telemetry 0.4.0 under Elixir Alpine

Can you run with the environment variable DEBUG=1 or copy out the rebar3.crashdump file from the container so the error can be seen?

Here’s what I got when I ran it again:

$ DEBUG=1 mix deps.compile

** (Mix) Could not compile dependency :telemetry, "/root/.mix/rebar3 bare compile --paths "/builds/rarex/core/_build/dev/lib/*/ebin"" command failed. You can recompile this dependency with "mix deps.compile telemetry", update it with "mix deps.update telemetry" or clean it with "mix deps.clean telemetry"

Have you tried with the cache deleted? I think this can also happen if some of what you have cached is not readable..

I haven’t tried that yet although the app I’m doing this on is pretty fresh, so I’m not sure if this is the cause. So does this mean that I don’t need to install any libraries using apk before doing the compilation?

Seeing this path in a dockerized build makes me think…

It looks like a path from your host OS, not like one I’d expect to see in the guest.

Can you please verify that you have deps and _build in your .dockerignore?

No, that is actually my path :). It is using an old prebuilt rebar3 escript that was built on my machine.

That might actually be an issue, mix local.rebar installs versions it is known to work with, you should not use a different rebar when compiling mix projects.

They aren’t, it is using the version installed my mix local.rebar.

Can you share access to the code? Or at least recreate the issue in a clean/fresh phoenix application which we could clone and experiment with?

This is unrelated to apk, I’m simply suggesting rerunning without _build and deps cached (and deleted locally in case you are including them in the context, better to put them in .dockerignore).
