Quantum doesn't seem compatible with Elixir 1.12 #487

Closed hickscorp closed 2 years ago

When running Dialyzer over our project, we get the following errors:

lib/quantum.ex:269:unknown_function
Function GenStage.cast/2 does not exist.

@hickscorp that seems not to have anything to do with the elixir version.

Do you have any compile warning?

Did you clear the _build directory, deps directory and the dialyzer cache? Does it still happen then?

hickscorp commented 2 years ago

Yes - _build directory was nuked, as well as deps to get things built from scratch. I don't recall seeing compile warnings.

@hickscorp This does not seem to be a quantum issue. Quantum defines a dependency to gen_stage and therefore expects it to be present.

I'm currently updating the CI to the newest version. As you can see, dialyzer passes with current Elixir / Erlang Versions: https://github.com/quantum-elixir/quantum-core/runs/3815811406?check_suite_focus=true

Therefore I conclude, that this is not a quantum bug and will convert this issue to a discussion instead.
