Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

@jakirkham I wanted to manually test the OSX arm64 build from this PR locally on a M2 Mac machine. I tried to follow the Downloading prebuilt packages from CI section of the Docs. I found it quite confusing and lacking enough details so perhaps I am doing something wrong. In the last commit, I've added the following to conda-forge.yml to enable artifact upload on Azure pipelines

azure:
   store_build_artifacts: true

But I still don't see any uploaded artifacts. Would you mind taking a look?

[danielhollas]

@conda-forge-admin please rerender

[jakirkham]

There are some screenshots with explanations in this issue ( https://github.com/conda-forge/conda-forge.github.io/issues/1424 ), which can help in downloading and testing these

[jakirkham]

Should add if you have recommendations on how to make the docs clearer we would welcome them 🙂

(even more so if in PR form 😉)

[danielhollas]

Haha, yes I was thinking of submitting a PR as I found the instructions very confusing. :-) I actually found the issue and the screenshots definitely helped. Do you think they should be in some form be included in the docs?

Ultimately the step I was missing is the rerender, which I think is not explicitly mentioned.

[jakirkham]

Yeah that was certainly one idea we had for the docs. If you find them helpful, agree we should add them 🙂

Calling out re-rendering in the docs is also a good idea 👍

[danielhollas]

Another question I had about this, is the artifact upload available only on Azure pipelines? I haven't seen the option for the other CI providers.

[jakirkham]

Yeah think it is just GitHub Actions and Azure

It's probably possible to implement on other CI providers, but am not aware of current work on that

[danielhollas]

Now that I've been able to download the artifact I could install the package locally on Mac M2. Unfortunately I am getting this error:

$ erl --version
dyld[36883]: Library not loaded: @rpath/libtinfo.6.dylib

  Referenced from: <64D3CFF0-45A6-37FA-AE4C-05C25E3CF527> miniconda3/envs/erlang-osx/lib/erlang/erts-15.0/bin/beam.smp

  Reason: tried: '/Users/veronikajuraskova/miniconda3/envs/erlang-osx/lib/erlang/erts-15.0/bin/../../../libtinfo.6.dylib' (no such file),
'/Users/veronikajuraskova/miniconda3/envs/erlang-osx/lib/erlang/erts-15.0/bin/../../../libtinfo.6.dylib' (no such file), '/usr/local/lib/libtinfo.6.dylib' (no such file), 
'/usr/lib/libtinfo.6.dylib' (no such file, not in dyld cache)

Googling around a bit it seems that libtinfo should come from ncurses library. Suspiciously, listing installed packages with mamba list only shows erlang and not other dependencies. So I suspect that runtime dependencies are somehow not correctly specified for the package. I'll need to have a closer look.

[danielhollas]

Okay, it seems that conda doesn't install package dependencies when installing from *.conda package file?? Installing ncurses and zlib manually solved the issue and we verified that erl --version works.

Unfortunately, the artifact doesn't contain the compiled test suite so we haven't run it. I don't know how much work it would be to try to upload the test suite as artifact as well, and if it is worth the hassle.

Apart from that I think this is ready to go. :rocket:

[jakirkham]

That's right. Would use file://<path to build_artifacts as the channel to install erlang

This should pull in dependencies
