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.

This seems pertinent, RE: Travis CI jobs aren't being generated here (they should be): Gitter Thread

In case the link is a hassle, here's the content:

FYI if your feedstock uses Travis CI and you are not seeing Travis CI builds, please make sure the commit author (yourself or another contributor) does a relogin to Travis CI and then restart CI. This should remedy the issue

Please reach out in the thread if you have questions or issues. Thank you! 🙏

I will look into it later today. I think there may be issues beyond just compiling natively, but we shall see...

        raise exc
    conda_libmamba_solver.conda_build_exceptions.ExplainedDependencyNeedsBuildingError: Unsatisfiable dependencies for platform linux-aarch64: {MatchSpec("openblas-ilp64")}
    Encountered problems while solving:
      - nothing provides requested openblas-ilp64
    
    Could not solve for environment specs

[ngam]

Seems like we have two distinct issues now:

1. Tests failing and testing taking more resources --- we could likely fix this by adjusting our tests on all platforms
2. Missing openblas-ilp64 on aarch64 --- I believe we discussed this before and I don't remember what happened

I can probably push this forward, but my general use of Julia is close to zero these days and I am likely out of the loop on what's happened in julialand.

Hi @mfansler, what exactly is your need (aarch or ppc)? Are you interested in helping to get these issues resolved?

[mfansler]

@schlichtanders would be the one to ask - he has the interest in Arch builds. I was mostly just querying about the status of the PR to communicate this to others.

[schlichtanders]

I am running stuff on Arm64 with CondaPkg and wanted to use r-juliacall. That depends on julia and because of this it is not installable on Arm64 out of the box. I now created a workaround for myself - a custom build of r-juliacall. But in general, it would be great if julia-dependent conda packages would just install everywhere out of the box.

[mkitti]

We have a few choices here:

1. Work on Julia dependencies in the conda-forge ecosystem to better accomodate Julia's needs
2. Compromise conda-forge principles and download binaries built elsewhere (e.g. juliaup)
3. Create a distinct julia conda channel that just download binaries built elsewhere
4. Don't use conda to obtain julia

[schlichtanders]

For me all options are fine (my motivation is very practical - being able to install the conda package r-juliacall out of the box.)
