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.

@conda-forge-admin, please rerender

Thanks, @manics ❤️ I have limited experience with these arm migrations (and no way to test the changes) but in general huge support for getting this out there for proper testing (assuming of course there are no downsides for existing builds 🙂 )

[manics]

I don't have any way to test either 😄
It should just add another build/deployment combination, and shouldn't affect any existing packages. Merge if you want to give it a go....

[joshmoore]

Let's do it!

Hi, I'm willing to help test locally on my M1 if you can give me some instructions!

[joshmoore]

@psobolewskiPhD, great, thanks!

It looks like the files have been uploaded to https://anaconda.org/conda-forge/zeroc-ice/files

I assume conda install -c conda-forge zeroc-ice=3.6.5 should let you try this out.

[psobolewskiPhD]

OK, so this JustWorks with arm64 miniforge

mamba create -y -n ice-test python=3.9
conda activate ice-test
mamba install omero-py 

But! Something isn't crosscompiled correctly, because:

>>> import omero.clients
