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.

I do have some suggestions for making it better though...

For recipe:

• It looks like the 'jpeg' output doesn't have any tests.

[isuruf]

libjpeg.8.dylib from this package has (compatibility version 8.0.0, current version 8.2.2) while the one from jpeg package has (compatibility version 13.0.0, current version 13.0.0). This has to be fixed before merging this.

@isuruf ok

Changing the soversion like this fixes the current-version and comaptibility-version, but breaks the install name.

[jakirkham]

How would you recommend we proceed then?

Thanks @jschueller for tackling this! Since this seems to be a tricky, could one of the conda-build/conda-forge wizards helps with some tricks?

This is one blocker for packaging imagecodecs: conda-forge/staged-recipes#10331.

Could we mark all the old builds as broken? does anything actually use jpeg-turbo as of today?

@conda-forge-admin please rerender

@isuruf I fixed the compatibility/current version property, I believe this is ready for review
