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

I wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found some lint.

Here's what I've got...

For recipe/meta.yaml:

• ❌ This recipe is using a compiler, which now requires adding a build dependence on {{ stdlib("c") }} as well. Note that this rule applies to each output of the recipe using a compiler. For further details, please see META: {{ stdlib("c") }} migration conda-forge.github.io#2102.

For recipe/meta.yaml:

• ℹ️ The recipe is not parsable by parser conda-recipe-manager. The recipe can only be automatically migrated to the new v1 format if it is parseable by conda-recipe-manager.

@minrk I got two PRs with the same title, #109 and next this one #110. I merged the first (everything looked good) without noticing the second. I'm not sure what's the purpose of this one.

The previous one was for main ( #109 ) and this one is for 3.x

Looks like migrations are enabled for both

mpich-feedstock/conda-forge.yml

Lines 1 to 3 in bbc7c84

	bot:
	abi_migration_branches:
	- 3.x

Note: main is always included in the list

[dalcinl]

and this one is for 3.x

Oh, I totally forgot 🤦‍♂️. Then this PR may require some added love.

No worries. It's good to check. Sometime the bot does accidentally send multiple PRs to the same branch, which is good to catch and fix
