Hi! This is the staged-recipes linter and your PR looks excellent! 🚀

[conda-forge-admin]

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 (recipes/kmsxx/meta.yaml) and found some lint.

Here's what I've got...

For recipes/kmsxx/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.

@traversaro before I ping help-c-cpp do you have any suggestion on this? The error is a missing linux header AFAIU:

By the way, this is a missing piece towards building picamera2.

Sure! Sorry I am currently a bit far from keyboard so I may be slow to reply. Based on https://conda-metadata-app.streamlit.app/Search_by_file_path, I guess that is a Linux kernel header, so you can add a dependency on the kernel_headers or sysroot CDT, I do not remember exactly.

[carlodri]

Thanks! I was expecting something like that but didn't know where to look. That web tool is fantastic, didn't know about it.

Still, that header cannot be found. I'm thinking that it might be a problem with the include path..

[traversaro]

Probably the correct dependency is the sysroot one that also sets the include path?

[conda-forge-admin]

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 (recipes/kmsxx/meta.yaml) and found some lint.

Here's what I've got...

For recipes/kmsxx/meta.yaml:

• ❌ You're setting a requirement on sysroot_linux- directly; this should now be done by adding a build dependence on {{ stdlib("c") }}, and overriding c_stdlib_version in recipe/conda_build_config.yaml for the respective platform as necessary. For further details, please see META: {{ stdlib("c") }} migration conda-forge.github.io#2102.

Well, we moved forward 🥳 (thanks @traversaro!), and now I'm stuck here:

  ERROR (kmsxx,bin/fbtest): $RPATH/libkms++util.so.0 not found in packages, sysroot(s) nor the missing_dso_whitelist.
.. is this binary repackaging?

That sounds like a shared library not being installed? If fbtest is not actually useful, perhaps we can just delete it from the install.

[carlodri]

@traversaro I would be grateful if you could review the recipe as well as @conda-forge/help-c-cpp

Thank you!

Hi! This is the staged-recipes linter and your PR looks excellent but I have some suggestions.

File-specific lints and/or hints:

• recipes/kmsxx/meta.yaml:
  • hints:
    • It looks like you are submitting a multi-output recipe. In these cases, the correct name for the feedstock is ambiguous, and our infrastructure defaults to the top-level package.name field. Please add a feedstock-name entry in the extra section.
