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

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/libadwaita/recipe.yaml) and found some lint.

Here's what I've got...

For recipes/libadwaita/recipe.yaml:

• ❌ The recipe must have some tests.

The build fails with:

src/stylesheet/meson.build:88:40: ERROR: Dependency 'gio-2.0' tool variable 'glib_compile_resources' contains erroneous value: '$PREFIX/bin/glib-compile-resources'
This is a distributor issue -- please report it to your gio-2.0 provider.

Any idea @conda-forge/help-c-cpp ?

Now failing with ERROR: Program 'update-mime-database' not found or not executable 🤔

This is amazing that you are helping to package this @davidbrochart, thanks so much!

For the update-mime-database error, I think you need shared-mime-info as a build requirement.

Any reason not to go straight to latest 1.8.2 version?

I also maintain a patch for Windows to build libadwaita without AppStream support since AppStream uses features that aren't compatible with MSVC. It could always be a follow-up PR, but it would be amazing if this recipe supported Linux, macOS, and Windows.

Are you sure? shared-mime-info doesn't seem to be a conda-forge package.

Hey @davidbrochart, I noticed in the build log:

 │ │ gtk| Program sassc found: NO
 │ │ subprojects/gtk/gtk/meson.build:737:10: ERROR: Program 'sassc' not found or not executable

libadwaita does depend on this for style sheets, I think you need libsass as a build requirement. I can also try to build this locally and help troubleshoot.

[davidbrochart]

Thanks @danyeaw, I tried but https://github.com/conda-forge/libsass-feedstock is actually a Python binding of the libsass C/C++ library.
I think we will have to have different outputs in that feedstock.

Hi @davidbrochart, I just remembered that I also had a PR #30909 that was also trying to add libadwaita. I looked more at this and you are absolutely right about libsass being Python bindings. It looks like we'll need sassc and also libsass-lib (or libsass-native) whatever we want to call the actual libsass.
