@uilianries @SSE4 please approve

it's probably not needed on all platforms

libsystemd is available only on Linux, so with this change grpc can't be built on Windows/Macos

[AndreyMlashkin]

valid point. Thanks for saving CI time :)

Running into this myself today, thanks for the PR. However, the "libsystemd/255" conan package appears to require conan v1.60. Not sure if it is appropriate to add that as an explicit check in this project so it is more clear to consumers?

The root cause is that libsystemd/255 fails to import "move_folder_contents", a 1.60.0 feature.

ERROR: libsystemd/255: Cannot load recipe.

Thanks for mentioning this, @bhutch29. I added a PR to fix this in the original recipe #22447.

[bhutch29]

Is there documentation anywhere for pulling down this repository and doing something like "export-pkg" locally so I can test out this PR? I have cloned the repo but I am getting weird errors when attempting to install/build/export-pkg the grpc recipe, I am hoping that there is just a step I am missing.

I am not 100% sure, but it seems like these are recipes but they don't have the original sources? So that's why I can't build/export them locally?

[valgur]

@bhutch29 Doing conan create . --version <version> in the directory with the conanfile.py builds the recipe and stores it in the Conan cache under ~/.conan2/p/b. After that, the version in the cache will get used instead a version from ConanCenter for that package+version combination.
