See SwiftPackageIndex/PackageList#7552 for context.

Which package(s) are showing incorrect data?

mrLSD/llvm-api-swift

Please explain what data is incorrect and what you expected to see

Builds are failing because of a missing operating system level dependency on the LLVM SDK.

Other information

I'm tracking this here, as while a custom base image for Linux will likely solve the issue for that platform, we have not yet implemented this for Apple platforms.

@mrLSD you mentioned it needed a brew install llvm and an ENV variable set. Could you list in a reply to this the exact steps/commands needed to get this compilation working on macOS so we can bear in mind this requirement as we design our support for custom operating system dependencies in Apple platform builds.

I can't promise this will be implemented quickly, but knowing the explicit requirements (and tracking packages that would benefit from the feature) will help us prioritise it.

Thanks!

Thank @daveverwer
There's my example CI how to manage LLVM environment for MacOS.
Alternatively just add pkg-config file, and build will pass for.

Please which way is appropriate, and I can prepare CI Linux matrix in my repo for that.
