@LongMeters How did you clone the Darling project? Did you recursively clone the submodules?

[LongMeters]

i used this command git clone --recursive https://github.com/darlinghq/darling.git

Looks like PDFKit lives in src/frameworks/PDFKit. Does this folder exist on your machine? Are there any files in the folder?

What does git status return?

I was also getting these errors via Fedora through WSL2 on Windows 11.

Solved it by installing llvm-devel, glslang, and python2 from DNF, and then installed VulkanSDK from https://vulkan.lunarg.com/sdk/home#linux where I used the SDK Installer download, extracted to the directory I wanted it to stay on my system, and used the setup-env.sh to set the environment variables to find the Vulkan libraries.

EDIT: Just noticed you were getting some other error after those, unsure if this resolves your The dependency target "PDFKit" of target "Quartz" does not exist. error.
