ci: build universal dylib

vkd3d configuration fails:

checking for -lvulkan... not found
checking for -lvulkan-1... not found
checking for -lMoltenVK... not found
configure: error: libvulkan and libMoltenVK not found.

Perhaps you know what to do about this?

I'm confused... were we not installing the Vulkan SDK as a MacOS prerequisite before?

Thanks for asking the question. It made me dive deeper.
Yes indeed, we're building Vulkan-Loader as a dependency of vkd3d.

The issue was the ;-semicolon was splitting the -DCMAKE_OSX_ARCHITECTURES=x86_64;arm64 in two arguments.
Escaping the string fixes it.

Can you test the macos artifact before merging?

[thatcosmonaut]

You're the best. Will test today.

Just tested on my MBP 2012 and it recognizes the architecture just fine, but it's complaining about an unrecognized symbol because my OSX version is too old (10.15). That's fine, SDL GPU is technically unsupported on my hardware anyway, but we might want to add -DCMAKE_OSX_DEPLOYMENT_TARGET=11.0 so that the binary doesn't target OSX 14 unnecessarily.

That's easy for the CMake projects, but what CFLAGS should be passed to vkd3d?
Does that mean -mmacosx-version-min=11.0?
And when targeting iphoneOS, is the option also -mmacosx-version-min=X.Y?

[madebr]

Looks like every apple platform has its option name:

I'll have to manually pass -mmacosx-version-min=11.0 to CFLAGS.

Just tested again and the artifacts seem to only have arm64.

That's weird. All of them? Or some of them?

[thatcosmonaut]

Oh sorry I meant the MacOS artifact.

[madebr]

Oh sorry I meant the MacOS artifact.

I meant to say, all libraries/executables in the macOS archive?
When I look at the logs, I see the compiler gets -arch x86_64 -arch arm64.
So it'd surprise me if all of them are missing x86_64.

[thatcosmonaut]

False alarm, I was checking an executable from the wrong folder 😅

[thatcosmonaut]

Merged, thanks!
