I have the impression that the only binary vulkan-samples installs is /usr/bin/spirv-cross . Are there other packages that install more samples?

I suppose you need to look at compile and install logs for vulkan-samples. And how the installed items get split into packages. I’m short, inspect ${WORKDIR} for it.

Greetings,

I see the libvulkan.so.* libs now, but I don't see any sample binaries that look like Vulkan. Is there a list somewhere for all the files in vulkan-samples?
Regards

If the samples don't link with libvulkan directly, it won't get pulled
into the images. How are they loading that library, is it via dlopen()
somewhere? Invisible dlopen() dependencies typically need to be listed
explicitly in RDEPENDS.

As a quick fix, you can add vulkan-loader to the same
CORE_IMAGE_EXTRA_INSTALL list.
