wgpu example on Mac results in `unsupported features were requested: SPIRV_SHADER_PASSTHROUGH`

[Cactice]

Expected Behaviour

Successfully run the wgpu example on Mac with no error.

Example & Steps To Reproduce

0. git clone --recurse-submodules https://github.com/EmbarkStudios/rust-gpu
1. cd examples/runners/wgpu
2. cargo run
3. Get error unsupported features were requested: SPIRV_SHADER_PASSTHROUGH

I used above method because cargo run --bin example-runner-wgpuhad an issue

cargo run --bin example-runner-wgpu
error: no bin target named `example-runner-wgpu`

Did you mean `example-runner-cpu`?

I tested on master and the patch branch on this PR #852 but the issue occurred on both branches.

[andrusha]

You need to install MoltenVK and use this patch which enabled vulkan-compatibility in wgpu #852

[andrusha]

I also made a minimal compute shader example you can check https://github.com/andrusha/rust-gpu-wgpu-compute-minimal

[Cactice]

Thank you andrusha.
I assumed wgpu would have moltenVK linked but it seems not.
I was able to get the sky to show up after installing Vulkan SDK.
Although there were lots of validation errors.
