Support for MoltenVK (MacOs)? about vulkan HOT 8 CLOSED

Hello @aarbour,
Thanks for opening this issue.
Sadly, I can't test on IOS but I can upgrade this wrapper to the last Vulkan version.

I let you know when it's done, and then you will be able to test again.

I have updated the wrapper to the 1.1.71 version, can you try again please ?

Ok I understand the problem, I don't load the MoltenVK shared library.
Can you give me the name of the MoltenVk Shared library ?

from vulkan.

So under the mac SDK download it is under the MoltenVK folder for both IOS and macOS. I am trying to use the macOS libs which has a:

• libMoltenVK.dylib
• MoltenVK.framework
• MoltenVK_icd.json

These are specific to macOs purely because of Apple's lockdown of Metal. Let me know if you need more information.

We are going to update the code as is to check if it works.
Can you try the following test on your computer and let me know if it's working:

• Localize loaded version of vulkan (in your terminal):

python -c "import vulkan; print(vulkan)"

You should see the path to the __init__ file.

• Open the file _vulkan.py next to the __init__ file.
• Line ~97:
  Replace

_lib_names = ('libvulkan.so.1', 'vulkan-1.dll')

by

_lib_names = ('libvulkan.so.1', 'vulkan-1.dll', 'libMoltenVK.dylib')

It should work, and you can test it.
Let me know !

Worked just fine. I followed the getting_started from the vulkan docs and put the libs in the appropriate folders. I am sure adding them to the path would render the same result.

One note that I'll need to figure out is that running one of the examples, I get:

raise Exception("validation layers requested, but not available!")
Exception: validation layers requested, but not available!

I'll need to do some research but for now, the package loags.

Ok, I'm adding it to the source code. Thanks!
