pyvulkan gives VkErrorExtensionNotPresent error, but extension is present.
Hi,
I've noticed that there are several situations where I get a VkErrorExtensionNotPresent
from pyvulkan, yet I believe the extension is actually present in my Vulkan SDK. I had a look at the api.xml and I think there might be a bug in the parser. In any case, here is any example of the bug. Wondering if you could comment if this is indeed a bug in this repo or I'm misreading it. Thank very much!
import vulkan as vk
ext = [vk.VK_KHR_GET_PHYSICAL_DEVICE_PROPERTIES_2_EXTENSION_NAME,
vk.VK_KHR_TIMELINE_SEMAPHORE_EXTENSION_NAME]
info = vk.VkInstanceCreateInfo(
pNext=None,
flags=0,
pApplicationInfo=None,
enabledLayerCount=0,
ppEnabledLayerNames=[],
enabledExtensionCount=len(ext),
ppEnabledExtensionNames=ext)
instance = vk.vkCreateInstance(info, None)
I get:
Traceback (most recent call last):
File "/home/henry/ai/glass-imaging/image-generator/image_gen/tests/instance_extension.py", line 14, in <module>
instance = vk.vkCreateInstance(info, None)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Yet, I see:
