Как вызвать vkCreateMacOSSurfaceMVK из библиотеки Vulkan? ⇐ C++

[Anonymous]

I try to create a small app based on Vulkan v1.3.275.0 (and MoltenVK driver for macOS).

I successfully bundle my app into *.app with recommended Vulkan structure for macOS. My app opens a window using metal-cpp library and creates a Vulkan instance using MoltenVK driver.

However, now I need to create a surface for Vulkan device and here I hit troubles.

As I got to create a surface on macOS, I need to call vkCreateMacOSSurfaceMVK() (ref) from #include but when I try to include this header my app crashes with errors:

[build] /Projects/my/third-party/vulkan/include/vulkan/vulkan_macos.h:26:9: error: unknown type name 'VkFlags' [build] typedef VkFlags VkMacOSSurfaceCreateFlagsMVK; [build] ^ [build] /Projects/my/third-party/vulkan/include/vulkan/vulkan_macos.h:28:5: error: unknown type name 'VkStructureType' [build] VkStructureType sType; [build] ^ [build] /Projects/my/third-party/vulkan/include/vulkan/vulkan_macos.h:34:19: error: unknown type name 'VKAPI_PTR' [build] typedef VkResult (VKAPI_PTR *PFN_vkCreateMacOSSurfaceMVK)(VkInstance instance, const VkMacOSSurfaceCreateInfoMVK* pCreateInfo, const VkAllocationCallbacks* pAllocator, VkSurfaceKHR* pSurface); [build] ^ [build] /Projects/my/third-party/vulkan/include/vulkan/vulkan_macos.h:34:59: error: unknown type name 'VkInstance' [build] typedef VkResult (VKAPI_PTR *PFN_vkCreateMacOSSurfaceMVK)(VkInstance instance, const VkMacOSSurfaceCreateInfoMVK* pCreateInfo, const VkAllocationCallbacks* pAllocator, VkSurfaceKHR* pSurface); And if to open this header there are really no declarations or other includes for these types:

#ifndef VULKAN_MACOS_H_ #define VULKAN_MACOS_H_ 1 /* ** Copyright 2015-2024 The Khronos Group Inc. ** ** SPDX-License-Identifier: Apache-2.0 */ /* ** This header is generated from the Khronos Vulkan XML API Registry. ** */ #ifdef __cplusplus extern "C" { #endif // VK_MVK_macos_surface is a preprocessor guard. Do not pass it to API calls. #define VK_MVK_macos_surface 1 #define VK_MVK_MACOS_SURFACE_SPEC_VERSION 3 #define VK_MVK_MACOS_SURFACE_EXTENSION_NAME "VK_MVK_macos_surface" typedef VkFlags VkMacOSSurfaceCreateFlagsMVK; typedef struct VkMacOSSurfaceCreateInfoMVK { VkStructureType sType; const void* pNext; VkMacOSSurfaceCreateFlagsMVK flags; const void* pView; } VkMacOSSurfaceCreateInfoMVK; typedef VkResult (VKAPI_PTR *PFN_vkCreateMacOSSurfaceMVK)(VkInstance instance, const VkMacOSSurfaceCreateInfoMVK* pCreateInfo, const VkAllocationCallbacks* pAllocator, VkSurfaceKHR* pSurface); #ifndef VK_NO_PROTOTYPES VKAPI_ATTR VkResult VKAPI_CALL vkCreateMacOSSurfaceMVK( VkInstance instance, const VkMacOSSurfaceCreateInfoMVK* pCreateInfo, const VkAllocationCallbacks* pAllocator, VkSurfaceKHR* pSurface); #endif #ifdef __cplusplus } #endif #endif I found yet one header but it didn't help too.

What's a right way to create a Metal surface for Vulkan on macOS?

P.S. I know there are GLFW and similar libraries but I just want to dig into clean Cocoa and Vulkan (MoltenVK) to understand how to connect them manually.

P.P.S. I am not sure if it's right to call AppKit, MetalKit and other frameworks a part of Cocoa, fix me if I am wrong.
