vkCreateDebugReportCallback EXT not linking, but every other functions in vulkan.h works perfectly

Question

While trying to get Vulkan validation layers to work, I got error LNK2019:

1>Renderer.obj : error LNK2019: unresolved external symbol vkCreateDebugReportCallbackEXT referenced in function "private: void __cdecl Renderer::_InitDebug(void)" (?_InitDebug@Renderer@@AEAAXXZ)

Now the odd thing is that every other function in vulkan.h works perfectly.

I have vulkan-1.lib linked, and I run the AMD implementation of Vulkan. The library is from the Vulkan SDK.

The debugging functions from debug_report_ext are not part of the Vulkan core. You need to dynamically load them from the instance via vkGetInstanceProcAddr after making sure that it's actually supported:

PFN_vkCreateDebugReportCallbackEXT CreateDebugReportCallback = VK_NULL_HANDLE;
CreateDebugReportCallback = (PFN_vkCreateDebugReportCallbackEXT)vkGetInstanceProcAddr(instance, "vkCreateDebugReportCallbackEXT");

See my Vulkan debugging helper unit for details.
