Is it required to call gladLoaderLoadVulkan one more time with VK_EXT_debug_utils?

[yehuohan]

When VK_EXT_debug_utils is enabled and we want to call vkCreateDebugUtilsMessengerEXT before physical device is created, it is seemed required one more call gladLoaderLoadVulkan(instance, NULL, NULL). (Getting address of vkCreateDebugUtilsMessengerEXT only need a valid instance)

So with the builtin loader it would be like this:

gladLoaderLoadVulkan(NULL, NULL, NULL);
gladLoaderLoadVulkan(instance, NULL, NULL);
gladLoaderLoadVulkan(instance, phyiscal_device, NULL);
gladLoaderLoadVulkan(instance, phyiscal_device, device);

Is it right?

This sounds correct. The first call resolves all global functions like vkCreateInstance, the second one all instance functions (including the one youre interested in) the 3rd one to populate all device extensions, the fourth one to reload all device functions (optional see here).

Are you having any issues with this? Maybe the triangle example can help you as a rough reference (does only reload 3 times not 4).

I think the issue I caught had beed addressed. And very thank to the example that helped me a lot.
