Bill,

Thanks. That got it. Now I can walk through tutorials.

$ ./VulkanTest
4 extensions supported

Okay, I’m clearly missing something about the framework build. I’m seeing the same issues from the command line.

I use this to compile:
c++ -std=c++14 -I/Users/andrewl/MoltenVK/Molten-0.13.0/MoltenVK/include -o VulkanTest main.cpp -framework Cocoa -F/Users/andrewl/moltenvk/Molten-0.13.0/MoltenVK/macOS -framework MoltenVK -framework Metal

This program:

#include <iostream>

#include <vulkan/vulkan.h>

int main() {
    uint32_t extensionCount = 0;
    vkEnumerateInstanceExtensionProperties(nullptr, &extensionCount, nullptr);

    std::cout << extensionCount << " extensions supported" << std::endl;
}

And I get this error:

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_CAMetalLayer", referenced from:
      l_OBJC_$_CATEGORY_CAMetalLayer_$_Molten in MoltenVK(MoltenVK-x86_64-master.o)
      objc-class-ref in MoltenVK(MoltenVK-x86_64-master.o)
ld: symbol(s) not found for architecture x86_64

You are likely accidentally building the iOS versions of the product for the simulator, and the simulator does not support Metal.

You either have to build and deploy on actual hardware, or build and deploy for your desktop mac.
