Lwjgl3: When using Vulkan LWJGL crashes when loading GLFWVulkan class with NPE

[Texasjake95]

• LWJGL version: 3.2.3
• LWJGL build #: 13
• Platform: MacOS
• Module: Vulkan

When trying to run the HelloVulkan sample it crashes with java.lang.NullPointerException: A required function is missing: _glfw_vulkan_library at the glfwVulkanSupported() call

Hey @Texasjake95, thank you for reporting this.

GLFW's configuration for MoltenVK has been broken since May. The cause was a bad rebase in the LWJGL-CI/glfw repository. It will be fixed in 3.2.4 build 2. I also relaxed it, so that using a GLFW build without _glfw_vulkan_library results in a simple warning instead of an error.

Until then, you may download the latest libglfw.dylib snapshot and use -Dorg.lwjgl.glfw.libname=<path> (or Configuration.GLFW_LIBRARY_NAME.set(<path>) to replace the 3.2.3 build.

Thanks for the quick response! I can confirm that the libglfw snapshot you linked fixed the problem
