Closed edisonchan closed 3 years ago

edisonchan commented 3 years ago

https://nvpro-samples.github.io/vk_raytracing_tutorial_KHR/ said there is a SDK 1.2.161 can be download from https://vulkan.lunarg.com/sdk/home , but latest version over there is 1.2.154.

A newer version of the SDK will be soon available. Meanwhile, it is possible to get the headers from https://github.com/KhronosGroup/Vulkan-Headers.

I had try to copy the "Include\vulkan" and "share\vulkan\registry" from https://github.com/KhronosGroup/Vulkan-Headers and the "vulkan-1.lib" from https://github.com/GPSnoopy/RayTracingInVulkan to replace the installed Vulkan SDK 1.2.154 files from https://vulkan.lunarg.com/sdk/home#windows, but still can not build the project from https://github.com/GPSnoopy/RayTracingInVulkan.

how can I fixed this problem?

the error output like these:

The installer for Vulkan SDK version 1.2.162.0 has been publicly released, try that, it should work more smoothly than manual installation. If it's still not working, check your VULKAN_SDK environment variable and see that it points to the correct directory. I'm on Linux so I don't know the exact directory but it should have "1.2.162" in its name.
