Compile error?

[xieydd]

When i compile the demo in macos, some error happend:

/Users/xieyuandong/Workspace/dl-algorithm/VulkanDemos/examples/63_RTXRayTracingMesh/RTXRayTracingMeshDemo.cpp:1284:2: error: unknown type name 'VkPhysicalDeviceDescriptorIndexingFeatures'; did you mean
      'VkPhysicalDeviceDescriptorIndexingFeaturesEXT'?
        VkPhysicalDeviceDescriptorIndexingFeatures                      m_IndexingFeatures;

} VkPhysicalDeviceDescriptorIndexingFeaturesEXT;

Can you have a look at it? @BobLChen

I will take a look at it. Raytracing demo should be disabled on macos.

[xieydd]

Thanks for your reply, if raytracing is not support in macos, i will consider try the demo in ubuntu. 👍

[BobLChen]

Hi, raytracing based on gtx or rtx graphics card. Check your graphics card if you want to try raytracing.😀 Link

[xieydd]

👍 My GPU Device is not support raytracing, sadly ：(

[BobLChen]

This demo based on opengl, it should be support on all platforms.

@BobLChen I want to learn something about vulkan : ( I annotation RTX part, and it works. But when i run , other error happend:

Environment must be setup and reinstall vulkan sdk. vscode config

"environment": [
                {
                    "name": "LD_LIBRARY_PATH",
                    "value": "${workspaceFolder}/external/vulkan/linux/lib"
                },
                {
                    "name": "VK_LAYER_PATH",
                    "value": "${workspaceFolder}/external/vulkan/linux/etc/explicit_layer.d"
                }
            ],

[xieydd]

Sorry, i still in macos, and i set ENV like this:

export LD_LIBRARY_PATH=Users/xieyuandong/Workspace/dl-algorithm/VulkanDemos/external/vulkan/macos/lib:${LD_LIBRARY_PATH}
export VK_LAYER_PATH=Users/xieyuandong/Workspace/dl-algorithm/VulkanDemos/external/vulkan/macos/explicit_layer.d:${VK_LAYER_PATH}

But same error; I must run it in xcode? should i download vulkan sdk?

[BobLChen]

You must run it in xcode.😀

[xieydd]

Tks, i successfly run in macos.
