我試圖用Vulkan繪製HTC Vive的東西。vkCreatePipeline失敗並驗證層段錯誤
我啓用了驗證層並且程序給了我vkCreateGraphicsPipeline內部的段錯誤。段錯誤發生在VkLayer_core_validation.dll。如果這不夠奇怪，則發生段錯誤的功能是vkEmurateInstanceExtensions。所以，我測試了沒有驗證層，然後vkCreateGraphicsPipeline失敗，結果是VK_ERROR_VALIDATION_FAILED_EXT。
我現在已經閱讀了本教程的管道部分，我接下來幾次都沒有發現任何錯誤。另外我嘗試了較老版本的Vulkan SDK，但唯一的區別在於vkCreateGraphicsPipeline內部的vkGetInstanceProcAddr中發生了段錯誤。

編輯1：將調試圖層更改爲驗證圖層。
附加信息： 福爾康SDK版本1.0.54.0
一些更多的細節會有幫助：你使用的是什麼版本的SDK，Vulkan運行時的版本，'vulkaninfo'的輸出顯示什麼可怕，你的圖形驅動程序是最新的？ – skalarproduktraum
