    Hi, I have same problem, I don't know how to enable vulkan in QT GUI.

    When run configurate said:

    Qt Gui:
       Vulkan ................................. no
    

    Also, when I run the test (/usr/local/Qt/5.10.1/Src/config.tests/qpa/vulkan) compiling good, but throw core exception the ./vulkan generate.

    I have install Vulkan sdk in /usr/local/VulkanSDK/1.0.68.0/x86_64 and enviroment:

    VULKAN_SDK=/usr/local/VulkanSDK/1.0.68.0/x86_64
    VK_LAYER_PATH=/usr/local/VulkanSDK/1.0.68.0/x86_64/etc/explicit_layer.d
    PATH=/usr/local/VulkanSDK/1.0.68.0/x86_64/bin:/home/jose/bin:/home/jose/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/local/VulkanSDK/1.0.68.0/x86_64:/snap/bin
    
    

    And when I open the Samples in QT (/usr/local/Qt/Examples/Qt-5.10.1/vulkan/hellovulkanwindow) build error in:

    /usr/local/Qt/Examples/Qt-5.10.1/vulkan/hellovulkanwindow/hellovulkanwindow.cpp:51: In file included from ../../vulkan/hellovulkanwindow/hellovulkanwindow.cpp:51:0:
    
    Line  51 is: #include "hellovulkanwindow.h" 
    

    Thank.

      You need to tell configure where the sdk is. Please read the comment from SGaist.

          You need to run configure and pass arguments, for example:

          configure -I $VULKAN_SDK/include -L $VULKAN_SDK/lib -v -feature-vulkan

            The bash said:

            ERROR: Feature 'vulkan' was enabled, but the pre-condition 'libs.vulkan' failed.

            And $VULKAN_SDK is correct folder.

              @SGaist Since I tried to run the example project Hello Vulkan Cubes but it just signaled this error:

              Failed to load vulkan: Cannot load library vulkan: (vulkan: cannot open shared object file: No such file or directory)
              initInstance: No Vulkan library available
              Failed to create platform Vulkan instance
              Failed to create Vulkan instance: 0
              

              Regarding the latest status of Vulkan feature supporting in the prebuilt version for Linux, do we have it already enabled for Qt 5.15?

              Thank you.

                From your error message do you have the Vulcan dependencies installed on your system ?

                  Yeap, this is my vulkaninfo command output and I also have VULKAN_SDK set in QtCreator environment variables, thus I could build the example fine, but it just failed at runtime:

                    What did you install on your system for the Vulkan part ?

                      I just have the Vulkan SDK in a local folder and install this NVIDIA driver Linux 455.26.02, which supports VK_KHR_ray_tracing extension from this link:
                      https://developer.nvidia.com/vulkan-driver

                        It would be nice to have more details about the SDK like the version you have, the way you got it and installed it, etc.

                          Yeah, so my Vulkan SDK version is 1.2.154.0 from their official page:
                          https://vulkan.lunarg.com/sdk/home#linux

                          I just extracted to a folder then set VULKAN_SDK to its path.
                          I actually tried with two of my latest current Linux NVIDIA driver as the proprietary 455 and the Beta one 455.26.2.

                          So I doubt that in order to run Vulkan examples by Qt, should I install the Vulkan using sudo apt install vulkan-sdk, which I might dread will conflict with the NVIDIA driver. I remember having some bad experience with it.

                            @Tadinu said in How to configure for Vulkan?:

                            Failed to load vulkan: Cannot load library vulkan: (vulkan: cannot open shared object file: No such file or directory)

                            Have you try setting updating LD_LIBRARY_PATH variable to reflect the proper location of the Vulkan library(ies)?

                              Yeah, I would normally avoid updating LD_LIBRARY_PATH. So I added this to ~/QT/Examples/Qt-5.15.1/vulkan/hellovulkancubes/hellovulkancubes.pro file:

                              LIBS += -lvulkan -L<PATH_TO_VULKAN_SDK>/1.2.154.0/x86_64/lib
                              

                              And it works!

                              Thanks for your advice!

                                I found an interesting piece of information that

                                -recheck-all
                                

                                is needed if it has been configured before.
