How to configure for Vulkan?
-
@SGaist thank you, you're right and I need to read help more carefully.
So I successfully configured and output gives me:
Qt Gui: Vulkan ................................. yesI build the library with
make, next installed it withmake installbut still can't make it work. This time it tells me/usr/local/Qt-5.10.1/include/QtGui/QVulkanFunctions:1: error: qvulkanfunctions.h: No such file or directoryIndeed this file is not there. But why? For example,
qvulkanwindow.hwas installed, andQVulkanFunctionstoo. But what's wrong withqvulkanfunctions.h?Upd: I manually copied this header to installation folder and finally was able to compile the example. Looks like somebody forgot to add this header to installation file list.

Did you re-run configure from a clean state ?
What I recommend is to use out of source builds so if you need to start over you just nuke the folder you use and start from fresh. That way you keep the sources clean.
-
Yes, did it twice. Looks like an error in generated make file. Anyway, everything working now, thank you.

Hi, I have same problem, I don't know how to enable vulkan in QT GUI.
When run configurate said:
Qt Gui: Vulkan ................................. noAlso, 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/binAnd 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.
-
@nikitablack How? I don't use QT before.
-
You need to run
configureand pass arguments, for example:configure -I $VULKAN_SDK/include -L $VULKAN_SDK/lib -v -feature-vulkan -
@SGaist Since I tried to run the example project
Hello Vulkan Cubesbut 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: 0Regarding 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
vulkaninfocommand output and I also haveVULKAN_SDKset 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 supportsVK_KHR_ray_tracingextension 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
1.2.154.0from their official page:
https://vulkan.lunarg.com/sdk/home#linuxI just extracted to a folder then set
VULKAN_SDKto its path.
I actually tried with two of my latest current Linux NVIDIA driver as the proprietary455and the Beta one455.26.2.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)?
