Linux Template Fails on Pipeline Creation

[shepard47]

I've built the engine on Linux but I get a segmentation fault when I launch the template (the same happens with the ImGui example). This is the gdb backtrace output:

(I have an intel haswell cpu if that's related to the problem.)

What is your GPU? First thing try to update graphics driver.

[shepard47]

My drivers are all up-to-date and I have an integrated Intel GPU. 00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09) (prog-if 00 [VGA controller])

[turanszkij]

I still don't know what is your GPU, only that it is integrated Intel. For example is it a Intel 620? This seems to be that the driver cannot compile the shaders. Probably the shaders contain some instructions that specific Intel GPU doesn't support.

[shepard47]

I'm sorry, it's Intel HD Graphics 4400.

[turanszkij]

Thanks. I think for a GPU that old, you will be out of luck with this engine. Here it reports that it only supports Vulkan 1.0: https://www.techpowerup.com/gpu-specs/hd-graphics-4400.c2470 This engine requires support for Vulkan 1.3 at least.

[shepard47]

I think what you've found is on Windows. On Linux, there's a different implementation as far as I know and my Vulkan version is 1.3. Vulkan Instance Version: 1.3.246 But you might be right that this implementation won't run the engine because I also get this message: MESA-INTEL: warning: Haswell Vulkan support is incomplete I was just curious if I could make the engine work on this older machine but thank you for your help.

[shepard47]

I built the engine in debug mode and I found the problem: Assertion features_1_2.descriptorIndexing == VK_TRUE' failed

[turanszkij]

Thanks for checking. If this is the case, unfortunately you are out of luck because we rely on hardware that supports descriptor indexing (also called bindless resource). The error reporting will be improved in the future.
