CsPaintDemo crashes

[palim]

Hi,

first I want to thank the copperspice team for the free (as in freedom and as in beer) access of your code and examples.

Despite I'm no developer and having very poor knowledge of C++ I am interested in the Vulkan demo of the rotatable copper pot that comes with cs_paint.

After successfully building cs_paint (with a warning), when I execute the binary, a window opens for a moment and closes with an error:

Code: Select all

user@computer:/opt/copperspice/cs_paint/bin$ ./CsPaintDemo 
vk::Device::allocateDescriptorSetsUnique: ErrorOutOfPoolMemory, exiting
Segmentation fault (core dumped)

Here some output from the compilation including the mentioned warning:

Code: Select all

user@computer:/opt/copperspice/cs_paint$ cmake -G "Ninja" -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/opt/copperspice/cs_paint_lib /opt/copperspice/cs_paint

I'm working with Ubuntu 20.04.2 and installed the most recent vulkan drivers from LunarG (1.2.170) for my OS. I wonder if I did something wrong or if someone other can reproduce the issue and can help me to get the demo running.

Thanks in advance and cheers,
Ben

Thanks for looking at CsPaint. We are currently not seeing these issues on any other system, and would like to investigate this further with you.

Can you provide some additional debugging information?

• A description of the graphics hardware on your system (things like Integrated GPU, discrete GPU, driver version)
• The output of the "vulkaninfo" command
• Any warnings or issues seen while running the "vkcube" program
