error: ‘VK_API_VERSION’ was not declared in this scope

Hi,

i was trying to build the chopper demo on Arch Linux using Nvidia 364.16 driver.
The cmake configuration went ok, but while building with make an error occured.

This was the cmake output:

$ cmake ..

And this are the last lines of the make output:

HI
I've just pushed an update that removes the deprecated referrence to VK_API_VERSION.
Please can you pull VulkanAppContext.cpp again and try.

Many Thanks

Chris

That solved it. But now i got another error with linking.

Ok, thats strange as it doesn't use assimp.
Quick workaround for now is to install assimp (asset importer)
sudo apt-get install assimp

That did it. Thank you. Got it working.
