Can I use volk + vulkan-hpp about volk HOT 4 CLOSED

for other who will search for this. There is volk-like mechanism in vulkan hpp which allows to not link to vulkan-loader and use vulkan-headers instead.

As far as I know, if you use vulkan.hpp you don’t need volk - vulkan.hpp should have support for both dynamically loading functions from device and for some (?) extensions:

https://github.com/KhronosGroup/Vulkan-Hpp/blob/master/README.md#extensions--per-device-function-pointers

If you need to use extensions that vulkan.hpp doesn’t provide you can try to use volk and vulkan.hpp together but I suspect it will not go that well.

AFAIK volk allows me to compile without requiring that the end user has Vulkan available (I can use Vulkan if I find it), also AFAIK Vulkan.hpp would require the DLL/.so to run.

Am I correct?

Yes, that's correct - if you use volk, you don't get a link-time dependency to Vulkan Runtime so you can detect this dynamically (if volkInitialize fails) and fall back to a different graphics API. I'm not sure OTOH if vulkan.hpp provides comparable functionality...
