functions do seem to be there for ios and windows, just not for Linux. (or am i missing something? a directive?)
others demos work.
i was looking at playing with instance extensions, so this function is, coincidentally, the very one i was looking at.
Hello @splace , we've been recently changing the way how to initialize the surface, basically we wanted to remove platform-depended code from the library, because for desktop platforms (Linux / Windows / OS X) it is provided by corresponding GLFW / SDL2 libs. On iOS and Android there is no such thing, so we do it manually.
The vulkancube is the most updated example, see https://github.com/vulkan-go/demos/blob/master/vulkancube/vulkancube_glfw/main.go#L26-L33 for example.
Please note that vulkandraw is more ancient and was the first thing I done with Vulkan API, and then I created some boilerplate framework called asche and vulkancube examples uses its pattern to initialize itself.
I should migrate vulkandraw as well..
I don't have an Android toolchain set up so I can't fix the Android build now (and I definitely can't do anything on iOS) but you basically just have to replace those two function calls with GLFW or some other means.
working. background flickers but i see this is low level and so not surprised.
