I'll update the current HaikuPorts recipe to the latest one.
GHOST requires SDL2, i built without it, but it cannot draw the UI, so i had to enable the SDL2 output.
It starts in full-screen, tried to resize, but it doesn't works. So i cannot give you any nice Haiku with Blender screenshot.
The SDL2 output not realible, as it forgets to update the window content. MAybe it requires extra patching. Somebody can look into it.
You can find my preliminary recipe and patchset here: https://github.com/haikuports/haikuports/pull/1130
Any test would be really appreciated. (BTW, i built it outside of HaikuPorter, so the recipe haven't tested yet, i suppose it is broken right now, will fix later)
The Haiku backend for GHOST should be updated to eliminate the SDL from the requires...
Edit: My latest recipe compiles fine on my laptop. If somebody interested, can test it already.
