I’ve tested Open Morrowind on Haiku and it’s working “fine” on my NUC when I disable most of the graphical options (6 FPS but it’s playable ^^)
Then I’ve tried to compile it via Haikuports and I discovered a strange thing :
It’s compiling OK however, when launching the program, it’s stuck when I click on one of the options of the menu.
Looking at the binary it’s not really the same size that “OpenWM” available via HaikuDepot :
So I’m a bit surprise why I should have a difference in the program behavior and its size, any idea ?
I’m trying to have a playable app once compiled via HaikuPort 
(don’t tell me to use the version from HaikuPort as I would like to start from the compiled version on my NUC )
