I just discovered Haiku and I’m having a lot of fun getting used to it. I thought it would be really fun to play some Pathways Into Darkness and Marathon Infinity, so I tried to compile alephone1.3 and I got really close! It seems that I’m running into a compilation error related to sdl2_net.
Welcome to the forum! Have you tried looking up those two missing constants feeding into ioctrl? They may just have a different name on Haiku. (I’m basing the idea that they are constants by the fact that the names are all uppercase.)
Edit:
Here’s a thought: the networking code on Haiku is largely based on that of BSD. That may give you the search term you need.
Thanks for the welcome I’m just starting to learn programming but I’m mighty fine with a search engine. Let me see what I can dig up with your hint of inspiration!
