[9fans] Porting software from other operating systems (Namely Mac OS 9) to Plan 9

[9fans] Porting software from other operating systems (Namely Mac OS 9) to Plan 9

Hello all! Nightdive Studios recently released the source code for the Mac OS9 / PowerPC version of System Shock 1. Besides being among my favorite games, it's also one of the first properly 3D games to exist, and getting it running on Plan 9 would be a fun and interesting project in my estimation. The source code (https://github.com/NightDive-Studio/shockmac) is written in C for the most part, with the notable exception of a bit of C++ and the tiniest sliver of objective-c, each of which is possible to convert somewhat inelegantly back into ansi C. It has conveniently separated out the portion of the code that is specific to Mac, so my admittedly uninformed hope is that if I could simply modify this code and replace any references to Mac OS 9 event handlers and resources, I could compile it on plan 9.  Are there any resources available to port these event handlers or resources, or any known projects that span across mac os 9 and plan 9, that I could use as references?

Apologies as well if this topic had already been created; after a brief search, I couldn't find any other questions asking this same thing, so I figured I'd produce my own and if I had missed something in my search someone might point me in the right direction.

hi radiuspi,

here are a few links about porting to plan 9. hopefully these are helpful
for you as they are to me. you did not mention 9front, so if you don’t know
about it i recommend learning about it, as it provides many helpful
programs you don’t have in 9legacy. the third link is a man page for the
coding style of 9front, which may be helpful for rewriting that C++ and obj
C.

Hi,

I’m not sure if you’ve seen it but there seems to be a multi platform port with some cleanup already underway, it might be easier to start from that: https://github.com/Interrupt/systemshock
