I've been following up on the forum threads but I haven't had time to actually read the code yet. (And the last time I checked, the arc2c executable gave me a segfault.)
The current arc2c output assumes that you have a proper Boehm GC installation, but since I can't seem to get a good install here (prolly something to do with being AMD64 again) I just disable the GC for now.
I finally got arc2c to work (without GC as you suggested). One note though: apparently arc2c relies on rm-global.arc, but doesn't load it by default. So under the current version of the compiler, 'compile-file will error until you (load "rm-global.arc").
Oops. Must have forgotten to add it to arc2c.arc then ^^. Unfortunately I won't be able to fix this until maybe 7 hours from now T.T, haha, I'm in the office ^^
The thing about GC working: well, you need to somehow download the development version of Boehm GC, and, well, that's what's stopping me for now T.T
