Enable ARC for theos build system

Question

I'm currently using the theos build system to write applications and tweaks for jailbroken iPhones. Is there a way for me to enable automatic reference counting for specific projects with theos?

I've Googled and tried to decipher the theos makefiles, but I haven't been able to find anything.

Answer 1

I'm not going to unaccept the above answer, because I suspect that this might just have to do with having different versions of theos, and the answer above definitely put me on the right track to finding what I needed. It turns out, at least for my version of theos, the environment variable to set is

ADDITIONAL_OBJCFLAGS = -fobjc-arc

(ADDITIONAL_CFLAGS is also an option, but I don't think there's an opportunity where it matters whether you enable ARC on straight-C code anyways).
