Question by DaveOrAstroDave · Feb 21, 2012 at 10:21 PM · iosunity 3.5linker

Mach-O Linker error __Z21NotifyFramerateChangei

Has anyone upgraded to Unity 3.5 and seen the following error?

Undefined symbols for architecture armv7:

"__Z21NotifyFramerateChangei", referenced from: __Z18SetTargetFrameRatei in libiPhone-lib.a(Player.o) ld: symbol(s) not found for architecture armv7 clang: error: linker command failed with exit code 1 (use -v to see invocation) I had a few other linker errors that were apparently caused by needing to link against additional frameworks we had not been using (iAD, CoreVideo, and CoreMedia). This is the last one and I can't seem to sort out the cause. Thanks!

Yes, I am having the same type of problem, except all my linker errors come from "Register$$anonymous$$ono$$anonymous$$odules.cpp", tons of new methods were added to the "RegisterAllStrippedInternalCalls()" function inside the .cpp file, and I get over 200 "Undefined symbols for architecture armv7" errors.

I'm sorry this doesn't help you at all, but you're definitively not the only one having troubles with Unity 3.5, and so far I haven't been able to get ANY help from anyone regarding these linker issues:

I really hope someone from Unity can help out with these issues.
