_objc_retain", referenced from:__ARCLite__load error in Xcode 4.4

Question

I've recently upgraded to Xcode 4.4 and have been using it for some Mac App Store submissions. Two worked fine but the third gave this error:

Undefined symbols for architecture x86_64:
  "_objc_retain", referenced from:
      ___ARCLite__load in libarclite_macosx.a(arclite.o)
     (maybe you meant: _objc_retainedObject)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

ARC is turned off so I don't know where this reference is coming from, or how to get rid of it. I've tried the usual clean/build cycle but to no avail.

Any thoughts?

Answer 1

I think you should use the SDK 10.6 on Xcode 4.4,right? If so, please Change "Implicitly Link Objective-C Runtime Support" to "NO".

Answer 2

Is your base sdk lower than 5.0? I'm using Xcode4.5, and get the same error when i building with iOS 4.2.After I changed it to iOS5.0(or above), the error disappeared.

I'm sorry,you talked about Mac app.But i think the reason may be the same. OK，i found an answer: Change "Implicitly Link Objective-C Runtime Support" to NO may work.
