Addthis in iOS7 64bit

Question

I am developing my iOS app and using Addthis library but error.

error message:

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_AddThisSDK", referenced from:
      objc-class-ref in MyViewController.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Answer 1

If "libAddThis.a" doesn't have 64-bit support built in, that's why you are currently seeing the "Undefined symbols for architecture x86_64" error.

You won't be able to support 64-bit in your application, at least until AddThis updates their SDK to support 64-bit iOS.

So for the time being you should:

1) turn off "arm64" from the "valid architectures" & "architectures" in your app's build settings

2) e-mail the AddThis support people (e.g. via the "Post A Question" link on their iOS SDK page)and tell them to update their SDK to support 64-bit iOS.
