Undefined symbols for architecture i386 - Updated Scringo

Question

I know this has been asked before and I have been through the many answers but I am still unable to resolve this after hours of trying.

I updated my Scringo and Facebook SDK's and I am now facing this problem:

Undefined symbols for architecture i386:
  "_OBJC_CLASS_$_FBWebDialogs", referenced from:
      objc-class-ref in Scringo
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I have check all my framework dependancies and they are all there. I have no idea to check which .m file is supposed to be included in the "Compile Sources" in Build Settings.

Any insight would be greatly appreciated.

Answer 1

Make sure you're using the latest Facebook SDK (or at least 3.5) when using the latest Scringo versions. It is probably some mismatch in the library versions.

Answer 2

Select your target from TARGETS and go to Build Phases > Compile Sources > Link Binary With Libraries section. Check if Scringo Framework is there. If not add it.

If it is, then it looks like your updated Scringo SDK is not compiled for i386 architecture which iOS Simulator has.
