I just added the latest Facebook SDK code from Github to my project. Because I’m using ARC, I used their supplied shell script to build the static library. I added it to my project and made sure the static library is being linked, but I’m receiving this linker error:

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

Here are the linker settings:

App linker settings

Any ideas?

    The head revision has some recent changes that seem to have broken ARC builds (static library). The static library builds ok, but then when used in my project I get the linker errors. What I did to fix the problem was to revert to the previous version of the Facebook sdk and these linker errors went away.

    See https://github.com/facebook/facebook-ios-sdk/commits/master

    I used the version checked in on the 24th Feb (not 25th Feb, sorry Jason Clark!)
