Linker Error in iOS (duplicate symbols for architecture x86_64)
I keep on getting the following error:
duplicate symbol _llvm.embedded.module in:
/Users/name/Documents/FacebookSDKs-iOS-20150910/FBSDKCoreKit.framework/FBSDKCoreKit(FBSDKApplicationDelegate.o)
/Users/name/Documents/FacebookSDKs-iOS-20150910/FBSDKCoreKit.framework/FBSDKCoreKit(FBSDKServerConfiguration.o)
ld: 102 duplicate symbols for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I've tried deleting the FBSDK and reinstalling, but that has not work. I also suspect that the fact that I'm bridging the framework into Swift may be the problem. My bridging header contains the following:
#ifndef EggCrush_Bridge_h
#define EggCrush_Bridge_h
#import <FBSDKCoreKit/FBSDKCoreKit.h>
#endif
My AppDelegate.swift file imports FBSDKCoreKit.
There are no other linker flags.
I'm running Xcode 6.3.2 and building a project for iOS 8.3
How to clear this error up?
Answer
If not mistaken, you are using the sdk which just released by Facebook at September 10th, 2015 which named as FacebookSDKs-iOS-20150910.zip. Try to use sdk that released at August 13th, 2015 which named as FacebookSDKs-iOS-20150813.zip and report to Facebook about the duplication problem if you can. Thank you.
