Facebook SDK [4.6.0]重复符号 [英] Facebook SDK [4.6.0] duplicate symbols

问题描述

我正在使用：

FBSDKCoreKit - FBSDKLoginKit - FBSDKShareKit
（4.6.0版）

我不明白为什么今天（直到昨天），我有150个重复的符号，如：

 重复的符号_llvm .embedded.module in：
 /Users/Jacopo/Documents/FacebookSDK/FBSDKCoreKit.framework/FBSDKCoreKit(FBSDKAccessToken.o）
 /Users/Jacopo/Documents/FacebookSDK/FBSDKShareKit.framework/FBSDKShareKit(FBSDKShareOpenGraphObject。 o）
  

我尝试重新导入所有内容，我查看了Build Phase，我更新了我的pod，无法解决$！

编辑：
我刚刚将SDK降级到4.5.1，一切正常。
我使用4.6没有问题，有一天你很奇怪！

编辑：
我尝试了另一个项目使用Facebook SDK 4.6.0，同样的问题！
我今天再次下载了SDK，可能是他们刚刚发布了一个新版本的bug？

显然，SDK只有一个测试版 - > < a href =https://developers.facebook.com/docs/ios/downloads =nofollow> https://developers.facebook.com/docs/ios/downloads

替代方法：
使用Cocoapods工作正常

解决方案

p>这个线程 https://developers.facebook.com/bugs/752177668227984/ 解释你必须在Xcode 7中编译Facebook 4.6.0 SDK来解决问题。在Xcode 7编译之后，它适用于我。

在Facebook iOS SDK 4.6.0中，添加了App Thinning（Bitcode）支持，因此无法遵守Xcode版本低于Xcode 7.0。

I'm using:

FBSDKCoreKit - FBSDKLoginKit - FBSDKShareKit (4.6.0 version)

I can't understand why today (was working till yesterday) I have 150 duplicate symbols like:

duplicate symbol _llvm.embedded.module in:
    /Users/Jacopo/Documents/FacebookSDK/FBSDKCoreKit.framework/FBSDKCoreKit(FBSDKAccessToken.o)
    /Users/Jacopo/Documents/FacebookSDK/FBSDKShareKit.framework/FBSDKShareKit(FBSDKShareOpenGraphObject.o)

I tried reimport everything, I checked Build Phase, I updated my pods, can't solve it!

EDIT: I just downgrade the SDK to 4.5.1 and everything works. I was using 4.6 without problem the other day tho, weird!

EDIT: I tried another project that's using Facebook SDK 4.6.0, same problem! I downloaded again the SDK today, could be that they just released a new version with that bug?

Apparently there's just one beta of the SDK -> https://developers.facebook.com/docs/ios/downloads

WORKAROUND: Using Cocoapods works fine

解决方案

This thread https://developers.facebook.com/bugs/752177668227984/ explains you must compile the Facebook 4.6.0 SDK in Xcode 7 to resolve the issue. After compiling in Xcode 7 it worked for me.

In the Facebook iOS SDK 4.6.0, App Thinning (Bitcode) support has been added and therefore it cannot be complied in Xcode versions lower than Xcode 7.0.
