Estimote SDK的未定义符号链接器失败 [英] Undefined symbol linker failure for Estimote SDK

问题描述

我试图将Estimote SDK 3.0包含到我的项目中，但是出现以下链接错误:

I am trying to include the Estimote SDK 3.0 into my project, but i am getting the following linking error:

Undefined symbols for architecture arm64:
  "_OBJC_CLASS_$_ESTBeaconRegionWrapper", referenced from:
      objc-class-ref in EstimoteSDK(ESTSecureBeaconManager.o)
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我已将框架添加到构建阶段"，并检查框架搜索目录设置是否包含目录.

I have added the framework to the 'Build phase' and checked that the framework search directory setting contains the directory.

我从Estimote下载了示例应用程序，它使用了相同的框架(也就是我从中进行复制的框架)，并且构建良好.我看不出任何明显的差异.

I downloaded the example App from Estimote, and it used the same framework (that is where I copied it from) and that build fine. I can't see any obvious differences.

我该如何找出问题所在?

How can I figure out what is wrong?

我正在使用Xcode 6.2. 我正在为iPhone 6(所说的体系结构arm64，armv7，armv7s)构建.在下面的问题之后，我为armv7s进行了构建，并且得到了相同的错误(对于armv7s).因此，链接框架肯定存在问题.

I am using Xcode 6.2. I am building for an iPhone 6 (said architectures arm64, armv7, armv7s). After the question below I build for armv7s, and I get the same error (for armv7s). So there must be a problem linking the Framework.

我删除了-ObjC'Other linker flag'，因为将其添加到Estimote项目中会产生相同的错误.但是现在我得到了很多错误:

EDIT 2: I removed the -ObjC 'Other linker flag', as adding that to the Estimote project generates the same error. However now I get a lot more errors:

添加了Security.framework之后，似乎又走了一步:

With the Security.framework added it seems to make another step:
