Undefined symbol linker failure for Estimote SDK

Question

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)

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

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.

How can I figure out what is wrong?

EDIT: 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.

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:

[Edit 3:] With the Security.framework added it seems to make another step:

Have you checked whether there is new version for the library you use? And can you give some information about your app architecture & valid architecture in build settings and the version of the XCode you use? (It seems that the library does not support Arm64.) — ondermerol, Mar 20 '15 at 09:57
I added the Xcode version. It doesn't build for armv7s either, so there must be a problem in the linking. Probably something small/simple I have to do or have forgotten. — Luuk D. Jansen, Mar 20 '15 at 11:11
Hey, Piotr from Estimote here—we actually consider this a bug and are working on a resolution, stay tuned for a bug-fix release. — heypiotr, Mar 26 '15 at 09:20
Hi @heypiotr, please see my solution at the bottom, I think that solved it for me, don't need the Security. Just old build settings on an existing project. — Luuk D. Jansen, Mar 26 '15 at 09:32
Nice! We had a few more people reporting that changing these settings helps. We've just pushed 3.0.2 live though, which should fix this issue without having to change anything (: — heypiotr, Mar 26 '15 at 16:56

Thanks to the various hints above I went through the whole build file, and found the flag that was different. It is 'Enable Modules', and was set to 'No' in my build settings.

I just downloaded https://github.com/Estimote/iOS-SDK their SDK and successfully included it in a sample project.

Under 'Build Settings' in 'Build Active Architecture Only' set 'Debug' to YES

Also Try In 'General' tabs

Add framework under 'Link Frameworks and Libraries'.
Add framework under 'Embedded Binaries'.

Make sure that EstimoteSDK.framework is actually present at its original location, you may have accidentally deleted it.

Some of the OPs errors are missing `Security.framework` dependency. How did you manage to integrate it without needing it? Did you actually use any of the framework's functionality? – trojanfoe Mar 20 '15 at 11:53
I am only started to integrate it, but am using some of the classes already. The Security.framework is not present in the example App either. – Luuk D. Jansen Mar 20 '15 at 12:02
I must be something in my build settings so. Just don't know where to start, this project is 3 years old, so there might be changes in there inherited from much earlier iOS versions. – Luuk D. Jansen Mar 20 '15 at 12:02
Interesting, when I add the Security.framework I get different (or less?) errors, see above edit3. Any other suggestions? – Luuk D. Jansen Mar 20 '15 at 12:28

Looking at the podspec it specifies -lc++ flag to be added to OTHER_LDFLAGS. If you don't have this flag set, maybe that could cause such problems.

I think I see what the problem is. I have -ObjC set. If I set that on the Estimote project it fails too, so it must be in that corner somewhere. I can't remember why I needed to add -ObjC. If I remove it from my exiting project I get a whole lot more errors of Estimote. I will post the full error list above. – Luuk D. Jansen Mar 20 '15 at 11:38

This is fixed in Estimote SDK 3.0.2! (:
