Linker (Id) Error>Undefined symbols for architecture arm64 on Xcode compile...any help appreciated

Target Platforms Mobile
1

My settings are
Metal
IL2CPP
Universal
full .NET2.0

Xcode project was compiled using Unity 5.5.1f1, with Symlink and Debug settings.

Am using two 3rd party assets

-Vuforia
-AVProVideo for iOS

In Xcode my iOS deployment target is iOS 8.0.
Half way thru the Xcode compile I get the following error.

Here is a similar issue on stackoverflow

ld: symbol(s) not found for architecture arm64

This type of error usually means that thee managed code in the project has an extern static method in C# named AVPPluginSetDebugLogFunction. That method should be a native method which is part of a native static library in the project.

IL2CPP requires that all extern static methods be resolved a link time. If they are not found by the native linker, errors like this will occur.

It might be the case that these methods should not exist for an iOS build. If so, the extern static methods where they are defined in C# code should be surrounded with #if !UNITY_IOS statements to avoid compiling them.

3

ok thanks so just to confirm
I should do a search for ‘AVPPluginSetDebugLogFunction’ in Xcode and surround with #if !UNITY_IOS compilation statements?

4

No, search for that method in the C# code in the project, not in the generated C++ code in Xcode. You will also need to do the same for the other methods mentioned in these errors.

But more generally, do you know what these methods are? Do they come from the source code of a third-party plugin? If so, maybe there is something wrong with the build of that plugin. Maybe it has a native part that is missing.

5

Ok yes so I did a search and its part of the AVPROVideo iOS plugin.
But I’ve compiled and deployed to iOS several demo scenes from this plugin without issue.
Seems strange and unlikely that it is problematic now.
But I see
[DllImport(PluginName)]
just before where it is declared.

And cross referencing the Assts>Plugins>iOS folders with the master project for this plugin I see that libAVProVideoiOS.a is missing!
Question
When you export a project by selecting a scene with dependencies, are ALL plugins also included in the exported custom package? Or do they have to be manually copied?

also
Shouldn’t Unity throw an error when the Xcode project is being created if there is a missing plugin-dll?

Thanks again for your feedback. Unlikely I would have solved without:)

6

The error message is pretty clear about the cause in this case. The reason why the native code from the AVPROVideo iOS plugin is not available might be a bit more difficult to track down. Can you compare the Xcode project from one of the demos that works with the Xcode project in this case? Maybe a library is missing from the linker step.

7

Yes as mentioned libAVProVideoiOS.a was missing.

8

Sorry, I don’t know the answer to this question.

Unity doesn’t really know about missing plugins until the native linker runs. There are a number of complex cases that Unity cannot handle well, so this is a best (maybe bad) way to be notified.

I’m glad that you were able to track down the cause of the issue.

Hello.

I am using Unity 2017.3.0f3 and Facebook SDK v7.11.0.

ld: symbol(s) not found for architecture arm64

Can anyone help in this regard please ?

@muneebatta

I’m not familiar with the Facebook SDK, but it looks like the build in Xcode is missing a native library. Does the Facebook SDK have a native library associated with it?

11

Thank-you Josh for your prompt reply.
I am not sure about Facebook SDK’s association with a native library. Can you please guide me on how to check this?

I have been working with Facebook SDK ever since. But this latest Facebook SDK v7.11.0 with Unity 2017.3.0f3 and xCode 9.2 is giving me these errors.

Even if i create a new Unity project and just import Facebook SDK and nothing else and make a build, it’s giving me this error in xCode.

I can’t seem to find a solution to this anywhere else.

12

I have the same problem, but in Unity 2017.2.1f1 (Also FB SDK 7.11 and XCode 9.2)

13

It looks like there are a number of missing native methods. For example, the error:

“_initScreenPosition”, referenced from:

_CanvasFacebook_initScreenPosition_m2309792883 in Bulk_Facebook.Unity_0.o

_CanvasFacebook_Init_m2337299698 in Bulk_Facebook.Unity_0.o

indicates there is an extern static method in C# code named initScreenPosition. There should also be a corresponding native method of the same name, but that native method is not found.

Try searching the C# code in the Facebook SDK for “initScreenPosition”. You should see a DllImport attribute on that method which indicates which native library has the native code for that method. If the DllImport attribute uses a library named “__Internal” that means the initScreenPosition native function should be statically linking into the final binary.

14

Same Problem here with Unity 2017.3.0f3, Xcode 9.2 and FB SDK 7.11

What worked for me was to step back to FB SKD 7.10.1 from https://developers.facebook.com/docs/unity/downloads
In my Unity Project i deleted both the FacebookSDK and the PlayServicesResolver-Folders and (re)imported the facebook-unity-sdk-7.10.1.unitypackage
After entering the AppID again via Menu-Facebook-Edit Settings i was able to build for iOS

You’re right, 7.10.1 compiles for me too - thx… So it appears to be a FB SDK bug, I’ve reported it to FB, FWIW…

Thanks for your help. I’ll try facebook sdk 7.10.1 now

17

Same problem over here going Unity to Xcode, and switching to FB sdk 7.10.1 worked for me. Thanks everyone!
