Unity Cloud Build (iOS) linker errors

[Chris Foulston]

Hi,

Having quite a lot of trouble trying to compile my project on Unity Cloud Build for IOS.

I'm aware that cocoapods are not supported on UCB. So I've followed the steps outlined here: https://stackoverflow.com/questions/41896479/firebase-xcode-linker-command-error-using-firebase-unity-sdk/43260825#43260825

Now, creating an empty project, importing the SDK and following the above guide, the project will compile!

However, as soon as I start using Firebase classes I get linker errors:

3907:        [xcode] ld: warning: arm64 function not 4-byte aligned: ltmp0 from /BUILD_PATH/ludomade.firebase-sdk.default-ios/temp.4ZXW6g/Libraries/libiPhone-lib.a(unwind_test_arm64.o)

3908:        [xcode] ld: warning: arm64 function not 4-byte aligned: _unwind_tester from /BUILD_PATH/ludomade.firebase-sdk.default-ios/temp.4ZXW6g/Libraries/libiPhone-lib.a(unwind_test_arm64.o)

3909:        [xcode] Undefined symbols for architecture arm64:

3912:        [xcode] ld: symbol(s) not found for architecture arm64

3913:        [xcode] clang: error: linker command failed with exit code 1 (use -v to see invocation)

3914:        [xcode] ** ARCHIVE FAILED **

3915:        [xcode] The following build commands failed:

3916:        [xcode] Ld /BUILD_PATH/Library/Developer/Xcode/DerivedData/Unity-iPhone-diczpkbvenndtrflmfvevjaufsmv/Build/Intermediates/ArchiveIntermediates/Unity-iPhone/IntermediateBuildFilesPath/Unity-iPhone.build/Release-iphoneos/Unity-iPhone.build/Objects-normal/arm64/zakstorm normal arm64

3917:        [xcode] (1 failure)

I haven't modified any framework or dll metadata in Unity. I simply imported the packages, wrote a custom PostProcessScript to add missing frameworks, -ObjC, etc.

The features I'm using are FirebaseAuth and FirebaseDatabase

I'm kinda out of options here, and I really don't want to go buy a Mac for the simple purpose of compiling my Project.

Any ideas?

[Chris Foulston]

Still struggling with this. Any ideas or hints as to what this might be?

Am I missing some frameworks? My Post process script looks like this:

public class PostProcessHandler {

    [PostProcessBuild]

   public static void OnPostprocessBuild(BuildTarget buildTarget, string pathToBuiltProject) {

        Debug.Log("Post Processing Build Target: " + buildTarget);

        if (buildTarget == BuildTarget.iOS) {

            PostProcessIOS(pathToBuiltProject);

       }

   }

    private static void PostProcessIOS(string path) {

        Debug.Log("PostProcessIOS: " + path);

        // Go get pbxproj file

        string projPath = path + "/Unity-iPhone.xcodeproj/project.pbxproj";

        // PBXProject class represents a project build settings file,

       // here is how to read that in.

        UnityEditor.iOS.Xcode.PBXProject proj = new UnityEditor.iOS.Xcode.PBXProject();

       proj.ReadFromFile(projPath);

        string target = proj.TargetGuidByName("Unity-iPhone");

        proj.AddBuildProperty(target, "OTHER_LDFLAGS", "-ObjC");

       proj.AddBuildProperty(target, "OTHER_LDFLAGS", "-v");

       proj.SetBuildProperty(target, "ENABLE_BITCODE", "NO");

        if (!File.Exists(path + "/GoogleService-Info.plist")) {

            FileUtil.CopyFileOrDirectory("Assets/GoogleService-Info.plist", path + "/GoogleService-Info.plist");

       }

        string guid = proj.AddFile("GoogleService-Info.plist", "GoogleService-Info.plist");

        proj.AddFileToBuild(target, guid);

        proj.AddFrameworkToProject(target, "AdSupport.framework", false);

       proj.AddFrameworkToProject(target, "CoreData.framework", false);

       proj.AddFrameworkToProject(target, "SystemConfiguration.framework", false);

       proj.AddFrameworkToProject(target, "libz.dylib", false);

       proj.AddFrameworkToProject(target, "libsqlite3.dylib", false);

       proj.AddFrameworkToProject(target, "libicucore.tbd", false);

       proj.AddFrameworkToProject(target, "libApp.a", false);

       proj.AddFrameworkToProject(target, "libAnalytics.a", false);

        //Write the project back

        proj.WriteToFile(projPath);

        Debug.Log("PostProcessIOS Complete");

   }

}

The most recent release of the iOS SDK (released at Google I/O '17) contained breaking API changes.  To make matters worse in our 3.0.3 Unity SDK release we ended up releasing a regression that broke how we pin to specific versions of Cocoapods.

You should import the latest Play Services Resolver plugin into your project available here https://github.com/googlesamples/unity-jar-resolver/blob/master/play-services-resolver-1.2.23.0.unitypackage which will fix the Podfile generation for local builds.

In your UCB builds if you're importing the frameworks you need to download the 3.17.0 frameworks and add them to your project instead.

Cheers,

Stewart

We resolve the Cocoapod version pinning issue in the 4.0.0 release of the Firebase Unity SDK.

Release notes here:

https://firebase.google.com/support/release-notes/unity#4.0.0

Please give this a try and let us know if you're still having issues.

Any chance you could share the complete Unity Cloud Build log?  If you can't on this public forum please open a support ticket on http://firebase.google.com/support and share privately there and we'll diagnose the issue.

Are you using Cocoapods in Unity Cloud Build or adding frameworks manually?

A couple of things stand out here:

• Reference to FIRStorageUtils is very odd as we don't actually depend upon the FirebaseStorage framework / Cocoapod.
  
• The reference to FIRDynamicLinks should only occur if you're using either dynamic links or invites in your project.  If you have Cocoapods enabled this should be included automatically, if you're manually including frameworks then perhaps you're not including the FirebaseDynamicLinks framework and it's dependencies?

Cheers,

Stewart

Did you try upgrading to the latest set of iOS frameworks (version 4.0.2)?  That's what we require in the Firebase Unity 4.0.0 SDK.  You can always check the dependencies by looking at the pod dependencies under the *Deps.cs files in the plugin.

Stewart

Ok could you share the complete build log.  If you're seeing link errors then you're missing some frameworks, we can help determine which ones.

Cheers,
