iOS - Xcode: linker command failed with exit code 1, using firebase plugin

[neeravBlacklight]

ErrorLog.txt

Operating system: macOS Operating system version: High Sierra 10.13.4 Unity version: 2018.1.4f1 Xcode: 9.4.1 (9F2000)

Exported iOS xcode project for device sdk. When building in Xcode for an actual device

Error: linker command failed with exit code 1 attached are the error logs.

Then i tried without the firebase plugin, removed the firebase plugin from unity, exported xcode project then tried building and the Build was successful.

I've followed the exact steps mentioned. Don't know where i'm going wrong. Any help would be much appreciated.

Thanks.

Hey all,

Sorry for the delay in response. Not entirely sure why you might be seeing this problem, but I have a couple questions that can hopefully narrow it down for us.

In your Unity project, under "Assets/Plugins/iOS/Firebase", do you have "libFirebaseCppApp.a", along with whichever APIs you have also included. Are there other libraries in that folder that don't have that naming convention?

In the generated Xcode project, in the project view, are those libraries present in "Unity-iPhone/Libraries/Plugins/iOS/Firebase"? Then, if you select "Unity-iPhone", then "General", at the bottom is "Linked Frameworks and Libraries". Are "libFirebaseCppApp.a" and the other libraries present in that list?

[nickreffitt]

Hi @a-maurice

Thanks for the follow up, my issue was due to importing two versions of GoogleIOSResolver

Using v1.2.53.0 alone allows me to build and run on iOS.

Thanks!

[a-maurice]

Hi @nickreffitt

Thanks for the response. That's a bit concerning, as part of what the resolver should be doing is clearing out old versions of itself. You can read more about it how it works here: https://github.com/googlesamples/unity-jar-resolver#unity-plugin-version-management

Just to clarify, after you imported the newer version of the Firebase SDK, did you have both 1.2.53 and 1.2.69? In normal circumstances a dialog box should pop up once the code compiles stating that it detected old versions, and asking if you want to delete them. Just wondering, could you check from the toolbar Assets > Play Services Resolver > Version Handler > Settings. By default it should have "Enable version management", "Prompt for obsolete file deletion" and "Use project settings" checked, and if those first two aren't, that could explain why you ran into this issue.

Hey, sorry for the late response the "libFirebaseCppApp.a" was not present in the "Assets/Plugins/iOS/Firebase". So reimporting the plugin and found that these libs were included. But as soon as the play service resolver completes, these were gone from the "Assets/Plugins/iOS/Firebase".

Also i'm seeing some additional files in the "Assets/Firebase/Plugins/iOS" pfa.

I haven't checked building to iOS after the reimport. Will update on progress.

Thanks

Update: Checked on xcode, do not have those files in the plugin but i can see meta's available, in the folder.

• libFirebaseCppAnalytics.a.meta
• libFirebaseCppApp.a.meta
• libFirebaseCppMessaging.a.meta
• libFirebaseCppRemoteConfig.a.meta

[a-maurice]

Hi @neeravBlacklight

That is definitely odd, I've never encountered that behavior before myself. We do delete older versions of files when new versions are available, so maybe something has been tagged incorrectly, and thus files that shouldn't be deleted are being deleted.

Are there any files other than those .meta files that you listed in the Assets/Plugins/iOS/Firebase directory? Also, if you examine one of those meta files, near the top it should have something like "- gvh_version-5.2.1". What version number are you seeing in that?

As for the files in "Assets/Firebase/Plugins/iOS", those look correct. Basically, those are the C# libraries, while for some reason the C++ libraries in the other directory, that the C# ones use, are being deleted out from under you.

Also, just to be clear, what version of the Unity plugin have you been trying to use?

[neeravBlacklight]

Hey, @a-maurice

Currently i'm on version 5.3.0 I manage to solve the problem by reimporting the .a files for iOS from the plugins that were missing, making sure the play service resolver did not run.

After this on building for iOS i could see the .a files in the xcode project. But, this is a weird issue. Every-time play service resolver runs, it clears the iOS firebase plugins folder. I had to keep a separate copy of the ".a" files just to paste them in the "Assets/Firebase/Plugins/iOS"

[a-maurice]

Thanks for the info @neeravBlacklight

It's good that you have a workaround, but that is definitely still a problem... If you could, could you go to the toolbar's Assets > Play Services Resolver > Version Handler > Settings, and first confirm that it has the default settings ("Enable version management", "Prompt for obsolete file deletion", and "Use project settings" should be enabled, while the other two should not). Then, enable "Verbose logging", and run the Update for it. Presumably in the Console, or the Unity editor logs (https://docs.unity3d.com/Manual/LogFiles.html), it should say something about why it trying to delete those ".a" files.

[Ciaviel]

We are encountering a similar issue with Unity 2018.2.6f1 and Firebase 5.3. We resolved it by manually adding the frameworks, though this seems to be version 5.9 and now crashes on app start with this stack trace:

[stewartmiles]

Similar to https://github.com/firebase/quickstart-unity/issues/209 this may be due to the iOS SDK being broken by an update to the GoogleUtilities pod. Could you give the 5.3.1 release a try https://firebase.google.com/support/release-notes/unity#5.3.1 ?

[Ciaviel]

Tried it out without adding the frameworks manually and still getting (in fact it seems to have gotten worse):

[haroldsati]

Xcode version: 10 Firebase SDK version: 5.3.1 Firebase Component: Auth Unity: 2018.2.11f also try on 2018.2.10

I built a clean version from the 5.3.1 version and AuthExample but is a compilation problem in Xcode. There is no much information about the error, just that code. I Already review all the comments in here, but nothing works for me.

I Hope someone can help me.

[stewartmiles]

@Ciaviel and @haroldsati :

• Is the iOS resolver enabled in your project? If you have errors in your project the plugin may not be loaded which will not generate the Pods file.
• Have you reproduce the issue in our Unity quickstart applications (i.e in this repo?) . It sounds like it, just double checking?
• Which version of Cocoapods is installed on your machine? If it wasn't installed the iOS resolver should have prompted you to install it. e.g On one of my machines, typing pod --version into the console displays 1.5.3.

[haroldsati]

Hi @stewartmiles,

First IOS Resolver:

Second, Yes i am. i am using a AuthExample from here with Firebase 5.3.1

Third Cocoapods:

[jexreffy]

Xcode version: 10 Firebase SDK version: 5.3.1 Firebase Component: App, Functions, Messaging Unity: 2018.2.11f

@stewartmiles I just installed Firebase into my Unity Project for the first time last week. Having the same issue as @haroldsati iOS Resolver and Cocoapods are the same.

[stewartmiles]

@jexreffy similar to what I've mentioned before did you:

• Validate a sample application builds on iOS?
• Check Unity's console logs to see whether the iOS resolver reports any errors installing Cocoapods into the generated project. You can also enable verbose logging in the iOS resolver plugin to see what's going on.

@haroldsati

• Could you enable verbose logging in the iOS resolver plugin and share your Unity logs?

[bobak-ss]

Xcode version: 10 Firebase SDK version: 5.3.1 Firebase Component: Auth Unity: 2018.1.0f2

Same problem here I also tried importing Firebase in an empty unity project and build successfully completed. I reset the project back to the latest working version without Firebase, then I imported Firebase again without any implementations and Xcode builds successfully but after adding Firebase initialization code I can't get to build the project again!

[ozbra]

Xcode version: 10 Firebase SDK version: 5.3.1 Firebase Component: Auth Unity: 2017.4.1f1

I was using Firebase SDK version 5.3.0 and getting working builds until 2 days ago. Both on my machine and cloud build. But when I tried today both on Cloud and my machine, Unity builds it to xCode successfully although I can't get any working build from xCode side. Error message is below.

After this, I've upgraded Firebase SDK to 5.3.1 but the error is still same. I even tried with empty Unity project, Just with Hello Word UI element with Firebase Auth and Firebase Database components, and the error is still same. I have a feeling, everytime there is an update on pod side or Firebase side, older versions are getting effected. Why previously working version get effected by this?

[jexreffy]

@stewartmiles Mea Culpa on my part. I thought I had Cocoapods installed when I did not. Once I got it installed, I can build no problem. My apologies.

[stewartmiles]

Hi everyone,

Before posting "me too" on this thread, we need more information that you're all providing:

1. Turn on verbose logging in the iOS Resolver settings (see Assets > Play Services Resolver > iOS Resolver > Settings)
2. Build for iOS and if the build fails
3. Share your UnityEditor.log (see https://docs.unity3d.com/Manual/LogFiles.html )
4. Share your Xcode version
5. Xcode build logs (so we can see the linker errors etc. reporting exit code 1 is not very informative)
6. Cocaopods version (see https://stackoverflow.com/questions/26677830/how-to-find-out-the-version-of-installed-cocoa-pods?rq=1 )

Thanks, Stewart

[stewartmiles]

I've been chatting with one of our iOS SDK leads and they suggested that you could try deleting the Xcode DerivedData cache and updating to Cocoapods 1.5.3.

i.e

rm -rf ~/Library/Developer/Xcode/DerivedData

then

sudo gem install cocoapods

and finally check that Cocoapods is up to date with...

pod --version

[stewartmiles]

Oh also, if you're using Unity 5.6 and above with the "Xcode Workspace" integration enabled in the iOS resolver, you'll need to make sure you're opening up the .xcworkspace file not the .xcproject file generated by Unity's build process. Unity 'should' open the correct file when you select "build and run".

[ozbra]

I was creating detalied list according to your suggesting up there and after setting verbose on, I figured out there was a missing file. I noticed this after checking Xcode build logs with Verbose on. And missing file is not related to firebase. After solving that, it worked out fine for me.

[bobak-ss]

Xcode version: 10 Unity version: 2018.1.0f2 Cocoapods version: 1.5.3 Firebase SDK version: 5.3.1

In my case the error accures only when I try to build with the simulator so after Unity opens up my project I go to Supported Platforms and I change iphones to IOS then I choose iPhoneX(12.0) simulator and I hit Build button, after a few minutes my builds results in failed. Here is the Xode log file: Xcode_build_on_simulator_Log But when I just try to build the project into my device(iPadMini - ios 9.3.5) the build proccess takes so much time and even waiting for 30 minutes to 1 hour id does not simply finish and sometimes it makes Xcode crash! Here's the Xcode log file for this case: Xcode_build_on_device_Log

• I've checked Assets/Libraries/Plugins/iOS/Firebase and the "libFirebaseCppApp.a" exists.
• My GoogleIOSResolver are the latest version(1.2.92.0) and are the only version in /Assets/PlayServicesResolver/Editor/.
• Cocoapods is installed on my system but I tried the steps @stewartmiles suggested anyways and my 'pod --version' says: 1.5.3
• And yes my unity automatically opens and xcode workspace after I hit build and run.

Here is my UnityEditor log file: Editor.log

I should mention that my simulator does have problems even out side this project because when I tried to run an empty unity project in simulator I encountered the same error as firebase project. I even tried importing Firebase SDK into an empty unity porject and it worked just fine and build on device was successfull! After I imported Firebase to my main project it does work in the unity editor but I can't get it to build on my device!

[stewartmiles]

@babak-ss Unity typically generates projects that only have schemes to build for either a real device or the simulator. To switch to a simulator build:

• Select File > Build Settings menu option
• In the Build Settings dialog switch the target platform to iOS
• Press Player Settings... in the Build Settings dialog.
• In the Inspector (should be visible from clicking Player Settings...) scroll down to Target SDK (in the Other Settings, Configuration section below Target Device) and switch the combo box to Simulator.
• Finally build a project for this target. This will generate a Xcode project that contains schemes which target the simulator rather than a physical device.

If you're going to manually add new schemes you'll need to take care to configure them appropriately. The build log you shared contains quite a few warnings which suggest mis-configured build settings...

warning: The iOS Simulator deployment target is set to 6.0, but the range of supported deployment target versions for this platform is 8.0 to 12.0. (in target 'GoogleUtilities')

warning: Mapping architecture armv7 to i386. Ensure that this target's Architectures and Valid Architectures build settings are configured correctly for the iOS Simulator platform. (in target 'GoogleUtilities')

I don't think this is unity specific. I am getting the same errors after updating firebase in an app without any unity integrations. Happy to provide whatever details would be helpful here.

[stewartmiles]

@liquidise any chance you have a project you could share? We can then pass it over to the iOS SDK team to figure out what's going on. Also, what Xcode version are you using? I'm concerned that we may be seeing problems with bitcode compatibility between Xcode versions for the prebuilt components that we ship.

[liquidise]

@stewartmiles Xcode Version 10.0 (10A255) on Mojave. The project is our business's ios app, so very hesitant to share the uncompiled code en-masse.

[liquidise]

also notable is that the issue is not armv7 specific. If i adjust my deployment targets, i get the same error for arm64:

[bobak-ss]

@stewartmiles Thanks for your response, and sorry for replaying this too late. I finally figured what was the problem, it was not firebase related after all! It seems like I had a big chunk of code inside a try{}catch and for some reason it made xcode freeze.

Hi, I don't know if this is a related issue, but I also had linking errors, specifically one mentioning libplatform.a. Tried all the above suggestions, nothing worked. I then tried unticking the target membership and now it builds ok... How's libplatform.a used ? Is it safe to disable?

ld: warning: Some object files have incompatible Objective-C category definitions. Some category metadata may be lost. All files containing Objective-C categories should be built using the same compiler.
ld: could not reparse object file in bitcode bundle: 'Invalid bitcode version (Producer: '902.0.39.2_0' Reader: '900.0.39.2_0')', using libLTO version 'LLVM version 9.0.0, (clang-900.0.39.2)' for architecture armv7

Xcode Version 9.2 (9C40b)

pod --version
1.5.3

I suppose it doesn't depend on the Xcode version

Xcode Version 9.2 (9C40b)

Xcode 9.2 is incompatible with the Firebase Unity libraries due to a bug in Bitcode compatibility in that version.

The Firebase Unity SDK's minimum supported version is Xcode 9.4.1.

Hello, I have struggled with same error. I did try 'pod install' 'pod update' manually but it did not help.

Xcode version: Version 10.1 (10B61) Unity version: 2018.3.0f2 Cocoapods version: 1.5.3 Firebase SDK version: 5.4.3

Undefined symbols for architecture armv7: "_OBJCCLASS$_FIRMessaging", referenced from: objc-class-ref in libFirebaseCppMessaging.a

unity editor log console output full error output pod file

Update: I update Firebase Analytics and Messaging to 5.4.4 and also fixed pod file:

source 'https://github.com/CocoaPods/Specs.git' source 'https://github.com/CocoaPods/Specs' platform :ios, '10.0'

target 'Unity-iPhone' do pod 'Firebase/Analytics', '5.15.0' pod 'Firebase/Core', '5.15.0' pod 'GoogleAppMeasurement', '5.4.0' pod 'Google-Mobile-Ads-SDK', '~> 7.0' end

But still get same error!

[zendorx]

Bug found, fibase generate invalid pod file, I need manually fix it to setup frameworks.. There is no Messaging framewk in pod file

[stewartmiles]

@zendorx Firebase generates a podfile using the iOS Resolver. Each pod is referenced by a Firebase/Editor/COMPONENTDependencies.xml file in the plugin, if you've removed Firebase/Editor/MessagingDependencies.xml file then the Firebase/Messaging pod will not be added to the generated Podfile.

From what I can fathom, the issues originally reported in this thread have been solved so I'm closing this issue.

I am experiencing the same issue:

I've tried downgrading the firebase pod versions from 5.7 to 4.0 and 3.7, but getting the same error.

Hi ! Have you solved this bug?

[zendorx]

Have you solved this bug?

Hi, I found that Firebase plugin does not generate podfile properly. I have added Admob (or whatever lib you need) manually to podfile after XCODE project generation.

[stewartmiles]

@zendorx what do you mean the Podfile isn't generated properly? What Podfile do you see generated and how is it incorrect?

FWIW: https://github.com/googlesamples/unity-jar-resolver generates the Podfile not the Firebase plugin.
