Undefined Symbol Errors in Xcode (Unity build)

lriley3 · July 18, 2023, 2:26am

Hello!

I am building an iOS game in Unity and just recently updated both my FMOD studio and FMOD studio Unity integration version from 2.0 to 2.02.15.

I’m running into trouble when attempting to build and run my game in Xcode (version 14.3.1). Everything works perfectly in the editor (and also worked perfectly when building with the older version of FMOD), however each time I attempt a build on my iOS device, the build fails.

So far I’ve attempted:

Removing and Redownloading FMOD in Unity
Refreshing my banks from Unity
Relinking my FMOD project within Unity
Rebuilding all platforms in FMOD studio
Changing build locations in Unity (for a new clean build)
Disabling bitcode in xcode.

When I attempt to build on my iPhone, I get 23 errors (listed below), each of them are an “Undefined symbol:” error:

Link UnityFramework (arm64):

When I expand these errors, I get the following:

Hi,

What version of Unity are you using? What operating system are you building the Unity Project on? Using macOS and Unity 2021.3.28f1 I was able to build to iOS without issue.

lriley3 · July 19, 2023, 12:31am

Hi Connor,

I’m using unity 2022.3.2f1 on MacOS Ventura.

lriley3 · July 19, 2023, 12:34am

I recently upgraded Unity from 2020.3.12f1. My project built perfectly every time with that Unity version and FMOD 2.0. but when I upgraded Unity to 2022.3.2f1 and FMOD to 2.01.15, that’s when I started having build errors.

Connor_FMOD · July 19, 2023, 3:27am

I might see an issue, I was testing 2.02.15 as you mention were using

But if the version you are using is

Unfortunately, we no longer support 2.01.

Would it be possible to update to 2.02 and see if you still encounter the error? I will link to our documentation on migrating major version: FMOD Studio | Advanced Topics - Migration FMOD Studio Projects. As well as the Event Updater Tool which aids in converting EventRefs to Studio.EventReferences: Unity Integration | Tools - Event Reference Updater.

Hope this helps!

lriley3 · July 19, 2023, 3:39am

I apologize! I meant to write 2.02.15! I’m on the latest FMOD version.

lriley3 · July 19, 2023, 3:42am

Also, I did run the event updater tool and converted all of my EventRefs to studio.EventRefrences.

lriley3 · July 21, 2023, 1:01am

I just attempted a Xcode install of the same version (14.3.1) and still receiving the same Undefined Symbol errors Knew it was a long shot but thought I’d try just to rule it out. Any other ideas on a possible solution? Or even a bandaid? Thanks!

Connor_FMOD · July 21, 2023, 1:33am

Hi,

Unfortunately, I am still unable to reproduce the issue. Would it be possible to get a stripped-out version of your Unity project that is still having the issue uploaded to your profile, you will have to register a project with us before you can upload it.

lriley3 · July 24, 2023, 4:34am

Got the project uploaded! Appreciate you helping me solve this!

Connor_FMOD · July 25, 2023, 12:23am

Apologies, I forgot to mention to include the FMOD Studio project as well with the following package options:

And please up load the package to your profile.

lriley3 · July 25, 2023, 4:05am

Great uploading the Package now. The full FMOD project is also in the zip file with the unity project, found in the folder called “BallMazeSounds”. Thanks!

Connor_FMOD · July 27, 2023, 2:49am

Hi,

Thank you for providing those projects. Unfortunately, I was still unable to produce the issue and was able to build the project without issue. I would suggest checking the permissions on the libfmodstudiounitypluginL.a in your IOS build Libraries -> Plugins -> FMOD -> platforms -> ios ->lib and make sure it has Read & Write permissions.

lriley3 · July 28, 2023, 2:54am

Hi Connor, thanks for letting me know. I can confirm that the permissions are read/write for that file. Could you share that versions of Unity, FMOD and Xcode you tested with? Do you have any other ideas as to why I may be seeing this issue? Thanks!

lriley3 · July 29, 2023, 1:01am

I’ve also just tried building this on a different computer with identical settings and getting the same errors. Is there any possible way I can escalate this? I’m a bit dead in the water for a big job until I can get this fixed somehow. Really appreciate your help.

lriley3 · July 29, 2023, 1:17am

Also my issue looks related to this thread: Linker error with FMOD Studio Unity iOS fmodstudio11009_v2_patch2 - #4 by mr.caffeine

Is it possible this old bug has resurfaced?

Thanks again!

lriley3 · July 29, 2023, 2:27am

Sorry for the rapid additions! I’ve also just uploaded the Xcode package as well. Could this maybe be helpful to help reproduce the issue? Thanks again!

Connor_FMOD · August 2, 2023, 1:49am

Hi,

Thank you very much for the XCode project.
Using your project I was able to reproduce the issue. A few things I noticed:

Your XCode project has the 2.00 integration library directory included with the 2.02 integration:

Screenshot 2023-08-02 at 11.42.58 am1638×768 141 KB

Could you please delete the lib folder within the FMOD folder and try running the build again?
I noticed your build also includes all the platforms in the FMOD -> platforms folder while my build only included IOS, I was hoping you could explain your build process in detail?
Would it be possible to get the Unity Editor logs after you have made a build uploaded to your profile? There may be more information there.
Thank you for linking the other forum post, however, after investigation it does not seem related.
Hope this helps!

lriley3 · August 2, 2023, 10:53pm

Hi Connor,

Thanks! That last post helped a lot.

So I removed that folder and I was finally able to build to the device. Not sure why the version 2 integration was in there but removing it did solve for the build errors! I’m hoping to build only on iOS and iPad. So not sure how to best remove the other platforms.

Now that it builds however, I’m not getting any audio and when I look in the error log I get the following FMOD related errors:

BankLoadException: [FMOD] Could not load bank '/private/var/containers/Bundle/Application/76B10232-6663-4098-86D2-CD8CE1840B9E/In Your Head.app/Data/Raw/Master.bank' : ERR_PLUGIN_MISSING : A requested output, dsp unit type or codec was not available.

FMODUnityResonance.FmodResonanceAudio:Initialize()
FMODUnityResonance.FmodResonanceAudio:get_ListenerPlugin()
FMODUnityResonance.FmodResonanceAudio:UpdateAudioRoom(FmodResonanceAudioRoom, Boolean)

I’ve attempted to Build the banks from FMOD, and refresh the banks in Unity and am able to run the game with sound in the Unity editor with no problem. Only not getting sound when building in the game.

I found this posting (Resonance Audio Room & Listener not found - #8 by agnardavid) that in the forum that addressed the “Resonance Audio Listener not found in the FMOD project” error and suggest adding some code (to the AWAKE function of a script on a game object:

public class ResonanceRoomHotfix : MonoBehaviour {
void Awake()
    {
        var resonanceBus = FMODUnity.RuntimeManager.GetBus("bus:/{YourResonanceBusNameHere}");
        resonanceBus.lockChannelGroup();
    }

I tried this but still getting those FMOD errors in Xcode.

I feel like we getting close! Thank you for your help and please let me know if there is anything else I can share that can help diagnose and fix this.

Thanks!

Hi,

Good to hear it is building!

In the error logs I can see:

Which indicates that an effect plugin is missing for that platform, I would suggest checking your FMOD Integration settings for any missing plugins:

Alternatively, you can exclude the plugin effect from the desired platform:

More information about exclusion can be read here: FMOD Studio | Glossary - Platform Exclusion.

Hope this helps!
