Question Facebook SDK fails due to CS0619 errors

Hi all,


I'm working on getting the Facebook Unity SDK into a Unity project. It builds perfectly on my local computer, both for iOS and Android. However, when building the projects on Unity Cloud Builds it fails (both for iOS and Android), and it seems like it's due to the following error:

7804: [2022-09-29T11:47:58Z - Unity] Assets/FacebookSDK/Examples/Scripts/ConsoleBase.cs(243,42): error CS0619: 'ScreenOrientation.Landscape' is obsolete: 'Use LandscapeLeft instead (UnityUpgradable) -> LandscapeLeft'

Also, Unity's own ad library seem to trigger the same error:

6101: [2022-09-29T11:47:37Z - Unity] Library/PackageCache/com.unity.ads@4.2.1/Runtime/Advertisement/Platform/Editor/Placeholder.cs(83,47): error CS0619: 'ScreenOrientation.Landscape' is obsolete: 'Use LandscapeLeft instead (UnityUpgradable) -> LandscapeLeft'

These errors are marked in red, so it indeed seems like these are the reason why it fails. However, while the code is obsolete, this should ONLY be a warning, and allow Unity Cloud Build to continue.

Anyone knows how to fix this?

Thank you VERY much in advance for your help!


Kind regards,
Uffe Flarup

Hi @JeffDUnity3D

Thanks for your help on this. I can see that something was fixed in 2022.2.x, but it hasn't been backported yet. Also, I can fix the issue in the Facebook SDK, but I still get an error from the Unity ads SDK:

15: [2022-10-03T12:44:29Z - Unity] Library/PackageCache/com.unity.ads@4.2.1/Runtime/Advertisement/Platform/Editor/Placeholder.cs(83,47): error CS0619: 'ScreenOrientation.Landscape' is obsolete: 'Use LandscapeLeft instead (UnityUpgradable) -> LandscapeLeft'

Any suggestion to how I get around a package from Unity that doesn't build? There are no further updates to that package.

Thank you very much for your help!

Kind regards,
Uffe

 

After updating to version 4.4.1 of the Unity Ads package I know have made some progress getting Facebook SDK to build using Unity Cloud Build. It builds perfectly fine LOCALLY, but on UCB it still fails, now with the error pasted below.

Any suggestions to why this fails on UCB, but works locally?

Thank you very much in advance.

Kind regards,

Hello @Barb-UnityAds

Thank you very much for helping looking into this! The project builds fine (and runs fine on device as well) when building on my local computer. I'm using Unity 2020.3.40f1 and XCode 14.0.1 (14A400).

Kind regards
Uffe

 

Hi @Barb-UnityAds I just tried with XCode 14.0 (14A309) on my local computer, and it works fine here.

 

Hi again @Barb-UnityAds I have tried with different XCode configuration on UCB, but still no luck getting the Facebook SDK to build together with my game. On my local computer I have also just tested using XCode 14.1, and that works fine.

Do you have any suggestions to why Facebook SDK doesn't build on UCB?

 

Hi again @Barb-UnityAds

I just did a completely clean git clone, followed by importing into Unity from scratch, and building everything from scratch. And it still worked locally.

After inspecting the latest logs from UCB, it's still the following lines that gets my attention:

18337: <span class="log_warning_line">[2022-11-02T14:00:48.114Z] - 7.1.1.2.4.2 - INFO: &#9656; <span class="log_warning">&#9888</span>;️  ld: arm64 function not 4-byte aligned: _unwind_tester from /BUILD_PATH/multiscription-aps.draw-pass.ios-2020-facebook/temp20221102-5904-1xhiiqg/Libraries/libiPhone-lib.a(unwind_test_arm64.o)</span>

18338: 

18339: <span class="log_error_line">[2022-11-02T14:00:49.816Z] - 7.1.1.2.4.2 - INFO: &#9656; <span class="log_error">&#10060</span>;  ld: symbol(s) not found for architecture arm64</span>

18340: 

18341: <span class="log_error_line">[2022-11-02T14:00:49.825Z] - 7.1.1.2.4.2 - INFO: &#9656; <span class="log_error">&#10060</span>;  clang: error: linker command failed with exit code 1 (use -v to see invocation)</span>

I did notice the following forum post : https://answers.unity.com/questions/1805667/arm64-function-not-4-byte-aligned-unwind-tester-fr.html

He has the same build error, and he's building on virtual machines. Is that maybe the reason why?

 

Hi @Barb-UnityAds

Unfortunately we still have the problem. All the "working" builds are from our main branch, but our Facebook branch is still failing on iOS (but works on Android though). The latest failing build is here : https://dashboard.unity3d.com/gamin.../buildtargets/ios-2020-facebook/builds/17/log

But it fails with the same errors as last time.

Any help at figuring out why this fails on Unity Cloud Build is much appreciated.

Kind regards,
Uffe Flarup

 

Hi @Barb-UnityAds

Just tried switching to XCode 14.1 on UCB, but still the same result (and we're using Cocoapods 1.11.3 btw). The email you mention is no longer active. Which email would you like me to reach out to instead?

Thanks a lot in advance.

Uffe
