Hi!

I’ve being trying to make use Cloud Build services to compile a mobile project for iOS without success. The error is the following (copy-paste from the log):  
21841: ▸ Linking SuperCasual  
21842:❌; Undefined symbols for architecture armv7  
21843: \> Symbol: \_FMOD5\_System\_GetUserData  
21844: \> Referenced from: \_System\_FMOD5\_System\_GetUserData\_m3137485471 in Bulk\_Assembly-CSharp-firstpass\_1.o  
21845: ❌; ld: symbol(s) not found for architecture armv7  
21846: ❌; clang: error: linker command failed with exit code 1 (use -v to see invocation)

I am forgetting to configure something? I was successful when building at Cloud Build for Android.  
Would someone know what’s the issue?

Many thanks for any help.

Hello Eduardo,

Have you followed the instructions in our documentation on building to iOS?
