Hi !

I update my unity package and my soundbank with the last version of FMOD (1.05.00).

When i try to compile on xCode (with all cache clear), i have a compile error :

Undefined symbols for architecture armv7:  
“\_FMOD\_Studio\_VCA\_IsValid”, referenced from:  
RegisterMonoModules() in RegisterMonoModules.o  
“\_FMOD\_Studio\_EventDescription\_IsValid”, referenced from:

“\_FMOD\_Studio\_CueInstance\_IsValid”, referenced from:  
RegisterMonoModules() in RegisterMonoModules.o  
“\_FMOD\_Debug\_Initialize”, referenced from:  
RegisterMonoModules() in RegisterMonoModules.o

I try to delete all of my FMOD files in unity and reimport the package (to have a clean import) but i still have the error.

I tried to download an older package (1.04.07) and compile on xCode. There was no error but i didn’t have any sound (maybe because of my soundbank version).

Is it a bug of FMOD 1.05.00 or i made an error somewhere ?

Thanks !

Thanks for the report, part of the iOS build system for Unity hadn’t been updated for some API changes. Here is prerelease package of 1.05.01 which resolves this issue:

ftp://upload:upload@ftp.fmod.org/fmodstudio10501\_prerelease.unitypackage

Apologies for the inconvenience.
