I’m getting the following error in Xcode when trying to build for tvOS with FMOD 2.01.00

“\_FMOD5\_Thread\_SetAttributes”, referenced from:

Thanks for bringing this to our attention, it is a new api that was missed from the definition file. You can get around this by deleting/commenting-out the `Thread_SetAttributes` in `fmod.cs`.

We should have this fixed for the next release.

Thanks, I ended up just rolling back to the last stable version
