Re: LInker errors where there were none before

I have managed to get it working, but the reason is something of a mystery.
Xcode 9 showed the same problem, so that wasn’t it. I created a new project and just added the CCToneGenerator class to it (which is where the calls to Audio Toolbox are made). It compiled, linked and worked fine.
I worked through the build settings for each to see what differed. The only one was deployment target - 10.8 for the failing build, 10.13 for the working one. Changing it to 10.13 compiled, linked and worked fine. The earliest deployment target that works is 10.10. This is the mystery - when I previously built this project it targeted 10.8 and that worked fine. The APIs in question are marked as being available from 10.6.
For this project, targeting 10.10 as a minimum is not a problem, but I can’t understand why it can’t target 10.8 as before.
