    Hi Halle,

    I am trying out the SaveThatWaveDemo with the sample OpenEars app. I have the other Linker flags set to -ObjC for both Debug and Release. However, I am still getting the following build error:

    Undefined symbols for architecture arm64:
    “_OBJC_CLASS_$_SaveThatWaveController”, referenced from:
    objc-class-ref in ViewController.o
    ld: symbol(s) not found for architecture arm64

    My OpenEars is 2.041.

    How did you add it to the project?

    Just followed the instructions on the web site,
    https://www.politepix.com/savethatwave/

    1. Open up the OpenEars™ Sample App in Xcode. Drag your downloaded SaveThatWaveDemo.framework into the OpenEars™ sample app project file navigator.
    2. Open up the Build Settings tab of your app or OpenEarsSampleApp and find the entry “Other Linker Flags” and add the linker flag “-ObjC”. Do this for debug and release builds.

    Can you install it using the tutorial instructions? It has screenshots for the required target settings, etc.

    Yes, I installed using the tutorial instructions.

    Actually the issue is resolved. The linker errors are in the tests build target in the sample app. After deleting the tests target, the sample app builds fine with SaveThatWaveDemo.
