Mach-O Linker Error When Adding Unit Tests - XCode

I'm trying to add OCUnit tests to an existing project (in XCode 4.6.3). I followed the instructions here - http://twobitlabs.com/2011/06/adding-ocunit-to-an-existing-ios-project-with-xcode-4/ however I'm getting 78 Mach-O errors only when trying to run the tests. I can compile the main target just fine.

One thing to note I have not modified the tests yet, they are just the standard template. I'm not sure example what I'm doing wrong.

One error message

Undefined symbols for architecture i386: "_AudioComponentFindNext", referenced from: l651 in libNuanceSpeechAnywhere.a(libSpeechKit.a-i386-master.o) l652 in libNuanceSpeechAnywhere.a(libSpeechKit.a-i386-master.o)

Here is a screen shot of a bunch of the errors.

Solution

  • You have to add AudioUnit framework to your project first and then rebuild it.

    This is how you add frameworks to your project.
