ZeroLink: unknown symbol

    I have some sample code that I am trying to compile. I have identified
    the following extract to be the culprit - it compiles fine (using
    Xcode 2.4.1) - so I must have the correct headers etc.

    deviceNameAsCFString =
    CFStringCreateWithCString(kCFAllocatorDefault, deviceName,

    kCFStringEncodingASCII);


    Yet on execution I get this error:-

    ZeroLink: unknown symbol '_kCFAllocatorDefault'
    Abort trap

    I have tried enabling/disabling the ZeroLink option and it always
    compiles without errors yet I get the execution error.

    What is the problem here?

    How are you disabling ZeroLink? From the bottom of the 'build' menu?

    I used Project->Edit Project Settings->Build, selected the "Debug"
    configuration, and unticked "ZeroLink" option.
    I hadnt noticed the option at the bottom of the build menu which I see
    was set to "Allow ZeroLink". I have now unticked it and I do indeed
    get link errors. I would have thought that the project settings would
    be sufficient!

    Target settings override project settings, maybe that's what happened.
