I recently download the latest Juce tips and its version with modules etc… The JuceDemo works fine on mac but when I try the iOS build, some compilation errors appear in some files that belong to the juce\_audio\_devices module (juce\_mac\_CoreMidi.cpp and juce\_audio\_devices.cpp). I, for exemple, get “MIDIEndPointRef” was not declared in this scope.  
Does that could come from a missing framework?

Thanks again

No problems compiling it here… Which SDK are you using?

I’m running on a Mac OSX Lion 10.7.3 with the juce version 2.0.19. The base SDK used when I try to run the Juce Demo for iOS is “iOS 4.3”

Maybe try the latest SDK then. I think it’s 5.1

I finally managed to get a successful building by adding “#include \<CoreMIDI/MIDIServices.h\>” to juce\_mac\_CoreMidi.cpp, the CoreMIDI framework’s header containing the MIDIEndpointRef definition.  
Is it normal?

That’s strange… I wonder why I don’t seem to need that? Oh well! I’ll add that extra include, there’s no harm in having it! Thanks!
