Problem when building the Juce's AU Plugin Demo

MacOSX and iOS
1

I everyone, 

 

I'm trying to build the Juce Audio Unit plugin demo, but I get 20 Errors, 

 

Here is a screen :

 

 

 

I think that I miss a library that include "Audiocomponentplugininterface" or something else...

 

I've tried during 4 hour different core audio sample classes, it doesn't work...

My folder is in my application/Content/Developer/Extras.

 

 

Thanks in advance and sorry for my english, I'm french.
