C++ from SpeakHere in iPhone app

I've made a template app where I've grabbed the recording part of the SpeakHere example and removed the file handling part, but I'm struggeling to get the C++ part of the app working right. As soon as it enters the C++ class, it gets syntax errors. If I don't import the header files from C++ (and then of course don't use the code) into my Objective C classes, all works fine. I cannot see the difference between how I'm doing it and the example is doing it. Can you see the difference?

I've posted the entire code here: http://github.com/niklassaers/testFFT

The build errors I get are:

Any idea what's going on here?

You are indirectly including the C++ headers into plain Objective-C code (.m) - that won't work, you have to use Objective-C++ (.mm) all the way or encapsulate the C++ classes in Objective-C classes using opaque pointers.

One problematic chain:

• Classes/MainViewController.m, plain Objective-C, includes
• RecorderLink.h, includes
• AQRecorder.h, which is C++
