What version of the product are you using? On what operating system?

I'm using a fresh installation of Ubuntu 12.04. with freenect  and newest 
OpenNI driver installed

I'd got the same errors. It helps for me to change #include directive in 
data_capture.hpp to absolute path to freenect.h.
But i can't build this examples, got messages on make:

I understand, it's ld errors, but i don't understand where and how to change 
its paths.

edit CMakeLists.txt, add the path of libfreenect to static path like this will 
solve the problem:

set(LIBFREENECT_LIBS 
$HOME/myStacks/freenect/libfreenect/build/lib/libfreenect.so.0.2.0)
