If you get an 'ITPP Not Found' error:

$ sudo apt-get install libitpp-dev or # Download itpp-4.3.1.tar.gz $ tar xvzf itpp-4.3.1.tar.gz $ cd itpp-4.3.1/ $ mkdir build $ cd build $ cmake .. $ make $ sudo make install $ sudo ldconfig

If you get a "RTL Support not enabled/compiled, falling back to Pulse Audio Audio Input." error:

$ sudo apt-get install librtlsdr-dev

and recompile.

Plug in RTL SDR.
