I compiled the openbci2ft application on the Raspberry Pi without any problem. The openbci2ft application interfaces the OpenBCI board with the FieldTrip buffer, which is a network transparent interface to real-time EEG data and which supports MATLAB, Python, Java and C/C++ interfaces to the data stream.
The openbci2ft application is implemented as ANSI-C application, as is the FieldTrip buffer library. It compile without too much hassle on all platforms (tested so far on OS X and RPi). You can find the source code in the FieldTrip github repository, where you can also download compiled binaries for the tested platforms.
To get started processing real-time EEG data, please check the documentation.
