Dependencies

• GNU Radio v3.7.X

sudo apt-get install gnuradio (3.7.9.1-2ubuntu1)

• Build dependencies (cmake, libboost, swig)

sudo apt-get install cmake libboost-all-dev liblog4cpp5-dev swig

• the python module bitstring

sudo pip install bitstring
or
sudo apt-get install python-bitstring

• Source Block for RTL-SDR dongle http://osmocom.org/projects/sdr/wiki/rtl-sdr

sudo apt-get install gr-osmosdr
or build from source:
sudo apt-get install libusb-1.0-0-dev libusb-dev
git clone git://git.osmocom.org/rtl-sdr.git
cd rtl-sdr/
mkdir build
cd build
cmake ../
make
sudo make install
sudo ldconfig

or you can use the GNU Radio Live Image , which can be written to a USB drive with Unetbootin. It comes with all dependencies except the "bitstring" module, which can be installed with

sudo pip install bitstring

Installation

mkdir build
cd build
cmake ..
make
sudo make install
sudo ldconfig

if you don't see the new blocks in gnuradio companion, click the reload button

without root privileges

put this in your .bashrc file (replace user with your username):

BASE=/home/user/gnuradio-prefix
export PATH=${PATH}:${BASE}/bin
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${BASE}/lib64:${BASE}/lib
export PKG_CONFIG_PATH=${PKG_CONFIG_PATH}:${BASE}/lib64/pkgconfig
export PYTHONPATH=${PYTHONPATH}:${BASE}/lib64/python2.7/site-packages/
export GRC_BLOCKS_PATH=${GRC_BLOCKS_PATH}:${BASE}/share/gnuradio/grc/blocks

this tells gnuradio companion where to find the blocks, and your system where to find the executables

when building use the following cmake command (replace user with your username):

cmake -DCMAKE_INSTALL_PREFIX:PATH=/home/user/gnuradio-prefix ..

now make should install the module to the specified folder, without needing root privileges
