= OsmoSDR Gnuradio Source =

Primarily gr-osmosdr supports the OsmoSDR hardware, but it also offers a wrapper functionality for [http://tetra.osmocom.org/trac/wiki/Funcube_Dongle FunCube Dongle], [http://files.ettus.com/uhd_docs/manual/html/build.html Ettus UHD] and [http://sdr.osmocom.org/trac/wiki/rtl-sdr rtl-sdr] radios. By using gr-osmosdr source you can take advantage of a common software api in your application(s) independent of the underlying radio hardware.

Build process

'''The gnuradio source requires a recent gnuradio (>= v3.5.3) to be installed.'''

Please note: prior pulling a new version from git and compiling it, please do a "make uninstall" first to properly remove the previous version.

Building with cmake: {{{
git clone git://git.osmocom.org/gr-osmosdr
cd gr-osmosdr/
mkdir build
cd build/
cmake ../ -Wno-dev
make
sudo make install
sudo ldconfig
}}}

NOTE: The source block will appear under 'OsmoSDR' category in GRC menu.

Automated installation

Marcus D. Leech has kindly integrated the forementioned build steps into his gnuradio installation script at [http://www.sbrac.org/files/build-gnuradio]. This is the most user-friendly option so far.
