###### Build FMCOMMS2 based SDR Hardware support (OPTIONAL):
Install the [libiio](https://github.com/analogdevicesinc/libiio.git) (>=v0.11), [libad9361](https://github.com/analogdevicesinc/libad9361-iio.git) (>=v0.1-1) libraries and [gr-iio](https://github.com/analogdevicesinc/gr-iio.git) (>=v0.2) gnuradio block. For example in Ubuntu 16.04 follow these instructions (based on https://github.com/blurbdust/blurbdust.github.io):
~~~~~~
$ git clone https://github.com/analogdevicesinc/libiio.git
$ cd libiio
$ mkdir build
$ cd build
$ cmake ..
$ make
$ sudo make install
$ sudo ldconfig
$ git clone https://github.com/analogdevicesinc/libad9361-iio.git
$ cd libad9361-iio
$ mkdir build
$ cd build
$ cmake ..
$ make
$ sudo make install
$ sudo ldconfig
$ git clone https://github.com/analogdevicesinc/gr-iio.git
$ cd gr-iio
$ mv include/gnuradio/iio include/iio
$ rm -r include/gnuradio
$ sed -i 's/gnuradio\/iio/iio/g' CMakeLists.txt
$ sed -i 's/gnuradio\/iio/iio/g' swig/*
$ sed -i 's/gnuradio\/iio/iio/g' include/iio/*
$ sed -i 's/gnuradio\/iio/iio/g' lib/*
$ sed -i 's/gnuradio\/iio/iio/g' python/iio/*
$ sed -i 's/from\ gnuradio\ import\ iio/import\ iio/g' grc/iio_pluto_sink.xml
$ sed -i 's/from\ gnuradio\ import\ iio/import\ iio/g' grc/iio_pluto_source.xml

$ sed -i 's/from\ gnuradio\ import\ iio/import\ iio/g' grc/iio_fmcomms2_source.xml
$ mkdir build
$ cd build
$ cmake ..
$ make
$ sudo make install
$ sudo ldconfig
~~~~~~
Then configure the gnss-sdr to build the `Fmcomms2_Signal_Source` and `Plutosdr_Signal_Source`:
~~~~~~
$ cmake -DENABLE_FMCOMMS2=ON ../
$ make
$ sudo make install
~~~~~~
or configure only `Plutosdr_Signal_Source`:
~~~~~~
$ cmake -DENABLE_PLUTOSDR=ON ../
$ make
$ sudo make install
~~~~~~
With `Fmcomms2_Signal_Source` you can use any SDR hardware based on fmcomms2, including the ADALM-PLUTO (PlutoSdr) by configuring correctly the .conf file. The `Plutosdr_Signal_Source` offers a simplier manner to use the ADALM-PLUTO because implements only a subset of fmcomms2's parameters valid for those devices.
