$ sudo apt-get install libboost-all-dev swig
$ git clone https://github.com/myriadrf/gr-limesdr
$ cd gr-limesdr
$ mkdir build
$ cd build
$ cmake ..
$ make
$ sudo make install
$ sudo ldconfig
see:
https://wiki.myriadrf.org/Gr-limesdr_Plugin_for_GNURadio
note:
The original examples provided in the gr-limesdr plugin are not optimised for the
lime sdr MINI. They require some hacking.
