How to set up the compilation environment and build GNSS-SDR in Ubuntu:
* Install GNU Radio:
- Downloading, building and installing GNU Radio and all its dependencies is not an easy task. We recommend to use Marcus Leech's build-gnuradio script, which automatically does all the work for you. In a terminal, do:
$ wget http://www.sbrac.org/files/build-gnuradio
$ chmod a+x build-gnuradio
$ ./build-gnuradio
This can take a while (up to two hours to complete, depending on the system), and installs the latest versions of UHD and GNU Radio in your system, including all their dependencies.
- Set up some system variables needed by the GNSS-SDR build system:
where /path/to/gnuradio is the folder in which you invoked build-gnuradio. If you don't want to define these variables each time you enter a session, you can add these two lines to your $HOME/.bashrc file.
* Install other libraries used by GNSS-SDR:
- Download, compile, and install the Armadillo linear algebra library
The full stop separated from "cmake" by a space is important. CMake will figure out what other libraries are currently installed and will modify Armadillo's configuration correspondingly. CMake will also generate a run-time armadillo library, which is a combined alias for all the relevant libraries present on your system (eg. BLAS, LAPACK and ATLAS).
