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. In orderto avoid defining these variables each time you enter a session, you may want to add these three lines to your $HOME/.bashrc file.
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).
NOTE: At this moment (Dec. 2011), perftools seems to be not working properly in Ubuntu 11.10. See http://code.google.com/p/google-perftools/issues/detail?id=386
