I briefly mentioned previously about using gnu radio on Linux or OSX. Today I will walkthough the installation process on OSX.
First install MacPorts if you have not already done so: http://www.macports.org.
First install the rtl-sdr drivers:
port install gr-osmosdr
Now the latest version of gnuradio uses variants:
port info gnuradio Password: gnuradio @3.7.1 (science, comms) Sub-ports: gnuradio-devel, gnuradio-next Variants: debug, docs, full, grc, jack, orc, portaudio, python26, [+]python27, qtgui, sdl, swig, uhd, universal, wavelet, wxgui Description: GNU Radio Software Defined Radio (SDR): This port is kept up with the GNU Radio release, which is typically updated every few months. Homepage: http://gnuradio.org/ Build Dependencies: cmake Library Dependencies: boost, cppunit, fftw-3-single, pkgconfig, python27, py27-numpy, py27-cheetah Runtime Dependencies: py27-scipy Conflicts with: gnuradio-next, gnuradio-devel Platforms: darwin, macosx License: GPL-3 Maintainers: email@example.com, firstname.lastname@example.org
So if we issue:
port install gnuradio +full
All necessary packages and components will be installed!
You can now use gnuradio in Python and use gnuradio-companion. To construct radio based programs
You can also use GQRX, to visualise the radio spectrum to identify and tune into specific frequencies.
UPDATE: OSX Mavericks
Since the update to Mavericks GNURadio was temporarily broken, looking at the Macports Buglist the Team apparently had problems with swig and boost. I can confirm that as of this weekend the problem has been rectified, and once again we can enjoy radio and playing with RTLSDRs on OSX Mavericks.
After upgrading Mavericks remember to perform the following:
- Update Xcode to Verison 5.0.2+
- Update Macoprts verision 2.2.1 (OS X 10.9 Mavericks)
- For minimum support of MacPorts, you need the Command Line Tools, which can be installed using “xcode-select –install”
- Run “sudo port update”
- Then either:
- “sudo port upgrade outdated”
- If you have not install GNURadio before “sudo port install gnuradio +full”
