GNU Radio Installation Instructions 1. Access the terminal window by clicking Applications then Accessories, and finally Terminal. 2. Then type the following commands in the terminal mkdir 3.0.3-usb-fix (this creates a directory called gnuradio) cd 3.0.3-usb-fix (this changes the directory to the one just created) 3. Type the following command line in the terminal to download gnuradio. This subversion is used because the version available under the Download link will not recognize the USRP. svn co http://gnuradio.org/svn/gnuradio/tags/releases/3.0.3-usb-fix 4. Copy the following command line into the terminal and press enter. This command line is taken from the Ubuntu build guide under “Install required packages” sudo apt-get -y install g++ automake1.9 libtool python-dev fftw3-dev libcppunit-dev libboost-dev sdcc libusb-dev libasound2-dev libsdl1.2-dev python-wxgtk2.6 subversion guile- 1.6 libqt3-mt-dev python-numpy-ext • A message may appear telling the user to remove the –y from the commands to be entered in steps 4 and 5. If the message appears remove the –y and repeat steps 4 and 5. • Also a prompt may appear asking the user to continue, simply press Y and hit enter 5. Copy the following command line into the terminal. This command was taken from the Ubuntu build guide under the heading “Install optional packages” with the exception of the added packages gnuplot, r-base, gsl and swig sudo apt-get -y install gkrellm wx-common libwxgtk2.6-dev alsa-base autoconf xorg-dev g77 gawk bison openssh-server emacs cvs usbview octave gnuplot r-base gsl swig 7. Copy the qwt-5.0.2.tar.bz2 into your home directory. The tarball can be obtained by entering the following command in the terminal wget http://superb-east.dl.sourceforge.net/sourceforge/qwt/qwt-5.0.2.tar.bz2 8. To compile and install the qwt type the following tar jxf qwt-5.0.2.tar.bz2 cd qwt-5.0.2 qmake make sudo make install 9. Copy the 3.0.3-usb-fix.tar.gz into your home directory. The tarball can be accessed by using the following command svn co http://gnuradio.org/svn/gnuradio/tags/releases/3.0.3- usb-fix.tar.gz 10. To bootsrap, configure, and compile gnuradio enter the following commands tar xzvf 3.0.3-usb-fix.tar.gz cd 3.0.3-usb-fix ./bootstrap ./configure make make check 11.Now run the following command to install GNU Radio sudo make install FYI: To uninstall GNU Radio type the following sudo make uninstall 12. Now the USRP can be enabled to work under Linux by entering the following commands in the terminal sudo addgroup usrp sudo addgroup <YOUR_USERNAME> usrp echo 'ACTION=="add", BUS=="usb", SYSFS{idVendor}=="fffe", SYSFS{idProduct}=="0002", GROUP:="usrp", MODE:="0660"' > tmpfile sudo chown root.root tmpfile sudo mv tmpfile /etc/udev/rules.d/10-usrp.rules Replacing YOUR_USERNAME with your actual username. If unknown type in the command whoami 13. Plug in the USRP if you have not already done so and reboot the computer. 14. Now to test the throughput of the USB port on your computer. Running properly at full speed the system rate should be 32MB/s. The following commands are an example to test if the USRP has been installed correctly. cd gnuradio-examples/python/usrp ./benchmark_usb.py 15. The operating system may be upgraded by entering the following command lines in the terminal sudo apt-get -y upgrade sudo apt-get -y dist-upgrade 16.Reboot the computer and you are now ready to use GNU Radio! Simple exercise that does not use the USRP: cd gnuradio-examples/python/audio ./dial_tone.py 17. We now need to add a line to “octaverc” so that octave can use GNU Radio files: cd /usr/share/octave/2.1.73/m/startup sudo gedit octaverc If you receive an error message stating that there is no such file, go to Places -> Search for Files and enter “octaverc”; remember to change Look in folder to the File System. Put this in the file and save, replacing <YOUR_USERNAME> with your login name. LOADPATH = [ ":/home/<YOUR_USERNAME>/3.0.3-usb-fix/gnuradio- core/src/utils", LOADPATH ]; .
