= Building GNU Radio on Ubuntu Linux =

'''Note: this page is not update anymore, as the build-gnuradio script does all the work on Ubuntu systems. Check this page only for reference for older systems and as long as the script doesn't work for Ubuntu 18.04!'''

This page describes how to build and install GNU Radio from source on Ubuntu Linux. It is intended to be a step-by-step guide for the entire process. Nevertheless, you should carefully read it through before doing anything.

Before you continue, please consider using the build-gnuradio script. It works fine on Ubuntu and Fedora and is sufficient for most users. Continue reading if you really want to go through all the steps of the build process manually.

The build-gnuradio script can also take care of individual steps here. You should really, really consider using it.

GNU Radio works great on all Ubuntus from 10.04 upward. It is also possible to install GNU Radio on older releases of Ubuntu (see below); however, we may not be able to provide sufficient support for legacy OS.

Installation Overview
Installing GNU Radio on any recent Ubuntu is easy and requires the following steps:


 * 1) Install the pre-requisites
 * 2) Get the GNU Radio source code
 * 3) Configure, compile and install GNU Radio
 * 4) Configure USRP (optional)

Instructions for each of these steps are given below. The build-gnuradio script can do all of these steps in one go, or every one individually.

Install the Pre-Requisites
The following packages are required for compiling various parts of GNU Radio on Ubuntu. These packages can be installed via the command, your favourite package manager (e.g. Synaptic) or using the command lines given in the next section.


 * Development Tools (need for compilation)
 * g++
 * git
 * make
 * cmake
 * sdcc (from &quot;universe&quot;)
 * guile
 * ccache (not required, but recommended if you compile frequently)


 * Libraries (need for runtime and for compilation)
 * python-dev
 * SWIG
 * FFTW 3.X (libfftw3-dev)
 * cppunit (libcppunit-dev)
 * Boost 1.35 (or later, but not 1.46, 1.47 or 1.52)
 * GSL GNU Scientific Library (libgsl0-dev)
 * libusb and libusb-dev
 * ALSA (alsa-base, libasound2 and libasound2-dev)

 * WX GUI
 * for the WX GUI components you need to install python-wxgtk2.8 and python-numpy


 * QT GUI
 * for the QT GUI components you need to install PyQT4, PyQwt5 for Qt4, QT-OpenGL, Fontconfig, Xrender and Xinput (python-qt4, python-qwt5-qt4, libqt4-opengl-dev, libqwt5-qt4-dev, libfontconfig1-dev, libxrender-dev, libxi-dev).


 * Video-SDL
 * for Video-SDL you need to install the Simple DirectMedia Layer development libraries (libsdl1.2-dev)


 * Polyphase Filter Bank examples
 * for the examples in gnuradio-examples/python/pfb to work you need to install python-scipy, python-matplotlib, and python-tk


 * Other useful packages
 * doxygen (for creating documentation from source code)
 * octave (from &quot;universe&quot;)

Install Dependencies
The following command line scripts will install all the required dependencies. Before running them you should ensure that the Universe repository are enabled in &quot;Software Sources&quot;.

To execute the script copy &amp; paste the relevant command line into a terminal.

If you have an Ubuntu newer than 11.04, use the build-gnuradio script.

export PYTHONPATH=/opt/qt/lib/python2.7/dist-package

Saucy Salamander (13.10)
Saucy Salamander has a particular problem with PyQT and PyQWT. First, apt-get the following packages to get start. We will then manually build and install PyQT and PyQWT to get around the issue.

sudo apt-get -y install git-core cmake g++ python-dev swig \ pkg-config libfftw3-dev libboost1.53-all-dev libcppunit-dev libgsl0-dev \ libusb-dev libsdl1.2-dev python-wxgtk2.8 python-numpy \ python-cheetah python-lxml doxygen libxi-dev python-sip \ libqt4-opengl-dev libqwt-dev libfontconfig1-dev libxrender-dev \ libgruel3.6.1 If you have PyQWT installed already, remove it:

Make sure SIP is installed:

We'll set up a separate directory to install into to make it keep it nicely separated from anything else (in case Ubuntu fixes this problem).

First, set up your environment

Edit ./bashrc by adding or amending the following variables:

export PATH=/opt/qt/bin:$PATH export LD_LIBRARY_PATH=/opt/qt/lib:/usr/local/lib:$LD_LIBRARY_PATH export PYTHONPATH=/opt/qt/lib/python2.7/dist-packages:$PYTHONPATH export PKG_CONFIG_PATH=/opt/qt/lib/pkgconfig:$PKG_CONFIG_PATH Either restart the terminal or reset your environment:

Download and install PyQt version 4.10.3

http://pyqwt.sourceforge.net/download.html

$ tar xzf PyQwt-5.2.0.tar.gz  $ cd PyQwt-5.2.0/configure $ ./configure.py -Q ../qwt-5.2 --module-install-path=/opt/qt/lib/python2.7/dist-packages/PyQt4/Qwt5 $ make $ sudo make install If you've already built GNU Radio, first delete CMakeCache.txt in the top build directory. You should then only have to 'make clean' in gr-qtgui.

Run cmake and make like you would normally. With the environmental variables pointing to the new PyQT and PyQWT versions we've installed all gr-qtui displays and widgets should work properly now.

Raring Ringtail (13.04)
Note: At release, Ubuntu defaults the 'libboost-all-dev' package to libboost-*.49, which is incompatible with GNURadio. Thus, until the Ubuntu default Boost install catches up, you must manually specify 'libboost1.53-all-dev'.

Installing GNU Radio
You can do this automatically via:. Or manually:

git clone --recursive http://git.gnuradio.org/git/gnuradio.git or

git clone --recursive git://git.gnuradio.org/gnuradio.git Configure and build GNU Radio:

cd gnuradio mkdir build cd build cmake ../ make Notes:


 * If you want to use GNU Radio with a USRP, see UHD instructions
 * By default GNU Radio will be installed under /usr/local - for installing in a custom directory see this section

After successful build you should run the GNU Radio software self-check (does not require USRP):

make test If any test or tests do not work, GNU Radio might still function properly, but it might be wise to look in the email archives for a fix or to write the email list. If writing to the email list, please include the OS type, OS version, and CPU type (e.g. via &quot;uname -a&quot;), anything special about the computer hardware, software versions (gcc, g++, swig, sdcc, etc) and how installed (standard or non-standard package, source). You can find some useful tips for asking questions under Reporting Errors.

Now install GNU Radio for general use:

sudo make install You are now ready to use GNU Radio. You can try to execute the dial_tone.py example (/usr/local/share/gnuradio/examples/audio/dial_tone.py) or the gnuradio-companion.

Configuring USRP support
''This section is only relevant if you have a USRP1 that you want to use with GNU Radio. You may already have done this if you have installed UHD .''

Ubuntu uses udev for handling hotplug devices, and does not by default provide non-root access to the USRP. The following script is taken from directions, and sets up groups to handle USRP via USB, either live or hot-plug

sudo addgroup usrp sudo usermod -G usrp -a echo 'ACTION==&quot;add&quot;, BUS==&quot;usb&quot;, SYSFS{idVendor}==&quot;fffe&quot;, SYSFS{idProduct}==&quot;0002&quot;, GROUP:=&quot;usrp&quot;, MODE:=&quot;0660&quot;' &gt; tmpfile sudo chown root.root tmpfile sudo mv tmpfile /etc/udev/rules.d/10-usrp.rules At this point, Ubuntu is configured to know what to do if/when it detects the USRP on the USB, except that &quot;udev&quot; needs to reload the rules to include the newly created one. The following might work, but if it doesn't then rebooting the computer will.

sudo udevadm control --reload-rules or

sudo /etc/init.d/udev stop sudo /etc/init.d/udev start or

sudo killall -HUP udevd You can check if the USRP is being recognized, by examining /dev/bus/usb after plugging in a USRP. Using the command:

ls -lR /dev/bus/usb | grep usrp should result in one or more lines (one for each USRP) reading something like:

crw-rw 1 root usrp 189, 514 Mar 24 09:46 003 Each device file will be listed with group 'usrp' and mode 'crw-rw'.

Once you've verified that the USRP is available to Ubuntu, now it is time to verify that GNU Radio works with the USRP. While &quot;usrp_benchmark_usb&quot; might not return a full 32 MB/s of throughput, the script should at least run properly; if not, either GNU Radio didn't make correctly or the USRP isn't accessible. From the &quot;gnuradio&quot; directory, verify that all of the following work:


 * Python interface to the USRP; provides a rough estimate of the maximum throughput (quantized to a power of 2) between the host computer and the USRP.

cd gnuradio-examples/python/usrp ./usrp_benchmark_usb.py
 * C++ interface to the USRP; provides a good estimate of the maximum throughput (non-quantized) between the host computer and the USRP.

cd usrp/host/apps ./test_usrp_standard_tx ./test_usrp_standard_rx You are now ready to use GNU Radio and your USRP.

Installing in a custom directory
The generic instructions above install GNU Radio to /usr/local. It is however possible to install to a location of your choice. In order to do that you have to configure the build to use the custom prefix:

cmake -DCMAKE_INSTALL_PREFIX=/opt/gnuradio ../ ... This will configure GNU Radio to be installed to /opt/gnuradio rather than the default /usr/local

It is now necessary to add the custom installation directories to our environment settings, otherwise applications will not be able to find the headers, libraries, python scripts, etc. Open your .bashrc file (e.g. type &quot;gedit .bashrc&quot; in the terminal) and add to the end of the file:

export PATH=$PATH:/opt/gnuradio/bin export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/gnuradio/lib export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/opt/gnuradio/lib/pkgconfig export PYTHONPATH=$PYTHONPATH:/opt/gnuradio/lib/python2.6/site-packages The changes will take effect when you restart your session, e.g. log out and log in again.
 * 1) GNU Radio installation

= Building GNU Radio on Legacy Ubuntu =


 * This page describes how to build and install GNU Radio from source on releases of Ubuntu Linux that are no longer supported by Canonical (9.10 or earlier). We strongly recommend using a newer version of Ubuntu.

Installation Options
This page provides information and scripts to compile and install GNU Radio and its required background applications, libraries, and includes on Ubuntu Linux 6.10 (&quot;Edgy&quot;) or newer; they can probably be applied to some previous versions, though that hasn't been tested.

You might not be able to install the newest GNU Radio version unless you backport some of the depencies!

Pre-Requisites for Source Build
See those for newer Ubuntus.

Install Scripts
The following are scripts to take most users through a GNU Radio install on a typical Ubuntu install, with the hope that it provides enough guidance such that you can get GNU Radio up and running on your Ubuntu box.


 * This section is for Edgy or previous only (no changes are needed on Feisty or newer, except possibly to disable the CDROM entry):

Manually uncomment all repositories to include &quot;universe&quot; and &quot;multiverse&quot; either via direct editing

sudo /etc/apt/sources.list or via the provided GUI: System &gt; Administration &gt; Software Sources. Then enter the admin password for access. On the &quot;Ubuntu&quot; tab, make sure all of &quot;main restricted universe multiverse&quot; are checked and the rest unchecked (or deal with those are you deem correct for your setup). Click &quot;Close&quot;, then &quot;Reload&quot; to update the package list.

The uncommented lines of the file &quot;/etc/apt/sources.list&quot; should read something like (DIST is a string with your particular distribution: edgy, feisty, gusty, etc):

deb http://us.archive.ubuntu.com/ubuntu/ DIST main restricted universe multiverse deb http://us.archive.ubuntu.com/ubuntu/ DIST-updates main restricted universe multiverse deb http://security.ubuntu.com/ubuntu/ DIST-security main restricted universe multiverse Update the local dpkg cache:

sudo apt-get update Install required packages (some are likely already installed by Ubuntu by default; some are likely redundant with others; but these groups cover all of the required packages, except for in Edgy)


 * Karmic (9.10)

sudo apt-get -y install swig g++ automake autoconf libtool python-dev libfftw3-dev \ libcppunit-dev libboost1.38-dev libusb-dev fort77 sdcc sdcc-libraries \ libsdl1.2-dev python-wxgtk2.8 git-core guile-1.8-dev \ libqt4-dev python-numpy ccache python-opengl libgsl0-dev \ python-cheetah python-lxml doxygen qt4-dev-tools \ libqwt5-qt4-dev libqwtplot3d-qt4-dev pyqt4-dev-tools python-qwt5-qt4
 * Jaunty (9.04)

Package sdcc-nf needs to be installed (instead of sdcc)

sudo apt-get -y install swig g++ automake1.9 autoconf libtool python-dev fftw3-dev \ libcppunit-dev libboost1.35-dev sdcc-nf libusb-dev \ libsdl1.2-dev python-wxgtk2.8 git-core guile-1.8-dev \ libqt4-dev python-numpy ccache python-opengl libgsl0-dev \ python-cheetah python-lxml doxygen qt4-dev-tools \ libqwt5-qt4-dev libqwtplot3d-qt4-dev pyqt4-dev-tools python-qwt5-qt4 Note: If you are upgrading from an older install, you may have python-wxgtk2.6 installed.

Because python-wxgtk2.6 takes precedence over python-wxgtk2.8, it must be removed first: sudo apt-get remove python-wxgtk2.6


 * Intrepid (8.10)

Package sdcc-nf needs to be installed instead of sdcc

sudo apt-get -y install swig g++ automake1.9 autoconf libtool python-dev fftw3-dev \ libcppunit-dev libboost1.35-dev sdcc-nf libusb-dev \ libsdl1.2-dev python-wxgtk2.8 git-core guile-1.8-dev \ libqt4-dev python-numpy ccache python-opengl libgsl0-dev \ python-cheetah python-lxml doxygen qt4-dev-tools \ libqwt5-qt4-dev libqwtplot3d-qt4-dev pyqt4-dev-tools python-qwt5-qt4
 * Hardy (8.04): Boost should be installed as explained in README.building-boost file

sudo apt-get -y install swig g++ automake1.9 libtool python-dev fftw3-dev \ libcppunit-dev sdcc libusb-dev libasound2-dev libsdl1.2-dev \ python-wxgtk2.8 subversion guile-1.8-dev libqt4-dev python-numpy-ext \ ccache python-opengl libgsl0-dev python-cheetah python-lxml doxygen \ libqwt5-qt4-dev libqwtplot3d-qt4-dev qt4-dev-tools pyqt4-dev-tools
 * Gutsy (7.10): Boost should be installed as explained in README.building-boost file. GSL is required Also

sudo apt-get -y install g++ automake libtool python-dev fftw3-dev \ libcppunit-dev sdcc libusb-dev libasound2-dev \ libsdl1.2-dev python-wxgtk2.8 subversion guile-1.8-dev libgsl0-dev \ libqt3-mt-dev python-numpy-ext swig ccache
 * Feisty (7.04): Boost should be installed as explained in README.building-boost file. GSL is required Also

sudo apt-get -y install g++ automake1.9 libtool python-dev fftw3-dev \ libcppunit-dev sdcc libusb-dev libasound2-dev \ libsdl1.2-dev python-wxgtk2.8 subversion guile-1.6-dev\ libqt3-mt-dev python-numpy-ext swig ccache
 * Edgy (6.10): It is strongly recommended that you use one of the newer releases above

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-dev \ libqt3-mt-dev python-numpy-ext ccache Note that above line for Edgy installs python-wxgtk-2.6. While this is good enough for older gnuradio releases, it is too old for recent gnuradio svn snapshots. If you want to build a recent svn snapshot of gnuradio you need wxgtk version 2.8 or later.

You can install more recent wxgtk versions from the wxwidgets debian and ubuntu repository.

See Installing latest wxgtk-2.8 packages on debian or Ubuntu

Install optional packages, if desired; some might already be installed from the previous command:

sudo apt-get -y install gkrellm wx-common libwxgtk2.8-dev alsa-base autoconf xorg-dev g77 gawk bison openssh-server emacs cvs usbview octave For Edgy only: Get, Compile, and Install SWIG

wget http://prdownloads.sourceforge.net/swig/swig-1.3.33.tar.gz tar zxf swig-1.3.33.tar.gz cd swig-1.3.33 ./configure make sudo make install cd .. Optional: Get, Compile, Install QWT 5.0.0 (or newer):


 * NOTE: You should not need to set the environment variables &quot;QTDIR&quot; or &quot;QWT_CFLAGS&quot;, so leave them be (for now).

wget http://superb-east.dl.sourceforge.net/sourceforge/qwt/qwt-5.0.2.tar.bz2 tar jxf qwt-5.0.2.tar.bz2 cd qwt-5.0.2
 * Now edit qwtconfig.pri:

 Change the unix version of &quot;INSTALLBASE&quot; to &quot;/usr/local&quot; (was &quot;/usr/local/qwt-5.0.2&quot;);

 Change &quot;doc.path&quot; to &quot;$$INSTALLBASE/doc/qwt&quot; (was &quot;$$INSTALLBASE/doc&quot;);

 Save, exit.

The &quot;doc&quot; portion is in both HTML and man-style, but is all in /usr/local/doc/{html,man}. While this isn't the standard path, there doesn't seem to be an easy way to separate them and thus this is left as is. Then:

qmake make sudo make install cd ..

Install Boost
For Ubuntu 8.04 and older, download and install Boost 1.35 or later as follows (see README.building-boost file):

1) Download the latest version of boost from boost.sourceforge.net (boost_1_37_0.tar.bz2 was the latest when this was written but GNU Radio works with newer versions as well).

2) unpack it somewhere and cd into the resulting directory

$ cd boost_1_37_0 3) Pick a prefix to install it into. For example use /opt/boost_1_37_0

$ BOOST_PREFIX=/opt/boost_1_37_0 4) Configure

$ ./configure --prefix=$BOOST_PREFIX --with-libraries=thread,date_time,program_options 5) Compile the package

$ make 6) Install the package

$ sudo make install

$ cd ..

Installing GNU Radio
Download, bootstrap, configure, and compile GNU Radio package:


 * 1) Install GNU Radio from git

git clone --recursive http://git.gnuradio.org/git/gnuradio.git

cd gnuradio export LD_LIBRARY_PATH=$BOOST_PREFIX/lib    # As per the instructions for installing Boost

./bootstrap ./configure --with-boost=$BOOST_PREFIX  # As per the instructions for installing Boost make Optionally: Run the GNU Radio software self-check; does not require a USRP.

make check If any test or tests do not work, GNU Radio might still function properly, but it might be wise to look in the email archives for a fix or to write the email list. If writing to the email list, please include the OS type, OS version, and CPU type (e.g. via &quot;uname -a&quot;), anything special about the computer hardware, software versions (gcc, g++, swig, sdcc, etc) and how installed (standard or non-standard package, source).

Now install GNU Radio for general use (default is in to /usr/local ):

sudo make install Make sure you configure USRP support through udev (see top).

 NOTE: If installing on Feisty or newer, the computer probably needs to be rebooted in order for the GNU Radio software to interface correctly with the USRP hardware. This does not seem to be necessary on Edgy.

Update the rest of the system, after which you might need or want to reboot:

sudo apt-get -y upgrade Update the Linux distro, after which a reboot is required:

sudo apt-get -y dist-upgrade

Broken libtool on Debian and Ubuntu
Because Debian and Ubuntu apply a poorly implemented &quot;enhancement&quot; to the upstream version of libtool,

they break the ability to test code and libraries prior to installing them. We think that testing before

installation is a good idea. To work around their damage, be sure to include

$PREFIX/lib (and $PREFIX/lib64 on 64-bit machines) in /etc/ld.so.conf.

If you don't include $PREFIX/lib in /etc/ld.so.conf, you will see errors during the linking phase

of the build. There are several places it shows up. The first one is often during the build of

mblocks. It's not an mblock problem. It's a Debian/Ubuntu problem.

Do this to work around this feature

1) Make a copy from the current ld.so.conf file and save it in a temp folder:

cp /etc/ld.so.conf /tmp/ld.so.conf 2) Add /usr/local/lib path to it :

echo /usr/local/lib &gt;&gt; /tmp/ld.so.conf 3) If you installed Boost (version 1_37_0 for example) manually, then add its library path to the file:

echo /opt/boost_1_37_0/lib &gt;&gt; /tmp/ld.so.conf 4) Delete the original ld.so.conf file and put the modified file instead:

sudo mv /tmp/ld.so.conf /etc/ld.so.conf 5) Do ldconfig:

sudo ldconfig
