InstallingGR

From Binaries

The recommended way to install GNU Radio on most platforms is using already available binary packages (see Ubuntu PPA Installation). For some platforms there are no binaries provided by available package managers or the GNU Radio project. In these cases please contact the maintainer of the package manager or the GNU Radio project to find a sensible way to provide binaries for your platform.

In addition to using binaries, GNU Radio can be installed:

1. From source (for those who want full control)
2. Using PyBOMBS (for those who want it built from source and/or installed to a specific directory using a script)
3. Using conda (for those who want binaries installed to managed environments)

Linux

Most distributions contain a package named gnuradio or similar in their standard repositories. For most use cases it is enough to install this package and start developing.

The development of GNU Radio can be fast-paced, and binaries provided by your distribution may be outdated. Do check if the version you're installing is up to date! Sometimes old versions are not updated in the packaging systems. If you find a bug in a older GNU Radio version, please check if the bug still exists in the newer version of GNU Radio before filing a new issue.

If the version shipped in your distribution is outdated please contact the corresponding maintainer to update it in the packaging system.

Here are examples of how to install GNU Radio in various Linux distributions (click the link under "Distribution" for more installation details):

Distribution	Command
Debian/Ubuntu and derivates	$ apt install gnuradio
Fedora	$ dnf install gnuradio
RHEL/CentOS	$ yum install gnuradio
Archlinux	$ pacman -S gnuradio
Gentoo Linux	$ emerge net-wireless/gnuradio
Suse Linux

On other distributions, simply use the appropriate package management command to install the gnuradio package and then please add it to this list. If you need newer versions or have a different platform please contact the package maintainer of your distribution or raise your issue on the mailing list.

Ubuntu PPA Installation

For Ubuntu, the latest builds (both released and pulled from master branch) are maintained as PPAs on launchpad. Be sure to uninstall any previously installed versions of gnuradio first.

To access the latest from the master branch, add the gnuradio/gnuradio-master ppa (removing other gnuradio ppas if already configured)

$ sudo add-apt-repository ppa:gnuradio/gnuradio-master

To access the current released version (3.9), add the gnuradio/gnuradio-releases ppa (removing other gnuradio ppas if already configured)

$ sudo add-apt-repository ppa:gnuradio/gnuradio-releases

To access the 3.8 released version, add the gnuradio/gnuradio-releases-3.8 ppa (removing other gnuradio ppas if already configured)

$ sudo add-apt-repository ppa:gnuradio/gnuradio-releases-3.8

To access the 3.7 released version (legacy), add the gnuradio/gnuradio-releases-3.7 ppa (removing other gnuradio ppas if already configured)

$ sudo add-apt-repository ppa:gnuradio/gnuradio-releases-3.7

Then, update the apt sources, and install gnuradio

$ sudo apt-get update

$ sudo apt install gnuradio

Modtool on Ubuntu

NOTE: On released builds for Ubuntu 18 (bionic), there is an issue using gr_modtool after GNU Radio has been installed from the PPA. This is due to byte-compiled code that remains in the modtool templates after installation. To workaround this issue:

$ cd /usr/share/gnuradio/modtool/templates/gr-newmod
$ sudo py3clean .

This issue does not appear for Ubuntu 19 and later packages

Fedora COPR Installation

Packages are available for Fedora 29,30,31 hosted under COPR:

https://copr.fedorainfracloud.org/coprs/gnuradio/

1. Add the repository:

-- For the latest released version:

$ sudo dnf copr enable gnuradio/gnuradio-releases 

-- For the latest pull from git master:

$ sudo dnf copr enable gnuradio/gnuradio-master 

2. Install GNU Radio

$ sudo dnf install gnuradio 

Raspberry Pi

There is a pre-built 32 bit SDR flavored Raspberry Pi OS distro, PiSDR that includes GnuRadio and other SDR utilities.

Windows

Binary installers are now available for GNU Radio 3.7 and 3.8, download them here.
Conda packages are an alternative for installing binaries for GNU Radio 3.8+. See the conda install guide.
If you need to install GNU Radio from source refer to the Windows install guide.

Note: We do not officially support Windows. We do our best to provide installation instructions and work out build bugs on Windows when they are reported and patches received. As new versions of GNU Radio, its dependencies, and Windows itself come out, however, keeping all of them working together is beyond the scope of what the project currently supports. User updates to the above wiki installation instructions are very welcome.

Mac OS X

Refer to the Mac OS X install guide page.

From Source

Binary installation should be sufficient for most users, and certainly for anyone who is new to GNU Radio. However, if you have special requirements, want the latest version, or the binary packages are not working for you, you may want to install GNU Radio from source.

Notes

• By default GNU Radio will be installed in the /usr/local directory. See notes about -DCMAKE_INSTALL_PREFIX to install it elsewhere.
• Running and developing out-of-tree modules does not require GNU Radio to be installed from source.
• If you are using Ubuntu, see UbuntuInstall#Install_the_Pre-Requisites for installing dependencies / pre-requisites.
• If you want to use GNU Radio with a USRP, you FIRST must clone and install UHD. See [UHD Installation Page] for more info.
• To install on a Raspberry Pi, see InstallingGRFromSource on Raspberry Pi.
• To build from source from within a conda environment, see the conda install guide.

For the GNU Radio Master Branch

Since Volk is no longer considered as a submodule of GNU Radio (GNU Radio commit #80c04479da962d048d41165081b026aafdaa0316 ),
you MUST FIRST install Volk, and then install GNU Radio.

The basic idea is the same, but instead of building Volk along with GNU Radio, you need to clone and build it separately. For this example, we will start in the home directory. You can, of course, use any directory you wish and the results will be the same.

Step 1: Installing Dependencies

Refer to this page for your specific Linux distro to find how to install dependencies. For example, on Ubuntu 20.04 use this command.

Step 2: Installing Volk

• cd
• git clone --recursive https://github.com/gnuradio/volk.git
• cd volk
• mkdir build
• cd build
• cmake -DCMAKE_BUILD_TYPE=Release -DPYTHON_EXECUTABLE=/usr/bin/python3 ../
• make
• make test
• sudo make install

If you're running Linux, then always remember to do the following command after installing any library:

• sudo ldconfig

Step 3: Installing GNU Radio

• cd
• git clone https://github.com/gnuradio/gnuradio.git
• cd gnuradio

Note: If you want to build the maint-3.9 branch rather than the default master branch, enter: git checkout maint-3.9 and then

• mkdir build
• cd build

Note: In the following command, you can add -DCMAKE_INSTALL_PREFIX=XXX to install GNU Radio into the PREFIX XXX; if not specified, then the PREFIX is /usr/local. See other CMake options in Common cmake flags.

• cmake -DCMAKE_BUILD_TYPE=Release -DPYTHON_EXECUTABLE=/usr/bin/python3 ../
• make -j3 (e.g. if you want to use 3 CPU cores during the build. To use 8 do -j8, to use 1 leave out the -j flag.)

Note: In the following command, it is very possible that not all tests pass. Generally any error is a sign of a missing dependency such as the Python interface to ZMQ or NumPy or SciPy, none of which are required for building GNU Radio but are required for testing.

• make test
• sudo make install

If you're running Linux, then always remember to do the following command after installing any library:

• sudo ldconfig

If you encounter "Cannot import gnuradio" error, then go to Finding the Python library to set your PYTHONPATH and LD_LIBRARY_PATH.
After setting these environment variables, you need to do sudo ldconfig again for the Linux dynamic library loader to find the just-installed GNU Radio libraries.
If you have installed in a custom path with -DCMAKE_INSTALL_PREFIX=XXX, you will need to add that path to $PATH in order to find gnuradio-companion.

For GNU Radio 3.8 or Earlier

For this example, we will start in the home directory; you can, of course, use any directory you wish and the results will be the same.

• cd
• git clone https://github.com/gnuradio/gnuradio.git
• cd gnuradio

Note: In the following command, change maint-3.8 to some other branch or tag if you want to build a different version of GNU Radio; see tags for tagged releases including pre-releases ("rc"). For branches, it's generally wise to stick with "master" (the default after cloning), and, currently: maint-3.7 or maint-3.8. Here we checkout the maint-3.8 branch, which contains the latest 3.8 release plus any fixes or augmentations to it that will be in the next 3.8 release.

• git checkout maint-3.8
• git submodule update --init --recursive
• mkdir build
• cd build

Note: In the following command, you can add -DCMAKE_INSTALL_PREFIX=XXX to install GNU Radio into the PREFIX XXX; if not specified, then the PREFIX is /usr/local. See other CMake options in Common cmake flags.

• cmake -DCMAKE_BUILD_TYPE=Release -DPYTHON_EXECUTABLE=/usr/bin/python3 ../
• make -j3 (e.g. if you want to use 3 CPU cores during the build. To use 8 do -j8, to use 1 leave out the -j flag.)
• sudo make install

If you're running Linux, then always remember to do the following command after installing any library:

• sudo ldconfig

Go to Finding the Python library to set your PYTHONPATH and LD_LIBRARY_PATH.
After setting these environment variables, you need to do sudo ldconfig again for the Linux dynamic library loader to find the just-installed GNU Radio libraries.
If you have installed in a custom path with -DCMAKE_INSTALL_PREFIX=XXX, you will need to add that path to $PATH in order to find gnuradio-companion.

For Ubuntu 18.04

An easy way to install GNU Radio 3.8 on many Ubuntu systems is to use the following commands (note that this skips the setup for UHD hardware):

• sudo apt install git cmake g++ libboost-all-dev libgmp-dev swig python3-numpy python3-mako python3-sphinx python3-lxml doxygen libfftw3-dev libsdl1.2-dev libgsl-dev libqwt-qt5-dev libqt5opengl5-dev python3-pyqt5 liblog4cpp5-dev libzmq3-dev python3-yaml python3-click python3-click-plugins python3-zmq python3-scipy python3-pip python3-gi-cairo
• pip3 install git+https://github.com/pyqtgraph/pyqtgraph@develop
• pip3 install numpy scipy
• echo 'export PYTHONPATH=/usr/local/lib/python3/dist-packages:usr/local/lib/python2.7/site-packages:$PYTHONPATH' >> ~/.bashrc
• echo 'export LD_LIBRARY_PATH=/user/local/lib:$LD_LIBRARY_PATH' >> ~/.bashrc
• echo 'export PYTHONPATH=/usr/local/lib/python3/dist-packages:usr/local/lib/python2.7/site-packages:$PYTHONPATH' >> ~/.profile
• echo 'export LD_LIBRARY_PATH=/user/local/lib:$LD_LIBRARY_PATH' >> ~/.profile
• cd ~/
• git clone --recursive https://github.com/gnuradio/gnuradio
• cd gnuradio
• git checkout maint-3.8
• mkdir build
• cd build
• git pull --recurse-submodules=on
• git submodule update --init
• cmake -DENABLE_GR_UHD=OFF ..
• make -j $(nproc --all)
• sudo make install
• sudo ldconfig

Once this is done, reboot your computer and GNU Radio should be all set for you.

Common cmake flags

• -DENABLE_GR_XXX=ON This enables (or disables for =OFF) the GNU Radio component named XXX. You might not need all of them, and this way, you can compile quicker.
• -DCMAKE_INSTALL_PREFIX=XXX Install your stuff to XXX.
• -DCMAKE_BUILD_TYPE=Debug This causes gcc to add debug symbols to all binaries. Useful for debugging (otherwise, it decreases efficiency!)
• -DPYTHON_EXECUTABLE=/usr/bin/python{2,3} This selects the Python version and executable to be used during build time and will determine which Python libraries will be used for building the Python bindings.

For a list of additional cmake flags, as well as minimum versions of dependencies, see [1]

Using PyBOMBS

PyBOMBS is good at building GNU Radio, UHD, and various Out of Tree (OOT) modules from source and then installing into a specified user directory rather than in the system files. PyBOMBS detects the user's Operating System and loads all of the prerequisites in the first stage of the build.

The PyBOMBS documentation is in the PyBOMBS README.

OK, it's installed, what now?

If the installation worked without any trouble, you're ready to use GNU Radio! If you have no idea how to do that, the best place to start is with the Tutorials.

Optionally, you may run volk_profile on your terminal to help libvolk to determine the optimal kernels (may speed up GNU Radio).
