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

== Linux ==
 
Most distributions contain a package named <code>gnuradio</code> 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The development of GNU Radio is can be fast-paced, and binaries provided by your distribution may be outdated.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 it.
 
If the version shipped in your distribution is outdated please contact the corresponding maintainer to update it in the packaging system.

On other distributions, simply use the appropriate package management command to install the <code>gnuradio</code> package and 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.
= Other Installation Methods =
 
=== Ubuntu PPA Installation ===
For Ubuntu, the latest builds (both released and pulled from master branch) are maintained as PPAs on [https://launchpad.net/~gnuradio/+archive/ubuntu/gnuradio-master launchpad].  Be sure to uninstall gnuradio first.
 
To access the latest released version, add the gnuradio/gnuradio-releases ppa (removing other gnuradio ppas if already configured)
 
<pre>$ sudo add-apt-repository ppa:gnuradio/gnuradio-releases</pre>
 
To access the latest from the master branch, add the gnuradio/gnuradio-master ppa (removing other gnuradio ppas if already configured)
 
<pre>$ sudo add-apt-repository ppa:gnuradio/gnuradio-master</pre>
 
To access the 3.7 released version (legacy), add the gnuradio/gnuradio-releases-3.7 ppa (removing other gnuradio ppas if already configured)
 
<pre>$ sudo add-apt-repository ppa:gnuradio/gnuradio-releases-3.7</pre>
 
Then, update the apt sources, and install gnuradio
<pre>$ sudo apt-get update</pre>
<pre>$ sudo apt install gnuradio</pre>
 
==== 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:
 
<pre>$ cd /usr/share/gnuradio/modtool/templates/gr-newmod
$ sudo py3clean .</pre>
 
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:
<pre>$ sudo dnf copr enable gnuradio/gnuradio-releases </pre>
-- For the latest pull from git master:
<pre>$ sudo dnf copr enable gnuradio/gnuradio-master </pre>
 
2. Install GNU Radio
<pre>$ sudo dnf install gnuradio </pre>
 
== Windows ==
 
Binary installers are now available for 3.8.0.0, download them [http://www.gcndevelopment.com/gnuradio/downloads.htm here].<br />
If you need to install GNU Radio from source refer to the [[WindowsInstall|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 [[MacInstall|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 <b>FIRST</b> must clone and install UHD. See [[https://kb.ettus.com/Building_and_Installing_the_USRP_Open-Source_Toolchain_(UHD_and_GNU_Radio)_on_Linux UHD Installation Page]] for more info.
* To install on a Raspberry Pi, see [[InstallingGRFromSource on Raspberry Pi]].
 
=== For the GNU Radio Master Branch ===
 
Since Volk is no longer considered as a submodule of GNU Radio (GNU Radio commit #80c04479da962d048d41165081b026aafdaa0316 ),<br> you <b>MUST FIRST</b> 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 [[InstallingGR#Linux|this page for your specific Linux distro]] to find how to install dependencies.  For example, on Ubuntu 18 [[UbuntuInstall#Bionic Beaver (18.04) through Eoan Ermine (19.10)|use this command]].
 
==== Step 2: Installing Volk ====
 
* <code>cd</code>
* <code>git clone https://github.com/gnuradio/volk.git</code>
* <code>cd volk</code>
* <code>mkdir build</code>
* <code>cd build</code>
* <code>cmake -DCMAKE_BUILD_TYPE=Release -DPYTHON_EXECUTABLE=/usr/bin/python3 ../</code>
* <code>make</code>
* <code>make test</code>
* <code>sudo make install</code>
 
If you're running Linux, then always remember to do the following command after installing any library:
* <code>sudo ldconfig</code>
 
==== Step 3: Installing GNU Radio ====
* <code>cd</code>
* <code>git clone https://github.com/gnuradio/gnuradio.git</code>
* <code>cd gnuradio</code>
* <code>mkdir build</code>
* <code>cd build</code>
* <code>cmake -DCMAKE_BUILD_TYPE=Release -DPYTHON_EXECUTABLE=/usr/bin/python3 ../</code>
* <code>make</code>
 
<b>Note:</b> 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.
 
* <code>make test</code>
* <code>sudo make install</code>
 
Again, if you're running Linux, then always remember to do the following command after installing any library:
* <code>sudo ldconfig</code>
 
If you encounter "Cannot import gnuradio" error, then go to [[ModuleNotFoundError#B._Finding_the_Python_library|Finding the Python library]] to set your PYTHONPATH and LD_LIBRARY_PATH.<br><b>After setting these environment variables, you need to do</b> <code>sudo ldconfig</code> <b>again</b> for the Linux dynamic library loader to find the just-installed GNU Radio libraries.
 
=== 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.
 
* <code>cd</code>
* <code>git clone https://github.com/gnuradio/gnuradio.git</code>
* <code>cd gnuradio</code>
* <code>git clone https://github.com/gnuradio/volk.git</code>
 
<b>Note:</b> In the following command, change <code>maint-3.8</code> to some other branch or tag if you want to build a different version of GNU Radio; see [https://github.com/gnuradio/gnuradio/tags tags] for tagged releases including pre-releases ("rc"). For  [https://github.com/gnuradio/gnuradio/branches branches], it's generally wise to stick with "master" (the default after cloning), and, currently: <code>maint-3.7</code> or <code>maint-3.8</code>. Here we checkout the <code>maint-3.8</code> branch, which contains the latest 3.8 release plus any fixes or augmentations to it that will be in the next 3.8 release.
 
* <code>git checkout maint-3.8</code>
 
<b>Note:</b> In the following command, change <code>v2.2.1</code> to some other branch or tag if you want to build a different version of Volk; see [https://github.com/gnuradio/volk/tags tags] for tagged releases. You may skip the following <code>git checkout</code> command if you are not experiencing related bugs or build issues, but you may need to use an older release of Volk in order to build an older release of GNU Radio (including 3.7 releases).
 
* <code>cd volk</code>
* <code>git checkout v2.2.1</code>
* <code>cd ..</code>
 
* <code>mkdir build</code>
* <code>cd build</code>
 
<b>Note:</b> In the following command, you can use <code>-DCMAKE_INSTALL_PREFIX=XXX</code> to install GNU Radio into the PREFIX <code>XXX</code>; if not specified, then the PREFIX is <code>/usr/local</code>. See other CMake options in [[#Common_cmake_flags|Common cmake flags]].<br>
 
* <code>cmake -DCMAKE_BUILD_TYPE=Release -DPYTHON_EXECUTABLE=/usr/bin/python3 ../</code>
 
<b>Note:</b> In the following command, if your computer's CPU has multiple cores, you can use the argument <code>-j#</code> to speed compilation; <br> e.g., <code>make -j3</code> will use 3 threads in the build. Specify at least one less than the number of CPU cores so the system does not appear to 'freeze' during the build. If not specified, then a single thread is used for the build; this is not necessarily a bad thing, but it will take roughly 2 times as long to build as using 2 threads, and roughly 3 times as long to build as using 3 threads.<br>
 
* <code>make</code>
 
<b>Note:</b> 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.
 
* <code>make test</code>
* <code>sudo make install</code>
 
If you're running Linux, then always remember to do the following command after installing any library:
* <code>sudo ldconfig</code>
 
Go to [[ModuleNotFoundError#B._Finding_the_Python_library|Finding the Python library]] to set your PYTHONPATH and LD_LIBRARY_PATH.<br><b>After setting these environment variables, you need to do</b> <code>sudo ldconfig</code> <b>again</b> for the Linux dynamic library loader to find the just-installed GNU Radio libraries.


== Common cmake flags ==
== Platform-specific guides ==


* <code>-DENABLE_GR_XXX=ON</code> 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.
* [[LinuxInstall|Linux install guide]]
* <code>-DCMAKE_INSTALL_PREFIX=XXX</code> Install your stuff to XXX.
* [[WindowsInstall|Windows install guide]]
* <code>-DCMAKE_BUILD_TYPE=Debug</code> This causes gcc to add debug symbols to all binaries. Useful for debugging (otherwise, it decreases efficiency!)
* [[MacInstall|Mac OS X install guide]]
* <code>-DPYTHON_EXECUTABLE=/usr/bin/python{2,3}</code> 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.
<p>For a list of additional cmake flags, as well as minimum versions of dependencies, see [https://www.gnuradio.org/doc/doxygen/build_guide.html]</p>


= Using PyBOMBS =
== Cross-platform guides ==


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.
* [[CondaInstall|Conda install guide]]
* [https://github.com/gnuradio/pybombs#pybombs PyBOMBS] - Note: We are no longer including PyBOMBS as a recommended method of installing GNU Radio, unless you want to play around with old versions (e.g. GR 3.7, 3.8, and OOTs of matching version)


The PyBOMBS documentation is in the PyBOMBS [https://github.com/gnuradio/pybombs#pybombs README].
== VMs and Live Images ==
Over the years a number of Live Images and VMs have been created.  There are currently no official versions but here are some current options:
*[https://github.com/bastibl/instant-gnuradio Instant GNU Radio] A customizable, programmatically generated VM and live environment for GNU Radio.
*[[UbuntuVM]] An Ubuntu 20.04 virtual machine image with GNU Radio 3.8.2.0, Fosphor, GQRX, and several other useful pieces of software. (Created using Instant GNU Radio)

Other Installation Methods

Platform-specific guides

Cross-platform guides

  • Conda install guide
  • PyBOMBS - Note: We are no longer including PyBOMBS as a recommended method of installing GNU Radio, unless you want to play around with old versions (e.g. GR 3.7, 3.8, and OOTs of matching version)

VMs and Live Images

Over the years a number of Live Images and VMs have been created. There are currently no official versions but here are some current options:

  • Instant GNU Radio A customizable, programmatically generated VM and live environment for GNU Radio.
  • UbuntuVM An Ubuntu 20.04 virtual machine image with GNU Radio 3.8.2.0, Fosphor, GQRX, and several other useful pieces of software. (Created using Instant GNU Radio)

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).
