This page describes several ways to build and install GNSS-SDR.
Installing everything through software package managers
GNU/Linux distributions based on Debian
Starting from Debian 9 and Ubuntu 16.04, you can install GNSS-SDR just by doing:
$ sudo apt-get install gnss-sdr
However, even on very recent distributions, the latest packaged GNSS-SDR version is often at least months behind the latest developments, and the same applies to its dependencies. In order to get access to the most recent features and bug fixes, you might want to build the software from the source code.
The good part: This is the easiest and fastest way to get GNSS-SDR installed in your system. Just a single line in your terminal will do all the work for you.
The downside: GNSS-SDR package updates need to undergo an acceptance process before they are included in the different distributions, so it might not be the ultimate version of the source code. The same applies for the dependency libraries.
macOS / Mac OS X using Macports
If you are using macOS 10.14 Mojave (or Mac OS X 10.9 and above), and the Macports package manager, GNSS-SDR can be installed by typing in a Terminal:
$ sudo port install gnss-sdr
This will install the latest stable release of GNSS-SDR.
You have more options here!
Instead of installing the latest stable release, you can install the code found on the
master branch, which might contain some bug fixes with respect to the latest stable release:
$ sudo port install gnss-sdr-devel
or the context of the
next branch, which might contain fixes and new features with respect to the latest stable release:
$ sudo port install gnss-sdr-next
If everything went fine, you can directly jump into how to get your first position fix. Or maybe you might prefer other options, such as using Homebrew instead of Macports as a software package manager, or to build the source code manually. Fore more details of GNSS-SDR on macOS, please check the README.md file.
Building from source
Is it better to compile from source or to install from a package? Here we provide some guidelines. The rule of thumb is: Always consider installing from standard packages of your Operating System first; only compile from sources if you know exactly why you need to do that.
GNSS-SDR and its software dependencies can all be installed either by downloading their source code, building and installing them in your system, or by installing the corresponding software package. Under GNU/Linux, the package manager may vary according to the distribution you are using (
.deb for Debian-based distros, such as Ubuntu, Linaro and Raspbian;
.rpm for Fedora / SUSE / Mandriva; etc.). In Mac OS X, most popular open source package managers are Macports and Homebrew. In all cases, a possible option for a quick jump into GNSS-SDR is to install all the dependencies from packages, and then building GNSS-SDR from the source code.
But maybe this approach does not fit your needs. Maybe you already have some dependency already built from source and want to use it, or your setup requires some specific flag somewhere. This is a building-time vs. fine-tuning trade-off. In order to take the adequate approach, just remember this basic rule:
Software packages require that all its dependencies must be also installed from packages.
and take into account the following considerations:
The good part: The advantage of compiling from source is that you can compile packages with certain flags/options which may be missing or disabled in standard packages. Also, it makes it easy to have multiple versions of the same program installed. Also, you can choose an exact version of a package which may be already removed from, or not yet present in, your OS repositories.
The downside: The disadvantage of compiling from source is that the usual
cmake .. && make && sudo make install procedure keeps your package manager completely unaware of the changes you are making, so you are not going to get any automatic updates for the manually-compiled software; and it is possible that package manager will later override/break your package if you are not careful to install it in a separate location.
Some highly automated tools that can do some of the work for you are described below.
Install all dependencies using packages
If you are using Debian 8, Ubuntu 14.10 or above, this can be done by copying and pasting the following line in a terminal:
$ sudo apt-get install build-essential cmake git libboost-dev \ libboost-date-time-dev libboost-system-dev libboost-filesystem-dev \ libboost-thread-dev libboost-chrono-dev libboost-serialization-dev \ libboost-program-options-dev libboost-test-dev liblog4cpp5-dev \ libuhd-dev gnuradio-dev gr-osmosdr libblas-dev liblapack-dev \ libarmadillo-dev libgflags-dev libgoogle-glog-dev libhdf5-dev \ libgnutls-openssl-dev libmatio-dev python-mako python-six \ libpugixml-dev libpcap-dev libprotobuf-dev protobuf-compiler \ libgtest-dev googletest
Note for Ubuntu 14.04 LTS users:
you will need to build from source and install GNU Radio manually, as explained below, since GNSS-SDR requires gnuradio-dev >= 3.7.3, and Ubuntu 14.04 came with 3.7.2. Install all the packages above BUT EXCEPT
gr-osmosdr (and remove them if they are already installed in your machine), and install those dependencies using PyBOMBS, as explained below.
Once you have installed these packages, you can jump directly to clone, build and install GNSS-SDR.
Install dependencies using PyBOMBS
This option is adequate if you are interested in development, in working with the most recent versions of software dependencies, want more fine-tuning on the installed versions, or simply in building everything from the scratch just for the fun of it. In such cases, we recommend to use PyBOMBS (Python Build Overlay Managed Bundle System), GNU Radio’s meta-package manager tool that installs software from source, or whatever the local package manager is, that automatically does all the work for you. Please take a look at the configuration options and general PyBOMBS usage. Here we provide a quick step-by-step tutorial.
First of all, install some basic packages:
$ sudo apt-get install git python-pip
Download, build and install PyBOMBS:
$ sudo pip install git+https://github.com/gnuradio/pybombs.git
Apply a configuration:
$ pybombs auto-config
Add list of default recipes (i.e., instructions on how to install software dependencies):
$ pybombs recipes add-defaults
Download, build and install GNU Radio, related drivers and some other extra modules into the directory
/path/to/prefix (replace this path by your preferred one, for instance
$ pybombs prefix init /path/to/prefix -a myprefix -R gnuradio-default
This will perform a local installation of the dependencies under
/path/to/prefix, so they will not be visible when opening a new terminal. In order to make them available, you will need to set up the adequate environment variables by sourcing the
$ cd /path/to/prefix $ . ./setup_env.sh
Now you are ready to use GNU Radio and to jump into building GNSS-SDR after installing a few other dependencies. Actually, those are steps that PyBOMBS can do for you as well:
$ pybombs install gnss-sdr
By default, PyBOMBS installs the ‘next’ branch of GNSS-SDR development, which is the most recent version of the source code. This behaviour can be modified by altering the corresponding recipe at
In case you do not want to use PyBOMBS and prefer to build and install GNSS-SDR step by step (i.e., cloning the repository and doing the usual
cmake .. && make && sudo make install dance, as explained below), there are still some missing dependencies (i.e., Armadillo, GFlags, Glog, GnuTLS and Protocol Buffers) that can be installed either by using PyBOMBS:
$ pybombs install armadillo gflags glog gnutls protobuf
or manually, just downloading, building and installing them. More details are available in the README.md file.
Clone, build and install GNSS-SDR
Once all the dependencies are installed in your system, you are ready to clone the repository, build the source code and install the software in your system:
$ git clone https://github.com/gnss-sdr/gnss-sdr $ cd gnss-sdr/build $ git checkout next $ cmake .. $ make $ sudo make install
git checkout next is optional, and sets the source tree pointing to the
next branch, which is the most recent development snapshot. If this step is omitted it takes the
master branch by default, which contains the latest stable release, and maybe some bug fixes.
In addition, CMake accepts a number of configuration options for your building process. For instance, if you want to compile your source in “Debug” mode instead of the default “Release”, you can type:
$ cmake -DCMAKE_BUILD_TYPE=Debug ..
and then CMake will add the debug flags appropriate for your compiler. There are more options that can be of your interest, such as the addition of extra drivers for RF front-ends not included by default, implementations of signal processing blocks that take advantage of your GPU, addition of experimental features, building of optional QA code, and so on. Check out the available building configuration options documentation for more details.
If everything went fine in the building process, now you can jump into how to get your first position fix.
Ninja is a small build system with a focus on speed, that can be seen as a replacement for
make. If the parameter
-GNinja is passed to CMake, it generates a
build.ninja file (instead of a
Makefile) that is used by the Ninja build system to compile and link the source code. Thus, after cloning the repository, the build workflow is:
$ cd gnss-sdr/build $ git checkout next $ cmake -GNinja .. $ ninja $ sudo ninja install
In general, the compilation time when using Ninja is comparable to that when using Make for a full build, although its performance is quite platform dependent. Ninja is specially targeted to improve performance in large projects and for incremental builds, so it seems to be a good replacement for Make especially for developers who need to often recompile the source code. In Debian-based GNU/Linux distributions, it can be installed by doing:
$ sudo apt-get install ninja-build
On macOS, Ninja can be installed using Macports:
$ sudo port install ninja
$ brew install ninja
More information about Ninja usage can be found in the Ninja Manual.
Clang is a compiler front end for C, C++ and other programming languages. It uses LLVM as its back end, and it is designed to be able to replace the full GNU Compiler Collection (GCC). Under macOS, this compiler is used by default. In GNU/Linux, it can be used to build GNSS-SDR in replacement of GCC.
In Debian/Ubuntu-based distributions, Clang can be installed by doing:
$ sudo apt-get install clang
Other packages specifying the Clang version, such as
clang-4.0 could exist for your distribution, check its documentation. Once installed, its use can be configured by passing the following parameters to CMake:
$ cmake -DCMAKE_CXX_COMPILER=/usr/bin/clang++-3.8 -DCMAKE_C_COMPILER=/usr/bin/clang-3.8 ..
of course replacing
3.8 by the actual version installed in your machine.
If you have the Ninja build system installed, you can build GNSS-SDR replacing GCC and
make by Clang and Ninja:
$ cmake -DCMAKE_CXX_COMPILER=/usr/bin/clang++-3.8 -DCMAKE_C_COMPILER=/usr/bin/clang-3.8 -GNinja ..
Snaps are universal Linux packages aimed to work on any distribution or device, from IoT devices to servers, desktops to mobile devices. Snaps are self-contained packages that bundle the application and all the libraries and runtimes it needs, and can be updated and reverted without affecting the rest of the system. Snaps are confined from the OS and other apps through security mechanisms, but can exchange content and functions with other snaps.

Docker is an open source tool designed to make it easier to create, deploy, and run applications by using containers. Docker containers wrap a piece of software in a complete filesystem that contains everything needed to run: code, runtime, system tools and system libraries, and ship it all out as one package. This guarantees that the software will always run the same, regardless of any customized settings that the executing machine might have that could differ from the machine used for writing and testing the code. Using containers is another way of packing applications, in a much lighter weight and with a much faster delivery model than using Virtual Machines.
Releases of Docker images with GNSS-SDR already installed are available from the Docker Hub.
