Building rtl_433

rtl_433 currently supports these input types:

Building rtl_433 with RTL-SDR or SoapySDR support is optional but using RTL-SDR is highly recommended. The libraries and header files for RTL-SDR and/or SoapySDR should be installed beforehand.

Nightly builds

Some distributions offer nightly builds.


openSUSE users of at least Leap 42.3 or Tumbleweed can add the repository with daily builds:

$ sudo zypper addrepo -f obs://home:mnhauke:rtl_433:nightly/rtl_433
$ sudo zypper install rtl_433

The usual update mechanism will now keep the rtl_433 version current.


Fedora users (31, 32 and Rawhide) can add the following copr repository to get nightly builds:

$ sudo dnf copr enable tvass/rtl_433
$ sudo dnf install rtl_433

The usual update mechanism will now keep the rtl_433 version current.

Linux / Mac OS X

Depending on your system, you may need to install the following libraries.


  • If you require TLS connections, install libssl-dev.
sudo apt-get install libtool libusb-1.0-0-dev librtlsdr-dev rtl-sdr build-essential cmake pkg-config

Centos/Fedora/RHEL with EPEL repo using cmake:

  • If dnf doesn't exist, use yum.
  • If you require TLS connections, install openssl-devel.
sudo dnf install libtool libusbx-devel rtl-sdr-devel rtl-sdr cmake

Mac OS X with MacPorts:

  • If you require TLS connections, install openssl from either MacPorts or Homebrew.
sudo port install rtl-sdr cmake

Mac OS X with Homebrew:

brew install rtl-sdr cmake pkg-config


Get the rtl_433 git repository if needed:

git clone

Installation using CMake:

cd rtl_433/
mkdir build
cd build
cmake ..
make install

Use CMake with -DENABLE_SOAPYSDR=ON (default: AUTO) to require SoapySDR (e.g. with Debian needs the package libsoapysdr-dev), use -DENABLE_RTLSDR=OFF (default: ON) to disable RTL-SDR if needed. E.g. use:



If you experience trouble with SoapySDR when compiling or running: you likely mixed version 0.7 and version 0.8 headers and libs. Purge all SoapySDR packages and source installation from /usr/local. Then install only from packages (version 0.7) or only from source (version 0.8).


Visual Studio 2017

You need PothosSDRopen in new window installed to get RTL-SDR and SoapySDR libraries. Any recent version should work, e.g. 2021.07.25-vc16open in new window.

When installing PothosSDR choose "Add PothosSDR to the system PATH for the current user".

For TLS support (mqtts and influxs) you need OpenSSL installed. E.g. install Chocolateyopen in new window then open a Command Prompt and

choco install openssl

Clone the project, e.g. open Visual Studio, change to "Team Explorer" > "Projects" > "Manage Connections" > "Clone" and enter

If you want to change options, in the menu select "CMake" > "Change CMake Settings" > "rtl433", select e.g. "x64-Release", change e.g.

"buildRoot": "${workspaceRoot}\\build",
"installRoot": "${workspaceRoot}\\install",

To start a build use in the menu e.g. "CMake" > "Build all"

Or build at the Command Prompt without opening Visual Studio. Clone rtl_433 sources, then

cd rtl_433
mkdir build
cd build
cmake -G "Visual Studio 15 2017 Win64" ..
cmake --build .


You'll probably want librtlsdr and libusb.

libusb has prebuilt binaries for windows, librtlsdr needs to be built (or extracted from the PothosSDR installer)


taken and adapted from here:

  • install MinGW-w64open in new window and CMakeopen in new window
    • it's easiest if you select the option to include CMake in your path, otherwise you'll need to do this manually
  • download the libusb binaries from or from
    • take the latest release and then download the .7z file, the other file contains the sources (or 'windows binaries' on the .info website)
  • extract the archive and open the extracted folder
  • copy the contents of the include folder to <mingw_installation_folder>/include
  • copy the mingw64/dll/libusb-1.0.dll.a file to `<mingw_installation_folder>/lib
  • copy the mingw64/dll/libusb-1.0.dll file to <mingw_installation_folder>/bin
  • download the source code of librtlsdr
  • go into the librtlsdr folder
  • open CMakeLists.txt with an editor that knows unix line endings
  • go to # Find build dependencies (around line 65) and comment/remove the line with find_package(Threads)
  • add the following lines instead:
  • go into the cmake/modules folder and open FindLibUSB.cmake with a text editor
  • find the lines with the following text in them
  • add some extra lines to point to the MinGW include folder where you extracted libusb-1.0, making it look like this
    • take note of the "" around the folder names, these are needed when there are spaces in the folder name
    • you'll need to find out the exact paths for your system
"C:/Program Files/mingw-w64/x86_64-8.1.0-posix-seh-rt_v6-rev0/mingw64/include"
"C:/Program Files/mingw-w64/x86_64-8.1.0-posix-seh-rt_v6-rev0/mingw64/include/libusb-1.0"
  • open a MinGW terminal in the librtlsdr folder
  • create build folder and go into it: mkdir build && cd build
  • generate makefiles for MinGW: cmake -G "MinGW Makefiles" ..
  • build the librtlsdr library: mingw32-make


  • clone the rtl_433 repository and cd into it
  • create a build folder and go into it: mkdir build && cd build
  • run cmake -G "MinGW Makefiles" .. in the build directory
  • run cmake-gui (this is easiest)
  • set the source (the rtl_433 source code directory) and the build directory (one might create a build directory in the source directory)
  • click configure
  • select the grouped and advanced tickboxes
  • go into the librtlsdr config group
  • point the LIBRTLSDR_INCLUDE_DIRS to the include folder of the librtlsdr source
  • point the LIBRTLSDR_LIBRARIES to the librtlsdr.dll.a file in the <librtlsdr_source>/build/src folder
    • that's the one you've built earlier
  • start a MinGW terminal and run mingw32-make to build
    • when something in the tests folder doesn't build, you can disable it by commenting out add_subdirectory(tests) in the CMakeLists.txt file in the source folder of rtl_433
  • rtl_433.exe should be built now
  • you need to place it in the same folder as librtlsdr.dll and libusb-1.0.dll (you should have seen both of them by now)
  • good luck!
