Our own flavor of DDRace, a Teeworlds mod. See the website for more information.

Development discussions happen on #ddnet on Quakenet (Webchat) or on Discord in the developer channel.

You can get binary releases on the DDNet website, find it on Steam or install from repository.


To clone this repository with full history and external libraries (~350 MB):

git clone --recursive

To clone this repository with full history when you have the necessary libraries on your system already (~220 MB):

git clone

To clone this repository with history since we moved the libraries to (~40 MB):

git clone --shallow-exclude=included-libs

To clone the libraries if you have previously cloned DDNet without them:

git submodule update --init --recursive

Dependencies on Linux

You can install the required libraries on your system,

touch CMakeLists.txt
and CMake will use the system-wide libraries by default. You can install all required dependencies and CMake on Debian or Ubuntu like this:
sudo apt install build-essential cmake git libcurl4-openssl-dev libssl-dev libfreetype6-dev libglew-dev libnotify-dev libogg-dev libopus-dev libopusfile-dev libpnglite-dev libsdl2-dev libsqlite3-dev libwavpack-dev python google-mock

Or on Arch Linux like this:

sudo pacman -S --needed base-devel cmake curl freetype2 git glew libnotify opusfile python sdl2 sqlite wavpack gmock

There is an AUR package for pnglite. For instructions on installing it, see AUR packages installation instructions on ArchWiki.

If you don't want to use the system libraries, you can pass the

parameter to cmake.

Building on Linux and macOS

To compile DDNet yourself, execute the following commands in the source root:

mkdir build
cd build
cmake ..
make -j$(nproc)

Pass the number of threads for compilation to

make -j
in this case returns the number of processing units. DDNet requires additional libraries, that are bundled for the most common platforms (Windows, Mac, Linux, all x86 and x86_64). The bundled libraries are now in the ddnet-libs submodule.

The following is a non-exhaustive list of build arguments that can be passed to the

command-line tool in order to enable or disable options in build time:
  • -DCMAKEBUILDTYPE=[Release|Debug|RelWithDebInfo|MinSizeRel]
    An optional CMake variable for setting the build type. If not set, defaults to "Release" if

    is not used, and "Debug" if
    is used. See
    in CMake Documentation for more information.
    Whether to prefer bundled libraries over system libraries. Setting to ON will make DDNet use third party libraries available in the

    folder, which is the git-submodule target of the ddnet-libs repository mentioned above -- Useful if you do not have those libraries installed and want to avoid building them. If set to OFF, will only use bundled libraries when system libraries are not found. Default value is OFF.
    Whether to enable WebSocket support for server. Setting to ON requires the

    library installed. Default value is OFF.
    Whether to enable MySQL/MariaDB support for server. Requires at least MySQL 8.0 or MariaDB 10.2. Setting to ON requires the

    libraries installed, which are also provided as bundled libraries for the common platforms. Default value is OFF.

Note that the bundled MySQL libraries might not work properly on your system. If you run into connection problems with the MySQL server, for example that it connects as root while you chose another user, make sure to install your system libraries for the MySQL client and C++ connector. Make sure that the CMake configuration summary says that it found MySQL libs that were not bundled (no "using bundled libs").

    Whether to enable the autoupdater. Packagers may want to disable this for their packages. Default value is ON for Windows and Linux.

    Whether to enable client compilation. If set to OFF, DDNet will not depend on Curl, Freetype, Ogg, Opus, Opusfile, and SDL2. Default value is ON.

    Whether to add video recording support using FFmpeg to the client. You can use command

    to start and stop conversion from demo to mp4. This feature is currently experimental and not enabled by default.

Dependencies needed on debian:

libx264-dev libavfilter-dev libavdevice-dev libavformat-dev libavcodec-extra libavutil-dev
    Whether to download and compile GTest. Useful if GTest is not installed and, for Linux users, there is no suitable package providing it. Default value is OFF.

  • -DDEV=[ON|OFF]
    Whether to optimize for development, speeding up the compilation process a little. If enabled, don't generate stuff necessary for packaging. Setting to ON will set CMAKE_BUILD_TYPE to Debug by default. Default value is OFF.

    Whether to enable UPnP support for the server. You need to install

    on Debian,
    on Arch Linux.
  • -GNinja
    Use the Ninja build system instead of Make. This automatically parallizes the build and is generally faster. Compile with

    instead of
    . Install Ninja with
    sudo apt install ninja-build
    on Debian,
    sudo pacman -S --needed ninja
    on Arch Linux.

Running tests (Debian/Ubuntu)

In order to run the tests, you need to install the following library


This library isn't compiled, so you have to do it: ```bash sudo apt install libgtest-dev cd /usr/src/gtest sudo cmake CMakeLists.txt sudo make -j8

copy or symlink libgtest.a and libgtest_main.a to your /usr/lib folder

sudo cp *.a /usr/lib ```

To run the tests you must target

with make:
make run_tests

Using AddressSanitizer + UndefinedBehaviourSanitizer or Valgrind's Memcheck

ASan+UBSan and Memcheck are useful to find code problems more easily. Please use them to test your changes if you can.

For ASan+UBSan compile with:

CC=clang CXX=clang++ CXXFLAGS="-fsanitize=address,undefined -fsanitize-recover=address,undefined -fno-omit-frame-pointer" CFLAGS="-fsanitize=address,undefined -fsanitize-recover=address,undefined -fno-omit-frame-pointer" cmake -DCMAKE_BUILD_TYPE=Debug .
and run with:
UBSAN_OPTIONS=log_path=./SAN:print_stacktrace=1:halt_on_errors=0 ASAN_OPTIONS=log_path=./SAN:print_stacktrace=1:check_initialization_order=1:detect_leaks=1:halt_on_errors=0 ./DDNet

Check the SAN.* files afterwards. This finds more problems than memcheck, runs faster, but requires a modern GCC/Clang compiler.

For valgrind's memcheck compile a normal Debug build and run with:

valgrind --tool=memcheck ./DDNet
Expect a large slow down.

Building on Windows with Visual Studio

Download and install some version of Microsoft Visual Studio (as of writing, MSVS Community 2017) with C++ support, install Python 3 for all users and install CMake.

Start CMake and select the source code folder (where DDNet resides, the directory with

). Additionally select a build folder, e.g. create a build subdirectory in the source code directory. Click "Configure" and select the Visual Studio generator (it should be pre-selected, so pressing "Finish" will suffice). After configuration finishes and the "Generate" reactivates, click it. When that finishes, click "Open Project". Visual Studio should open. You can compile the DDNet client by right-clicking the DDNet project (not the solution) and select "Select as StartUp project". Now you should be able to compile DDNet by clicking the green, triangular "Run" button.

Cross-compiling on Linux to Windows x86/x86_64

Install MinGW cross-compilers of the form

(32 bit) or
(64 bit). This is probably the hard part. ;)

Then add

to the initial CMake command line.

Cross-compiling on Linux to macOS

Install osxcross, then add

to the initial CMake command line.


from libdmg-hfsplus and
from diskdev_cmds to unlock the
target that outputs a macOS disk image.
