This page describes how to install the latest development version of the code. This may be unstable and is intended for those that want to actively follow or contribute to the software development. To install the latest alpha release, Download the Latest Alpha instead.

The development version of the game is aimed at software developers (not regular players). As such, these instructions assume a higher level of technical proficiency. If you encounter difficulties, please consult the forum.

System requirements

You'll need:

  • An adequately high-spec computer:
    • At least 30 GB of free disk space
    • At least 1 GB of RAM for compiling, more if compiling multiple jobs in parallel (using -j)
    • 32 or 64-bit x86-compatible CPU, or an ARMv5+ processor
    • Modern graphics hardware is also recommended, though the game can run (slowly) on fairly old devices (GeForce 4, Intel 945GM, etc)
  • One of the following operating systems:
  • Up-to-date system software (Windows service packs, graphics driver updates, etc)
  • Some technical proficiency. We try to make the build process as smooth and painless as possible, but it's designed to be followed by programmers - if you just want to play the game, wait for a pre-packaged installer instead.


The development environment for 0 A.D. is comprised of three layers. Each goes on top of the previous:

  1. Libraries.
  2. Workspaces.
  3. Source code.

Libraries are external dependencies (such as SpiderMonkey). For Windows and Linux, the script to create or update the Workspaces also handles installation and updating of libraries. For macOS, the libraries/osx/ script should be used instead.

Workspaces contain the integrations for code editors (such as Visual Studio, Xcode, etc.) as well as the Makefile for the main source code. The workspaces are auto-generated by the update-workspaces script from the buids/workspaces/ directory. Once ready, the integrations are ready for use, such as build/workspaces/gcc/Makefile (for Linux and macOS) and build\workspaces\vs2017 (for Windows).

Finally, the source code is build by the workspace. For example, by running make in build/workspaces/gcc.


The main supported versions are:

  • Windows 11
  • Windows 10
  • Windows 8.1
  • Windows 8
  • Windows 7

If you want to develop, the only supported IDE is:

Important notes:

  • We have dropped support for older versions of Visual Studio when moving to C++14, see #5862.
  • XP and Vista are no longer supported - SpiderMonkey 78 has dropped support for both. It is plausible that some fancy patching would work, but we haven't had the material means to try it.
  • Only 32-bit builds are supported, though they can be compiled and run on 64-bit Windows.

Getting the code

See Getting the Code.

Setting up the build environment

The game must be compiled with Microsoft Visual C++. You can get the free 2017 Community edition here: Visual Studio older downloads. You can also install Visual Studio 2019 (or 2022) and choose to install the 2017 compiler (version 15.0).

The Visual Studio project/solution files are automatically generated from the source files:

Build configuration

Make sure to select the "Release" configuration to build an optimized, more playable version of the game (the target will be pyrogenesis.exe). The "Debug" configuration can be more useful for debugging but has significantly reduced performance (the target will be pyrogenesis_dbg.exe). Both "Release" and "Debug" builds include debug symbols, see Debugging and Debugging on Windows for more details on debugging.

Now you should be able to build the code from within Visual Studio, using "Build Solution" (F5 in VS 2017 and Ctrl+B in VS 2019). 

Building Atlas

If you also wish to test the Atlas Scenario Editor or Actor Editor tools, you will need to download and build the wxWidgets library separately (version 3.0 and above; see ps\libraries\win32\wxwidgets\README.txt for details), then supply the --atlas option when running update-workspaces.bat. Atlas projects will now be included when you open pyrogenesis.sln in Visual C++.

Note: You might run into a few errors while building Atlas. As an easy fix, after update-workspaces.bat, just rebuild without the --atlas parameter and then copy atlasUI.dll into the binaries/system folder [see forum post]


Rightclick on "pyrogenesis" in the solution explorer panel on the right hand side and select "Set as StartUp Project". Run the game with F5 inside Visual Studio. You can close the game with SHIFT + F5 from inside vs studio if it becomes unresponsive. If you want to run it outside the debugger, run binaries\system\pyrogenesis_dbg.exe.

To run the automated tests, run the "test" project. (Right click on "test" and "set as StartUp Project" and F5; or right click, "Debug", "Start new instance"). In VS's debug output window, ignore any "first-chance exception" messages; it should say ".......OK!" if it succeeded.

Keeping up to date

After you've set everything up, the process for staying up to date is:

  • Update the root directory of the checkout.
  • Close the solution in Visual Studio if you've got it open. Run update-workspaces.bat again. (This is only needed if any source files have been added or removed. If you forget to run this, you'll probably get build errors about missing symbols.)
  • Build again.

Building Windows dependencies

By default windows come with prebuilt libraries but you might want to rebuild them yourself, to do so follow the instructions at BuildingWindowsDependencies.


0 A.D. should work on any reasonably modern Linux distro, on x86 and x86_64 (amd64). The details depend on exactly which distro you use.

Distributed C/C++ compiling (distcc)

If you have access to more than 1 computer on a LAN, you may want to consider using distcc to reduce the build time. If you use distcc, you must provide the --without-pch argument when running To get the maximum benefit, remember to increase the value of the number following the -j argument. For example, if distributing the build to 3 computers where each has 4 cores, try -j12 or -j15.


First you need to install various standard tools and development libraries:

  • a C++17 conforming compiler
  • LLVM-objdump, which is part of the LLVM binaries. You don't need clang itself.
  • the rust compiler and cargo (NB: A27 needs rust 1.51.0 and later won't work without)
  • Boost (at least 1.57 since r21726)
  • cargo
  • CMake (only needed if you use bundled NVTT)
  • Python 3 (required for cxxtest and non-system SpiderMonkey)
  • libcurl (at least 7.32)
  • libenet (1.3, the older 1.2 is not compatible)
  • libfmt (at least 4.0)
  • libgloox (needed for the lobby; at least 1.0.10, previous versions are know to have connection problems; pass --without-lobby to to exclude the lobby)
  • libicu
  • libogg
  • libpng
  • libsodium (>= 1.0.14, follow the instructions at if your distro is behind)
  • libvorbis
  • libxml2
  • miniupnpc (at least 1.6)
  • OpenAL
  • OpenGL
  • rustc
  • SDL2 (at least 2.0.2)
  • Subversion (or git if you want to use the Git mirror; see below)
  • zlib

To compile editing tools (enabled by default; pass the flag --disable-atlas to to disable):

  • wxWidgets (at least 3.0; packages are probably called wxgtk)

To use shared system libraries instead of bundled copies (default) of libraries (pass the flag --with-system-$COMPONENT to to use the non-bundled copy):

  • SpiderMonkey 91 (--with-system-mozjs)
  • NVTT (--with-system-nvtt) Note: the version of NVTT provided by your package manager is probably too old and we don't check it yet (#5757).

For a list of all options to see premake.

ArchLinux, Manjaro, Parabola

Install the dependencies with:

sudo pacman -S --needed awk openal m4 boost cmake curl enet fmt gcc gloox grep icu libgl libogg \
    libpng libsodium libvorbis libxml2 llvm make miniupnpc patch pkg-config python \
    rust sdl2 subversion wxwidgets-gtk3 zip zlib
Parabola i686

If building Atlas (happens by default), you will need to:

  • Change wxwidgets-gtk3 to wxgtk3 in the list above;
  • Set the WX_CONFIG variable, else the build process might fail outright or attempt to use the gtk2 frontend instead. For example, run this command before running
    export WX_CONFIG=wx-config-gtk3

If not correct, you will get errors about missing "wx/*.h" includes.

You can skip building Atlas altogether (and negate the wxWidgets dependency) by passing the --disable-atlas option to

Debian, Ubuntu

  • On Debian 12 (bookworm) or Ubuntu 23.04 (lunar) or later install the required dependencies with:
    sudo apt install build-essential cargo cmake libboost-dev libboost-system-dev   \
        libboost-filesystem-dev libcurl4-gnutls-dev libenet-dev libfmt-dev   \
        libfreetype-dev libfreetype6 m4 libfreetype6-dev   \
        libgloox-dev libicu-dev libminiupnpc-dev libnvtt-dev libogg-dev   \
        libopenal-dev libpng-dev libsdl2-dev libsodium-dev libvorbis-dev   \
        libwxgtk3.2-dev libxml2-dev python3 rustc subversion zlib1g-dev
  • If you want to use a packaged SpiderMonkey, which will be made available for example in PPA:
    • you should add libmozjs--dev and run with --with-system-mozjs.
  • When not using system nvidia-texture-tools, libnvtt-dev can be omitted, but cmake is needed to build the bundled NVTT.
  • You can also use libcurl4-openssl-dev instead of libcurl4-gnutls-dev (it's not possible to install both at once). Note that versions of openssl prior to 3.0.0 are not GPL compatible and those resulting binaries could not be redistributed.
  • On older Debian / Ubuntu versions you may have to replace libwxgtk3.2-dev with libwxgtk3.0-gtk3-dev.


Install the dependencies with:

sudo dnf install cargo cmake boost-devel enet-devel fmt-devel gcc-c++ \
    gloox-devel libcurl-devel libicu-devel libpng-devel libsodium-devel \
    libvorbis-devel libxml2-devel miniupnpc-devel openal-soft-devel \
    patch pkgconfig python SDL2-devel subversion wxGTK3-devel zip
  • To submit a patch for review via arcanist (Phabricator), php is needed: dnf install php-cli php-json php-xml.

After installing the dependencies for your particular version, you can build 0 A.D. from the svn code using the instructions from the Building section.

Note: These instructions have been tested on the 64-bit version of Slackware.

Slackware 14.2

If you've done the full install of Slackware, most of the dependencies are already installed. The other required dependencies you can install from the Slackbuilds repo using sbopkg:

  • enet
  • gloox
  • libsodium
  • miniupnpc
  • OpenAL
  • SDL2

Required to build Atlas:

  • wxGTK3 (install/build this first, required by wxPython3)
  • wxPython3

Default 14.2 packages:


Upgraded packages:


Special packages:


Kernel headers must match your kernel version.

Use the 0ad-data and 0ad slackbuilds from and this is fine for v0.0.23b . Newer versions require gcc>=7 so you'll have to use slackware-current or wait till slackware 15.0 comes out if you want to try them out.

Slackware 15.0

If you've done the full install of Slackware, most of the dependencies are already installed. The other required dependencies you can build and install from the Slackbuilds repo using sbopkg:

  • enet
  • fmt
  • gloox
  • miniupnpc
  • wxGTK3 (which has it's own dependencies)
    • webkit2gtk (which requires)
      • bubblewrap
      • geoclue2
      • xdg-dbus-proxy
      • wpebackend-fdo (which requires)
        • libwpe
  • 0ad-data

then build and install 0ad with the ATLAS=enable option for the map editor


Get the updated build scripts from:

Make the following modifications to both 0ad.SlackBuild and 0ad-data.SlackBuild build scripts:

Modify 0ad.SlackBuild to skip the build-tests: Old: build/workspaces/ \

--without-pch \ --bindir=/usr/games \ --datadir=/usr/share/games/0ad \ --libdir=/usr/lib${LIBDIRSUFFIX}/0ad \ --${ATLAS:-disable}-atlas

New: build/workspaces/ \

--without-pch \ --bindir=/usr/games \ --datadir=/usr/share/games/0ad \ --libdir=/usr/lib${LIBDIRSUFFIX}/0ad \ --without-tests \ --${ATLAS:-disable}-atlas


Optional way is without using SlaCkBuilds, not making a package. For keeping a local, constantly modified, rebuilt and custom patched version under /home/$(whoami)


Discussion of installing on CentOS 7 can be found on the forums here.

Note: The advice below is derived from installing in a Virtual Machine with CentOS 7 64-bit minimally installed. If you have CentOS 6 (or earlier), the following steps may not be possible. Installation on a physical machine, a machine with more stuff already installed upon it, or a machine that is 32-bit, may differ slightly.

  1. Firstly, you will need to enable the "Extra Packages for Enterprise Linux" (or "EPEL") repository (if you haven't already). You can do this by running (as root/via sudo) #!sh yum install epel-release
  1. Install some auxiliary packages. These are not dependencies of 0 A.D. itself, but are necessary to run successfully. They might already be installed on your system: #!sh yum install bzip2 patch
  1. Install the 0 A.D. dependencies that are available directly from repos: #!sh yum install cmake gcc-c++ enet-devel libglvnd-devel gloox-devel libicu-devel \ libogg-devel libpng-devel libsodium-devel libvorbis-devel libxml2-devel \ miniupnpc-devel openal-soft-devel subversion wxGTK3-devel zlib-devel SDL2-devel
  1. Acquire a sufficiently recent version of libcurl:
    • From this site:, download the two files that satisfy one of the following patterns:
      • libssh2-{version}.cf.rhel7.{arch}.rpm
      • libssh2-devel-{version}.cf.rhel7.{arch}.rpm
    • From this site:, download the three files that satisfy one of the following patterns:
      • curl-{version}.cf.rhel7.{arch}.rpm
      • libcurl-{version}.cf.rhel7.{arch}.rpm
      • libcurl-devel-{version}.cf.rhel7.{arch}.rpm
    • Install some dependencies from repos: #!sh yum install nss-devel libnghttp2 libpsl libmetalink
    • Install dependencies from downloaded packages.

      Note: This will replace the version of libssh2 that is provided by the CentOS official repos. This is necessary as the version of libcurl we're installing needs a more up-to-date version than what the official repos can provide. As the packages we've acquired are compiled as to be interoperable with CentOS systems, this shouldn't cause any problems with other programs installed on your system.

      Install the libssh2-* and libssh2-devel-* packages using rpm -Uvh. For example: #!sh rpm -Uvh
    • Install the updated curl packages (curl-*, libcurl-* and libcurl-devel-*) using rpm -Uvh. For example: #!sh rpm -Uvh
  1. Acquire a sufficiently recent version of boost:
    • From, download boost_1_70_0.tar.gz.
    • Uncompress archive:
      • $ tar -xf boost_1_70_0.tar.gz
    • Enter folder:
      • $ cd ./boost_1_70_0
    • Compile the parts that are needed to be compiled, and install the libraries:
      • $ ./ --with-libraries=filesystem,system
      • # ./b2 install
      • (Compiled files end up in /usr/local/lib/, header files in /usr/local/include/boost/)
    • Make sure the runtime linker can find the updated boost libraries:
      • Navigate to /etc/ and create a blank file called pyro.conf.
      • Within this file, enter the text /usr/local/lib and save.
  1. Acquire a sufficiently recent version of fmt:
  1. You should now have all dependencies for 0 A.D. Continue by getting the code, as described below. When you get to the part below in Building where you run ./, you must use the argument --prefer-local-libs.


sudo xbps-install -Syv base-devel boost-devel cmake curl fmt-devel gcc icu-devel libcurl-devel libenet-devel libogg-devel libopenal-devel libpng-devel libsodium-devel libvorbis-devel libxml2 MesaLib-devel miniupnpc-devel patch pkg-config SDL2-devel wxWidgets-devel zip zlib

If there are issues, install more header files depending on the compiler's error message. pyrogenesis requires MesaLib-devel to provide header files for libGL. Custom compile gloox for the Lobby or use xbps source packages or use --without-lobby. If there are unresolved shlibs or an update breaks a package, then e.g.

sudo xbps-install -Syv SDL2-devel dbus dbus-x11  # credit Vaelatern
sudo xpbs-install -Su  # update, add -d for debugging, credit duncaen

Getting the code

See Getting the Code.


Compile the code with:

cd 0ad/build/workspaces
./ -j3
cd gcc
make -j3
  • -j3 gives the number of parallel builds to run, and should typically be one plus the number of CPU cores available.
  • The Release mode builds (which are the default) are more optimised, but are harder to debug. Use make config=debug (and run pyrogenesis_dbg) if you need better debugging support. See Debugging for more details.

If you encounter any build errors, review the existing bug reports, check the known problems section or please file a new bug in the tracker.


Run the automated tests to verify that everything works as expected like this:

cd ../../..


If everything went well, compiling the code worked and all tests passed, it's finally time to run the game:


Keeping up to date

If you want to rebuild quickly after updating from SVN, you can usually get away with:

svn up
cd build/workspaces
./ -j3
cd gcc
make -j3

If the make line gives errors, you may need to run make clean before it. If the gives errors, you may need to run before it.

Creating Linux packages

If you want to create packages for a Linux distribution see the current 0ad and 0ad-data packages on Salsa for examples (especially the control and rules files).

#!comment Keep anchor for convenient fragment links to the former "OS X" heading.


The process on macOS is similar to Linux:


  1. Install Xcode, version 10.1+ is recommended. Only 10.13+ are supported to compile the game.
  2. Install the command line tools for Xcode:
    • Open a Terminal window and enter xcode-select --install.
  3. Install the rust toolchain.
  4. CMake:
    • (recommended) If you have Homebrew installed, use `brew install cmake`.
    • Alternatively, download a prebuilt macOS package at If prompted, choose to install the "CMake command line tools" to the default location.
      • Note: Recent versions have no installer, so after copying the app bundle to Applications, you need to run CMake with elevated permissions to install the command line tools. From the terminal: sudo "/Applications/" --install.
      • If the install command fails, you can manually add the following line to the end of /etc/paths: /Applications/

Getting the code

See Getting the Code.

Now you have two options:

Build the game

  • Run libraries/osx/, the macOS libraries build script, this will download and build the game's dependencies (except CMake, see above). This script will take some time to finish when first run, after that it will reuse the old build.
    cd libraries/osx
    ./ -j3
    • -j3 gives the number of parallel builds to run, and should typically be one plus the number of CPU cores available.
    • To force a rebuild for some reason, e.g. the SVN folder is moved or Xcode / macOS is upgraded, pass in the --force-rebuild flag.
  • Next, to build the game on the command line, use the following commands:
    cd build/workspaces
    ./ -j3
    cd gcc
    make -j3
  • Or if you have Xcode 4 installed, you can open build/workspaces/xcode4/pyrogenesis.xcworkspace (see discussion on this here).
  • Run the automated tests to verify that everything works as expected like this:
  • If everything went well, compiling the code worked and all tests passed, it's finally time to run the game:

macOS Troubleshooting

  • Building Spidermonkey: Install a python version known to work. Up-to-date 3.7, 3.8, 3.9 and 3.10 are confirmed to work, though versions shipped with older mac systems (e.g. 3.8.2 on macOS 10.15) might not.

Create macOS distributable app bundle

This is outdated and will soon change.

  • You will need Xcode installed (for its SDKs)
  • Open build/workspaces/ and read the comments. You will need to change a few settings depending on your version of macOS, Xcode, etc.
  • Run, the bundle build script, which will download and build the game's dependencies for the appropriate SDK, build the game's source code, package the mod data, and set up the app bundle info.
    cd build/workspaces
    ./ -j3
  • -j3 gives the number of parallel builds to run, and should typically be one plus the number of CPU cores available.
  • When it's finished, there should be a complete 0ad app bundle in build/workspaces. You can open it by double-clicking its icon in Finder or with the open command in the terminal.
  • Consider the following to make an official release:
    • Use --release, to create a bundle from a clean SVN working copy.
    • Package the bundle inside a compressed DMG with background image, for easy distribution (see ReleaseProcess).


Note: The *BSD support is a work in progress and should be considered experimental. That means don't try it unless you "know what you're doing" :)

TODO: outdated, please update (see #5255)

  • Install the following ports or packages (names probably differ depending on the BSD variant):
    Install commands for the variants are provided below.
    • boost-libs
    • cmake
    • curl (at least 7.32)
    • enet
    • execinfo
    • gloox
    • gmake
    • iconv
    • icu
    • libGL
    • libogg
    • libvorbis
    • libxml2
    • miniupnpc
    • openal
    • png
    • sdl2
    • subversion
    • wxWidgets-gtk2 (3.0 and above) - required to build the Atlas editor
    • zip
    • Note: zlib should already be installed by default
    • GCC 4.8.1+ or Clang
  • Obtain the game's source code as described above for Linux.
  • Check for any variant specific issues below.
  • Note: Our build scripts should detect that you are running *BSD and use gmake as the make command. If for some reason this isn't correct, you can set the MAKE environment variable to the correct GNU make path.
  • Follow the build instructions above for Linux.


  • Install the dependencies with:
    pkg install boost-libs cmake curl enet fmt gloox gmake iconv libGL libogg          \
         libsodium libvorbis libxml2 miniupnpc openal pkgconf png sdl2 subversion        \
         wx30-gtk2 zip
  • If running FreeBSD 10.0+ you need to set CC to clang and CXX to clang++.
    export CC=clang CXX=clang++
  • If building Atlas, you need to set the WX_CONFIG variable, because wx-config has a different name on FreeBSD. For example, you'd run this command if you built the wxGTK 2.8 package with unicode support:
    export WX_CONFIG=wxgtk2u-2.8-config
    if not correct, you will get errors about missing "wx/*.h" includes. You can skip building Atlas altogether (and the wxWidgets dependency) by later passing the --disable-atlas option to
    • You'll have to set this variable every time you run, so it may be most convenient to put these commands into another shell script.


OBSOLETE, NEEDS UPDATING why FreeBSD has clang suggested, but OpenBSD egcc...

  • You need to set CC and CXX before building
    export CC=egcc CXX=eg++
  • Install the dependencies with:
    pkg_add -i boost cmake curl enet fmt g++ gcc gloox gmake icu4c libexecinfo libogg \
        libsodium libxml miniupnpc openal png sdl2 subversion zip
  • As OpenBSD's packaged libxml isn't build with threading support, building Atlas is not possible so you should run with the --disable-atlas option.
  • You probably need to run pyrogenesis with LD_PRELOAD=/usr/local/lib/ (see #1463).

Known problems and solutions

  • None currently.
