Getting the code

Windows

Git

• Download and install ​TortoiseGit. (Make sure you reboot when it asks you to.)

Subversion (SVN)

• Download and install ​TortoiseSVN. (Make sure you check the "command line client tools" option and reboot when it asks you to.)

macOS

• Git is part of the Xcode Command Line Tools package, and can be installed via the GUI or the terminal.

  xcode-select --install
  

• SVN is no longer part of the Xcode Command Line Tools package, but can be installed, e.g. via ​Homebrew.

  brew install svn
  

Linux

Git

Git is usually present on modern distributions of Linux however you might need to install it in some cases. Depending on your Linux flavour your package manager might differ. For instance on Ubuntu it would be:

sudo apt update
sudo apt install git

Subversion (SVN)

You might need to have to install subversion for it to work. Depending on your Linux flavour your package manager might differ. For instance on Ubuntu it would be:

sudo apt update
sudo apt install subversion

All platforms

You'll need approximatively 8GB for a clean checkout, and a few more if you build and run the game. So try to have at least 20GB free to be safe.

Note: 0 A.D. is primarily developed on SVN. However since we are using Arcanist and Phabricator, unless you have commit access you should never need to use SVN if you don't want to. You can use Git instead using mirrors, those may be slightly less up-to-date but usually offers faster downloads. Those mirrors are updated daily.

Important: Make sure that the checkout directory doesn't contain special characters (spaces or non-ASCII characters)

Git

To use a Git mirror, use one of the following commands:

git clone https://github.com/0ad/0ad.git

or

git clone https://gitlab.com/0ad/0ad.git

As of February 2024, the Git repo consumes about 9 GB of disk space. Consider using --depth=50 or something like that if you don't plan to compile previous versions.

Subversion (SVN)

To checkout the latest code from SVN, run this command:

svn co https://svn.wildfiregames.com/public/ps/trunk/ 0ad

Note: This is the read-only public SVN URL. If you have commit access, you need to use this one instead:

svn co https://svn.wildfiregames.com/svn/ps/trunk/ 0ad

Note: Sometimes SVN stops before it has downloaded all files. You should check that it outputs something like at revision rXXXXX. Otherwise run

svn cleanup 0ad
svn up 0ad
