You can choose to download either the latest stable release, or the current development version (frequently updated).

Stable release

Download the source code distribution from Sourceforge, then unpack the directory with

gunzip < madagascar-*.tar.gz | tar xvf -


bunzip2 < madagascar-*.tar.bz2 | tar xvf -

The bz2 file is a bit smaller, but takes longer to unpack.

Next, follow Installation instructions to install.

Current development version

To download the most recent Madagascar source code, you need to have a Subversion client (svn) installed. If you want to download it read-only, run the following command:

svn co RSFSRC

Replace RSFSRC with the path where you want to put the Madagascar source code. If you are a Madagascar project contributor and you want to download it in read-write mode, use

svn co \
--username=<your_sourceforge_username> \
svn+ssh://<your_sourceforge_username> \

Next, follow Installation instructions to install.

You can also browse the Subversion repository.


To update the Madagascar source code on your computer with the changes made by developers, cd to the directory where you placed the sources and run

svn update


  • If, after running the svn co... command, nothing happens, no message, no return to the command line: you may be behind a proxy. This is especially likely if your computer is on a corporate Intranet. To get past a proxy, you need to tell Subversion: (1) The IP number or URL of the proxy and (2) the port that will allow svn through – most likely 80, the standard HTTP port. Open your ~/.subversion/servers file in a text editor. If this file does not exist, running any svn command (even an unsuccessful one, like the one above) will automatically create the file. In the [global] section, add the following lines, with your own proxy URL and port names instead of the dummy ones below:
http-proxy-host =
http-proxy-port = 80

Now your svn commands should work. You can find more details in the Subversion documentation. It would also be a good idea to set in your .bashrc or .cshrc the environment variable HTTP_PROXY to your adaptation of

so that input datasets for reproducible figures can be downloaded automatically when you need them.

  • If you get a "is already a working copy for a different URL" error, this means you have an existing directory downloaded from another server. Run svn switch --relocate to switch servers.
  • If you are using an old Linux distribution (e.g. RedHat 9), the version of Subversion included with your distribution may need to be updated to handle the secure URL (https://). If svn complains about an "unrecognized URL scheme" (and you've given it the correctly formatted URL), then you need to update it.
  • If you are behind a firewall, you may need to set up more variables in your file ~/.subversion/servers (check with your IT support for all the required variables to get past the proxy) as for example
http-proxy-host = 
http-proxy-port = 1111
http-proxy-username = Yourusernameforproxy
http-proxy-password = Yourpasswordforproxy 

It would be a good idea then to protect your file ~/.subversion/servers from being read by others.

Other packages

There are two other packages that might be useful in conjunction with RSF:

Reproducible figures

Using Subversion, run

svn co $RSFROOT/share/madagascar/figs 

This installs a wide collection of more than 5,000 reproducible figures. It may take a long time to download and more than 6 Gb of disk space. The figures are preserved with the purpose of regression testing whenever the software or the environment change.

You can reproduce the figures (excluding those generated with proprietary data or additional software) by running scons lock in individual project directories or by going to RSFSRC and running

sfbooklist command="scons lock" book

LATEX package

SEGTeX is a LaTeX package for geophysical publications. It can be used with madagascar for writing reproducible papers.
