The latest version of mgl (2.0) can be retrieved using subversion:

svn checkout http://gru.brain.riken.jp/svn/mgl/trunk mgl

We recommend using subversion (see here for a quick primer) if at all possible. Mac OS 10.5-7 comes with subversion preinstalled. The latest versions of Mac OS 10.8 (Mountain Lion) does not have svn preinstalled. You can install svn by installing the latest Xcode (make sure that you have checked the option to install the command line tools to get svn - if you already have Xcode installed, but svn is not installed, go to Xcode > Preferences > Downloads > Command Line Tools > Install). You will also need to have Xcode installed if you need to recompile mgl. If these options fail, you can install svn directly from the subversion website. If you are really unable to get subversion, you can download mgl.tar.gz which contains a current version of the code. It should just open by clicking on it. If not, from a command line, you should be able to do:

gunzip mgl.tar.gz
tar xfv mgl.tar

Once you have downloaded, see Initial setup for installation instructions.

If you have problems downloading with svn because your institution has a proxy server, you might have to let subversion know about it. Have a look at download_with_proxy-server for details on how to set this up.

You can access a stable read-only version of mgl (version 1.5) by using subversion:

svn checkout http://gru.brain.riken.jp/svn/mgl/branches/v1_5 mgl

We are no longer making updates to version 1.5
