Online OsiriX Documentation/OsiriX Anonymous and Developer SVN access
In order to check out (fetch an initial copy) of the OsiriX source code, you need to have Subversion installed.
Anonymous access is simple if you don't plan to submit any changes to the project. Open up Terminal. cd to a root directory to check out your code. Mine is /Users/spalte. Then type: svn co https://osirix.svn.sourceforge.net/svnroot/osirix osirix
This will then chunder for a while and you will end up with a directory called osirix containing the source ie for my setup /Users/spalte/osirix. Now you are ready to build the project.
When the download is complete open the project in x-code, then select the unzip binaries target and build this and then build the development target.
