Downloading Jazz++
Currently, only a source tarball is available. You would probably have more success attempting to build the source in Subversion. We simply aren't ready to produce binary distributions yet. If you still want to give the source tarball a try, you first need to create a non-stock build of wxWidgets 2.8.7 to build Jazz++. View the Building wxWidgets page for details.
Download the Jazz++ source tarball from sourceforge.
