CGAL users discussion list

[Richard Downe <>]

According to some of the documentation on the website, a handful of 
older demos still use Qt3, and due to dependency on an unmaintained 
custom widget have no migration plan.  Thus as I understand it, you can 
either disable building of the demos, and then return later and 
individually build the ones you're interested in, or you can install 
Qt3, whether via an apt repository or a custom build.

Ubuntu does have official CGAL packages, though afaik they haven't 
gotten to 4.1 yet.
