CGAL users discussion list

Hi,
Yes I use the Debian package. That means I can not use Leda and Taucs?

The error message below arrives on every demo or example I want to open. The 
cmake and make is working.

                                                  ^^^^^^^^^^^^^^^

it would be helpful if you would tell which demo you tried to execute.
Please attach all the output of the demo compilation process.

Do you now use your self-build CGAL or the Debian packages. Note that
the Debian package have no support for LEDA and TAUCS (since these
packages are not in Debian). If you use your self-build CGAL you should
deinstall the Debian packages (or make sure that you don't mix them,
e.g. the error message above references /usr/include/CGAL/Interval_nt.h).
