Hello all,

I have just installed CGAL 4.4, and I am playing with the example:

http://doc.cgal.org/latest/Convex_hull_d/classCGAL_1_1Delaunay__d.html

My code is:

https://github.com/acgetchell/CDT-plusplus/blob/Delaunay_d/dSimplex.cpp

However, I get errors with leda_integer:

Any suggestions welcome.

Thank you.
