CGAL users discussion list

I can see you have a 64bits machine. Mine is 32.
I try on a 64bits machine and still you code ran without
assertion failure.

Did you used cmake to build CGAL?
can you try using cmake to generate the makefile to compile
your example (you can use the script cgal_create_cmake_script to
generate a CMakeLists.txt)
