Hi,

Thanks for your response.
My CGAL version is 3.5.1-1, I just installed it earlier today. I changed the piece of code that didn't compile by the one given in the online documentation proper to my version. It compiled well... but did not execute. I got this error :

terminate called after throwing an instance of 'CGAL::Assertion_exception'
what():  CGAL ERROR: assertion violation!
Expr: m_primitives.size() > 1
File: /usr/include/CGAL/AABB_tree.h
Line: 471
Abandon

Is there any way to solve it?

By the way, how can I get the latest version of CGAL installed by the command line sudo apt-get...? That would be an alternate solution to my problem since there is no namespace error with Joachim's version (3.6.1-1).


Thanks for any feedback,

Valentin

unfortunately you do not tell us which version of libcgal-dev you
installed. It works for me with libcgal-dev 3.6.1-1.

By the way you can also install libcgal-demo which gives you all
examples and demos in /usr/share/doc/libcgal-demo. Maybe you have an
older version of CGAL installed, and the example at the above URL is too
new for you. Older versions contain that example as well, maybe with
minor differences.

Or browse the online documentation and replace "beta" in the URL with
your CGAL version.
