Aha, thank you Sebastien!

Swapping out GMP fixes this.

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.

Hello all,

The example listed here:

Chapter_main.html#Subsection_27.6.3

Looks like it generates a tetrahedron.

What is the best way for generating 4-simplices and storing them?

You can use a 4D combinatorial map, and write a function that create a
4-simplex by creating 4 tetrahedron (thanks to the function
CGAL::make_combinatorial_tetrahedron<CMap>) and use 3-sew to glue them
correctly.

Thanks to this function you can create several 4-simplices and use 4-sew
operation to glue them.

Note that if you need geometry, you need to use a 4D linear cell complex
instead of a 4D combinatorial map.

Guillaume

Thanks for any pointers,

Adam
