Hello everybody out there!

        Well, I have received it anyway, thank you.

        I have been able to compile and run it (I just add “#include
<iostream>” at the beginning of “main.cpp”). Here is the result of the run:

$ ./main
#veterx=3
#faces=1

        The result is the one expected.

        Still, I have this compilation error on my own code:

/home/lebarsy/Codes/UWWatch-test/src/gmsh.cpp:131:27: error:

member named ‘set_point’

        I am investigating it, but I have not found what is wrong yet.

        Just to let you know, here are my definitions:

/// \brief Type for CGAL mesh kernel.
typedef CGAL::Exact_predicates_inexact_constructions_kernel K;
/// \brief CGAL 2D points type.
typedef K::Point_2 Point;
/// \brief CGAL 3D points type.
typedef K::Point_3 Point3;
/// \brief Allows for using 2D algorithms on the 3D points.
typedef CGAL::Projection_traits_xy_3<K> Gt;
/// \brief Vertex class.
typedef CGAL::Triangulation_vertex_base_2<Gt> Vb;
/// \brief Custom face class, use default face and vertex as required.
typedef CGAL::Constrained_triangulation_face_base_2<Gt> Fb;
/// \brief Type for 2D triangulation with CGAL.
typedef CGAL::Triangulation_data_structure_2<Vb, Fb> Triangulation;
/// \brief Mesh vertex type.
typedef Triangulation::Vertex_handle Vertex;

        And here are the lines that cannot be compiled:

// Mesh vertices set.
std::vector<Vertex> vertex (x.size());
for (std::size_t i = 0; i < x.size(); ++i) {
    // Current point coordinates.
    const Point p (x[i], y[i]);
    vertex[i] = mesh.create_vertex();
    vertex[i].set_point(p);
}

        I have already tested without using “const” when creating “p” and 
using
“Point3” rather “Point”, the error is still the same.

        Well, as I have a running example, I should be able to solve the 
problem.

        Best regards.
