Can you please send us your command line, and the complete log, until "Segmentation fault" happens?

Are you using the Polyhedral_mesh_domain constructor that takes a filename as parameter?

Good question.

I am using CGAL-4.7

Are you both sure to use the same releases of CGAL?

Thank you for your answer.

So you say you were able to produce a valid out.mesh file with the .off
file I suggested ?

I just checked on my Ubuntu computer, and it does the same as this
afternoon at work on a Mac OS X. The error message here is

Erreur de segmentation (core dumped)

If I remember correctly, on the mac, it was something like

Segmentation fault:11

I have added the verbose line you sent me, and it does not tell me
anything else...

    Hi Timothee,

    I could not reproduce your seg fault.

    You can try to add the following macro definition on the very first
    line of your cpp file :
    #define CGAL_MESH_3_VERBOSE

    and then post the execution log?

    This could help you or us find the error.


    Also, you mention an "error message". What does it say ?

    Best,

    Jane.

        Dear all,

        I am trying to produce a 3D tetrahedral mesh from a boundary
        surface mesh. I
        figured that the easiest way to do this was to use a .OFF file of my
        boundary, which does not seem too difficult to produce, and feed
        it directly
        to this example program

        http://doc.cgal.org/latest/Mesh_3/Mesh_3_2mesh_polyhedral_domain_8cpp-example.html

        Before taking on my actual boundary surface mesh, I need to
        understand
        exactly what I am doing, so I tried replacing the file
        elephant.off with the
        following simple .off file representing a pyramid

        OFF
        5 6 0

        0.0 0.0 0.0
        1.0 0.0 0.0
        1.0 1.0 0.0
        0.0 1.0 0.0
        0.5 0.5 1.0
        3 2 1 0
        3 3 2 0
        3 0 1 4
        3 1 2 4
        3 2 3 4
        3 3 0 4

        Unfortunately this produces a segmentation fault when making the
        mesh. I
        have no idea what causes it to malfunction. Anyone has a clue ?
        I have also
        tried with a simple tetrahedron or a cube with each face cut
        into two
        triangles, same error message.

        Best

        Timothee
