Hi everyone,

This is a snippet of what I need:

#include <CGAL/Exact_predicates_inexact_constructions_kernel.h>
#include <CGAL/Mesh_3/Robust_intersection_traits_3.h>
#include <CGAL/Mesh_triangulation_3.h>
#include <CGAL/Mesh_complex_3_in_triangulation_3.h>
#include <CGAL/Mesh_criteria_3.h>
#include <CGAL/Polyhedral_mesh_domain_3.h>
#include <CGAL/make_mesh_3.h>
#include <CGAL/refine_mesh_3.h>
#include <CGAL/IO/io.h>
#include <CGAL/IO/Polyhedron_iostream.h>
#include 
#include "Config.h"
#include "IteraFormatos.h"


typedef CGAL::Exact_predicates_inexact_constructions_kernel K;
typedef CGAL::Mesh_3::Robust_intersection_traits_3 Geom_traits;
typedef CGAL::Polyhedron_3 Polyhedron;
typedef CGAL::Polyhedral_mesh_domain_3<Polyhedron, Geom_traits> Mesh_domain;
#ifdef CGAL_CONCURRENT_MESH_3
    typedef CGAL::Mesh_triangulation_3<
    Mesh_domain,
    CGAL::Kernel_traits::Kernel, // Same as sequential
    CGAL::Parallel_tag // Tag to activate parallelism
    >::type Tr;
    #else
    typedef CGAL::Mesh_triangulation_3::type Tr;
#endif
typedef CGAL::Mesh_complex_3_in_triangulation_3 C3t3;
typedef CGAL::Mesh_criteria_3 Mesh_criteria;

using namespace CGAL::parameters;    
using namespace std;



int main() {
    //information about the mesh
    Config objConfig;
    IteraFormatos objIteraFormatos(objConfig); 

    Polyhedron polyhedron;
    ifstream input(objConfig.get_surf_mesh_path().c_str());
    input >> polyhedron;

    Mesh_domain domain(polyhedron);

    Mesh_criteria criteria(facet_angle = 5, facet_size = 0.90, facet_distance = 0.03, cell_radius_edge_ratio = 2);

    C3t3 c3t3 = CGAL::make_mesh_3(domain, criteria, no_perturb(), no_exude());  

    ofstream c3t3_save("test.c3t3"); 
    c3t3_save<<c3t3.triangulation(); 
    c3t3_save.close(); 
    C3t3 new_c3t3;
    ifstream c3t3_load("test.c3t3");
    c3t3_load >> new_c3t3.triangulation();    
    return 0;
}

but I get dozens of errors, starting with these:
