Question

我希望使用CGAL生成具有特征的3D网格。我可以从CGAL :: Polyhedral_mesh_domain_3生成3D网格而没有任何问题。但是，当我尝试从CGAL :: Polyhedral_mesh_domain_with_features_3创建网格时，我收到以下错误：

Undefined symbols for architecture x86_64:

所有其他CGAL功能都在编译和正常工作，这只是一件事。我通过自制软件/ macports安装了CGAL（两者都给出了同样的错误）。我不确定我哪里出错了。我真的很感激有关如何排除故障的任何建议。

Typedef：

typedef double Real; 
typedef CGAL::Exact_predicates_inexact_constructions_kernel Kernel; 
typedef CGAL::Mesh_3::Robust_intersection_traits_3<Kernel> IGT; 
typedef CGAL::Polyhedron_3<IGT, My_items> Polyhedron; 
typedef Polyhedron::HalfedgeDS HalfedgeDS; 
typedef CGAL::Point_3<Kernel> Point; 
using namespace std; 

//Volume Mesh 
typedef CGAL::Mesh_polyhedron_3<IGT>::Type Mesh_polyhedron; 
typedef CGAL::Polyhedral_mesh_domain_with_features_3<IGT, Polyhedron> MeshDomain; 
typedef CGAL::Mesh_triangulation_3<MeshDomain>::type Tr; 
typedef CGAL::Mesh_complex_3_in_triangulation_3<Tr,MeshDomain::Corner_index,MeshDomain::Curve_segment_index> C3T3; 
typedef CGAL::Mesh_criteria_3

创建体网格：

using namespace CGAL::parameters; 
Mesh_Domain domain(mesh_Poly); 
domain.detect_features(); 
Mesh_Criteria criteria(facet_angle=30, facet_size=0.1, facet_distance=0.025, cell_radius_edge_ratio=2, cell_size=0.1); 
c3t3 = CGAL::make_mesh_3<C3T3>(domain, criteria); /* Error occurs here */
