关于Boost中has_new_operator.hpp文件的问题以及CGAL文?报错
1，刚开始学习使用CGAL，主要用到了Boost库，使用VS2012建了一个MFC项目，添加include如下：
#include <CGAL/Simple_cartesian.h> #include <CGAL/Polyhedron_3.h> #include <CGAL/IO/Polyhedron_iostream.h> // #include <CGAL/Surface_mesh_simplification/HalfedgeGraph_Polyhedron_3.h>
#include <CGAL/Surface_mesh_simplification/edge_collapse.h> #include <CGAL/Surface_mesh_simplification/Policies/Edge_collapse/Constrained_placement.h> #include <CGAL/Surface_mesh_simplification/Policies/Edge_collapse/Midpoint_placement.h> #include <CGAL/Surface_mesh_simplification/Policies/Edge_collapse/Count_stop_predicate.h> //#include <CGAL/Surface_mesh_simplification> #include <CGAL/Unique_hash_map.h> #include <CGAL/Mesh_3/dihedral_angle_3.h> #include <CGAL/property_map.h> #include <cmath>
运行时出现如下错误：
错误 2 error C2064: 项不会计算为接受 2 个参数的函数 d:\boost\boost_1_54_0\boost\type_traits\has_new_operator.hpp 33 1 app2 错误 3 error C2064: 项不会计算为接受 2 个参数的函数 d:\boost\boost_1_54_0\boost\type_traits\has_new_operator.hpp 44 1 app2 错误 4 error C2064: 项不会计算为接受 2 个参数的函数 d:\boost\boost_1_54_0\boost\type_traits\has_new_operator.hpp 55 1 app2 错误 5 error C2064: 项不会计算为接受 2 个参数的函数 d:\boost\boost_1_54_0\boost\type_traits\has_new_operator.hpp 67 1 app2 错误 7 error C2059: 语法错误:“]” d:\boost\boost_1_54_0\boost\type_traits\has_new_operator.hpp 67 1 app2 错误 8 error C2059: 语法错误:“)” d:\boost\boost_1_54_0\boost\type_traits\has_new_operator.hpp 69 1 app2 错误 9 error C2649: “typename”: 不是“class” d:\boost\boost_1_54_0\boost\type_traits\has_new_operator.hpp 70 1 app2 错误 10 error C2649: “typename”: 不是“class” d:\boost\boost_1_54_0\boost\type_traits\has_new_operator.hpp 73 1 app2
//has_new_operator.hpp
namespace detail {
template <class U, U x>
struct test;
template <typename T>
struct has_new_operator_impl {

static type_traits::yes_type check_sig1(
U*,
test<
void *(*)(std::size_t),
&U::operator new //项不能计算为接受两个参数的函数
>* = NULL
);
但是当我把把关于Surface_mesh_simplification的include注释掉之后就不会报错了，如下：
#include <CGAL/Simple_cartesian.h> #include <CGAL/Polyhedron_3.h> #include <CGAL/IO/Polyhedron_iostream.h> // //#include <CGAL/Surface_mesh_simplification/HalfedgeGraph_Polyhedron_3.h> //#include <CGAL/Surface_mesh_simplification/edge_collapse.h> //#include <CGAL/Surface_mesh_simplification/Policies/Edge_collapse/Constrained_placement.h> //#include <CGAL/Surface_mesh_simplification/Policies/Edge_collapse/Midpoint_placement.h> //#include <CGAL/Surface_mesh_simplification/Policies/Edge_collapse/Count_stop_predicate.h> //#include <CGAL/Surface_mesh_simplification> #include <CGAL/Unique_hash_map.h> #include <CGAL/Mesh_3/dihedral_angle_3.h> #include <CGAL/property_map.h> #include <cmath>
求解？
2，CGAL读的是OFF格式的文件（ASCII或者Binary），但是为什么我用Maya生成的obj文件转化成off格式的文件之后为什么CGAL不能计算？
参考代码如下（obj-->off）：
using namespace std;
// TODO: 在此添加命令处理程序代码
