如何解决：error C2039: 'make_normal_of_point_with_normal_pmap': is not member of 'CGAL'

Question

我正在使用 CGAL 4.12 和 eigen 3.3.4 并尝试通过 Matlab mex 函数编译 Poisson_surface_reconstruction_3 示例，但出现以下错误：

C:\Users\u0116401\Documents\PRosPeRoS\Matlab_Code\mexTest\CGAL_poisson_reconstruction.cpp(70): error C2039: 'make_normal_of_point_with_normal_pmap': is not a member of 'CGAL'
C:\dev\CGAL-4.12\include\CGAL/IO/read_xyz_points.h(40): note: see declaration of 'CGAL'
C:\Users\u0116401\Documents\PRosPeRoS\Matlab_Code\mexTest\CGAL_poisson_reconstruction.cpp(70): error C3861: 'make_normal_of_point_with_normal_pmap': identifier not found

好像'make_normal_of_point_with_normal_pmap'找不到了。有谁知道是什么导致了这个问题？

产生此错误的代码是：

该函数名为 make_normal_of_point_with_normal_map()（map 而不是 pmap），它使用 Point_with_normal 作为参数。调用应该是：

CGAL::make_normal_of_point_with_normal_map(Point_with_normal())
