Hi all

I'm currently trying to reconstruct some meshes based on a xyz point set
without normals. 
Managed to do it with normals_example and poisson_reconstruction_example,
but when I am trying to merge them together, the errors occur as follows:


1>c:\program files\cgal-4.2-beta1\include\cgal\kernel_traits.h(33): error

Here I use <Point, Vector>  to represent the points with normals and use the
First_of_pair_property_map and Second_of_pair_property_map as the parameters
in the poisson function. Attached is the combined code.

I have no ideas about what is wrong. 
Any help will be greated appreciated. surfacewithoutnormal.cpp
