Hi Laurent, 

Yes that's true. It is same as 

poisson_reconstruction_example.cpp example.

I am able to compile the example in the directory

examples/Surface_reconstruction_points_3/ however

I am interested in using these function in my own code and 

when I try to compile there it gives the following error. 

Any suggestions towards diagnosing the issue ?

Thanks, 

Hardik Kabaria

Dear Hardik,

The code below seems a cut and paste of CGAL's poisson_reconstruction_example.cpp example.
Does poisson_reconstruction_example.cpp compile properly on your machine?

Best regards,
Laurent Saboret

Hello, 

I am having some issues compiling an example from Surface reconstruction 

part. It'd be great if someone can point out what could be the issue. 

I am using Mac OS 10.8 and cgal 4.4

dn525jo5:poisson_rec hardik$ port list cgal

Warning: port definitions are more than two weeks old, consider updating them by running 'port selfupdate'.
