I did not find CGAL examples for compilation under Mac OS X 10.9 (Mavericks). You can successfully compile the CGAL 4.3 core library and also link it, but when using certain types of library I get errors, as shown below.
In particular, I was interested in using the example Surface_reconstruction_points_3 , which I tried to build from the beginning, getting this error:

To get very specific, I was really interested in the CGAL::make_normal_of_point_with_normal_pmap and created a test case just to try and use it. However, I get an error when compiling this code (below).

And the corresponding error message:

As expected, the standard way to build all the examples also causes errors (here I tried to build all the CGAL examples). To get there, I used cmake to build the CGAL 4.3 library from the source and enable WITH_examples in the settings. When compiling, I called make and make examples , which led to this error:

After all, if you know how to make make_normal_of_point_with_normal_pmap function work again, that would be great. I do not need to create all the examples, but I would like to use this part of CGAL . Thanks!
