CGAL users discussion list

["J. Scheurritch" <>]

i am trying to use cgal in one of my Xcode projects. 

I made many attempts now since the last three days, but i always end up having many compilation errors, which are really hard to understand…

First i installed CGAL as stated here: https://doc.cgal.org/latest/Manual/usage.html by using home-brew:

brew install cgal

which worked perfectly and didn’t show any errors.

As i already set the user search paths to /usr/local/include and /usr/local/lib, i could directly use the CGAL headers in my project.

After trying some basic functions with the library i tried to do follow the surface reconstruction tutorial:

I figured out, that some functions would work and some not, for example:

CGAL::compute_average_spacing<CGAL::Sequential_tag> (points, 6);

      would work perfectly with a
          list of points, but: 
      
        
      
        CGAL::jet_smooth_point_set<CGAL::Sequential_tag> (points, 24);
        
          
        would result in many
            errors like: “Static_assert failed due to
            requirement’!(boost::is_same<CGAL::GetSvdTraits…."
        or: “No matching
            function for call to object of type ‘Monge_jet_fitting
            (aka ‘Monge_via_jet_fitting…..”
        
          
        
        
        
        
        I followed this tutorial on installing CGAL
          in Xcode: https://3d.bk.tudelft.nl/ken/en/2016/03/16/using-cgal-and-xcode.html
        but since CGAL is header only those
          libraries don’t exist anymore. 
        
        
        To solve that problem, I could build CGAL
          with using cmake and add the missing libraries from that
          tutorial to my project, but this would not change anything.
        
        
        
        
        
        
        If i download the examples folder and try to
          build with cmake, everything works perfectly. The only problem
          is,
        that i don’t know what is missing for my
          Xcode project to use CGAL functions.

CGAL now requies --std=c++14

in the clang commandsline.
