Hello

Ok, before I forgot to add the include, 
#include <CGAL/Exact_spherical_kernel_3.h>

but it seems like a linker error,rather than a missing include.

Anyway, following your suggestions, the new code is:

#include <CGAL/Spherical_kernel_intersections.h>           

CGAL::Exact_spherical_kernel_3::Line_arc_3 cgal_seg;                          
                                                                     
CGAL::Exact_spherical_kernel_3::Sphere_3 cgal_sphere;
CGAL::intersection(cgal_seg, cgal_sphere);

And I continue to have the same undefined function error ...

error: no matching function for call to
‘intersection(CGAL::Spherical_kernel_type_equality_wrapper<CGAL::internal::Spherical_kernel_base_ref_count&lt;CGAL::Spherical_kernel_3&lt;CGAL::Cartesian&lt;CGAL::Gmpq>,
CGAL::Algebraic_kernel_for_spheres_2_3<CGAL::Gmpq> >,
CGAL::Cartesian_base_ref_count<CGAL::Gmpq,
CGAL::Spherical_kernel_3&lt;CGAL::Cartesian&lt;CGAL::Gmpq>,
CGAL::Algebraic_kernel_for_spheres_2_3<CGAL::Gmpq> > > >,
CGAL::Spherical_kernel_3<CGAL::Cartesian&lt;CGAL::Gmpq>,
CGAL::Algebraic_kernel_for_spheres_2_3<CGAL::Gmpq> > >::Line_arc_3&,
CGAL::Type_equality_wrapper<CGAL::internal::Spherical_kernel_base_ref_count&lt;CGAL::Spherical_kernel_3&lt;CGAL::Cartesian&lt;CGAL::Gmpq>,
CGAL::Algebraic_kernel_for_spheres_2_3<CGAL::Gmpq> >,
CGAL::Cartesian_base_ref_count<CGAL::Gmpq,
CGAL::Spherical_kernel_3&lt;CGAL::Cartesian&lt;CGAL::Gmpq>,
CGAL::Algebraic_kernel_for_spheres_2_3<CGAL::Gmpq> > > >,
CGAL::Spherical_kernel_3<CGAL::Cartesian&lt;CGAL::Gmpq>,
CGAL::Algebraic_kernel_for_spheres_2_3<CGAL::Gmpq> > >::Sphere_3&)’


Could it be cgal's version, I have standard build for ubuntu 10.04, its
version 3.9-1, I think ....

Could it also be that I am not linking to the proper libs? now I am linking
to the following to compile any CGAL code

target_link_libraries(learning_by_demonstration /usr/lib/libCGAL.so)          
                                                                         
target_link_libraries(learning_by_demonstration /usr/lib/libCGAL_Core.so)
target_link_libraries(learning_by_demonstration
/usr/lib/x86_64-linux-gnu/libmpfr.so.4)
target_link_libraries(learning_by_demonstration
/usr/lib/x86_64-linux-gnu/libgmp.so.10)

are any missing?

Thanks 

Miguel
