I have install CGAL-3.2.1, OS is Linux.
In my CGAL application, i want to use Taucs to solve a sparse linear equation, and i include the header files like this:
//////////////////////////////////////////////////////////////////////////////////////
#include <CGAL/Exact_predicates_exact_constructions_kernel.h>
#include<CGAL/Taucs_solver_traits.h>
#include<CGAL/Taucs_fix.h>

#include<CGAL/Taucs_vector.h>
#include <CGAL/Delaunay_triangulation_3.h>
#include <CGAL/Triangulation_cell_base_with_info_3.h>

#include <CGAL/Triangulation_hierarchy_3.h>
#include <CGAL/circulator.h>
#include <CGAL/squared_distance_3.h>
#include <list>
//////////////////////////////////////////////////////////////////////////////////////////
but there are some compile errors occured, some of them is :

did i include the wrong header files ,or besides CGAL, do i need to install Taucs ?
