CGAL users discussion list

Hi, I used the cgal code in linux. In the cmake configuration, it's ok. When I make my own project the error jumped like this:

include/CGAL/boost/graph/helpers.h: In function ‘bool CGAL::is_border(typename boost::graph_traits<Graph>::halfedge_descriptor, const FaceGraph&)’:

/home/wangwenzhi/cgal/cgal-2-install/lib/cmake/CGAL/../../../include/CGAL/boost/graph/helpers.h:35:14: error: expected primary-_expression_ before ‘(’ token

  return face(hd,g) == boost::graph_traits<FaceGraph>::null_face();

include/CGAL/boost/graph/helpers.h: In function ‘bool CGAL::is_valid_halfedge_descriptor(typename boost::graph_traits<Graph>::halfedge_descriptor, const FaceGraph&)’:

  face_descriptor f = face(h,g);

include/CGAL/boost/graph/helpers.h:293:12: error: expected primary-_expression_ before ‘(’ token
    if(face(h,g) != f){

include/CGAL/boost/graph/helpers.h: In function ‘bool CGAL::is_valid_face_descriptor(typename boost::graph_traits<Graph>::face_descriptor, const FaceGraph&)’:

  if(face(h,g) != f){

include/CGAL/boost/graph/helpers.h: In function ‘bool CGAL::is_valid_halfedge_graph(const Graph&, bool)’:

/home/wangwenzhi/cgal/cgal-2-install/lib/cmake/CGAL/../../../include/CGAL/boost/graph/helpers.h:392:27: error: expected primary-_expression_ before ‘(’ token

    valid = (halfedge(edge(begin, g), g) == begin);

include/CGAL/boost/graph/helpers.h:621:18: error: expected primary-_expression_ before ‘(’ token
    valid = (face(i, g) == face(next(i, g), g));

include/CGAL/boost/graph/helpers.h:680:18: error: expected primary-_expression_ before ‘(’ token
    valid = (face(i, g) != face(opposite(i, g), g));

include/CGAL/boost/graph/Euler_operations.h:299:20: error: expected primary-_expression_ before ‘(’ token
  set_halfedge(face(hnew,g), hnew, g);

when I added the #include <CGAL/boost/graph/Dual.h> in the file CGAL/boost/graph/Euler_operations.h and the file CGAL/boost/graph/internal/helpers.h

only one kind of error like this "include/CGAL/boost/graph/Dual.h:108:17: error: ‘Edge_around_face_iterator’ in namespace ‘CGAL’ does not name a template type
  typedef CGAL::Edge_around_face_iterator<Primal>      out_edge_iterator;  

include/CGAL/boost/graph/Dual.h:109:17: error: ‘Opposite_edge_around_face_iterator’ in namespace ‘CGAL’ does not name a template type
  typedef CGAL::Opposite_edge_around_face_iterator<Primal> in_edge_iterator;" occured. I am confused about the error like this. I found the iterator.h was included in the file Dual.h.

And I really don't know why.

It seemed some header not found, but when i tried to fix it, i found the including relationship very complicted. Could you give me some advices on how to fix the make error?

By the way, I used the CGAL version was 5.5, and I also tried the installed library from the newest source code in Github.The error remained the same. GMP-6.2.1, mpfr-4.1.0. GMP and mpfr used the source code to compile the libraries. Boost version was 1.80.
