Compiler error on Mac OS X 10.8 with Homebrew CGAL/Swig (follows on Issue 23)

[GoogleCodeExporter]

This issue follows on Issue 23 (which did help the compilation go further; 
thank you!)

Problem now with "Alpha_shape_2.h:594:27: error: use of undeclared identifier 
'locate'"

# What steps will reproduce the problem?
1. Installed CGAL 4.0.2 and swig 2.0.8 with Homebrew on OS X
2. git clone https://code.google.com/p/cgal-bindings/ (HEAD at 2ea2630) and cd 
cgal-bindings
3. cmake -DCGAL_DIR=/usr/local/Cellar/cgal/4.0.2/lib/CGAL/ -DBUILD_PYTHON=ON 
-DCGAL_CXX_FLAGS=-DCGAL_CFG_NO_CPP0X_VARIADIC_TEMPLATES
4. make

# What is the expected output? What do you see instead?

When running make:

• Merged into: #22

[GoogleCodeExporter]

This is probably a bug in CGAL.
Can you try replacing locate by this->locate.
If it's a bug, I'll fix it in CGAL directly.

Original comment by sloriot...@gmail.com on 2 Oct 2012 at 9:50

[GoogleCodeExporter]

Is the replacement locate to this->locate be done in the installed 
Triangulation_2.h file? Or do I re-build cgal? Modifying just the installed 
Triangulation_2.h, the result is:

and so on.

The fragment of Triangulation_2.h looks like:
  Face_handle
  this->locate(const Point & p,
         Locate_type & lt, int & li, 
         Face_handle start = Face_handle()) const
  {
    typedef Triangulation_structural_filtering_traits<Geom_traits> TSFT;
    typedef typename internal::Structural_filtering_selector_2< 
      TSFT::Use_structural_filtering_tag::value >::Tag Should_filter_tag;

    return generic_locate(p, lt, li, start, Should_filter_tag());
  }

  Face_handle
  this->locate(const Point & p, Face_handle start = Face_handle()) const
  {
    Locate_type lt;
    int li;
    return locate(p, lt, li, start);
  }

[GoogleCodeExporter]

No, in the file Alpha_shape_2.h line 594.

replace:
Face_handle pFace = locate(p, type, i);
by
Face_handle pFace = this->locate(p, type, i);

• Changed state: Duplicate

[GoogleCodeExporter]

I hit the same problem on Linux, and fixing Alpha_shape_2.h line 594 fixed it.
