I don't know about the first error, but the second error talks about RTTI. The dynamic_cast requires from the compiler to support RTTI. For you it means that you probable need to enable this compiler feature (probably by using some flag).

Hi all

 

I have a strange compiling error with Intel compiler 10.0.025 as follows:

 

===========================

1. C:\Program Files\CGAL-3.3\include\CGAL/double.h(245): error: the global scope has no "nextafter"
    return ::nextafter(d1,d2);

 

2. C:\Program Files\CGAL-3.3\include\CGAL/Object.h(91): error #259: run-time support for RTTI is disabled
          const Wrapper<T> *wp = dynamic_cast<const Wrapper<T> *>(Ptr());
                                                                  ^
          detected during instantiation of "bool CGAL::Object::assign(T &) const [with T=CGAL::Object::empty]" at line 109

===========================

 

I am trying to rebuild a pre-existing solution to make a new executable with Intel compiler.

When compiling the codes with MS compiler or Gcc, there was no problem.

 

Do I need to recompile the source codes of CGAL again?

 

Thank you.
