[Noel Warren <>]

I am trying to do something slightly out of the ordinary: I want to compile a Ruby C extension that uses some CGAL algorithms.  When I #include<CGAL/create_straight_skeleton_2.h> compilation fails and I get a long backtrace that I will append to the bottom of this email.

The failing sample can be found here.  Building ruby c extensions is done by running an extconf script that generates a make file.  I have attatched my makefile in case it is of use.

There is obviously something "big" I'm doing wrong but I can't see what it is from the output.  Any help will be greatly appreciated.
