Sylvain:

Attached is a short C++ file which when compiled with the attached makefile produces the error messages found in the attached log.txt file.  --  I am using g++ version 4.2.3.

Thank you for your help.

For some weeks now I have been using CGAL in a C++ program that I
have been compiling with Visual C++.  Today I tried to compile it
on a computer running Ubuntu (8.04) which comes with CGAL 3.3.1-2
already installed, and I got these error messages:

    /usr/include/CGAL/Straight_2.h:268:          error: orientation is not a member of CGAL::CGALi
 
    /usr/include/CGAL/squared_distance_2_1.h:577:          error: parallel is not a member of CGAL::CGALi

Any help will be appreciated.

Probably a missing header, or wrong order.
Can you please sens a small program that reproduces this?
