CGAL users discussion list

[Martin Weier <>]

Hi,

I am trying to use the apollonius graph for one of my projects.  
Currently I am developing on osx
and xcode. I started by installing CGAL-3.5. For this i installed all  
dependencies using macports.
Now CGAL compiles with no errors (I am using gcc 4.0.1 from which I  
heard has some troubles with
compiler optimizations and CGAL).
However, when I try to compile something with xcode, I get the  
following linker error:

"CGAL::Random::Random()", referenced from:

Does anybody have any ideas on what goes wrong and how to fix it. Am I  
missing some linker options? By the way the apollonious graph
examples compile fine. Can anybody help me to set up a working xcode  
project? I would appreciate your help.
