CGAL users discussion list

[Apurv Verma <>]

@Anil: Did you find a way to use netbeans with CGAL, if yes please reply.

@Philipp: Where can one find this script, can you please write a simple hello world CGAL project with a CMakeLists.txt file.

Thanks Philipp I am using Netbeans IDE can you provide me some help to how to link CGAL library to it

Hi,
looks like you are not linking to the CGAL libraries correctly. Consult your IDE
documentation how to setup the linking process. CGAL also provides a
script to generate a basic CMakeLists.txt file for a small project which
in turn can generate a Makefile. Your IDE manual should have information
how to create a new project from existing sources using a Makefile.
