I mean : how do you compile your application? Do you use a makefile provided 
by CGAL of cgal_create_makefile?

Different compiler, actually. Ubuntu 7.10 uses g++-4.1.2, which is usually

Joachim Reichel

 They have not been updated since the 
release of Ubuntu 7.10. However, gmp packages have been update very recently
