CGAL users discussion list

[Chansophea Chuon <>]

Dear Joachim:

Thanks for response. I am using pre-compiled version of CGAL
CGAL-devel-3.2.1-19.fc5
CGAL-3.2.1-19.fc5
CGAL-demos-source-3.2.1-19.fc5
running on Fedora Core 5 (Kernel 2.6.18-1.2257.fc5) with g++ (GCC) 4.1.1 20060525 (Red Hat 4.1.1-1).

I tried to compile again with the command (g++ -o test rs_example.C -I/usr/include -L/usr/lib -lCGAL
) and it showed this messages:

/usr/include/gmpxx.h: In destructor  ‘__gmp_alloc_cstring::~__gmp_alloc_cstring()’:
/usr/include/gmpxx.h:2096: error: ‘__gmp_free_func’ was not declared in this scope

I could not even use CGAL makefile.

Best regards,

Sophea
