Hi,
thank you for your reply.
Where I have to set the compiler option -std=c99 you suggest?
thanks again


Hi,

I'm running on Mac OS X 10.6.5 Intel Core 2 Duo (64-bit) and I'm compiling
with g++ 4.2.1. Boost has been downloaded following the link provided in
the CGAL installation manual and the version is 1.40.0.
I'm also attaching the hw_rounding.hpp lines.
Thanks


#ifndef BOOST_NUMERIC_INTERVAL_HW_ROUNDING_HPP
#define BOOST_NUMERIC_INTERVAL_HW_ROUNDING_HPP
#include <boost/numeric/interval/rounding.hpp>
#include <boost/numeric/interval/rounded_arith.hpp>

#define BOOST_NUMERIC_INTERVAL_NO_HARDWARE

// define appropriate specialization of rounding_control for built-in types
#if defined(__x86_64__) && defined(__USE_ISOC99)
#  include <boost/numeric/interval/detail/c99_rounding_control.hpp>

looking at the conditions of this include it seems that __USE_ISOC99 is not
defined. Can you try the compiler option -std=c99 ?

Any suggestions?
Thank you in advance!

it would be nice if you would include some important information, like which
linux distribution you are using, 32 or 64bit, compiler and version, Boost
version. And please attach the first ~45 lines of
/usr/local/include/boost/numeric/interval/hw_rounding.hpp.
