Excuse me,
I'm trying to use  the  library  boost/filesystem.
I wrote:

#include "boost/filesystem/operations.hpp"
#include "boost/filesystem/path.hpp"
#include <iostream>

or

#include "boost/filesystem.hpp"
#include <iostream>
 
but in both cases  this error occurs:

LINK : fatal error LNK1104: cannot open file 'libboost_filesystem-vc90-mt-gd-1_35.lib'

How can I solve this problem?
Thanks and best  regards.
