[nhs_0702]

i read lib boost in http://www.boost.org/doc/libs/1_42_0.../file_size.cpp then build on QTCreator but it error,can you help Me debug source ?




#include <boost/filesystem/operations.hpp>
#include <iostream>
namespace fs = boost::filesystem;
int main( int argc, char* argv[] )
{
if ( argc != 2 )
{
std::cout << "Usage: file_size path\n";
return 1;
}
std::cout << "sizeof(intmax_t) is " << sizeof(boost::intmax_t) << '\n';
fs::path p( argv[1], fs::native );

if ( !fs::exists( p ) )
{
std::cout << "not found: " << argv[1] << std::endl;
return 1;
}
if ( !fs::is_regular( p ) )
{
std::cout << "not a regular file: " << argv[1] << std::endl;
return 1;
}
std::cout << "size of " << argv[1] << " is " << fs::file_size( p )
<< std::endl;
return 0;
}

Did you link your application against boost library?

my source http://www.mediafire.com/?inzzmlwwm4w
i link source into boost source (not binary),can you help me ?

[wysota]

Obviously you didn't link the body of the method your compiler complains about.
