Hi,
    I'm trying to compile the following in Visual C++6.0 

#include "boost/config.hpp"
#include "boost/filesystem/operations.hpp" // includes boost/filesystem/path.hpp
#include "boost/filesystem/fstream.hpp"    // ditto
#include <iostream>                        // for std::cout
using namespace boost::filesystem;

int main(int argc, char* argv[])
{
 remove_all( "foobar" );
 create_directory( "foobar" );
 boost::filesystem::ofstream file( "foobar/cheeze" );
 file << "tastes good!\n";
 file.close();
 if ( !exists( "foobar/cheeze" ) )
   std::cout << "Something is rotten in foobar\n";

 return 0;
}

and I keep getting an error saying that

c:\program files\microsoft visual
studio\vc98\include\boost\filesystem\fstream.hpp(95) : error C2504:
'basic_ofstream<char,struct std::char_traits<char> >' : base class undefined
        C:\Program Files\Microsoft Visual
Studio\MyProjects\boost_filesystem\boost_filesystem.cpp(17) : see reference to
class template instantiation 'boost::filesystem::basic_ofstream<char,struct
std::char_traits<char> >' being compiled

which I think means that it can't find the implementation for
std::basic_ofstream<charT,traits> .
I'm not sure how to get around this because I can define a std::basic_ofstream,
without problem.

Thanks for help,
       Adam
