ich habe versucht eine stl-list mit einem boost path zu kombinieren. der quellcode sieht wie folgt aus:
| C++: |
#include <list>
#include <string>
#include <iostream>
#include "boost\filesystem\operations.hpp"
namespace boostFS = boost::filesystem;
bool find_file( const boostFS::path& dir_path, const std::string& file_name, std::list<boostFS::path&> path_found )
{
if ( !exists( dir_path ) )
return false;
boostFS::directory_iterator end_itr;
for ( boostFS::directory_iterator itr( dir_path ); itr != end_itr; ++itr )
{
if ( is_directory( *itr ) )
{
if ( find_file( *itr, file_name, path_found ) )
return true;
}
else if ( itr->leaf() == file_name )
{
path_found.push_back(*itr);
return true;
}
}
return false;
}
int main( int argc, char *argv[] )
{
char fileTyp[] = "test.txt";
boostFS::path searchDir("./");
std::list <boostFS::path> pathsFound;
std::list <int>::size_type length;
find_file(searchDir, fileTyp, pathsFound);
length = pathsFound.size()
std::cout << "Path:" << std::endl;
for( int i = 0; i < (int)length; i++ )
{
std::cout << (pathsFound.front()).string() << std::endl;
pathsFound.pop_front();
}
}

leider bekomme ich vom compiler folgende fehlermeldung, mit der ich aber leider nichts anfangen kann. 
ich mußte die fehlermeldung am ende, da sie zu lang zum posten war
