Question

when I try to compile this code:

#include <boost/filesystem/path.hpp>
#include <boost/filesystem/fstream.hpp>

using namespace std;

int main()
{
    boost::filesystem3::path file_path("C:\\Users\\Art\\Desktop\\ASO.sln");
    boost::filesystem3::path new_path(file_path.begin(),file_path.end() - 1);
    return 0;
} 

I’m getting an error:

C:\Users\Me\boost_path\..\..\..\boost_148\include\boost-1_48\boost\filesystem\v3\path.hpp:163: error: no matching function for call to 'convert(const boost::filesystem3::path*, const boost::filesystem3::path*, boost::filesystem3::path::string_type&, const codecvt_type&)'

Why? I assume there is a bug in boost::filesystem.

Answer 1

The begin() and end() iterators of boost::filesystem::path are not character iterators. They are directory iterators; they iterate over the directories in a path. The value_type of these iterators are paths themselves, which contain the directory.

So you can’t construct a path from another path‘s iterators like that.
