[filesystem 1.34] no matching function for call to 'is_separator' ...
When trying to compile this (tester.cpp): #include <boost/filesystem/path.hpp> int main(int argc, char *argv[]) { boost::filesystem::path path1( "some/path" ); boost::filesystem::path path2; path2.append( path1.begin(), path1.end() ); } like this:

I get similar errors when building with g++ 3.3. Any ideas?
Well, it seems I've answered my own question. The similarity of the interface to std::basic_string led me to believe that what I was attempting was possible. But the fundamental difference is that basic_string _is_ a container of characters (the type returned when its iterators are dereferenced), but basic_path only _pretends to be_ a container of path elements (strings) which is what is returned when its iterators are dereferenced. Might I humbly suggest something along the lines of the following? template<class String, class Traits> basic_path<String, Traits> & basic_path<String, Traits>::append( iterator first, iterator last ) { assert( first.m_path_ptr == last.m_path_ptr ); m_path.append( first.m_path_ptr->m_path.begin() + first.m_pos, last.m_path_ptr->m_path.begin() + last.m_pos ); return *this; } Declared in the class thus: class iterator; basic_path & append( iterator first, iterator last );
