Hi, In boost/filesystem/path.hpp there are a set of methods controlled by: # ifndef BOOST_FILESYSTEM_NO_DEPRECATED public: typedef bool (*name_check)( const std::string & name ); basic_path( const string_type & str, name_check ) { operator/=( str ); } basic_path( const typename string_type::value_type * s, name_check ) { operator/=( s );} string_type native_file_string() const { return file_string(); } string_type native_directory_string() const { return directory_string(); } static bool default_name_check_writable() { return false; } static void default_name_check( name_check ) {} static name_check default_name_check() { return 0; } basic_path & canonize(); basic_path & normalize(); # endif I have been using normalize for several releases of boost, but I am very concerned that it is no longer part of the officially supported spec and may disappear in some future release. normalize is a very very useful routine and one of the reasons for using boost was to let smarter people produce routines that could become standards. Our local version of 'normalize' did a poor job and I went to boost to fix this version hopefully once and for all. So if it is going away, what are my options?
