i have added '#include "boost/algorithm/string/finder.hpp"' but it still does not solve my error.
A missing parenthesis is missing there. Instead of iterator_range<string_split> r1( make_split_iterator(s1, token_finder(is_any_of("/")), string_split()); you should write: iterator_range<string_split> r1( make_split_iterator(s1, token_finder(is_any_of("/"))), string_split()); parenthesis is missing just after token_finder.
