[Boost-users] cann't compile Regular Expressions to Split a String code

 Dear Boost programers:  I copied a piece simple Using Regular Expressions to Split a String  code from book(c++ cookbook) chapter 4 section 24, page 196-197, Example code 4.33  ---------------------------------------------------------------------  // Example 4-33. Using Boost's regular expressions  #include <iostream>  #include <string>  #include  int main() {  std::string s= "who,lives:in-a,pineapple under the sea?";  boost::regex re(",|:|-|\\s+"); // Create the reg exp  boost::sregex_token_iterator // Create an iterator using a  p(s.begin(), s.end(), re, -1); // sequence and that reg exp  boost::sregex_token_iterator end; // Crate an end_of_reg_exp  // marker  while (p != end)  std::cout << *p++ << '\n';  }  ------------------------  source code  http://examples.oreilly.com/9780596007614/
