c/g++ and boost parsing reg exp
 

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 <boost/regex.hpp>
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';
}

Thanks your help a lot in advance, Eric
on g++ 4.5.2 and linux kernel 2.6.35-25 of Ubuntu10.04 based

I only saw one question in your post; thus I guess the answer you are looking for is "Sponge Bob".


Seriously, try compiling/linking your code with something like:

Thanks
