[Boost-users] [Regex] Link error with G++ 3.3.2, but Okay with 3.4.5

Hi all,

I have the following code to validate a given url using boost::regex. The
code is failing linking with g++ 3.3.2, but is building with 3.4.5

Any workaround, or pointer to help to build in 3.3.2? I am on boost 1.32.
All the linking errors are related to std strings.

#include <iostream>
#include <string>
#include <boost/regex.hpp>  // Boost.Regex lib

using namespace std;

int main( )
{
        std::string url("http://myserver:80/index.html");
        boost::regex re;

        try
        {
                boost::regex
re("(ftp|http|https):\/\/(\w+\.)*(\w*)\/([\w\d]+\/{0,1})+");
                if (!boost::regex_match(url, re))
                {
                        throw "Your URL is not formatted correctly!";
                }
        }
        catch (...)
        {
                cerr << "The regexp " << re << " is invalid!" << endl;
        }
}

g++ regex2_url.cpp /usr/lib/libboost_regex.a
