[Boost-users] Installed boost::regex, and it compiles, but can't get it to link

Subject: [Boost-users] Installed boost::regex, and it compiles, but can't get it to link

I am running ubuntu 9.04

I have built the libs from 1.39.0 with gcc 4.3
and moved them to /usr/local/boost

I have done a $ sudo ldconfig -v and have seen the boost libaries are installed

here is the code, taken from the boost web site:

#include <boost/regex.hpp>
#include <iostream>
#include <string>

using namespace std;

int main()
{
    string line;
    boost::regex pat( "^Subject: (Re: |Aw: )*(.*)" );

    while (cin)
    {
        getline(cin, line);
        boost::smatch matches;
        if (boost::regex_match(line, matches, pat))
            cout << matches[2] << endl;
    }
}

I can compile ok: g++ -I /usr/local/boost/include/boost-1_39 -c
regex_example.cpp

But when I try to link I get a ton of errors, can anyone tell me what I need
to do next? -- Jerry

$ g++ -I /usr/local/boost/include/boost-1_39
-L /usr/local/boost/lib regex_example.cpp
