Programming :: Include Boost In Eclipse Project?

I'm using Eclipse to build a small c++ program using boost.

Code:

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

[code]....

I can right click on boost::regex and it takes me to the header file regex_fwd.hpp, but when I go to build it, it gives me the error:

Code:

DescriptionResourcePathLocationType
/usr/include/boost/regex/v4/basic_regex.hpp undefined reference to `boost::basic_regex<char, boost::regex_traits<char, boost::cpp_regex_traits<char> >

[code]...
