Boost thread error: undefined reference

Question

#include <boost/thread/thread.hpp>
#include <iostream>

void hello()
{
  std::cout <<
    "Hello world, I'm a thread!"
    << std::endl;
}

int main(int argc, char* argv[])
{
  boost::thread thrd(&hello);
  thrd.join();
  return 0;
}

I ran tried to compile this program, and got these errors:

/usr/include/boost/thread/pthread/mutex.hpp:40: undefined reference to
   `boost::thread_resource_error::thread_resource_error()'
/usr/include/boost/thread/pthread/mutex.hpp:40: undefined reference to

Can any one tell me why i am getting this error?
