title: Error while loading shared library: libconfig++.so.9
body: <p>While I compile the code in Makefile, I've put LINKPATH = -L/usr/local/lib in the g++ line. And of course "libconfig++.so.9" is under /usr/local/lib</p>
  
  <p>But when I execute the executable file, it still says cannot find libconfig++.so.9.</p>
  
  <p>Anyone knows why?? Appreciate any help.</p>
