title: In function `__static_initialization_and_destruction_0(int, int)'
body: <p>hi I was compiling my program using <strong>make</strong> command previously because my program includes multiple header files. Since I added <strong>BOOST LIBRARIES</strong> I'm not able to compile with the same command and getting the following error.</p>
  
  <pre><code>In function `__static_initialization_and_destruction_0(int, int)':

  <p>I searched the link :<a href="https://stackoverflow.com/questions/6847105/g-compile-error">g++ compile error</a> but it was not helpful.
  Can someone please point me to the right link or even a small help will be appreciated.</p>
