  <p>Additionally, I have tried to print my libz config using</p>
  
  <pre><code>ldconfig -v|grep libz
  </code></pre>
  
  <p>The result will be as follows:

  <p>I was wondering why this may happen. And I really need your guys help to solve this problem.</p>
  
  <p>What's more, my 'gdb' will throw this error too. When I use 'dmesg' command, I got the message as follows:
