title: Qt create and QLabel, why is there an error?
body: <p>I'm using <code>Qt creator 2.0.1</code>, and when entering this line:</p>
  
  <p><code>#include &lt;QLabel&gt;</code></p>
  
  <p>I get the following error:</p>
  
  <p><code>QLabel: No such file or directory</code></p>
  
  <p>Why is that? And, how can I include a label in this case?</p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>@maverik showed me how to solve the <code>QLabel</code> error, but I'm now getting this error:</p>
  
  <p><img src="https://i.stack.imgur.com/I00QK.png" alt="enter image description here"></p>
  
  <p>The program I'm trying to run is:</p>
  
  <pre><code>#include &lt;QtCore/QCoreApplication&gt;
  #include &lt;QtGui/QLabel&gt;
  
  int main(int argc, char *argv[]) {
  QCoreApplication myapp(argc, argv);
  QLabel *label = new QLabel("Hello");
  label-&gt;show();
  return myapp.exec(); 
  }
  </code></pre>
  
  <p>Any ideas?</p>
  
  <p>Thanks.</p>
