title: How to solve mingw32-make.exe exited with code 2 error?
body: <p>I've installed <code>Qt Open source 4.8.3</code> library for Windows on <code>Windows 8 Pro x64</code>, <code>Qt Creator 2.6.0</code> and <code>MingW 4.4.0</code> manually. From Qt Creator I've setup kits and compilers. I opened the analog clock example comes along with Qt Creator and rebuild the project. The following error are emitted by the compiler.</p>

  <p>I've verified that <strong>C:/Qt/4.8.3/examples/widgets/analogclock/analogclock.cpp</strong> exists. Besides, this project comes with Qt installation and I didn't change anything.</p>
  
  <p>Why is this error occurring and how can i fix it?</p>
