title: installing QT4.7.4 for embedded Linux. Multiple errors
body: <p>I'm an <strong><em>absolute beginner</em></strong> with Linux and developing for embedded Linux. I'm trying to install QT for embedded Linux onto my Fedora 15 laptop to target an i.Mx233.</p>
  
  <p>Firstly, within the qt-everywhere-opensource-src-4.7.4 folder, I enter the command:</p>

  </code></pre>
  
  <p>With the linux-arm-imx qmake conf file:</p>

  <p>The install was obviously unsuccessful but I'm not sure why the .cpp files are failing. </p>
  
  <p>As I said, I'm a beginner with Linux and have no available support here. I realise helping a newbie can be very tedious but I'm lost with this and any help would be greatly appreciated.</p>
  
  <p>EDIT: It should probably be said that I've tried QT, Freescale etc. directly with no luck. No one?</p>
