title: Qt Creator needs a compiler set up to build. Configure a compiler in kit options
body: <p>I just installed Qt 5.2 package on ubuntu. I simply created a Qt widget application, and when I tried to build it, I got the following message:</p>
  
  <blockquote>
    <p>Qt Creator needs a compiler set up to build. Configure a compiler in
    kit options</p>
  </blockquote>
  
  <p>I have tried several things, all of which were unsuccessful. I tried setting the compiler kit to </p>
  
  <blockquote>
    <p>Desktop Qt 5.2.0 GCC 32bit (default)
    <img src="https://i.stack.imgur.com/zEU7Y.png" alt="enter image description here"></p>
  </blockquote>
  
  <p>However it didn't work</p>
  
  <p>After that I set the compiler to </p>
  
  <blockquote>
    <p>GCC (x86 32bit in use/bin)
    <img src="https://i.stack.imgur.com/A9Onv.png" alt="enter image description here"></p>
  </blockquote>
  
  <p>However that didn't work either.</p>
  
  <p>I also tried adding gcc manually and gave it the path </p>
  
  <blockquote>
    <p>/usr/bin/g++-4.6</p>
  </blockquote>
  
  <p>but it still didn't work.</p>
  
  <p>This is what appears in there Qt Version tab</p>

  <p>This is what I get when I remove the .pro.user file and restart the IDE, Whats the difference between configuring a project as Desktop and Desktop Qt 5.2.0 GCC 32bit?
