title: Unable to build a example gtk+ program
body: <p>I am trying to built some sample gtk+ examples that came with the gtk+ sources. My need was only to have a gtk+ UI to a C program. I went about downloading and building gtk+ but realised (through SO) that this was not needed and that I only need libgtk-3-dev.</p>
  
  <pre><code>sudo apt-get install libgtk-3-dev
  Reading package lists... Done
  Building dependency tree       
  Reading state information... Done
  libgtk-3-dev is already the newest version.
  0 upgraded, 0 newly installed, 0 to remove and 373 not upgraded.
  </code></pre>
  
  <p>EDIT: NOTE: Issue is not with the sequence of libraries or includes as I am using the makefile that came with gtk+. </p>
  
  <p>I tried compiling an example that I had with the gtk+ code I downloaded. I get the below errors. The other queries on this topic mentioned that the order of the flags matter, but in this case I have used the makefile that came with the sources. Should I be installing something more than the libgtk-3-dev library (running on Ubuntu 14.04 ).</p>
