title: How to install gtk on OSX for use with g++/gcc compiler
body: <p>I already asked this question <a href="https://apple.stackexchange.com/posts/111239/edit">at apple.stackexchange.com</a>, but I was told it was the wrong place for this question - so I will ask it here, as I was suggested to do.</p>
  
  <p>At my university we got the task to implement a c-program which has a GTK-GUI. The GTK-GUI is already implemented, we just have to implement a algorithm which hands it some data.</p>
  
  <p>I already got gcc/g++ working. But when i try to compile the project the compiler returns the error, that it does not find the gtk:</p>
  
  <pre><code>fatal error: 'gtk/gtk.h' file not found
  #include &lt;gtk/gtk.h&gt;
           ^
  </code></pre>
  
  <p><strong>So my question is:</strong>
  How do I install gtk on OSX Mavericks for using it with gcc/g++ compiler?</p>
  
  <p>My setup: MacBook Pro Retina Mid 2012 with OSX Mavericks. Homebrew is installed and working if it could be useful for the installation.</p>
  
  <p>(Of course the Apple Command Line Developer Tools are installed)</p>
