title: How to setup a C development environment on Linux for GTK+?
body: <p>I'm new to programming C in Linux. I like to make GUIs with GTKlibs. The only problem is that im unable - and not only with gtk - to install these packages correctly. I have problem to include the librarys like <code>#include&lt;gtk/gtk.h&gt;</code> if I have installed it with <code>sudo apt-get install gtklib-3-dev</code>.</p>
  
  <p>On compile time it sais everytime that the file is missing and so on. I have read the option to put dpkg configs and cflags to the compiler, but that doesn`t work either. How linux is managing the include folder and why do libs like gtk have an upperfolder with the version on it like gtk3 etc.. This is the problem that leads to missing files.</p>
