To compile these platform demos you will need a C compiler, for example gcc. You will also need GTK+ 3 including headers and pkg-config files. Linux distributions usually abstract GTK+ 3 headers and pkg-config files into separate packages called gtk3-devel, gtk3-dev or similar.
Beyond the prerequisites mentioned above, several tools has been developed to assist you further in developing your GNOME application. GNOME also recommends a specific coding style and conventions which this section will elaborate further upon.
DevHelp: An API documentation browser for GNOME.
A GNOME IDE (Integrated Development Environment). An IDE can assist you in writing and debugging C code, for example Builder or Anjuta.
Glade: A user interface designer for GTK+ Applications.
An IRC Client, for example Polari or Empathy. If you run into problems while following the beginner tutorials, join #gnome on irc.gnome.org.
Most applications in the GNOME project is written in the GNU style of indentation. The tutorials and code examples presented are following this convention and you are recommended to do so too.
To run the code samples:
Copy and paste the code into filename.c
In the terminal type:
