How do I compile Gtk applications?

[twistor96]

Hi,

I want to start learning GTK however when I tried to compile the sample application on http://library.gnome.org/devel/gtk-tutorial/stable/c39.html I get
Package gtk+-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gtk+-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gtk+-2.0' found

I compiled it with

gcc HelloWorld.c -o base `pkg-config --cflags --libs gtk+-2.0`


I guess I haven't got the gtk development files installed or something, but I can't find them anywhere in synaptic.


(Using ubuntu 9.04)

Take a look for the package libgtk2.0-dev, that should do it.
