the command to compile is gcc -o dest source.c `gtk-config --cflags --libs`

gtk-config is a little program designed to make it easier to compile with gtk, it tells the compiler where to find stuff. If you just type the command, you get something like:

[helmet BuffyRox helmet]$ gtk-config --cflags --libs
-I/usr/lib/glib/include -I/usr/X11R6/include
-L/usr/lib -L/usr/X11R6/lib -lgtk -lgdk -rdynamic -lgmodule -lglib -ldl -lXi -lXext -lX11 -lm

This would be pretty useless by itself, but it relies on backquotes to take the output of a command and put it in a command line. So, these two commands end up being the same:

gcc -o dest source.c `gtk-config --cflags --libs`
gcc -o dest source.c -I/usr/lib/glib/include -I/usr/X11R6/include -L/usr/lib -L/usr/X11R6/lib -lgtk -lgdk -rdynamic -lgmodule -lglib -ldl -lXi -lXext -lX11 -lm
