该程序展示了创建一个简单的gnome的GUI窗口以及对其编译的过程

/* hellwrld.c by [e-mail]
 *
 * The very basics on how to create a GUI in gnome.
 * Basically creates a label with hello world caption
 * and attaches a function to the delete_event signal.
 *
 * To compile this you will need to include all of the
 * required libs which is alot.  Gnome makes the process
 * easier by having gnome-config that lists the needed 
 * libraries
 *
 * Example Makefile:
 * --------------------------------------------
 * CC=gcc
 * CFLAGS := -Wall $(shell gnome-config --cflags gnomeui)
 * LINK := $(CC) $(shell gnome-config --libs gnomeui)
 * all: hellwrld
 * hellwrld: hellwrld.o
 *    $(LINK) -o $@ $<
 * hellwrld.o: hellwrld.c
 *    $(CC) $(CFLAGS) -c -o $@ $<
 * --------------------------------------------
