<para>
To compile a GLib application, you need to tell the compiler where to 
find the GLib header files and libraries. This is done with the
<application>pkg-config</application> utility.
</para>
<para>
The following interactive shell session demonstrates how
<application>pkg-config</application> is used:
<programlisting>
$ pkg-config --cflags glib-2.0
 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include 
$ pkg-config --libs glib-2.0
 -L/usr/lib -lm -lglib-1.3  
</programlisting>
</para>
<para>
If your application uses modules, threads or <structname>GObject</structname>
features, it must be compiled and linked with the options returned by the 
following <application>pkg-config</application> invokations: 
<programlisting>
$ pkg-config --cflags --libs gmodule-2.0 
$ pkg-config --cflags --libs gthread-2.0
$ pkg-config --cflags --libs gobject-2.0
</programlisting>
</para>
<para>
The simplest way to compile a program is to use the "backticks"
feature of the shell. If you enclose a command in backticks
(<emphasis>not single quotes</emphasis>), then its output will be
substituted into the command line before execution. So to compile 
a GLib Hello, World, you would type the following:
<programlisting>
$ cc `pkg-config --cflags --libs glib-2.0` hello.c -o hello
</programlisting>
</para>
