How to compile your GLib application
</p></div><div class="refsect1" lang="en"><a name="id2970416"></a><h2>Compiling GLib Applications on UNIX</h2><p>
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
<span class="application">pkg-config</span> utility.
</p><p>
The following interactive shell session demonstrates how
<span class="application">pkg-config</span> is used:
</p><pre class="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
</pre><p>
</p><p>
If your application uses modules, threads or <span class="structname">GObject</span>
features, it must be compiled and linked with the options returned by the
following <span class="application">pkg-config</span> invokations:
</p><pre class="programlisting">
$ pkg-config --cflags --libs gmodule-2.0
$ pkg-config --cflags --libs gthread-2.0
$ pkg-config --cflags --libs gobject-2.0
</pre><p>
</p><p>
The simplest way to compile a program is to use the "backticks"
feature of the shell. If you enclose a command in backticks
(<span class="emphasis"><em>not single quotes</em></span>), then its output will be
substituted into the command line before execution. So to compile
a GLib Hello, World, you would type the following:
</p><pre class="programlisting">
$ cc `pkg-config --cflags --libs glib-2.0` hello.c -o hello
</pre><p>
