Sure, I would use something similar:

gcc -o installer -Wall installer.c `pkg-config --cflags --libs dbus-glib-1`

Right, the code I put up on the FAQ was meant to be copied and pasted
into a program (a snippet), rather than compiled ready to run demo. If
you want a demo, just surround it with some main braces like this:

#include <dbus/dbus-glib.h>

 * main:
main (int argc, char *argv[])
        DBusGConnection *connection;
        DBusGProxy *proxy;
        GError *error = NULL;
        gboolean ret;

        connection = dbus_g_bus_get (DBUS_BUS_SESSION, NULL);
        proxy = dbus_g_proxy_new_for_name (connection,

        /* execute sync method */
        ret = dbus_g_proxy_call (proxy, "InstallPackageName", &error,
                                 G_TYPE_STRING, "openoffice-clipart",
                                 G_TYPE_INVALID, G_TYPE_INVALID);
        if (!ret) {
                g_warning ("failed: %s", error->message);
                g_error_free (error);
        return 0;

I'll make the FAQ clearer, and add the compile line. Apologies for the
