 4 int
 5 main (int   argc,
 6       char *argv[])
 7 {
 8   const gchar *nano_str;
 9   guint major, minor, micro, nano;
10 
11   gst_init (&argc, &argv);
12 
13   gst_version (&major, &minor, &micro, &nano);
14 
15   if (nano == 1)
16     nano_str = "(CVS)";
17   else if (nano == 2)
18     nano_str = "(Prerelease)";
19   else
20     nano_str = "";
21 
22   printf ("This program is linked against GStreamer %d.%d.%d %s
",
23           major, minor, micro, nano_str);
24 
25   printf("macro version: %d.%d.%d
", GST_VERSION_MAJOR, GST_VERSION_MINOR, GST_VERSION_MICRO);
26   return 0;
27 }
