Newbie query: Boilerplate code created by gst-element-maker does not compile

[Krzysztof Konopko]

Have you tried it with GStreamer-1.0? There might be some subtle
differences as the guide is updated to conform to GStreamer-1.0.

It worked for me with GStreamer-1.0 without a hitch (just make sure you
use "myfilter" consistently (rather than "my_filter").
