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

[Atish Nazir]

You can drop files into the plugin directory and they'll be picked up.  On
my Xubuntu for example:

/usr/lib/x86_64-linux-gnu/gstreamer-0.10/

However IMHO using environment variable GST_PLUGIN_PATH to override the
search path is a better thing to do during development.
