how to cross-compile and make gstreamer application codes in 2011Q2RRSDK

hi

i read examples in 2011Q2RRSDK.i am regretful to find no gst app in examples.there is a vala gst example in 2011Q2RRSDK.

i read RidgeRun 2011Q2 SDK Development and Integration Guide at https://www.ridgerun.com/developer/wiki/index.php/RidgeRun_2011Q2_SDK_Development_and_Integration_Guide

but i am not sure to be able to understand correctly and  apply it to build a gst app.

could anyone provide a gst app example in 2011Q2RRSDK  and way to build a gst app example?

thanks for any suggestion.I would like appreciate any help.
