Okay. Tried this, then deleted the xml file before attempting to make again without it. Got the following error when re-making (the line with the xml file had a destination which I had thought was just for that file) What do I need to do to fix this? Thanks, - John CMake Error at grc/CMakeLists.t

This sounds like exactly the use case for stream tags ( http://gnuradio.org/redmine/projects/gnuradio/wiki/BlocksCodingGuide#Stream-Tags). More info on how to use them is here: http://gnuradio.org/doc/doxygen/page_stream_tags.html Unfortunately there isn't a good listing of tag naming conventions,
