Hi,

I'm having a problem running usrp_p25_rx.py. I've never done anything with op25 before. I followed the build instructions on the wiki at op25.osmocom.org/wiki. I had the same issue that I saw a couple other people post about with adding an include of stddef.h to op25.cc. After that everything built as far as I can tell. 

I'm using ubuntu 12.04 x64 and gnuradio 3.6

If anyone has any idea what to look at it would be appreciated.
thanks,


When I try to run usrp_p25_rx.py I get the following error:
