Re: [Discuss-gnuradio] Porting cgran AIS to the new cmake build system

Hi Chris, Might I be so bold to suggest that in your efforts, you consider using the gr-osmosdr abstraction (http://sdr.osmocom.org/trac/wiki/GrOsmoSDR) so that the RTL-SDR could be used too. In fact it supports UHD, FCD and RTL-SDR, and works well in gqrx for example. Sorry for being cheeky :P

Take a look at gr-air-modes for details on how I did it there. gr-osmosdr follows the UHD API for the most part, so a lot of it drops in pretty easily. I'm not going to pull in a patch which makes the receiver depend on gr-osmosdr, but I'm happy to have a command-line option (or even autodetect)
