I built the gr-osmosdr using the cmake instructions:
git clone git://git.osmocom.org/gr-osmosdr
<http://git.osmocom.org/gr-osmosdr>
cd gr-osmosdr/
mkdir build
cd build/
cmake ../
make
sudo make install
sudo ldconfig
I built Gnuradio and all its gr folders using sudo apt-get install
gnuradio. As for having the UHD compiled into my gr-osmosdr, can you
shine light on how I can go about doing this?
Thanks,
Jose

I updated osmosdr to the latest version

but I still get the same issue.
Any ideas?

You don't appear to have UHD compiled-in to your gr-osmosdr, so
that's one problem.
How did you build GR + friends?
There are two ways to "best" install GR + friends from source. Other
methods cannot guarantee that everything is rigorously up-to-date,
and installing from pre-packaged binaries will almost always cause
you grief if you use other peoples code that's "modern".
See:
http://gnuradio.org/redmine/projects/gnuradio/wiki/InstallingGRFromSource
But if you want to stick with packaged binaries, then you need to
install uhd from packaged binaries as well *before* building gr-osmosdr,
otherwise, UHD support won't be compiled in to gr-osmosdr--there's no
away around that.
