I built the gr-osmosdr using the cmake instructions:

    git clone git://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

Hello,

I installed and tried to run the simple_ra_receiver flowgraph using a USRP N210 and was shown the following error message:

I updated osmosdr to the latest version from https://github.com/osmocom/gr-osmosdr

but I still get the same issue.

Any ideas?

Thanks,

Jose

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.
