Hello all,

I'm having trouble getting the UHD USRP block category to show up in GRC. Can someone hep me through this issue. Here are the steps I've taken using Ubuntu 13.10:

1) Uninstalled gnuradio and uhd using the following command to start fresh:
sudo apt-get purge gnuradio gnuradio*  uhd uhd*

2) Followed the Ettus instructions here http://ettus-apps.sourcerepo.com/redmine/ettus/projects/uhd/wiki/GNURadio_Linux, specifically:
sudo bash -c 'echo "deb http://files.ettus.com/binaries/uhd_unstable/repo/uhd/ubuntu/`lsb_release -cs` `lsb_release -cs` main" > /etc/apt/sources.list.d/ettus.list'
sudo bash -c 'echo "deb http://files.ettus.com/binaries/uhd_unstable/repo/gnuradio/ubuntu/`lsb_release -cs` `lsb_release -cs` main" >> /etc/apt/sources.list.d/ettus.list'
sudo apt-get update
sudo apt-get install -t `lsb_release -cs` uhd gnuradio
3) Opened gnuradio and searched for usrp_sink and usrp_source. They do not exist.

Is there something I am clearly missing in this flow? I really appreciate any help someone can give me.

Note: I don't have a USRP to connect to my laptop right now. I'm assuming that shouldn't keep me from designing with the UHD_USRP blocks for future implementation, right?



When you say "search" I assume you mean using the find tool in GRC to look up the block name? What about just looking in the category tree for the "UHD" category?

What version of GNU Radio did that install? Looks like it should be 3.7.3. You can check with:
$ gnuradio-config-info -v

And double-check to make sure that UHD is installed. You should have a "uhd_find_devices" if it is. And you should also have the "uhd_fft" program installed with gr-uhd.
