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](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](http://files.ettus.com/binaries/uhd_unstable/repo/uhd/ubuntu/%60lsb_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 1. 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? v/r, Rich ---

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. Tom ---

I resolved this issue. The problem was there was an older version of gnu radio installed on this laptop that wasn’t being removed properly. When I realized that and made sure to get it all off, the next time I ran the ettus website install commands it worked. The only issue I’m having right now is that it seems my network setup overwrites the static ip address I assign to my laptop from time to time, leading to me not being able to ping the USRP. I’m not sure of a good workaround for this. Thanks, Rich On Tue, Aug 5, 2014 at 11:02 AM, Martin B. [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) ---

You can use ifconfig to change the current IP address, but Network Manager will come along and clobber that unless it’s told not to. I should point out that, long-term, you’re better to learn some basic sys admin stuff outside of this forum, because it will be very helpful not just with Gnu Radio, but with anything else you might want to do with your computer, and discuss-gnuradio just isn’t the place to be getting that knowledge. – Marcus L.

Yeah thanks. I consider this topic closed. Appreciate the responses. Rich
