Re: [Discuss-gnuradio] Experience with Ubuntu 15.04 and Gnuradio 3.7.8

Hello John: Ubuntu 15.04 uses the new GCC 5. I haven't yet tried building UHD and GNU Radio with it myself, but maybe there are issues?? Otherwise, I think you should be fine. --Neel On 17 August 2015 at 11:11, John Petrich wrote: > All, > > I am considering updating to Ubuntu 15.04 from 14.

Marcus, So everyone is thinking it:  Show a little discuss-gnuradio love and set up an educational one time group buy.  I have had SDR envy for some time; stuck with RTL/Hermes/Funcube, when what I really need is some new Ettus hardware.  It NEVER shows up on Ebay it seems. Think how many less

Hello, I've been searching a lot about SDR and USRP devices to purchase. All I need is a board with a receiver port (transmitter is not important for now) and it's necessary to be compatible with Gnuradio. There are some options, but I don't have experiency or enough knowledge to choose one of the

Marcus, Below $120 is okay for me. Actually, the features are not important for me now, because I just want to simulate a Cognitive Radio without a lot of details. I just wanna see it working to study and learn about this process. Like I said, it's important to have a receiver port and be compatib

Hi Pedro, You will, as for any device, need to figure out what you need, specification-wise. I'm obviously a bit biased, but no one else might even be able to help you unless you wrote some numbers: frequencies you're interested in, bandwidth you want to sample at once, stability, available int

Hi all! Thank you for contributing to gnuradio and providing new users like me with help. I have read and worked through some of the guided tutorials. However I come to a point now where it seems that own Python code has to be written. Unfortunately I am more like a C++ guy and would appreciat

Hi David, I think we can all agree that the community starting to run at the mention of Matlab is not a good thing - I think there might be frustration behind this flight instinct, so let's try to make this a success story. I concur with the pretty detailed reply from mathworks; the reason is lik

??Thanks Nathan, Marcus - would you agree? I am not sure I totally understand what that entails, and I certainly am not clear how to go about doing it!! Does it mean that GNU Radio would use it's "preferred" Boost via static linking leaving MATLAB to use a different version - how would this
