Hi List,

I am trying to install GNU radio in ubuntu 14.04 with the UHD version  
3.8.4. But when i am installing GNU radio, it is by default using older  
version of UHD and not UHD 3.8.4.

How can i install GNU radio on my system that uses UHD version 3.8.4. ?

Hi Siva,

the problem is that you most probably want to do

apt-get install gnuradio

, right?

Since programs only work with the library versions they were linked with  
at build time, Ubuntu must install Ubuntu’s old UHD version. That’s a  
bad thing – you now have 3.8.4 (possibly from our website or  
hand-built) conflicting with whatever Ubuntu brought. You _must_

sudo apt-get remove gnuradio uhd-host libuhd3

and reinstall UHD 3.8.4 afterwards.

Then, use pybombs to install GNU Radio from source:

git clone -r [GitHub - gnuradio/pybombs: PyBOMBS (Python Build Overlay Managed Bundle System) is the GNU Radio install management system for resolving dependencies and pulling in out-of-tree projects.](https://github.com/pybombs/pybombs.git) && cd pybombs &&  
./pybombs install gnuradio

Best regards,
