My friend has installed GNU Radio from this link  
[http://blogs.bu.edu/mhirsch/2012/07/installing-gnu-radio-in-ubuntu-12-04-x64/comment-page-1/](http://blogs.bu.edu/mhirsch/2012/07/installing-gnu-radio-in-ubuntu-12-04-x64/comment-page-1/)  
Then when running GNURadio , she found UHD blocks in it .

1- Does this mean that this link has installed GNURadio & UHD on Ubuntu  
,  
and that there is no need to install UHD ?  
2- Is there any command that she can run in terminal to check if UHD is  
installed?

Thanks ! 🙂

Hi Sara,

although that guide is correct (it just uses the popular and  
well-working build-gnuradio script), I’m always a little surprised  
where people find information. For later reference: The official GNU  
Radio website is [http://gnuradio.org/](http://gnuradio.org/) and the official installation  
instructions can be found under  
[http://gnuradio.org/redmine/projects/gnuradio/wiki/InstallingGR](http://gnuradio.org/redmine/projects/gnuradio/wiki/InstallingGR) . Your  
friend did a source build, which is nice, because she now has the most  
current version of GNU Radio 🙂 .

UHD comes with a lot of tools, starting with uhd\_. So typing uhd\_ and  
then should show you a lot of programs, for example  
uhd\_find\_devices .

To find out if UHD is actually working in GNU Radio, just open the  
gnuradio-companion, use the search tool (magnifier logo) and search  
for uhd.

Greetings,  
Marcus
