Hi,

I’ve installed the GNURadio & UHD correctly. However, I can’t use my  
USRP  
because I don’t have installed the UHD module in my tree of modules of  
the  
Gnuradio 3.6.5.1

But I can see in the path of the file system where GNUR is installed the  
folder named gr-uhd where are all the files related to all the block of  
this modules (usrp\_sink usrp\_source )

Could you give me some help ?

Thanks!

Regards,

_Fernando L. Rodríguez Brizuela -_

When you run cmake, it’ll tell you why or why not it disables  
components. Maybe you just don’t have UHD installed?

Did you follow the correct install order? UHD must be installed before  
GNU  
Radio. If you didn’t, uninstall both of them and then start with UHD.
