Hi all,

I can’t get the usrp\_sink and usrp\_source blocks to show up in gnu  
radio. I followed the instructions here:

[http://code.ettus.com/redmine/ettus/projects/uhd/wiki/UHD\_Linux](http://code.ettus.com/redmine/ettus/projects/uhd/wiki/UHD_Linux)

I installed the Master/Unstable version. It completed without an error  
but when I open gnu radio I don’t see the blocks.

Can someone help me out?

Thanks,  
Rich
