Hi all, I have installed GNURadio and UHD together using the build-script on a Ubuntu 12.04 machine. After I run the GRC, it does not show me any sources menu where I can find USRP\_source or USRP\_sink. My guess is that gr-uhd is not enabled in my install. Is there a way to enable gr-uhd ? I tried the ./configure --enable-gr-uhd given on some webpage but there is no configure script in my gnuradio folder. Rest of GRC is working fine. Thanks for your help. Best Regards, Hemant ---
