Re: [Discuss-gnuradio] new stream selector block in gr-basic

Hi, 

This is great work.

I updated my Gnu Radio to the latest code using Marcus build-gnuradio script but I did not get this new selector block.

Can someone please explain me how can I integrate this new selector block into my gnuradio/GRC installation on Ubuntu.  Thanks,  Khalid.
