Re: 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.

The work has not been merged into the official gnuradio master branch.

Its on the gr_basic branch on git://gnuradio.org/jblum.git
