Re: [Discuss-gnuradio] Problem installing new module

Hi all,

The same error I am also getting for the basic gr-howto-write-a-block-3.2

======================================================================

So I think its more of configuration issue specific to my machine (MAC OS 10.5). GNURadio works perfectly. Only when I try to add new block, I get same error.. I am stuck.. Any help will be appreciated.

Thanks,
sagar

The runtime doesn't like a reference you are passing to a 'connect'
call.  Check what you are putting in the connect call that you are
wiring to 'sink_ff' input 0.  It should be a properly instantiated gr
block or hierarchical block.
