Hello,

I am trying to work with grc flow graphs. I downloaded the latest  
versions  
of gnuradio yesterday and I used Marcus’s script to do it. I have not  
connected my laptop with USRP daughterboards. I am just trying to see if  
gnuradio companion was installed properly or not. I have ubuntu 11.10.

When I run the the dial\_tone.grc program in gnuradio-examples/grc/audio  
folder, it gives me the following error:

./dial\_tone.grc: line 1: syntax error near unexpected token `newline' ./dial_tone.grc: line 1:`\<?xml version='1.0' encoding='ASCII'?\>’

When I open a new terminal and type gnuradio-companion, a new GUI window  
comes up. However, the window only contains two blocks. When I click on  
the  
block group names (sources, sinks, etc.) in the right hand side, nothing  
shows up. I have attached a screen shot of the flow editor GUI with the  
email. Is it happening because the GRC requirements were not installed  
in  
my machine properly?

It’s probably a very basic question :S . Any feedback will be very  
appreciated.

Thanks,

Nazmul
