Re: [Discuss-gnuradio] Companion flow error

[Nate Temple]

Hi Nikos,

You need the baudline binary which is here [1]. It will unpack to the folder 
baudline_1.08_linux_x86_64/. Put the contents in the folder 
baudline_1.08_linux_x86_64/ in your home directory. You should then be able to 
call the command "baudline" and if that works, the GR sink block should work. 

[1] - http://www.baudline.com/baudline_1.08_linux_x86_64.tar.gz
