Dear all,

I am trying to install GNUradio 3.7.3 on Ubuntu 14.04. I did everything  
necessary to install GNUradio such as: dependencies, required libraries  
…  
Even when I run “make test”, it turns out to be passed 100% (no error  
reported), but when I finally run “sudo gnuradio-companion” on terminal,  
it  
turns out a message like this: “sudo: gnuradio-: command not found”  
I don’t know why, but I think I did not successfully install GNUradio  
3.7.3  
Can anyone help me with this?

Thank you very much  
Van-Ly

Hi Van-Ly,

“sudo: gnuradio-: command not found”

this sounds like you have a space between “-” and “companion”.

Greetings,
