I’m having trouble when trying to run a GRC flowchart with the No GUI
option. The thing is that even with the simplest flowchart I get the
following error: can only concatenate list (not “str”) to list. I’ve
tried all the different configurations in the Options block but I get
always the same result.
I’m using GNU Radio Companion v22.214.171.124-154-g7ee2f91d in a machine
running Ubuntu Precise 64 bits (Linux kernel 3.13.0-55-generic).
Find attached the .grc file I am using and a screenshot of what I get
when I run it.
Can anybody give me some insight on this?
Thank you very much in advance!
