Hi,
i’m trying to create my first hier block following these rules:
http://gnuradio.org/redmine/projects/gnuradio/wiki/GNURadioCompanion#Hierarchical-Blocks
but when i’m going to generate the flow graph, i get the error message:
Generate Error: All strings must be XML compatible: Unicode or ASCII, no
NULL bytes or control characters
I also tried a very simple graph like pad
source(float)->throttle(float)->pad sink(float) but i face the same
problem.
throttle rate’s value is the value of a parameter i set as sample_rate.
Any advice?
thx

Is there more verbose to go with that error?
Can you attach a minimal example that causes the problem?

Can you try using an all ASCII path for the grc file? I think the XML
parser may be having trouble w/ the characters in the file path.

Yes, the problem was the greek words in the path!
Thank you very much!
