Sorry for the dummy question, but I didn’t find a simple and direct
answer searching around for this. (Not need to say also that I am just
starting with GNU Radio…
OK I have a code, generated with Gnu radio companion that i want to
run
over the command line to follow with GDB. I was under the impression
that
if I simply got the code generated in the ~/.grc_gnuradio, add the
def main():
“”" go, go, go “”"
top_block = CLASS
top_block.run()
if name == “main”:
print ‘Blocked waiting for GDB attach (pid = %d)’ % (os.getpid(),)
raw_input ('Press Enter to continue: ')
main()
Traceback (most recent call last):

line 53, in getattr

The code runs correctly on Gnuradio companion! No problem whatsoever!
Which would be the correct way to run the code auto-generated by
gnuradio
companion in a stand alone way?

Did you replace a class by [Class]? According to the Tutorial it
expects an object of type gr.top_block in this line.
if name == “main”: print ‘Blocked waiting for GDB attach
(pid = %d)’ % (os.getpid(),) raw_input ('Press Enter to continue:

it would run to attach GDB. However, i am getting the following error:
— Traceback (most recent call last): File “ieee802_15_4_phy.py”,

You try to call run on a ‘hier_block’. ‘run’ is a member of
‘gr.top_block’. top_block contains the scheduler and takes care of
correct initialization etc. So it is essentially the flowgraph.
I hope I could give you some hints on what might go wrong.

THANKS a lot!!! Yes you did really helped, as you said I was trying
to
run the wrong .py!!! The example generates two .py on on the main
directory, as you said, and another on the ~/.grc_gnuradio. I had seen
somewhere that gnuradio companion generate code on the ~/.grc_gnuradio.
I
looked, the code was there, I didn’t even think it could have also
generated other part of the code on the same directory of the .grc. It
was
naive, sorry.
I managed to run and connect gdb to it, using the PID. Now things will
become really interesting, i.e.e me fighting with gdb, and the
breakpoints,
to understand the values it passes through the code ;).
Thanks again Johannes, for taking your time to answer!
Best regards…
