Re: Generator error flow graph

[Cinaed Simson]

That file will generate any error unless you have the input file 
"dummy.dat".

Try
   grep dummy.dat ./fm_rx.grc

which will return

   file: dummy.dat

or just open the file with GRC and replace file source with your front 
end hardware.

But you can run

  gnuradio/share/gnuradio/examples/analog/fmtest.py

without using the GRC.

P.S. - please keep the discussion on the mailing list. Thank you.

Hi Cinaed,

Sorry but I can’t attach my flow grap.

But for example, I have this error with fm_rx.grc available in 
gnuradio/gr-analog/examples.

Thanks for your help.

HI Fred - how about at least 1 example GRC which demonstrates the 
problem?

The  GRC file is a text file which you can attach to email.

    Hello all,

    I would like to known if someone has ever had this error when you
    want to generate python code with gnuradio :

    Generate Error: ‘catch_execptions’

    The problem is present with my personal flow graph and examples
    available with gnuradio.

    I’m using UHD 4.0 and gnuradio 3.8.

    Thanks for your help.

    Best regards.
