Divide by zero would crash the block, and likely the whole flowgraph unless
the error is getting caught somewhere. There's probably a thread hanging
around until you manually kill the program, and then the error gets printed.
I took a really quick look at uhd_packet_rx and packet_rx and it sure lo

Try putting an extra None for parent parameter as the last arg in those
instantiations. Take a look at the flow graph generation for any of the qt
GUI widgets. For some reason pybind doesn’t like the last default param.

Hello Kevin,
Thanks, your link had useful information about the principles to consider
with a vector source.
Considering the following generic flowgraph : Vector Source > Repeat >

I have seen that most of the variables are related
Yes,
__PIC__ is required, and ENABLE_PYTHON, too.
With hardcoded include directories to add_include in
bindtool/core/generator.py I'm able to generate the bindings and build
the module.
But trying to run the blocks fails with typeError.
For instance

Thanks for pointing that out Jeff. The way the usrp_packet_rx example
works is with a multiply_const block just before the packet_rx (where the
corr_est block lives) that by default is multiply by zero. So wouldn't we
automatically get that /0?
Is divide by zero a common cause for flowgraphs to

Just as one has to do with getting a file from Github, you have to click
on the 'Raw' button before you copy the file with your text editor. Once
you do that, you will have the correct format.
For good measure, attached is the grc file.

There's nothing wrong with the flow graph Barry posted to pastbin. GNU
