Hi,
I have known that the .cc example in gnuradio would be compiled when
running "make" in the build directory.But how can I compile my own .cc
file through g++ command line?
Thanks.

What version of GNU Radio are you using? Message ports with Python blocks
are supported as of 3.6.4:
class message_consumer(gr.sync_block):
def __init__(self):
gr.sync_block.__init__(
self,
name = "message consumer",
in_sig = None,

I find the example at the online page
http://gnuradio.org/doc/doxygen/page_pfb.html very helpful (code at the end
of the page). It runs and generates nice plots. Still trying to get used to
it.
But the code at gr-filter/python/pfb.py does not run. It appears to be a
module? How do I run it or use

Ah, sorry, I misunderstood your question. Yes, the GRC block
pfb_channelizer_ccf is equivalent to the block in
gr-filter/python/pfb.py, and, in fact, will use this block in the
generated python.

Is it equivalent to use the pfb_channelizer_ccf block in the GRC though?
Does the GRC approach suffer reduced capability vs. the python approach?

No, there's no way to produce a GRC file from a python file.

Thanks I found it as in gr-filter/examples/python/pfb.py. I also found
something in gnuradio-core/src/examples/pfb directory.
Have to excuse my ignorance here since I haven't really worked that much
with python approach. Have mostly stayed in GRC flow graph and used the
generator to get the python
Thanks for letting us know the documentation is out of date.
You should find filterbank examples in gr-filter/examples.

Hi Patrick,
my mistake, the correct is 'wxgui', as you said.
This solved my problem. Yesterday I cloned and compiled the gnuradio sources
by myself, instead of using the script provided by in the official site. I
notice that the script doesn't compile the master branch. The script did a
checkout
I'm not sure but shouldn't the category be [wxgui] and not [wxwidgets]
in ~/.gnuradio/config.conf?
see in your gnuradio/gr-wxgui directory the readme's

avg-alpha, example
$ uhd_fft --fft-rate=10 --avg-alpha=0.3 etc
Increase the fft
Hi Marcus,
double checked this, gnuradio from repository is not installed.
I notifice that when I click the close button in the uhd_fft window, for an
instant the FFT plot is shown.
Thanks.

I recompiled all again last night. Build version 3.6.4.1-203-g0641a449. The
problem continues.
The suggestion with the '[wxwidgets] style=nongl' didn't work for me.
OpenGL is working fine here. All 3D desktop effects works and glxgear runs
fine.
Any clue about this problem ?

I just pushed an update to MacPorts' gnuradio-devel and gnuradio-next. I doubt
it changes the behavior you're talking about, but you never know. When I try
to execute that GRC file in either devel or next, I get "QWidget: Must

Hi list,
I tried to use message ports with python blocks but I can't find
something like "register_msg_port_in" or similar. And asking google
didn't give me any results as well. So I can't register a message port.
This rises the question if it is possible to use message ports with
python blocks.

There's tutorials on the web site.
But you don't actually build blocks with GRC (unless they're
hierarchical blocks), you use them.

I got it, just need the destructor to be public.
