Hi there
Could you please run a quick test for us and report back the results - ideally please
paste the entire response starting from entering the python command
So the test is
- from the command prompt issue the "python" command with no args
- you should receive some messages and then a ">>>" prompt
- enter this command :
from gnuradio import op25
- then enter this one :
dir(op25)
Here's an example of what I'm looking for

Either you have been a very long-time user, or perhaps you've gotten svn to cough up

You'll need to uninstall and do an install using the current version.
Also Perhaps Stevie has some insight as to how this state of affairs might have come
about, not sure...

i used the osmocom buildinstructions "svn
co http://op25.osmocom.org/svn/trunk op25". how should i get the latest?

Thank you so much Max! it is now executing without dying. all the weird errors i was
getting are GONE. now i can focus on sniffing some signals!
Thanks ALOT,

disconcerting to see this error again but by disabling the 'FFT Sink", i can get
rid of that error. the scope plot runs but i have no sound. there is some output in
terminal:

first: any idea as to how i can get some sound? what should i be looking for in the
scope?
second: i have a strong desire to get rid of the "AttributeError:
'gr_hier_block2_sptr' object has no attribute 'set_callback'" without
disabling the fft sinks! how is that i was not getting this error with the fft sinks
enabled after uninstalling and reinstalling OP25 but after turning the computer off and
restarting the error is back?
third: what is this "memory leak" message?
thanks.

That's because the op25.i isn't declaring any destructors. The minimum fix
is to change that for our code but what's really required is to update our
for GNURadio 3.6 and that means switching to a cmake build, renaming code,
splitting impl/interface, dropping obsolete interfaces and making use of
new features. If we go that far then there's a heap of other stuff to do. I
am about to write another email about that.

Will it still decode with this "memory leak"?
I need a baseband P25 sample file to test and get familiar with the scopes. I am unsure of
my ezcap tv tuner and i am unsure of capturing a signal with the discriminator tap (i dont
even know what kind of file i should save it as!). I really need a sample that is known to
be good so that i can learn what it looks like on the scopes.
for the record id like to say that setting .gnuradio/config.conf to:
[wxgui]
style=gl
(instead of 'style=nongl') has killed the 'set callback' and
'swig_pmt.i' attribute errors. Balint brought the opengl issue to my attention.
the 'fsk4_slicer_fb' attribute error was fixed by reinstalling op25; apparently
somehow i had a very old version of op25 that didnt have the slicer. Max exposed this
weirdness by looking at:

Thanks everybody!
Matt
please if anyone has a good sample of baseband P25 please share a file or two with me.
