If you haven't already, try removing ~/.cache/grc_gnuradio/cache.json and
restarting GRC. Then do the reselect if it still shows as an error. One or
both of those should do it.

Has there been a release of GRC3.9 that fixes the errors in some of the
blocks that comes from the swig to pybind change? e.g. I have a flow
with the signal source, and it has this error:
Param - Waveform(waveform):
Expression gr_waveform_t.GR_COS_WAVE is invalid for type 'int'.

You'd have to have these installed before you build your gr-osmosdr from
source, otherwise
the gr-osmosdr can't use rtl-sdrs.
So, they must already be there :)

Hi Christophe and all,
It works now! I guess it's like you and Marcus said I might have a mix of
3.8 and 3.9. I installed the GNU Radio from the binary package before.
Today I removed it and reinstalled the GNU Radio from the source code
(maint-3.9 branch). Then the fm_rx/tx examples work as
Also, you may want to install the rtl software
apt install rtl-sdr librtlsdr
It's possible they may have been installed with gr-osmosdr.

Hi Ralf,
it's not about the version of gr-osmosdr – the gr-osmosdr you use just has to
be linked
against exactly the ABI version of the GNU Radio you intend to run :)
Debian, and thus Ubuntu, and thus Mint, do ship a gr-osmosdr, which is built
against their
build of GNU Radio; that's why linux
Hi Marcus,
to be precise: I use Linux Mint 20.1 which is based on Ubuntu.
Effectively, the gr-osmosdr module version 0.2.0-2 works with the
version of GNU Radio that is available by default in this Linux Mint
version (3.8.1-rc1-2build2) but as far as I remember, it did not work
with GNU Radio
I solved the bind python exception as follows:
1. The bind command cannot be used with a blank argument, or (I think) with
multiple arguments.
Running the command this way:
$gr_modtool bind

That's just a warning and can be safely ignored.

Hi Ralf,
glad to hear you've got it to work!
When not using the PPA (which I was assuming you'd be doing), you'd get the
exact
gr-osmosdr that works with Ubuntu's version of GNU Radio (i.e. 3.8.1.0 as I
thought you've
installed?).
Best regards,
Marcus

Hello Marcus,
I had done this before (installed from PPA) but I didn't get a module
that worked with GNU Radio 3.8.2. That's why I have compiled it from
source. When the module is compiled, you have to pay attention to the
correct prefix for cmake.

You have to do none of this,
sudo apt install gr-osmosdr
does everything. And then you're done and can use the OSMOSDR Source or the
RTL-Source
(which are essentially the same).
Cheers,
Marcus

Hello Alberto,
you may try this:
git clone git://github.com/osmocom/gr-osmosdr -b gr3.8
That's how I got the sources for GNU Radio 3.8 one or two weeks ago.

Ralf

Thank you very much!
I have installed gnuradio !

If you need to use gr-osmosdr and gr-iqbal, you need to install
gnuradio-3.8 because those packages do not support gnuardio-3.9 yet.
Version 3.9 is the "bleeding edge".
I've never used pybombs to install software - I just use git - but you
need to tell pybombs you want to install gnuradio
Hi
if fm_rx works with firdes.WIN_KAISER, it indicates that your
flowgraph use som GR3.8 codes. 3.9 should use window.WIN_KAISER
the output of python3 fm_rx3.py also clearly indicates that
the window class is not the same in your install and in
17 matches
