Subject: [PATCH] fix osmocom_fft for current main-3.9 gnuradio
Message-ID: <20211010124825.GB35313@ice.42.org>

Hi,

The commit 86b5fb30182c69ec38490346a4269d1ffce9ffb4 in gnuradio broke
osmocom_fft due to removing/renaming the pyqwidget wrapper.

This patch tries to fix that in a backwards-compatible manner.

Yes this was changed by https://github.com/gnuradio/gnuradio/pull/4994. We
did not know that function was being used externally.

Message-ID: <20211010155357.GC35313@ice.42.org>

While playing with osmocom_fft, i found two additional issues:

- the '-S' option fails due to a RuntimeError being changed to a ValueError
- the '-Q' option fails due to a missing "parent" parameter.

the first patch should be backwards-compatible.
The second one i've only tested with gnuradio v3.9.3.0 / maint-3.9

Subject: [PATCH] rudimentary sigmf support for recordings
Message-ID: <20211010160512.GD35313@ice.42.org>

Hi,

This is a starter patch to produce a .sigmf-meta file for each
recording. It contains the minimum useful info that is usually coded
into the filename.

I'm not sure if anyone thinks this is worthwhile. There is a lot more
that could be recorded in the .sigmf-meta file like e.g. current gain
values, current bandwidth or antenna settings (if available), but i
wanted to see if there is any interest for this at all.

It would maybe also nice to add the actual sdr device name that was
used, but as far as I can see there is no way in python to query which
device/driver is used by a specific osmosdr.source()?

A bureaucracy is like a computer program.  Usually, the question is
how to arrange it so that what you want is composed of operations that
the bureaucracy supports.  In addition, in any bureaucracy, there is
always *someone* whose job is to approve violations of the rules.

We'll fix the pyqwidget() regression in GNU Radio, and I'm going to put out
another v3.9 release soon to address this. So, no need to fix on this end.
Do you think the second set of patches relates to something that changed
during 3.9? Those look like they might be 3.8 vs 3.9. Was osmocom_fft
previously working under 3.9?

I'm pretty sure it worked back when I ported osmocom_fft to 3.9 in Feb
of 2020. I have no idea when it started breaking as I don't use the -S /
-Q optiones usually.

How did you install gnuradio - from source or from the ppa repository? And how did you install gr-fcdproplus?

One possible reason is two incompatible gnuradio versions installed on your system in different locations - `/usr/` and `/usr/local/`. Make sure to remove all other gnuradio versions and that there is no `/usr/include/gnuradio` directory. Then delete the build directory and start from scratch.

Another possible reason is the version of gr-fcdproplus that you have installed is not compatible with your gnuradio version.

You can try removing gr-fcdproplus as it is not needed for RTL-SDR devices.

Hi Vasil,

1. How did you install gnuradio - from source or from the ppa repository? And how did you install gr-fcdproplus?
	> /usr/local/include/gnuradio/hier_block2.h:93:35: note:   no known conversion for argument 1 from 'gr::fcdproplus::fcdproplus::sptr' {aka 	'boost::shared_ptr<gr::fcdproplus::fcdproplus>'} to 'gr::basic_block_sptr' {aka 'std::shared_ptr<gr::basic_block>'}
	>    93 |     void connect(basic_block_sptr src, int src_port, basic_block_sptr dst, int dst_port);

	Since I needed a specific version of gnuradio, I built it from source and I didn't remember installing gr-fcdproplus seperately, it was all packaged together I guess! But anyhow it was found 	to be installed in my system.

2. One possible reason is two incompatible gnuradio versions installed on your system in different locations - `/usr/` and `/usr/local/`. Make sure to remove all other gnuradio versions and that there is no `/usr/include/gnuradio` directory. Then delete the build directory and start from scratch.

	I removed the previous installations and built the new gnuradio from source (master branch) as you mentioned. But still the same error shows up.
	I also tried installing via sudo apt install gr-osmosdr, but still dind't get it in GRC Menu successfully!

3. Another possible reason is the version of gr-fcdproplus that you have installed is not compatible with your gnuradio version.
	 > I just need the RTL-SDR component

	You can try removing gr-fcdproplus as it is not needed for RTL-SDR devices.
	Seems like it is needed, when I remove it throws error earlier during any OOT module's make installation!

Is there any simple way where I can get both RTL-SDR and USRP blocks in GNUradio? Any advice would be much appreciated!

The error you are getting now is pretty different. AFAIK gr-osmosdr (from mater) still does not supports gnuradio 3.10 (from master)

You should not install gr-* packages from the repository as they are built for a different gnuradio version. You need to install them from source. Remove all gnuradio and gr-* packages that you've installed.

After uninstalling gr-fcdproplus you need to delete gr-osmosdr's build directory and start from scratch by running `cmake ..`

Hello Vasil,

Sorry! I was wrong, I installed main-3.9 only!

thangz at thangz-VirtualBox:~/Desktop/gr-osmosdr/build$ gnuradio-companion --log info
<<< Welcome to GNU Radio Companion 3.9.3.0 >>>

Block paths:
	/usr/local/share/gnuradio/grc/blocks

Loading: "/home/thangz/Desktop/gnuradio/rtlsdr_fm_spectrum_simple.grc"

I guess the problem would be something to do with the cmake prefix path I have passed:

thangz at thangz-VirtualBox:~/Desktop/gr-osmosdr/build$ cmake -DCMAKE_INSTALL_PREFIX=/usr ../

thangz at thangz-VirtualBox:~/Desktop/rtl-sdr/build$ cmake -DCMAKE_INSTALL_PREFIX=/usr ../


I also used the same prefix for gnuradio installation!

Regards,
Thangaraj

OK.

I doubt that it is related to the prefix. Have you tried deleting gr-osmosdr's build directory and starting from scratch (after remvoing gr-fcdproplus package)? Alternatively you can delete only the CMakeCache file.

What is the exact problem that you have right now? Provide the full cmake and make output.

Hello Vasil,

The problem was with gr-fcdproplus package only! After removing it was installing fine and I got it under GRC Menu!

But there is a new error while executing the flowgraph!

Console:

Generating: '/home/thangz/Desktop/gnuradio/rtlsdr_fm_spectrum_simple.py'

Executing: /usr/bin/python3 -u /home/thangz/Desktop/gnuradio/rtlsdr_fm_spectrum_simple.py

Traceback (most recent call last):
  File "/usr/local/lib/python3/dist-packages/osmosdr/__init__.py", line 17, in <module>
    from .osmosdr_python import *
ImportError: generic_type: type "sink" referenced unknown base type "gr::hier_block2"

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/home/thangz/Desktop/gnuradio/rtlsdr_fm_spectrum_simple.py", line 37, in <module>
    import osmosdr

    from .osmosdr_python import *
ImportError: generic_type: type "sink" referenced unknown base type "gr::hier_block2"


What is the problem here?

Regards,
Thangaraj

Cool.

In your previous mails you've said that you're setting cmake's prefix to `/usr` but here osmosdr is in `/usr/local` (the default prefix). Make sure you have only one gr-osmosdr installed on your system. My advice is to remove all gr-osmosdr installations (from source or from package), make sure that there are not `osmosdr` files in `/usr/` and `/usr/local`, and then reinstall gr-osmosdr.

I'm not familiar with this error. It looks like

Hello Vasil,

As you said I have removed and reinstalled 'gr-osmosdr' (with prefix '/usr')!

Verified if there are two installation of gr-osmosdr:

thangz at thangz-VirtualBox:/usr/lib/python3/dist-packages/osmosdr$ ls
__init__.py             osmocom_siggen_base.pyc
__init__.pyc            osmocom_siggen_base.pyo
__init__.pyo            osmosdr_python.cpython-38-x86_64-linux-gnu.so
osmocom_siggen_base.py

thangz at thangz-VirtualBox:/usr/local/lib/python3/dist-packages$ ls          #osmosdr folder under '/usr/local/'!
gnuradio  pmt  volk_modtool


Console:

Generating: '/home/thangz/Desktop/gnuradio/rtlsdr_fm_spectrum_simple.py'

Executing: /usr/bin/python3 -u /home/thangz/Desktop/gnuradio/rtlsdr_fm_spectrum_simple.py

During handling of the above exception, another exception occurred:

    from .osmosdr_python import *
ImportError: generic_type: type "sink" referenced unknown base type "gr::hier_block2"

I am looking into the links you sent, thank you :)
