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 File "/usr/local/lib/python3/dist-packages/osmosdr/__init__.py", line 21, in <module> from .osmosdr_python import * ImportError: generic_type: type "sink" referenced unknown base type "gr::hier_block2" What is the problem here?

I was wrong, I installed main-3.9 only! OK. > I guess the problem would be something to do with the cmake prefix path I have passed: 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.

[PATCH] fix osmocom_fft for current main-3.9 gnuradio
by Stefan `Sec` Zehl 16 Oct '21

16 Oct '21

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. >From 645240939b50dc6f4cebd277c6a690a919f67fb5 Mon Sep 17 00:00:00 2001 From: Stefan `Sec` Zehl <sec(a)42.org> Date: Sun, 10 Oct 2021 14:31:23 +0200 Subject: [PATCH 1/3] follow pyqwidget rename in gnuradio 86b5fb30182c69ec38490346a4269d1ffce9ffb4 --- apps/osmocom_fft | 25 ++++++++++++++++++++----- 1 file changed, 20 insertions(+), 5 deletions(-) diff --git a/apps/osmocom_fft b/apps/osmocom_fft index b23124a96f..6e072f8c6c 100755 --- a/apps/osmocom_fft +++ b/apps/osmocom_fft @@ -242,7 +242,10 @@ class app_top_block(gr.top_block, Qt.QMainWindow): from gnuradio import fosphor self.scope = fosphor.qt_sink_c() self.scope.set_frequency_range(0, input_rate) - self.scope_win = sip.wrapinstance(self.scope.pyqwidget(), Qt.QWidget) + if hasattr(self.scope,'pyqwidget'): + self.scope_win = sip.wrapinstance(self.scope.pyqwidget(), Qt.QWidget) + else: + self.scope_win = sip.wrapinstance(self.scope.qwidget(), Qt.QWidget) self.scope_win.setMinimumSize(800, 300) elif options.waterfall: self.scope = qtgui.waterfall_sink_c( @@ -256,7 +259,10 @@ class app_top_block(gr.top_block, Qt.QMainWindow): self.scope.enable_grid(False) self.scope.enable_axis_labels(True) self.scope.set_intensity_range(-100, 20) - self.scope_win = sip.wrapinstance(self.scope.pyqwidget(), Qt.QWidget) + if hasattr(self.scope,'pyqwidget'): + self.scope_win = sip.wrapinstance(self.scope.pyqwidget(), Qt.QWidget) + else: + self.scope_win = sip.wrapinstance(self.scope.qwidget(), Qt.QWidget) self.scope_win.setMinimumSize(800, 420) elif options.oscilloscope: @@ -266,7 +272,10 @@ class app_top_block(gr.top_block, Qt.QMainWindow): name="", nconnections=1 ) - self.scope_win = sip.wrapinstance(self.scope.pyqwidget(), Qt.QWidget) + if hasattr(self.scope,'pyqwidget'): + self.scope_win = sip.wrapinstance(self.scope.pyqwidget(), Qt.QWidget) + else: + self.scope_win = sip.wrapinstance(self.scope.qwidget(), Qt.QWidget) self.scope_win.setMinimumSize(800, 600) elif options.qtgui: @@ -281,7 +290,10 @@ class app_top_block(gr.top_block, Qt.QMainWindow): plottime=True, plotconst=True ) - self.scope_win = sip.wrapinstance(self.scope.pyqwidget(), Qt.QWidget) + if hasattr(self.scope,'pyqwidget'): + self.scope_win = sip.wrapinstance(self.scope.pyqwidget(), Qt.QWidget) + else: + self.scope_win = sip.wrapinstance(self.scope.qwidget(), Qt.QWidget) self.scope.set_update_time(1.0/10) self.scope_win.setMinimumSize(800, 600) @@ -294,7 +306,10 @@ class app_top_block(gr.top_block, Qt.QMainWindow): name="", nconnections=1 ) - self.scope_win = sip.wrapinstance(self.scope.pyqwidget(), Qt.QWidget) + if hasattr(self.scope,'pyqwidget'): + self.scope_win = sip.wrapinstance(self.scope.pyqwidget(), Qt.QWidget) + else: + self.scope_win = sip.wrapinstance(self.scope.qwidget(), Qt.QWidget) self.scope.disable_legend() self.scope_win.setMinimumSize(800, 420) -- 2.30.2 CU, Sec -- Cooking without animal products is like doing sysadmin work without vi.

[PATCH] rudimentary sigmf support for recordings
by Stefan `Sec` Zehl 10 Oct '21

10 Oct '21

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()?
