Hello Vasil,
Thank you for your help. Editing python/__init__.py did solve my current
problem: After changing the exception handling to the following I was able to
move on to other issues while porting.
try:
# this might fail if the module is python-only
from .myModule_python import *
except ImportError:
dirname, filename = os.path.split(os.path.abspath(__file__))
__path__.append(os.path.join(dirname, "bindings"))
from . myModule _python import *
except ModuleNotFoundError:
dirname, filename = os.path.split(os.path.abspath(__file__))
__path__.append(os.path.join(dirname, "bindings"))
from . myModule_python import *
Re-installing my module gave me this cmake error:
CMake Error at lib/CMakeLists.txt … Target “gnuradio-myModule”
links to: gnuradio::gnuradio-fec but the target was not found.
I was able to solve this by removing the gnuradio:: qualifier from gnuradio-fec
and gnuradio-analog. For some reason, only gnuradio-fec but not
gnuradio::gnuradio-fec is known. Could this be an unintended bug? Under Gnu
Radio 3.8.5 gnuradio::gnuradio-fec was able to be found.
But right now I’m struggling with a new problem that I’m unable to solve:
Calling import myModule_python in gr-myModule/build/python/myModule/bindings/
throws a segmentation fault which gets traced back to
/usr/local/lib/python3.10/dist-packages/gnuradio/gr/__init__.py
The line responsible for the segfault is:
log.set_level(prefs().get_string("LOG", "log_level", "notset"))
Context for the line:
log = gr.logger("log")
log.set_level(prefs().get_string("LOG", "log_level", "notset"))
log_debug = gr.logger("log_debug")
Again I would be very thankful if someone could help me.
Thank you and regards,
Luca
