Hi, It's because gnuradio cannot find your share file. Try to set environment variable of LD_LIBRARY_PATH and PYTHONPATH. For example, if you are installing gnuradio using default setting, you can setup the environment path in terminal as follow
export LD_LIBRARY_PATH=/usr/local/lib export PYTHONPATH=/usr/local/lib/<python version>/dist-packages or export PYTHONPATH=/usr/local/lib/<python version>/site-packages where <python version> depends on what python version is installed. Before you set the environment path, please check that libgnuradio-core-3.5.0rc0.so.0 is in /usr/local/lib and there are gnuradio folder inside the python path.
