For gnuradio 3.8 you need to use gr3.8 branch and for gnuradio 3.9 you need to use the master branch. > Using, eg. gr-osmosdr.so.0.2.0 and gnuradio-3.8.4.0, which I have compiled > successfully > File "/usr/lib64/python3.9/site-packages/osmosdr/osmosdr_swig.py", line 13, > in <module> > from . import _osmosdr_swig > ImportError: /usr/lib64/libgnuradio-osmosdr.so.0.2.0: undefined symbol: > _ZN2gr12msg_accepter4postEN5boost13intrusive_ptrIN3pmt8pmt_baseEEES5_ > > c++filt translates that symbol to > gr::msg_accepter::post(boost::intrusive_ptr<pmt::pmt_base>, > boost::intrusive_ptr<pmt::pmt_base>) gr::msg_accepter::post() function is implemented in libgnuradio-runtime.so, so first check that it is there by executing the following commands (provide the full output) find /usr/ -name "libgnuradio-runtime.so*" ldd -r /usr/lib64/libgnuradio-osmosdr.so.0.2.0 ldd -r /usr/lib64/libgnuradio-runtime.so objdump -T /usr/lib64/libgnuradio-runtime.so | grep _ZN2gr12msg_accepter4postEN5boost13intrusive_ptrIN3pmt8pmt_baseEEES5_ objdump -T /usr/lib64/libgnuradio-runtime.so | grep msg_accepter | grep post objdump -TC /usr/lib64/libgnuradio-runtime.so | grep msg_accepter | grep post and then try a clean rebuild with your current gnuradio and boost versions. Go in the gr-osmosdr source directory, delete the build directory and start from scratch. P.S. Also make sure that you don't have multiple gnuradio versions installed at the same time in /usr/ and /usr/local/ Regards, Vasil
