About importerror in gnuradio 3.7.0

GNU Radio
1

Dear list,

I want to move my out of tree model from gnuradio 3.6.5 to 3.7.0. I
follow the introduction about how to move from 3.6 to 3.7. The code is
able to build. However when I running the python script, still meet the
importerror as follow:

ImportError: /usr/local/lib/libgnuradio-gmsktr.so: undefined symbol:
_ZN2gr6filter24mmse_fir_interpolator_ffC1Ev

I have tried two days to find the bug but no progress…does somebody
have experience about this problem? Any suggestions would be
appreciated!

Best regards

Alex

Also, check out the page explaining the differences between 3.6 and
3.7 to help you relocate where things are:
