Error undefined Symbol

Hello,

I am trying to do a block similar to AsyncCRC32, but with some changes. User, When I make a copy of the code into a personal block, I encounter the following problem that I am unable to resolve. The error is:

Traceback (most recent call last):

  File "/home/minidani/GNUradio/qpsk_software_2.py", line 14, in <module>

    from gnuradio import DaniBlock

  File "/usr/local/lib/python3.10/dist-packages/gnuradio/DaniBlock/__init__.py", line 18, in <module>

    from .DaniBlock_python import *

ImportError: /usr/local/lib/libgnuradio-DaniBlock.so.1.0.0: undefined symbol: _ZN2gr7digital3crc7computeEPKhm

Could u be able to give me a solution?

Thank you.
