Hi, I am writing a block that needs to call the gr::blocks::count_bits32() method in its corresponding CPP script. At the beginning of the script, I have added "#include <gnuradio/blocks/count_bits.h>".
When I used the "make" command to compile the program, no errors occurred. However, when I typed the "ctest -V" command in the terminal to check the compilation, the following error appeared: "ImportError: /home/<my-path>/build/lib/libgnuradio-<my-module’s-name>.so: undefined symbol: _ZN2gr6blocks12count_bits32Ej" Then, I typed the "c++filt _ZN2gr6blocks12count_bits32Ej" command in the terminal and obtained an output: "gr::blocks::count_bits32(unsigned int)". Do you have any idea why I encounter this error? Best wishes, Shumin Yao. Sent from Mail<https://go.microsoft.com/fwlink/?LinkId=550986> for Windows 10
