I created an out-of-tree module for my personal project.
In one block, I need to perform FFT and IFFF, so I put “#include
<gnuradio/fft/fft.h>” in the header file, and then declare
In the .cc file, I wrote d_ifft = new fft::fft_complex(64, false,
Then I can compile without any error messages, but when I run a flow
to test the block, it turns out an error message like this:
Traceback (most recent call last):
File “/home/van-ly/sandbox/gnuradio-builds/Test/top_block.py”, line
line 45, in
from PNC4TWRN_swig import *
line 28, in
_PNC4TWRN_swig = swig_import_helper()
line 24, in swig_import_helper
_mod = imp.load_module(’_PNC4TWRN_swig’, fp, pathname, description)
ImportError: /opt/gnuradio-3.7.3/lib/libgnuradio-PNC4TWRN.so: undefined
Could any one please help me with this?
Does any one know how to use the perform FFT in an out-of-tree module?
Thank you in advance,
