Re: Problem with using gr-filter in my OOT module

[Ron Economos]

Niko,

You have to add a couple of things to some CMake files.

1) Add the component(s) to the top level CMakeLists.txt. For example

https://github.com/drmpeg/gr-atsc3/blob/master/CMakeLists.txt#L77

2) Add the libraries to the linker in lib/CMakeLists.txt. For example:

https://github.com/drmpeg/gr-atsc3/blob/master/lib/CMakeLists.txt#L39

Dear Gnuradio community,

I'm having a problem with my OOT module which I like to use gr-filter.

Error looks like that.

File "/usr/local/lib/python3.10/site-packages/gnuradio/spektrumcsi/__init__.py", line 18, in <module>
    from .spektrumcsi_python import *
ImportError: /usr/local/lib/libgnuradio-spektrumcsi.so.1.0.0: undefined symbol: _ZN2gr6filter6kernel14fft_filter_cccC1EiRKSt6vectorISt7complexIfESaIS5_EEi

How can i attach fft_filter_ccc to my project?
In my ...impl.cc file exists:

#include <gnuradio/filter/firdes.h>

#include <gnuradio/filter/pfb_arb_resampler.h>

#include <gnuradio/io_signature.h>

#include <gnuradio/math.h>

#include <volk/volk.h>

and in impl.h i have

#include <gnuradio/filter/fft_filter.h>

Thank You in advance!
Niko
