Hi, I'm not very experienced with c++ or with swig, so perhaps I'm missing something here, but I've got a problem and I can't figure it out.
I'm trying to replicate the signal_detector block in gr-inspector, and I can't seem to include the fft header so that swig detects it. I can't find the difference between my code and the gr-inspector code, either. I can reliably reproduce this by: 1. creating a new module. 2. creating a new block, with python qa code 3. including the fft header `#include <gnuradio/fft/fft.h>` 4. instantiating an fft_complex object `fft::fft_complex *d_fft = new fft::fft_complex(1024, true);` 5. running `make && ctest -V` The second test will fail, and the relevant part of the error message is "ImportError: /home/reader/code/drones/drone-hacker/gr-mwe/build/lib/libgnuradio-mwe-1.0.0git.so.0.0.0: undefined symbol: _ZN2gr3fft11fft_complexC1Eibi". Declaring the object without instantiating it - `fft::fft_complex *d_fft;` will work. Thanks, Shalom
