Hello all, I am currently trying to migrate an OOT module that uses an FFT object internally from GNU Radio version 3.8 to 3.9.
In my .h file I have got this: //old: gr::fft::fft_complex d_fft_calculator; gr::fft::fft_complex_fwd d_fft_calculator; and in the constructor member initializer list this: //old: d_fft_calculator(gr::fft::fft_complex(pow(2.0, 10 + mode), true, 1)), d_fft_calculator(pow(2.0, 10 + mode), 1), The module compiles without a problem but when I start the flowgraph I get the message "ImportError: /usr/local/lib/libgnuradio-dl5eu.so.1.0.0: undefined symbol: _ZN2gr3fft3fftISt7complexIfELb1EED1Ev". It looks to me that somewhere "fft_complex" is still called behind the scenes but I can't see where. Can anyone tell me how I need to correct this? FYI, I have recreated the module and the blocks with gr_modtool and then copied the relevant code from the old to the new version. Thank you very much and kind regards, Ralf
