In this situation, how to tell 'I am using gr-dvbt' to cmake and make?
I've found some clues in other OOT modules:
set(GR_REQUIRED_COMPONENTS RUNTIME FILTER FFT PMT DIGITAL)
Keywords FFT, DIGITAL seems to indicate gr-fft, gr-digital, respectively.
However, I have no idea where the keywords FFT and DIGITAL come from which part of gr-fft and gr-digital.
I am suspecting that two files, include/api.h and swig/XXXX_swig.i. (But I might be wrong.)
XXXX is either FFT or DIGITAL
In include/api.h: #define XXXX_API
In XXXX_swig.i: #define XXXX_API
According to my guess, I put:
set(GR_REQUIRED_COMPONENTS ... omitted ... DVBT)
But after building and installing, I got an error in the following step:
>>> import myOOTmodule
ImportError: /usr/local/lib/libgnuradio-myOOTmodule.so: undefined symbol: _ZN2gr4dvbt12reed_solomonC1Eiiiiiiii
Am I guessing wrong? Or, gr-dvbt are not available to be used by other OOT modules?
Can it be solved by modifying 1) my code or 2) gr-dvbt?
