gr-acars is working very well with GNU Radio 3.8, all good. Now I'd like to add two improvements: being able to run multiple processing blocks in parallel (on multiple channels, which libfftw seems hardly able to do due to the non-threadable plan creation) and getting rid of the external FFTW dependency since GNU Radio provides its own FFT wrapper around libfftw3.
So I converted all fftw calls to internal GNU Radio calls, the software compiles fine and now I am stuck with executing since any call to fft::fft_complex* plan_2400 = new fft::fft_complex(N, true); leads to AttributeError: module 'acars' has no attribute 'acars' when executing in GNU Radio Companion, which I attribute to a missing library dependency. I have tried to follow https://wiki.gnuradio.org/index.php/OutOfTreeModulesConfig but the documentation seems outdated since it refers the 3.7.0 requirements. I tried following https://raw.githubusercontent.com/gnuradio/gnuradio/master/cmake/Modules/GrComponent.cmake as used in https://github.com/gnuradio/gnuradio/tree/master/gr-qtgui but that too seems a dead end. 1/ is the CMakeLists configuration include(GrComponent) GR_REGISTER_COMPONENT("gr-acars" ENABLE_GNURADIO_RUNTIME ENABLE_GR_FFT) find_package(Gnuradio "3.8" REQUIRED) the correct way of linking with the FFT library ? 2/ is there a basic example of a simple OOT block linking on such a library somewhere ?
