RichThanks,I'm not sure where to go from here. What else needs to happen to call kernel::fir_filter_ccf?To my CMakeLists.txt file I added FILTER to the dependency list:I'm having some trouble getting my code to compile. I get the following error:To my *_impl.h file I added the following:
error: ‘kernel’ does not name a type
kernel::fir_filter_ccf *d_shape_filter;
#include <gnuradio/filter/fir_filter.h>
private:
kernel::fir_filter_ccf *d_shape_filter;
set(GR_REQUIRED_COMPONENTS RUNTIME FILTER)

hilbert_fc.cc and filter_delay_fc both use kernel::fir_filter in a relatively easy to understand way.

_______________________________________________Hi all,
Would someone please recommend a good starting point in C++ source code
that demonstrates how one uses the kernel::fir_filter. I started
following the pfb_clock_sync method of implementing it, but then
realized this had been customized a bit for the polyphase approach.
I'm not doing anything fancy, I'm building a modulator and need to pass
symbols through a shaping filter. The shaping filter is what I need the
FIR filter for.
Appreciated,
Rich
