Re: linker error when trying to use rational_resampler_base

Hi Dustin,

Without knowing all of the details, I guess the FILTER component could be missing from CMakeLists.txt:

set(GR_REQUIRED_COMPONENTS RUNTIME FILTER)

More details in [1].

Cheers,

Ernest

Hi all,

I get a linker error when trying to use rational_resampler_base. Am I doing something incorrectly?

the relevant snippet of code:

#include <gnuradio/filter/rational_resampler_base.h>

/* ... */

unsigned int interp,decim;

std::vector<float> taps;

/* ... */

gr::block_sptr resampler = gr::filter::rational_resampler_base_fff::make(interp,decim,taps);

gives me the following error when I try to build my project:

undefined reference to gr::filter::rational_resampler_base<float,float,float>::make(unsigned int, unsigned int, std::vector<float, std::allocator<float> > const&)
collect2: error: ld returned 1 exit status

I'm using gnuradio 3.8.0.0 from the Arch Linux community repository.

Thanks,
