[Discuss-gnuradio] Segmentation fault in when using gnuradio resampler block in c++ flowgraph

[Dincer Beken]

Hi all,

 

I want to connect the rational resampler to the block called “state machine”. Whenever I invoke the rational resampler I get an “SEGMENTATION FAUL” error. I use an C++ flowgraph.

 

Header file:

gr::top_block_sptr top_block; // Included hier_block2.h

gr::filter::rational_resampler_base_ccf::sptr resampler_filter;

 

Source File:

resampler_filter->make(1536,1000,std::vector<float>(1,1));

top_block->connect(samp_src, 0, resampler_filter, 0);

top_block->connect(resampler_filter,0, state_machine, 0);

 

 

 

 

What am I Missing? Does the header not find the source file rational_resapmler_base_cf_impl.c? Do I have to use for some reason another (PFB) filter? How can I invoke a gnuradio block like that in general in such a flowgraph?

 

How do I have to invoke the pointer for the resampler block?

 

Thanks,

Dincer
