|Subject:||Re: [Discuss-gnuradio] [Openlte-discuss] Segmentation fault in when using gnuradioresampler block in c++ flowgraph [SOLVED]|
|Date:||Sun, 6 Oct 2013 12:52:11 +0000|
after experimenting and searching a little bit I found the solution:
gr::filter::rational_resampler_base_ccf sptr resampler_filter;
resampler_filter = gr::filter::rational_resampler_base_ccf::make(…);
top_block—> connect(samp_src,resampler_filter,0) ….
And so on,
The resampler filter does not work but I need to work on it a little bit more.
If anyone experiences the same problem, this just the solution for how to connect blocks in c++, I guess.
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.
gr::top_block_sptr top_block; // Included hier_block2.h
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?
