Hi all, 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.

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
