Re: [Discuss-gnuradio] Fwd: c++ flowgraph

[Marcus Müller]

Hi Havard,

try the in-tree QA tests, for example gnuradio/gr-blocks/lib/qa_gr_block.cc.

In essence:

#include <gnuradio/top_block.h>
//Include all the headers you'll need, e.g. other blocks' headers
#include <gnuradio/blocks/null_source.h> 
#include <gnuradio/blocks/null_sink.h> 

int main()
{
  gr::block_sptr src1(gr::blocks::null_source::make(sizeof (int)));
  gr::block_sptr dst1 (gr::blocks::null_sink::make (sizeof (int)));

  gr::top_block_sptr tb(gr::make_top_block("mytopblock"));
  tb->connect(src1, 0, dst1, 0); 
  tb->start();
  tb->stop();
  tb->wait();
}

Use gr_modtool so you have a ready-to-build framework; just add yout Cpp
file to the apps directory and edit apps/CMakeLists.txt as necessary.

Best regards,
Marcus
