Is it possible to convert c++ written gnuradio flowgraph to .grc format?

Question

I am trying to understand how does gnss-sdr repo works. It is written in C++ and based on gnuradio. Since the code is pretty complicated for me, I would like to see the flowgraph visualized in GNU Radio Companion as.grc file

I am really stuck at this point. Any help is appreciated.

Answer 1

It is possible to convert a C++-written GNU Radio flowgraph to a.grc file, but it would likely require some manual steps. One approach is to use the GNU Radio Companion (GRC) to create a new flowgraph, and then copy and paste the blocks and connections from the C++ code into the GRC flowgraph. Another approach is to use the grcc command-line tool, which can convert C++ code into a GRC file. However, this tool may not work for all C++ flowgraphs, and may require some modification of the code to be compatible.
