Hello everyone,

I have no prior knowledge with GNU Radio. I would like to learn how to 
implement a very basic flowgraph using the C++ API. I have already 
checked the GNU Radio C++ guided tutorial 
 
from the wiki, but I find it very challenging for a beginner like me. 
I was thinking about something simpler like connecting a source and a 
sink as shown in this Python example 
. I have been looking for 
examples in Google but the vast majority of the ones I have come 
across are written in Python. I would be grateful if someone could 
share any guidelines, examples or resources that could help me getting 
started with the C++ API.


Best regards,

Álvaro

Hello Álvaro,

welcome to the GNU Radio community!
I think we could probably help you better why you want to do this in
C++ - most of us, including (and very much so) the long-time users and
core developers use Python to build their flow graphs, because it's
easier and has no performance downside.

Now, you're set on using C++, which is a wise (or: the only) choice in
some environments (typically: embedded devices where you don't want to
have Python), but it's usually not something that a beginner does;
especially, if the Guided Tutorials are a challenge to you.

You will find very minimal examples of how to build and run a flow
graph in qa_gr_top_block.cc in the GNU Radio source code tree under gr-
blocks/lib/ ; look for qa_top_block::t1_run().

Again, I'd advise **strongly** against using C++ flowgraph building,
unless you have a very good reason to do so – all the things we have
that reduce the entry hurdle are very much focused on Python, and you
*will* meet unforeseen obstacles.

Best regards,
Marcus
