[michaelld]

Can you please explain what you mean by "C++ support in master"? Maybe I'm the only person who doesn't understand, but I doubt it. Having a little background as to what this means and what you're actually doing programming-wise would be useful IMHO, in general & not just for me. Thx!

[noc0lour]

@michaelld it's about C++ generation support in GNU Radio Companion. To be able to generate C++ flowgraphs the blocks needs a stanza in the block.yaml about how to construct them.

[mbr0wn]

Holy 💩

[michaelld]

OK wow this is quite a serious change! Thx for the explanation @mbr0wn & updating the title @noc0lour ... it all makes more sense now to me!

[haakov]

Yeah, it was a little vague, sorry about that. This issue is really just to keep track of which blocks are available for C++ generation as @noc0lour said.

Programming-wise, there are two things that need to be done to add C++ support to a block.

First, the cpp flag will have to be added:

gnuradio/gr-blocks/grc/blocks_add_xx.block.yml

Line 3 in d67fc91

flags: [ python, cpp ]

(GRC will refuse to generate a C++ flowgraph if it contains blocks that don't have this flag)

Second, the block will need cpp_templates:

gnuradio/gr-blocks/grc/blocks_add_xx.block.yml

Lines 43 to 46 in d67fc91

	cpp_templates:
	includes: ['#include <gnuradio/blocks/add_blk.h>']
	declarations: 'blocks::add_${type.fcn}::sptr ${id};'
	make: 'this->${id} = blocks::add_${type.fcn}::make(${vlen});'

[aru31]

Can I work on this issue?

[haakov]

Yes you can :)

gr-dtv WIP here: https://github.com/ncorgan/gnuradio/tree/grc/dtv_cpp

[dkozel]

@ncorgan Hey Nick, Any chance you can shepherd your gr-dtv additions upstream? Incomplete or not they're a seriously useful contribution and I'd hate to see them bit-rot for another 15 months.

[dkozel]

#2573 covers gr-vocoder. I'll rebase and open a new PR unless you're free to do it @haakov?

[ncorgan]

Sure. After work, I’ll see what state it’s in and make a rebased pull request for what’s there.

@dkozel Oh I must've completely missed that somehow. I'll open a new PR.
