'*****' has not been declared

[Beckmann, Niklas]

Dear members of the gnuradio mailing list,


since 2 days I am trying to fix this error. So maybe one of you guys can help 
me...

I am grateful for any help.


I have the following code, which is the impl.h file of a block from my oot 
module.


#ifndef INCLUDED_FLORIANINETS_BASEBAND_DEROTATION2_IMPL_H
#define INCLUDED_FLORIANINETS_BASEBAND_DEROTATION2_IMPL_H

#include 

namespace gr {
namespace FlorianiNets {

class baseband_derotation2_impl : public baseband_derotation2
{
private:
float f_mu;
float f_error;
gr::digital::constellation_sptr;
gr::digital::c_constellation;
float wrap_phase(float phi);

public:
baseband_derotation2_impl(float mu,
  gr::digital::constellation_sptr,
  gr::digital::constellation);
~baseband_derotation2_impl();

// Where all the action really happens
int work(int noutput_items,
 gr_vector_const_void_star& input_items,
 gr_vector_void_star& output_items);
};

} // namespace FlorianiNets
} // namespace gr

#endif /* INCLUDED_FLORIANINETS_BASEBAND_DEROTATION2_IMPL_H */

When I run make, I get this error list, and I simply don't know why:

I tried everything, what I know to fix this, but I did not manage to do so.
Maybe someone else has a good advice.

Thank you very much,
Nik

Hi Nik,

if you use names from a different header file, you'll need to include that header, 
otherwise your compiler can't know what that name means! In this case, you need to include 
the header that defines gr::digital::constellation and gr::digital::constellation_sptr. 
That would be done by


#include 

in your header.

(note: that's a bit of a basic C++ thing, you need to declare the things you use in each 
compilation unit *before* you use them.)


Best regards,
Marcus

PS: kind of surprising to pass in both a shared pointer to a constellation object, and to 
pass-by-value (i.e., make a copy) another constellation object. Hope that makes sense!

Compatibility_Ubuntu_GnuRadio_Python

[Info]

Hello,

I have installed GnuRadio 3.10.1.1 and Python 3.10.4 on Ubuntu 22_04

and I run into a problem:

 

There is only a very simple flowgraph:

QT GUI Toggle Switch --> QT GUI LED Indicator

 

At runtime, there is an error in modul: 

"/usr/lib/python3/dist-packages/gnuradio/qtgui/ledindicator.py", line 79

As I can see, there is a type mismatch between float and whatever?

Has anybody an idea what goes wrong and how can I fix it?

Thanks

Karlheinz Kemna

Re: Compatibility_Ubuntu_GnuRadio_Python

[Marcus Müller]

Hi Karlheinz,

yep, that's a bug, a student of mine hit the same :)
Volker Schroer fixed that upstream[1] and it's included in GNU Radio 3.10.2.0.

Sadly, I don't think this has trickled down into Ubunut's packaging yet.
If you feel adventurous (notice that I'm usually strongly opposing fiddling with 
system-installed data, but here, it does seem like an easy enough fix), by replacing line 
79 in

"/usr/lib/python3/dist-packages/gnuradio/qtgui/ledindicator.py",
the line becomes
self.setMinimumSize(int(maxWidth), int(maxHeight))
(make very sure not to change the indentation of the file).

Best regards,
Marcus

Hi, all!


I will post weekly this project update in this thread, following is last week:


Short version report:( unfortunaly I need to rebuild gr-web)



 Has Done: 1. using latest gr commit to build gr-web. 2. Fix commit missing 
issue.

 TODO: 1. fix the running fail issue.  2. And push the modification to 
marc’s repo.


Full version report: blog 
here

Hi, everyone!

I've been accepted to work with GnuRadio for this year's Google Summer of Code.



The task I intend to implement is porting SIMD code to gr-web through wasm,

which enables gnuradio more extensible and popular through the browser.



I am really sorry, this post seems a bit late due to some unexpected problems 
with the building gr-web from the source.



Last week's blog:

 https://eat4toast.github.io/2022/07/04/week1.html



I will post a weekly update on the mailing list, well the blog will record more 
latest progress.



Yours,

Yao.
