gnuRadio 3.8

Can anyone tell me how can i install gnuradio 3.8 on Ubuntu 18.0.4 LTS? I
have tried these two instructions but i have the same result my laptop

Are you sure you're using the latest gqrx code ?!?

Here I have :
find_package(Gnuradio REQUIRED COMPONENTS analog audio blocks digital
filter fft)

With upper case 'G'.

and my gnuradio 3.8 install has GnuradioConfig.cmake installed.

Cheers,

Hi Sarandis,

In the first version of your attempt, I’ve also seen this problem

It is caused by your laptop running out of memory during the

make -j 4

step.   It can probably be fixed by running

make

instead.   The -j 4 command causes 4 simultaneous threads to run, using up
all the memory.
 
It will take hours to “make” however.

Best regards

Glen

Hi

find the number of CPUs in your system  with command:

    cat /proc/cpuinfo | grep processor | wc -l

don't use all available CPU when using make -j (example make -j3 if you 
have 4 CPUs)


Regards, Christophe

clear buffers of stuck chain

2020-02-05 Thread Eitan Hetzroni
hi,
i am using a gnuradio zigbee chain , and sending alot of packets.
after a certain point, it stops sending packets(or does very slowly).
can i somehow increase the buffer(message loop) or force it to clear the
message loop?

thanks

Important request, participation in software development study

2020-02-05 Thread ivandarioarroyo
Dear Engineers,

When I write this message, I think I am writing to the best software developers 
in the world, or to those who are in the process of being one. I write to ask 
you a favor. I am a UMA PhD student and I study the use of formal and 
non-formal models in the software industry.

According to 9 investigations, UML is not being used as it should, but the 
developers use their own models, designed by them or by their companies. 
However, these investigations have not included professionals like you, so I 
want to ask you to help me by answering this survey:

If you have a Google account:
https://docs.google.com/forms/d/e/1FAIpQLSdG4bhNWfU3vzSKwG-0j8NuGW47_xmSY1ftF33gaNAZsU25kA/viewform

I also ask you to send this survey to other developers that you know and 
respect.

Please help me, I promise that your contributions will be recognized in the 
publications that are possible, therefore, as an optional field I have included 
the name and email. My biggest goal is to unify all non-formal models to create 
a modeling language that is the heritage of the industry, built by all of us.

Yes - sorry I had patched that to lower case as a test but only after 
testing and hitting this issue - it was late :\


This is the actual error unpatched:

  Could not find a package configuration file provided by "Gnuradio" 
with any

  of the following names:

GnuradioConfig.cmake
gnuradio-config.cmake


and my gnuradio 3.8 install has GnuradioConfig.cmake installed.


OK fixed that. Because we don't have a gnuradio-devel package I put the 
gnuradio cmake files in gnuradio-utils instead - was not important at 
the time as they were not used. That error goes away with gnuradio-utils 
added to BRs.

Looks like mageia has split the c++ gmp bindings into libgmpxx-devel
make sure you have that installed.

Shouldn't that be libgmp-devel & libgmpxx-devel ?

The "Found gmp, version 6.2.0" means he found a pkg-config file.

Then after, using the data from the .pc file it tries to find gmpxx.h
and libgmpxx.so and libgmp.so.  It can find the last one, but not the
two first ( see the "missing GMPXX_LIBRARY GMP_INCLUDE_DIR" ).

No that would only be for i586, gmpxx-devel is a virtual provide that is 
arch agnostic.


We always try to use pkgconfig(gmpxx) in preference rather than any 
other in .spec files if they are available, which is why I was so upset 
when you dropped the .pc's from these packages.

I just found my mistake, I had edited the wrong version of the .spec /o\ 
and thanks to your comment I double checked. The gmp* -devels were 
missing from the requires.


gqrx is now building against gnuradio-3.8 (with .pc files) and gr-iqbal 
and gr-osmosdr without.


Thanks again for your help explanations.

Will the 3.8 updates be merged and released soon?

Link not found for USRP FPGA manual

Hi community,

I want to learn about programming the USRP2 FPGA.

The link about the FPGA manual doesn't work

Any help of where to find such manual?

Hi Laura,

Thanks for pointing this out. We will get that link fixed in the manual. I
think it is just an issue with the recent generation of the manual, since
we just merged the FPGA repo into UHD. files.ettus.com/manual/ is built
from the current master branch of UHD.

You can see the manual for the latest stable version of UHD (3.15.0.0)

Re: Link not found for USRP FPGA manual

2020-02-05 Thread CEL
Hi Laura,

I believe such questions are better suited for the usrp-users mailing
list, because working on the USRP2 FPGA has little to do with GNU Radio
itself!

You're right, that link is dead in the UHD 4.0.0.0 documentation, but
you're probably not using UHD 4 anyway: Your installation method for
UHD probably came with the same documentation, but for specifically the
version you're using (maybe in a separate package, it depends), and
that would contain the FPGA manual.

Generally, I honestly wouldn't dive into programming FPGAs unless there
is a very very good reason you *must* use the FPGA – that's digital
hardware design, and that's a whole league of complexity and new
paradigms that can take months to basically come to terms with.

Best regards,
Marcus

Finding GNU Radio 3.8 Compatible Versions Of OOT Modules

2020-02-05 Thread Luke Stutters
Dear GNURadioers,

I was at FOSDEM 2020 and enjoyed the talks.

I am new to GNU Radio and I have ported a couple of OOT modules to GNU
Radio 3.8. I found the porting tool very helpful but there are usually some
additional Python 3 and cmake changes that are needed too.

What is the best way to share this work? I could see some 3.8-related pull
requests for projects on Github - is there an official system to find
3.8-compatible versions of OOT modules?

Many thanks,

Generally, the place to start looking for GNU Radio module is
cgran.org. Our fantastic volunteers (hey, Nicolas and Marc and others!)
have just last week added a new column: supported GNU Radio versions. 

Sadly that column isn't overly well-populated so far – we expect that
to change soon; it's a rather easy field in the Manifest of such OOTs. 

Best regards,
Marcus
