Re: [Discuss-gnuradio] Topic:PyQt4,gnu radio modules not found

Hello Kyeong,

Windows Version

I tried to open GNU Radio Command.But the moment i click the GNU Radio Command prompt,it exits.I googled to get a solution for this issue,but unfortunately couldn't find any. When i check the Program compatibility of the GNU Radio command prompt,I see the below error.What could be the issue here?

The specified path doesn't contain a valid program.Please select a valid program ending with exe

C:\Program Files\GNURadio-3.7\bin\run_gr.bat

Linux Version

Also,I installed the GNU Radio after installation of Ubuntu using Virtualbox.I tried

1.executing uhd_fft.py -a type=usrp1 -f 935M -s 2M.Got this ERROR :unable to access X display ,is $ X DISPLAY set properly?I set export DISPLAY=:0.That also didnt work.

2.Executing gnuradio-companion ,which gave me ERROR:Segmentation fault.

I'm blocked ,for both windows and ubuntu versions of GNU Radio :(

regards

Prasoon

Hello Prasoon:

That GNU Radio distribution has its own local Python and dependency installations. When you run GNU Radio Companion or GNU Radio Command Prompt, initialization scripts will automatically reconfigure the paths of the dependencies to use those local packages. That does not happen if you use the default Windows Command Prompt.

Did you use the GNU Radio Command Prompt to execute your Python codes?

Maybe some of you have noticed that I've been working on getting volk
1.4 and gnuradio 3.8 to compile and cross compile for ARM with clang
(specifically clang 7 but seems to work down to at least 3.8).

I'm happy to say that it's working pretty well now! Volk with neon
support works and most of gnuradio compiles without any problems.

I've uncovered some small bugs/quirks in the process and have
submitted a bunch of issues and a pull request to volk:
https://github.com/gnuradio/volk/pull/223

Volk currently has 11 open pull requests, some without any response
from the maintainers, which leads me to my question: How's volk doing?
Are more maintainers/testers needed in some specific area?

Hi Prasoon - Welcome to the world of GNU Radio! A few questions to help
clarify your query:
What OS are you using? Guessing Windows but just checking.

How did you install GR? and its dependencies? ... from source, from an
archive, something else?
Cheers! - MLD

Hi Albin - Thank you for all of your work here! I haven't tested it out, but reading through it (and other PRs) you're really helping Volk along for NEON.

I'm not going to review this PR, just comment about PRs in general ... for now.

In general for GR / Volk PRs: Keep them targeted and simple; a single topic is best if at all possible. You can make one PR require another one, in order to keep complexity of any specific PR down.

If a given PR has multiple topics, please make them different commits. A single commit with multiple topics is very unlikely to be committed.

Thus for this specific PR, I'd advise you to split off each topic into a different PR:

+ Removed duplicate symbol in volk_16i_max_star_horizontal_16i.s

+ Fixed old syntax in volk_16i_max_star_horizontal_16i.s

+ Added clang to gen/archs.xml

+ Append CMAKE_ASM_FLAGS to ARCH_ASM_FLAGS (for cross compilation)

+ Added overrules avx512f avx512cd

+ Don't overwrite CMAKE_ASM_FLAGS

In this manner, we can determine the validity of each commit / PR. You can note in any specific PR that it depends on some other PR; that's totally OK & we'll work with them to get things going.

Anyway that's my $0.02 worth on the matter. Thanks again for heading down this path! - MLD
