Re: GNU 3.8.0.0 doesn’t show result after execute & run_gr.bat

[Geof Nieboer]

Wei-Wen,

1- What generation is your CPU?  Does it have AVX/AVX2 extensions?  If not, that is likely the cause of this error, two others have reported it as well

2- If so, the "fix" for the moment is to download the more stable 3.7.13.5 windows installer (you can have both installed at the same time) and try using that.  This has worked for others

Please keep an eye out for a new GR 3.8 Windows release.  I am planned on releasing one "soon" (probably in the next 30 days)

Thank Shin!

Your description of run_gr.bat makes me clear about the physical meaning of it!  

For problem 1, I uninstalled 3.8.0.0 and install 3.7.10 instead, and the plot pop out. I don’t know what’s wrong with 3.8.0.0. But if anyone has the same problem, you can try install 3.7.10

Hello Wei-Wen:

First, Windows tends to behave erratically when you run scripts by just typing their file paths (tends to mix up binary/library paths; remember that CP/M-like OSs do not support shebang). So, I suggest trying "python name_of_a_script.py" instead of "name_of_a_script.py" when using Windows.

Did you run your scripts on GNU Radio Command Prompt? If so, you can simply ignore run_gr.bat. run_gr.bat _is_ what is used to initiate GNU Radio Command Prompt, so you do not need to use it again if you are already on GNU Radio Commmand Prompt.  GNU Radio Command Prompt is just a generic Windows command prompt, but with a few additional variables configured to deal with customized Python binary/library paths. 

Regards,

Kyeong Su Shin

Hi,

I am a starter of gnu radio. I followed the tutorial on the wiki, simply add the signal source, throttle, QT time sink. When I run the  flow graph, there is no result plot pop out. Instead, the command line shows: done(return code -1073741795). Can you tell me how can I see my result? I would like  both plot result on grc and export data to .dat file in the directory. 

Another question is run_gr.bat filename.py on the download document for windows website. I cannot tell what is the purpose of the run_gr.bat, and might do it wrong.

I run gnu radio in Windows 10.

Thank you
