Re: [Discuss-gnuradio] GNURadio Windows Errors with OsmoSDR

Yes, I’m running from that batch file. I agree, it’s a very bizzare error. I’ve only been able to find a couple mentions to my issue online and they’re all on other platforms like OSX or Linux.

Attached is the dependency check on _osmosdr_swig.pyd – the older dependency checker tool didn’t want to work in Win10 but this one did. I don’t see any erorrs apart from the incorrect checksums it’s reporting in the bottom pane.

Thanks again for your willingness to help. I really want to get GRC up and working properly on this machine and I know how strange this error is.

Patrick,

Just to confirm, you started GRC by running the run_GRC.bat file or the link on the start menu? Assuming so. If not that’s the problem and ignore the rest.

There is little program out there called “dependency checker” that is invaluable for these issues. Download it and find the .pyd module file below with the import error. Open it in that program. It will display the chain of DLLs it is looking for and if something is missing it should appear. (You will get false errors about system libraries and may need to add directories to the search tree path).

So if you run that and there is a missing DLL that seems GR related then let us know which it is , this would indicate a problem in the installer.

Next option is the DLL is somewhere in the system and somehow the GRC isn’t finding it, which would be odd but possible.

It’s a very odd error in general, running an RTL based flow graph is tested when I package the installers.

Hi Kyeong

This is running a GRC file inside of GNURadio Companion. Something is indeed broken.

I simply ran the Win64 installer for GNURadio from the Windows builds site linked by the GNURadio wiki. I recall last year I had this same issue on my Windows system and gave up using GRC on Windows because of it. It’s a pain to load up my linux box every time I want to use GNURadio though.

Thanks for the input

Patrick

Hello Patrick:

Are you running a GNU Radio Python code? Or, are you running a GRC file using GNU Radio Companion?

If you are running a Python code generated from GNU Radio Companion, you should be running that code using "GNU Radio Command Prompt" (which comes with correct library PATH variables).

If you are running a GRC file using GNU Radio Companion, then I guess something is broken..

Also, please note that the GNU Radio Windows distribution comes with its own Python interpreter (which you can use by using GNU Radio Command Prompt", and does not touch or use the Python interpreter on your system.

Regards,
Kyeong Su Shin

제목: [Discuss-gnuradio] GNURadio Windows Errors with OsmoSDR

Hi all on the list,

I’ve been tearing my hair out trying to solve an issue I’m having with a clean install of GNURadio using the Windows builds.

When trying to run a simple flowgraph, with an RTL-SDR source connected to a frequency sink, I receive the following traceback:

Traceback (most recent call last):
File "C:\Users\Patrick\Documents\top_block.py", line 29, in <module>
    import osmosdr
File "C:\Program Files\GNURadio-3.7\lib\site-packages\osmosdr\__init__.py", line 26, in <module>
    from osmosdr_swig import *
File "C:\Program Files\GNURadio-3.7\lib\site-packages\osmosdr\osmosdr_swig.py", line 17, in <module>
    _osmosdr_swig = swig_import_helper()
File "C:\Program Files\GNURadio-3.7\lib\site-packages\osmosdr\osmosdr_swig.py", line 16, in swig_import_helper
    return importlib.import_module('_osmosdr_swig')
File "C:\Program Files\GNURadio-3.7\gr-python27\lib\importlib\__init__.py", line 37, in import_module
    __import__(name)
ImportError: No module named _osmosdr_swig

I think this is a problem with my PATH, or with the installation of GNURadio, but I can’t figure out how to fix it. There is almost no info on anyone else having errors like this with GRC so I’m stumped.

Additionally, on this clean install of GNURadio, I receive over a hundred of errors similar to this one during startup of GRC:

Warning: Block with key "xxx" already exists.
        Ignoring: C:\Program Files\GNURadio-3.7\share\gnuradio\grc\blocks\xxx.xml

I feel as if these two issues might be related in some way.

I would appreciate any help. My system is running Win10 and I have the latest Python 2.7 installed.

Thanks to all,

Patrick
