Re: [Discuss-gnuradio] 3.7.9.2 Win64 binaries ready + Build scripts

Achilleas,

To troubleshoot that problem:

1- download a program called "Dependency Walker",  (www.dependencywalker.com/)

2- Then with that, open the _filter_swig.pyd file located at C:\Program Files\GNURadio-3.7\lib\site-packages\gnuradio\filter if you used the default settings.  It will give a dialog saying something wasn't found, that's normal.

3- Go to Options->Configure Module Search Order

4- On the bottom right of the window, go to "Browse" and select C:\Program Files\GNURadio-3.7\bin and click "Add Directory", then say "Yes"

5- Repeat that for C:\Program Files\GNURadio-3.7\gr-python27/DLLs

Now on the top left you will see huge tree of all the dependencies... something in there is missing.  IGNORE the entries that look like "API_MS_WIN...", those are fine to be missing.

Please tell me what you are missing.

I suspect since you are running Windows 8, it's the MSVC 14.0 runtime that is missing.  If the missing entries are "UCRTBASE.DLL", "MSVCP140.DLL", and VCRUNTIME140.DLL", that is the problem.  That's a download from Microsoft here: https://www.microsoft.com/en-us/download/details.aspx?id=48145

Some more information about the problem I have running the installed version.

In the GNYRADIO command prompt shell I run python and then

>> from gnuradio import filter 

and I get the following:

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

  File "C:\Program Files\GNURadio-3.7\lib\site-packages\gnuradio\filter\__init__

wig.py", line 24, in swig_import_helper

    _mod = imp.load_module('_filter_swig', fp, pathname, description)

ImportError: DLL load failed with error code -1073741795

Any help is welcome,

thanks

I installed the binary files 

gnuradio_3.7.9.2_win64.msi

on a Win-8 machine succefullyon the default directory.

After running gnuradio-companion file from the Gnuradio 3.7

start menu folder I see a command window opening with message 

"setting gnuradio environment",

then a couple of warnings of the sort:

** (python.exe:5392): WARNING **: Trying to register gtype 'GMountMountFlags' as

 enum when in fact it is of type 'GFlags'

** (python.exe:5392): WARNING **: Trying to register gtype 'GDriveStartFlags' as

 enum when in fact it is of type 'GFlags'

** (python.exe:5392): WARNING **: Trying to register gtype 'GSocketMsgFlags' as

enum when in fact it is of type 'GFlags'

and then the "standard" gnuradio window appears with the import-error warning

------------------------

Cannot import gnuradio.

Is the python path environment variable set correctly?

    All OS: PYTHONPATH

Is the library path environment variable set correctly?

    Linux: LD_LIBRARY_PATH

    Windows: PATH

    MacOSX: DYLD_LIBRARY_PATH

(DLL load failed with error code -1073741795)

-----------------------

any thoughts as to what is going wrong?

thanks

Achilleas
