Hello,

I have managed to install gnuradio on a Win 8 and Win 7 machine and it  
seems like most of the block components in gnuradio-companion function  
correctly, except for the WX elements.

When I include a WX block, like the FFT sink, it fails to execute with a  
Python import error:

File “C:\Program Files  
(x86)\gnuradio\lib\site-packages\gnuradio\wxgui\__init_\_.py”, line 32,  
in  
  
from wxgui\_swig import \*  
ImportError: No module named wxgui\_swig

I’ve installed all the 32-bit dependencies for Python 2.7 listed on the  
Ettus page for the Windows install and I’m running the latest stable  
version of gnuradio. I double checked my PYTHONPATH and it does include  
the  
site-packages directory inside of gnuradio, as well as the directory for  
the wx libraries installed in my python directory. Digging around a  
little  
further, I do not see a Python module in any directory for wxgui\_swig.

Why is it looking for a module that doesn’t seem to exist? Or to put it  
another way, what have I done to mess things up?

Thanks,  
-Trevor

Same problem here, fresh install yesterday.  
Examples loaded from  
C:\Program Files (x86)\gnuradio\share\gnuradio\examples  
work fine  
anything from the desktop (including same examples) gives ImportError:  
No module named wxgui\_swig

Who logs in to gdm? Not I, said the duck.

Our build system is having issues with the GNU Radio Windows installers.  
We’re currently working on a solution.
