[Discuss-gnuradio] Fedora7 and usrp_ra_receiver.py

[Lars E. Pettersson]

Hi!

For some reason that I can not understand, I can not get 
usrp_ra_receiver.py running, see attached traceback. As I am new to both 
python and Gnuradio, I am not sure exactly where to start diagnosing 
this. Any ideas? The other graphical examples seem to work.

I am using the svn-version of gnuradio on a fully updated Fedora7 x86_64 
installation.

I tried installing the Fedora compat-wxPythonGTK2 package, but that did 
not solve the problem (it even made it worse as I then could not run the 
other examples, such as usrp_fft.py). The traceback then was:

address@hidden src]$ usrp_ra_receiver.py
Traceback (most recent call last):
  File "/usr/local/bin/usrp_ra_receiver.py", line 28, in <module>

line 173, in <module>
    EVT_DATA_EVENT = wx.PyEventBinder (myDATA_EVENT, 0)
AttributeError: 'module' object has no attribute 'PyEventBinder'

The usrp_psr_receiver.py also seem to have issues:
