Re: [Discuss-gnuradio] Unable to use WX widgets

[Sandhya G]

well i'm running into new problem using constellation block .

  File "/home/sandhya/top_block.py", line 16, in <module>
    from gnuradio.wxgui import constsink_gl
  File "/usr/lib/python2.7/dist-packages/gnuradio/wxgui/constsink_gl.py", line 25, in <module>
    import const_window
  File "/usr/lib/python2.7/dist-packages/gnuradio/wxgui/const_window.py", line 25, in <module>
    import plotter
  File "/usr/lib/python2.7/dist-packages/gnuradio/wxgui/plotter/__init__.py", line 22, in <module>
    from channel_plotter import channel_plotter
  File "/usr/lib/python2.7/dist-packages/gnuradio/wxgui/plotter/channel_plotter.py", line 23, in <module>
    from grid_plotter_base import grid_plotter_base
  File "/usr/lib/python2.7/dist-packages/gnuradio/wxgui/plotter/grid_plotter_base.py", line 24, in <module>
    from OpenGL import GL
  File "/usr/lib/pymodules/python2.7/OpenGL/GL/__init__.py", line 11, in <module>
    from OpenGL.GL.VERSION.GL_1_2 import *
ImportError: No module named VERSION.GL_1_2

Checking out the previous thread I found two solutions

"First, you can probably install python-opengl on your system. Or you can turn of GL support by editing the file in (probably) /usr/local/etc/gnuradio/conf.d/gr-wxgui.conf and change the 'style = auto' option to 'style = nongl"

But either of the two solutions are working and throwing me the same error.

Anyone can help me on this

Thanks

Thanks marcus .
 well all these days I was using  live usb where I was getting different (eg sine wave ) kind of output when I was using WX-GUI scope sink so I thought it would be missing some package so I wasn't able to see that output .

well thanks ...

Hi,
these are warnings, and you won't be able to use
ctrlport.monitor_performance, but this is not a problem as is.
The Volk warning is just telling you that it's falling back to a safe
implementation, which could be slower in some cases, but will surely work.
To explicitely say it: a warning is a warning that things *might* go
wrong. It is not an error. In most cases, one should not heed it too
much, unless it seems to be related to the problem at hand.

I think you're seeing a single line jumping up and down, and that is
what your data looks like to the wxgui sink.
Try using a larger value for t/s, the < > buttons on the upper button
row on the very left.
Also make sure you're not clogging your CPU with work. If you don't
have a hardware device setting the the sample rate (e.g. a USRP, a
sound card) in your flowgraph, consider simulating that using a
throttle block.

Greetings
Marcus
