[Discuss-gnuradio] plotter_base.py problem

[Miguel A. Vallejo, EA4EOZ]

Hello!

I'm trying to play a bit with gnuradio and a funcube dongle pro but I'm 
having problems making gnuradio work. I'm using a fresh ubuntu 11.04 
install and gnuradio 3.4.0 built from sources.

Everytime a fft display is used, I get the same error. For example, 
using FunCube Dongle Pro example:



address@hidden:~$ FCDongle/gr-fcd/apps/fcd_fft_wx.py
Traceback (most recent call last):
  File 
"/usr/local/lib/python2.7/dist-packages/gnuradio/wxgui/plotter/plotter_base.py", 
line 158, in _on_paint
    GL.glClearColor(*BACKGROUND_COLOR_SPEC)
  File "/usr/lib/pymodules/python2.7/OpenGL/error.py", line 208, in 
glCheckError
    baseOperation = baseOperation,
OpenGL.error.GLError: GLError(
        err = 1280,
        baseOperation = glClearColor,
        cArguments = (1, 0.976, 1, 1)
)


And testing this little GUI example from 
http://www.funwithelectronics.com/?id=10


address@hidden:~./simplegui.py
Traceback (most recent call last):
  File 
"/usr/local/lib/python2.7/dist-packages/gnuradio/wxgui/plotter/plotter_base.py", 
line 158, in _on_paint
    GL.glClearColor(*BACKGROUND_COLOR_SPEC)
  File "/usr/lib/pymodules/python2.7/OpenGL/error.py", line 208, in 
glCheckError
    baseOperation = baseOperation,
OpenGL.error.GLError: GLError(
        err = 1280,
        baseOperation = glClearColor,
        cArguments = (1, 0.976, 1, 1)
)


And so on... Any ideas? I'm totally lost.

Thank you in advance!
