[Discuss-gnuradio] WX GUI FFT Sink error

[William Pretty Security]

Hello List;

 

While checking my flow-graph I discovered the following problem with the “WX GUI FFT Sink” in

GnuRadio-Companion.

 

When the flow graph is running and you try to check the “Persistance” box you get the following error:

 

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

Traceback (most recent call last):

  File "/usr/local/lib/python2.6/dist-packages/gnuradio/wxgui/plotter/plotter_base.py", line 192, in _on_paint

    GL.glAccum(GL.GL_LOAD, 1.0)

  File "/usr/lib/pymodules/python2.6/OpenGL/error.py", line 194, in glCheckError

    baseOperation = baseOperation,

OpenGL.error.GLError: GLError(

                err = 1282,

                description = 'invalid operation',

                baseOperation = glAccum,

                cArguments = (GL_LOAD, 1.0)

)

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

 

There are no errors at build time …

Has anyone seen this?  I could have sworn it was working OK before.
