Subject: | [Discuss-gnuradio] WX GUI FFT Sink error |
Date: | Tue, 15 May 2012 20:32:35 -0400 |
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. Bill |
