[Discuss-gnuradio] gnuradio-next -- GRC FFT -- OpenGL Persistence Crash

[Ben Hilburn]

Hey all -

I'm using gnuradio-next (testing CMake and such).  If I use the OpenGL FFT in GRC, and click the "Persistence" checkbox, the flowgraph crashes and spits this out:

File "/usr/lib/python2.7/site-packages/OpenGL/error.py", line 208, in glCheckError

    baseOperation = baseOperation,

OpenGL.error.GLError: GLError(

err = 1282,

description = 'invalid operation',

baseOperation = glAccum,

cArguments = (GL_LOAD, 1.0)

)

If I don't use OpenGL, the persistence feature works just fine.  Has anyone else seen this error before?

My setup:

linux; GNU C++ version 4.6.1 20110819 (prerelease); Boost_104700; UHD_003.003.000-13899cd

Python 2.7

GNURadio next branch, commit: 882089131a00da24

python-opengl 3.0.1-2

Cheers,

Ben
