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
