*Hi everyone,*

*I installed gnuradio using binary packages  provided by ETTUS RESEARCH
.*



*         I installed gnuradio 3.7.2.1 and processor Im using is intel
i3
64bit.*
*Everything installed with no issues but when  using constellation
block,
Im facing the some problem and below is the error *

 File "/home/sandhya/top_block.py", line 16, in <module>
    from gnuradio.wxgui import constsink_gl
  File "/usr/lib/python2.7/dist-
packages/gnuradio/wxgui/constsink_gl.py", line 25, in <module>
    import const_window
  File
"/usr/lib/python2.7/dist-packages/gnuradio/wxgui/const_window.py",
line 25, in <module>
    import plotter
  File
"/usr/lib/python2.7/dist-packages/gnuradio/wxgui/plotter/__init__.py",
line
22, in <module>
    from channel_plotter import channel_plotter
  File
"/usr/lib/python2.7/dist-packages/gnuradio/wxgui/plotter/channel_plotter.py",
line 23, in <module>
    from grid_plotter_base import grid_plotter_base
  File
"/usr/lib/python2.7/dist-packages/gnuradio/wxgui/plotter/grid_plotter_base.py",
line 24, in <module>
    from OpenGL import GL
  File "/usr/lib/pymodules/python2.7/OpenGL/GL/__init__.py", line 11, in
<module>
    from OpenGL.GL.VERSION.GL_1_2 import *
ImportError: No module named VERSION.GL_1_2

*Checking out the previous thread I found two solutions*

"First, you can probably install python-opengl on your system. Or you
can
turn of GL support by editing the file in (probably)
/usr/local/etc/gnuradio/conf.
d/gr-wxgui.conf and change the 'style = auto' option to 'style = nongl"



*But either of the two solutions are working and throwing me the same
error.*

*Anyone can help me on this *



*Thanks*
*sandhya*

The constellation sink does not have a non-OpenGL version, so you have
to
have OpenGL support (software and hardware). I'm guessing there is
something more you need to do to get opengl on your system.
