Unable to use constellation block

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
from gnuradio.wxgui import constsink_gl
File “/usr/lib/python2.7/dist-
packages/gnuradio/wxgui/constsink_gl.py”, line 25, in

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

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.
