OPEN GL installation queries

[sundararajan]

Hi guys
I have a problem getting OpenGl to work on my laptop. My laptop has a nvidia card. The output of glxinfo command is

name of display: :0.0
display: :0 screen: 0
direct rendering: Yes
server glx vendor string: NVIDIA Corporation
server glx version string: 1.4


I tried glx gears and it works perfectly fine.

I have been trying to develop a few things using Open gl and when I try compiling my scons script for the program I get the following error

scons: Reading SConscript files ...
Building for OS posix
Setting Linux specific flags
scons: done reading SConscript files.

Can anyone help me with this problem
