Thankyou all for responding again..:)
I tried to compile paraview and to only hit a wall after wall as I have to
install it to my local folder due to not having administrator privileges..
so i downloaded the binaries last night and checked that it worked..
Today to my surprise, when i try to open paraview in the hpc headnode,
where i downloaded the binaries, it gives the following error..
[vishwa at hpc4 ~]$ paraview
> ERROR: In
> /home/kitware/ParaView-3.6/ParaView3/VTK/Rendering/vtkXOpenGLRenderWindow.cxx,
> line 632
> vtkXOpenGLRenderWindow (0x143bb10): Cannot create GLX context. Aborting.

and i dont' have /home/kitware etc...directory...so i dont understand what
is happening..
I made sure that i included the path of the bin and lib in the newly
downloaded binary..
Any suggestions?
Regards,
vishwa
