[Paraview] Compiling Paraview on CentOS7

[Mathieu Westphal]

Hello Paul

This is an environement variable, so the simplest way is to run paraview
from a terminal :

Applications -> System Tools -> Terminal

Then enter the following command

cd /path/to/your/build/of/paraview
MESA_GL_VERSION_OVERRIDE=3.3 ./bin/paraview


If that works you may consider adding it to your environnement variables in
your .bashrc file
export MESA_GL_VERSION_OVERRIDE=3.3

Best,


Mathieu Westphal
