<div>Hello<br><br></div>
Are you building in a VM ?<br><br></div>
In any case, this should do the trick :<br>MESA_GL_VERSION_OVERRIDE=3.3 ./bin/paraview<br><br><br></div>
Best,</div>

<p>Dear All</p>
<p>My colleagues and I would like to use Paraview to post-process FEA's results (mechanical and CFD and son on).</p>
<p>I compilled the latest Paraview release on my CentOS 7 using mesa3D (from CentOS repository + Qt5 + openMPI + ...) to emulate openGL libraries, I still have a warning from Paraview and a compatibility issue; If I choose OpenGL instead OpenGL2 in ccmake, it asks for Qt4 instead of Qt5</p>
<p>I think this topic has ever been tackled by the community, so Where can I find advices to finalize it?</p>
<p>Thanks for any feedback</p>
<p>Paul</p>
