<div dir="ltr"><div><div><div><div><div>Hi Lloyd,<br><br></div>If you've built ParaView
yourself in the past then doing it with EGL support shouldn't be any
more difficult. The link that Utkarsh sent out covers most if not all of
the necessary information. I'll highlight the fact though that you'll
need to update your NVIDIA drivers to at least 355.11. The dashboard
that's testing ParaView with EGL is running 358.13.<br><br></div>If
you're building 5.0 or 5.0.1 it may not have the newest stuff for easily
finding EGL libraries. For reference, on our EGL dashboard machine the
location that the default NVIDIA driver install puts the EGL libraries
and header files are:<br> EGL_INCLUDE_DIR /usr/include<br> EGL_LIBRARY /usr/lib/x86_64-linux-gnu/libEGL.so<br> EGL_gldispatch_LIBRARY /usr/lib/x86_64-linux-gnu/libGLdispatch.so.0<br> EGL_opengl_LIBRARY /usr/lib/x86_64-linux-gnu/libOpenGL.so<br><br></div>Please let us know if you have any problems.<br><br></div>Best,<br></div>Andy</div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Mar 31, 2016 at 4:51 PM, Utkarsh Ayachit <span dir="ltr"><<a href="mailto:utkarsh.ayachit@kitware.com" target="_blank">utkarsh.ayachit@kitware.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Lloyd,<br>

For a headless server with K80s, you cannot use binaries distributed<br>
from <a href="http://paraview.org" rel="noreferrer" target="_blank">paraview.org</a>. I'd suggesting building ParaView from source with<br>
EGL support (refer to<br>

<br>
Andy, can you point Lloyd to any addition ParaVIew + EGL build<br>
information that may be useful? Thanks<br>
