I'll forward this on to our software guy. I know he's built a
previous version using OSMesa, but I think he was trying to avoid it
this time. <br>
<br>
Thanks for hte information.<br>

<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>

For a headless server with K80s, you cannot use binaries
distributed<br>
from <a moz-do-not-send="true" href="http://paraview.org"

suggesting building ParaView from source with<br>

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

Mine occurs when ssh -X'ing into a remote blade. New
ParaView (i.e., 5.0.0 and later) needs OpenGL 3.2. I
suspect that X forwarding isn't supporting OpenGL 3.2.<br>
