Yes Burlen, this is exactly what I try to do:
- one build for the nodes whitout GUI as they have no windowing system nor GPU
(I build this using the wiki documentation)
- one build for the front end with GUI: it has no GPU but a windowing system
(this is the blocking point at this time)
- one build on the users workstations where a GPU and a windowing system are
available (this is working too thanks to the wiki documentation)
On the front-end I have a system libGL but too old for Paraview 5 and it is
requested by other commercial softwares. This is why I try to build a new mesa
from sources for Paraview. I use the module environment then to set the
LD_LIBRARY_PATH and PATH order to reach the right libraries and, as strace show,
it seams to work fine. So I suppose it is a mesa configuration mistake in my build.
May be should I post on the Mesa forum ?

that's the point. this allows you to run without the windowing system or GPU
on the cluster. Most cluster have neither. If you wanted to provide the GUI
then I would suggest you have two installs of both ParaView and Mesa. One
based on OSMesa, the other based on some X11 enabled OpenGL. Alternatively you
could install only the OSMesa capable pvserver as suggested in previous email
and direct your users to the ParaView GUI enabled binaries that Kitware
provides on their web site. The latter is what I have been doing.
As an aside, it gets messy when you have two libGL in the same build. One need
to be very careful about library dependencies. It is possible to do this if
one is very careful during link time. However as far as I know this has not
been supported for quite a long time in VTK/ParaView, and I think it would
require some reorganization of VTK OpernGL classes.

Hi Burlen,
this Mesa setup does not provide libGL requested to build paraview with GUI
enabled :-(
It is OK for the cluster nodes but not for the frontend where I need this GUI
even with no GPU installed.
