Thanks a lot Burlen, all is running fine now with this setup for
mesa on the front-end.<br>
With Paraview, I had to add some parameters for ffmpeg-3.3 libraries
that were not automaticaly loaded and set LD_LIBRARY_PATH to load
llvm is a separate directory from mesa but all runs fine now:<br>
<tt>export
LD_LIBRARY_PATH=/share/apps/mesa/17.0.6-x11-swr/lib/:$LD_LIBRARY_PATH</tt><tt><br>
</tt><tt>export
LD_LIBRARY_PATH=/share/apps/llvm/4.0.0/lib:$LD_LIBRARY_PATH</tt><tt><br>
</tt><br>
and for cmake:<br>
<tt>cmake ............</tt><tt><br>
</tt><tt> -DPARAVIEW_ENABLE_FFMPEG=ON \</tt><tt><br>
</tt><tt> -DFFMPEG_ROOT=/share/apps/ffmpeg-3.3-GCC485 \</tt><tt><br>
</tt><tt>
-DCMAKE_EXE_LINKER_FLAGS="-Wl,-rpath-link=/share/apps/ffmpeg-3.3-GCC485/lib:/share/apps/llvm/4.0.0/lib:/share/apps/mesa/17.0.6-x11-swr/lib
-L/share/apps/ffmpeg-3.3-GCC485/lib -lswresample -lavutil
-lavformat -lavcodec -lswscale -lavdevice -lavfilter" \</tt><tt><br>

OK. to accomplish this, first do a Mesa build configured as
follows(glx+software rendering)<br>
<blockquote><tt>../mesa-17.0.6/configure --enable-texture-float
--enable-glx --disable-dri --disable-egl --disable-gles1
--disable-gles2 --disable-gbm --disable-driglx-direct
--disable-xvmc --with-gallium-drivers=swrast,swr
--prefix=/work/apps/mesa/17.0.6-x11-swr<br>
</tt></blockquote>
make sure ParaView can find it, and configure ParaView as follows<br>
<blockquote><tt>export
LD_LIBRARY_PATH=/work/apps/mesa/17.0.6-x11-swr/lib/:$LD_LIBRARY_PATH<br>
cmake
-DOPENGL_INCLUDE_DIR=/work/apps/mesa/17.0.6-x11-swr/include
-DOPENGL_gl_LIBRARY=/work/apps/mesa/17.0.6-x11-swr/lib/libGL.so
~/work/ParaView/<br>
</tt></blockquote>
when you run ParaView the "help/about" dialog should report VMWare
Mesa 17.0.6 Gallium on llvmpipe.<br>

- one build for the nodes whitout GUI as they have no windowing
system nor GPU (I build this using the wiki documentation) <br>
- one build for the front end with GUI: it has no GPU but a
windowing system (this is the blocking point at this time) <br>
- one build on the users workstations where a GPU and a
windowing system are available (this is working too thanks to
the wiki documentation) <br>
<br>
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. <br>
<br>
May be should I post on the Mesa forum ? <br>

<blockquote type="cite">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. <br>
<br>
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. <br>

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