Thanks a lot Burlen, all is running fine now with this setup for mesa on the front-end. 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:
export LD_LIBRARY_PATH=/share/apps/mesa/17.0.6-x11-swr/lib/:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=/share/apps/llvm/4.0.0/lib:$LD_LIBRARY_PATH

and for cmake:
cmake ............
   -DPARAVIEW_ENABLE_FFMPEG=ON \
   -DFFMPEG_ROOT=/share/apps/ffmpeg-3.3-GCC485 \
-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" \
   -DVTK_FFMPEG_AVCODECID=ON \
.......

OK. to accomplish this, first do a Mesa build configured as follows(glx+software rendering)

    ../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

make sure ParaView can find it, and configure ParaView as follows

    export LD_LIBRARY_PATH=/work/apps/mesa/17.0.6-x11-swr/lib/:$LD_LIBRARY_PATH
    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/

when you run ParaView the "help/about" dialog should report VMWare Mesa 17.0.6 Gallium on llvmpipe.

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.
