    Hi,<br>
    <br>
    I'm still trying to build paraview 5.3 with Qt4.8. As paraview
    superbuild was failing on my desktop (centos 6.9, Nvidia GPU), I
    build paraview by hand and it is running now with and without
    pvserver connection<br>
    .<br>
    The problem went back with building same paraview version on the
    cluster frontend: CentOS 6.7, no GPU. The compilation is successfull
    but launching paraview I get some errors with OpenGL:<br>
    <br>
    <tt>ER</tt><tt>ROR: In
/kareline/data/begou/<wbr>PARAVIEW5/paraview/VTK/<wbr>Rendering/OpenGL2/<wbr>vtkOpenGLRenderWindow.cxx,
      line 825</tt><tt><br>
    </tt><tt>vtkXOpenGLRenderWindow (0x2280fb0): GL version 2.1 with the
      gpu_shader4 extension is not supported by your graphics driver but
      is required for the new OpenGL rendering backend. Please update
      your OpenGL driver. If you are using Mesa please make sure you
      have version 10.6.5 or later and make sure your driver in Mesa
      supports OpenGL 3.2.</tt><tt><br>
    </tt><tt><br>
    </tt><tt>ERROR: In
/kareline/data/begou/<wbr>PARAVIEW5/paraview/VTK/<wbr>Rendering/OpenGL2/<wbr>vtkXOpenGLRenderWindow.cxx,
      line 812</tt><tt><br>
    </tt><tt>vtkXOpenGLRenderWindow (0x2280fb0): failed to create

    </tt><tt>vtkXOpenGLRenderWindow (0x2280fb0): GLEW could not be
      initialized.</tt><br>
    <br>
    I've built and installed mesa from mesa-17.0.4.tar.gz using:<br>
    <tt>./configure \</tt><tt><br>
    </tt><tt>PKG_CONFIG_PATH=/share/apps/<wbr>paraview-5.3.0/lib/pkgconfig \</tt><tt><br>
    </tt><tt>--prefix=/share/apps/paraview-<wbr>5.3.0 \</tt><tt><br>
    </tt><tt>--disable-osmesa --enable-gallium-osmesa
      --enable-gallium-llvm \</tt><tt><br>
    </tt><tt>--with-llvm-prefix=/share/<wbr>apps/paraview-5.3.0</tt> <br>
    <br>
    With several requested libraries:<br>
    libxshmfence-1.2.tar.gz<br>
    libxcb-1.12.tar.gz<br>
    libXau-1.0.8.tar.gz<br>
    pthread-stubs-0.3.tar.gz<br>
    xcb-proto-1.12.tar.gz<br>
    libdrm-2.4.70.tar.gz<br>
    llvm-4.0.0.src.tar.xz<br>
    all under <tt>/share/apps/paraview-5.3.0/ </tt><br>
    <br>
    I've checked with strace that paraview was loading libGL in
    /share/apps/paraview-5.3.0/lib and not the system one, requested by
    other application (frontend is in production and I cannont break
    these libraries used by other softwares).<br>
    <br>
    <tt><br>
    </tt>I must confess I'm not familiar at all with these libraries and
    environments, mesa or osmesa, GPU or not GPU, of screen rendering...
    all documentation deeping in obscure details while I'm searching to
    understand these concepts. <br>
    it is clear for me that on the nodes (without GPU) I will use OSMesa
    and no GUI, but on the frontend where I need GUI ???<br>
    <br>
    Thanks for your advices and sorry if this is a very basic <span class="gmail-m_4473869898165173759gt-baf-word-clickable">lack of understanding from myself.</span><br>
