- We are trying to use ParaView on a cluster without GPUs, so that we had to install OSMesa library (version 7.0.3-7) as explained here: http://www.itk.org/Wiki/Setting_up_a_ParaView_Server#X_Connections - Open MPI 1.2.7rc2 >Does this happen when running locally No, it doesn't. I tried to run the client and the server on my computer and it works. > when running 1 server node? Yes, it does. I tried to run the client and the server on the master node of the cluster: the error occurs when we push the button "apply" (after establishing the connection between client and server and after loading a file) > > 2) When I try to execute some tests with the command: > > > > ctest -I ,,10 > > > > I obtain too many errors in the log file (you can see in attach), for > > example: > > > > /home/utente/ParaView-bin/bin/QVTKCxxTests: error while loading shared > > libraries: libQVTK.so.pv3.6: cannot open shared object file: No such file > > or directory > > > > but the file libQVTK.so.pv3.6 (and the others lib*) is in the directory > > > > /home/utente/ParaView-bin/bin > > > > Could you please help me? > > Thank you in advance! > > Are you running from the build tree or did you do a make install? We run the test in the /home/utente/ParaView-bin directory. We did make install. > If you did a make install, did you compile with VTK_USE_RPATH ON or OFF? VTK_USE_RPATH = OFF (default, I believe) > This probably has something to do with not having rpath and not > setting LD_LIBRARY_PATH. How LD_LIBRARY_PATH has to be set? On each node? Have we to install rpath on each node of the cluster? If you need more information, please let me know.
