I installed the paraview v5.12.0 on centos stream 8. When I tried to run paraview, I encountered an error below.
“./bin/paraview: error while loading shared libraries: libtbb.so.12: cannot open shared object file: No such file or directory.”
Actually, I tried to link libtbb.so.12 to libtbb.so.2. It worked but another error occurred like
“./bin/paraview: symbol lookup error: /root/paraview\_build/bin/…/lib64/libvtkParallelMPI4Py-pv5.12.so.1: undefined symbol: PyExc\_ImportError”
So, I just unlinked it because I don’t know what I did is right and the second error also include the “12.so” similar to the first error. Does any one who has a clue about the problem?
Thanks in advance.

Do you have `LD_LIBRARY_PATH` set in your env vars ?

Thank you for reply. I don’t understand your question properly. Should I add something to LD\_LIBRARY\_PATH to run paraview?

The symptom you are having shows that the wrong lib are being picked up, so you may want to ensure “LD\_LIBRARY\_PATH” is NOT set.

How did you install it ?

Mostly, I just followed the link “[https://gitlab.kitware.com/paraview/paraview/blob/master/Documentation/dev/build.md](https://gitlab.kitware.com/paraview/paraview/blob/master/Documentation/dev/build.md)” for centos 7.
First, I installed packages like
sudo dnf install python3-devel openmpi-devel mesa-libGL-devel libX11-devel libXt-devel qt5-qtbase-devel qt5-qtx11extras-devel qt5-qttools-devel qt5-qtxmlpatterns-devel tbb-devel git
After that I just followed the link like
git clone [https://gitlab.kitware.com/paraview/paraview.git](https://gitlab.kitware.com/paraview/paraview.git)
mkdir paraview\_build
cd paraview
git checkout v5.12.0
git submodule update --init --recursive
cd …/paraview\_build
cmake -GNinja -DPARAVIEW\_USE\_PYTHON=ON -DPARAVIEW\_USE\_MPI=ON -DVTK\_SMP\_IMPLEMENTATION\_TYPE=TBB -DCMAKE\_BUILD\_TYPE=Release …/paraview
finally I didn’t use ninja but make like
make -j 16
The above is all what I did. After make, I just tried to run paraview but it failed.

Any specific reason for you to build ParaView instead of using the paraview binary release from [https://paraview.org/download](https://paraview.org/download) ?

There was no specific reason. I just thought that they are just different ways to install it.
What is the difference between them?

I downloaded binary you said before building it. I just tar it and I can run it without any problem. Thank you very much for your help Mathieu.
