Qt5 error (Ubuntu 20.04)

ParaView Support
1

Good morning,

I am having problems installing Paraview 5.8 on my Linux machine, through the MPI package included in the webpage. When launching it, it says:
“…/ParaView-5.8.1-MPI-Linux-Python2.7-64bit/bin/…/lib/libQt5Core.so.5: version `Qt_5.12’ not found (required by /usr/lib/x86_64-linux-gnu/libQt5Network.so.5)”

If I “ll” the lib folder, it seems it is properly pointed: “libQt5Core.so.5 -> libQt5Core.so.5.12.8”

What is the problem here?
Kind regards.

I suspect you have a modified LD_LIBRARY_PATH or some such. Try running with LD_DEBUG=libs environment variable set and then pipe the output to a file. Inspecting the file will tell you which Qt5Core library it is trying to load and why.
