So which plugins are installed then?

Does you plugin directory look something like this:

```
~/Apps/ParaView-5.6.0-MPI-Linux-64bit/lib/plugins$ tree
.
├── platforminputcontexts
│ └── libcomposeplatforminputcontextplugin.so
├── platforms
│ └── libqxcb.so
├── sqldrivers
│ └── libqsqlite.so
├── VCGCriticalPointsPlugin.so
├── VCGFlowMapGradientPlugin.so
├── VCGModelPlugin.so
├── VCGModulePlugins.so
└── xcbglintegrations
    └── libqxcb-glx-integration.so
```

Thanks a lot, Louis @louisgag.

What I did was just `mv ./vcgparaview_plugins/* <paraview_path>/lib/plugins`. I think I should have copied the `vcgparaview_plugins/lib/*` and `vcgparaview_plugins/lib/plugins/*` into `~/ParaView-5.6.0-MPI-Linux-64bit/lib/plugins`. Now I have all the VCG\*.so in `~/ParaView-5.6.0-MPI-Linux-64bit/lib/plugins/`. Do I need to load them manually? Because even now, they are not in my local plugin lists when I open Tools → Plugin Manager.

It looks like the instructions on the website are wrong.  
The correct command would be `mv ./vcgparaview_plugins/* <paraview_path>`, i.e., copy the contents of `vcgparaview_plugins/lib` to `<paraview_path>/lib`.  
Relative to ParaView’s path, the files `libXXX.so` need to be in the `lib/` directory, and the plugins `VCGXXXX.so` in the `lib/plugins/` directory. If done correctly, the plugins are loaded automatically.

Thank you for your reply and sorry for the trouble @lhofmann. I did as you said. I even followed the “Archive” instruction on the website which has the plugins and libs in the correct directory, yet I still don’t see the plugins when I open the ParaView. I cannot load them manually either, I get this error:

> libOpenGL.so.0: cannot open shared object file: No such file or directory  
> ERROR: In /home/buildslave/dashboards/buildbot/paraview-pvbinsdash-linux-shared-release\_superbuild/build/superbuild/paraview/src/ParaViewCore/ClientServerCore/Core/vtkPVPluginLoader.cxx, line 403  
> vtkPVPluginLoader (0x7f617000cf10): libOpenGL.so.0: cannot open shared object file: No such file or directory

I’ll try to see if I can install it using the “Debian Package VCGParaView” instruction.

You could try installing the libopengl0 package: `sudo apt install libopengl0`

Thank you @lhofmann. Installing the libopengl0 solved it. I really appreciate your help. 🙂

Hi @lhofmann  
I am trying to solve ftle field for some complex 3d geometries. Are these paraview plugins able to calculate ftle in 3d complex shapes? or are they just for simple 2d shapes? I highly appreciate your answer on this. Thanks a lot in advance.
