Hello,
I create Flatpak for Paraview. 
Flatpak is a packaging and distributing desktop software on Linux.
I would like it to be submit to Flathub, an app store for Flatpak apps. Many Linux distros supported Flatpak. So I think it would be beneficial to package large software like Paraview into Flatpak, it will make installing quick and easy.
  
  
    
  Find and install hundreds of apps and games for Linux. Enjoy Firefox, Telegram, RetroArch, GIMP and many more!
   
  
    
    
  
  
 
This is what I have been working on so far.
I does build and runใ 
I encounter a graphical issue. The graph show checker pattern glitch. 
                        
               
             
I encounter this glitch with Tomviz as well. So I think this might be issue with the display backend and Flatpak. Do anybody know what it is?

    Hello,
I am trying to create Flatpak package for Tomviz and upload to Flathub… .

And finally Tomviz build with cmake from github.com/OpenChemistry/tomviz tag:1.9.0 commit: b397df6d40810b97ad3afa221c2fa3e027d20754
` - -DCMAKE_BUILD_TYPE:STRING=RelWithDebInfo`
During building of Tomviz, I got this error.

I suspect that I use OpenChemistry/ParaView version 5.9.0 (commit: 0aaf903ba3e8d012a608a466f798a041b4aebe17) instead of the commit: 98a2eea1af02a45fa6d9b72b97b67f991bcb1f0e (reference in superbuild) , that might fix this issue? 
I will try rebuilding with the commit reference in superbuild (https://github.com/OpenChemistry/tomvizsuper), but it will take very long time to compile again.

I also think that this might cause by my outdate graphics driver. 
Other problem I have is missing Examples and no matplotlib support. 
If anybody is interest, please build Paraview Flatpak and try it out.
To build Paraview Flatpak.
Create new working folder. 
Install flatpak-builder, for Ubuntu, sudo apt install flatpak-builder 
Install KDE Sdk, choose version 5.15 (system), flatpak install org.kde.Platform org.kde.Sdk io.qt.qtwebengine.BaseApp 
Clone sub-modules, these sub-modules are pre-made Flatpak manifest that commonly use, we will be using glew, git clone git://github.com/flathub/shared-modules.git 
Download org.paraview.Paraview.yaml and tbb_cmake.patch from my github repo, put them in same folder. 
flatpak-builder --install --user build org.paraview.Paraview.yaml --force-clean 
Wait until finish and run with, flatpak run org.paraview.Paraview 
 
Let me know if it work.
             
            
               
               
               
            
                
            
           
          
            
            
              Anyone know where am I support to put the example data?
