HI, I am new to paraview, I have installed the paraview from source code.
When i building the examples in Calalyst, error had occurred:
When i set “USE\_CATALYST” off, the error was gone.
I have downloaded the code “Catalyst-v5.6.0-RC2-Base-Enable-Python-Essentials-Extras-Rendering-Base”, but i don’t know how to use it.
I have used cmake to configure it ,but error had occurred:
Could someone guide me how to use catalyst code?
thanks

Hi,
how did you build your ParaView ? I mean, how do you configure CMake for the build ?
It looks like some needed module were not build in paraview.
If you may share your CMakeCache.txt, it can be usefull.
