HI, I am new to Catalyst, I have installed the paraview from source code with

cmake -DBUILD\_EXAMPLES:BOOL=ON -DPARAVIEW\_ENABLE\_PYTHON:BOOL=ON -DPARAVIEW\_ENABLE\_CATALYST:BOOL=ON -DPARAVIEW\_BUILD\_CATALYST\_ADAPTORS:BOOL=ON -DPARAVIEW\_USE\_MPI:BOOL=ON -DPARAVIEW\_INSTALL\_DEVELOPMENT\_FILE  
S:BOOL=ON -DCMAKE\_INSTALL\_PREFIX=/home/dmu/Tools/Paraview-V5.6 …

After the installation, I can find the “vtkCPProcessor.h” in “/home/dmu/Tools/Paraview-V5.6/include/paraview-5.6”, However, I can not find the library file like “libvtkCPProcessor.so” in “/home/dmu/Tools/Paraview-V5.6/lib”.

Could someone guide me where to find this library or tell me what I did wrong, please?

Hi,

vtkCPProcessor.cxx is defined in libvtkPVCatalyst.so module.

Best,
