Cmake error

[Tushar Athawale]

Hi,

I am tying to install topology toolkit ttk-0.9.9 on macOS Big Sur and trying to compile it against Paraview-v5.8.1. When I try to configure Paraview with ccmake, I am getting the following error:

-- Could NOT find Python3 (missing: Python3_LIBRARIES Python3_INCLUDE_DIRS Development) (Required is at least version "3.2")
CMake Error at VTK/CMake/vtkModule.cmake:4112 (message):
Could not find the Python3 external dependency.
Call Stack (most recent call first):
VTK/Utilities/Python/CMakeLists.txt:46 (vtk_module_find_package)

Could you please help me resolve this error?

Thanks,

Tushar

Dear Tushar,

Which python is installed on your system ? Can you give us the output of "python --version" ?

Is there anything special with your python like a virtual environment?

Best,

Charles

Dear Charles,

Thanks for looking into this. The output of "python --version" on my system is "Python 3.9.12". Also, I am currently not using any virtual environment.
The following link contains thread discussing a similar issue, but I could not understand their solution:

Thanks,

It seems your python is too recent compared to the ParaView version you are trying to use. I can help you to make it work but first I would like to know: is there any reason you use an old ParaView / TTK ? You may want to use ParaView 5.10 with the latest TTK version. (The ParaView release on https://www.paraview.org/download/ already contains TTK).

Best,

Charles

Dear Charles,

Thanks very much! I did not know that Paraview latest version already comes with TTK as plugin. I am now able to get TTK filters working with the Paraview latest release.

Thanks again for helping me resolve the issue.

Best,

Tushar
