[vtkusers] Compiling VTK Python from source

Sun Mar 11 21:15:34 EDT 2018

It seems I was a bit premature in jumping to the conclusion that my VTK
installation was complete :-). Yes I did generate a vtkpython.exe but that
was with the 2.7.0 installation. When I did run this with Python3.5 I got
an error.

So I went back to the build process specifically cmake and these are the
errors I got when I typed make -j8

This is my cmake command -

cmake ../ -DBUILD_SHARED_LIBS=ON -DBUILD_TESTING=ON
-DCMAKE_BUILD_TYPE=Release -DVTK_WRAP_PYTHON=ON
-DVTK_PYTHON_VERSION=3.5 -DPYTHON_EXECUTABLE=/usr/bin/python3.5
-DPYTHON_INCLUDE_DIR=/usr/include/python3.5
-DPYTHON_LIBRARY_PATH=/usr/lib/python3.5

I presume VTK can be compiled with Python 3.5 or not ? I am not sure.
Apologies for the earlier over sight. This is on Ubuntu 16.04.
