[vtkusers] Build VTK 8.1.1 on Windows vc12 - vtkPythonArgs.cxx Line 105 Error cannot convert from 'const char *' to 'char *

[David Gobbi]

It looks like the Python folks changed the PyUnicode_AsUTF8() function in
Python 3.7.  This function used to return "char *" but in 3.7 it returns
"const char *".

I'll start working on a patch for the VTK master branch, but for now your
best option is to use Python 3.6.
