I build latest head of paraview-superbuild with Python enabled and
USE_SYSTEM_PYTHON=OFF on a openSUSE Tumbleweed system
I get the following error

To my knowledge one need to decide if Python is compiled with 16 or 32 bit
encoding,
on my system I have 32 bit:
/usr/bin/python2
Python 2.7.14 (default, Oct 12 2017, 15:50:02) [GCC] on linux2
Type "help", "copyright", "credits" or "license" for more information.
import sys
print(sys.maxunicode)
1114111
When I try the Python built from PV, it has 16 bits:
/home/fwein/code/cfs_paraview/build_python/build/superbuild/python/build/python
Python 2.7.14 (default, Feb 2 2018, 15:33:16)
[GCC 7.3.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
import sys
print(sys.maxunicode)
65535
So the mixing from own built python and system python makes problems.
Is this mixing a bug?
Currently, I don't need python in PV, and for my colleague SYSTEM_PYTHON
worked. So just to let you know.
BTW, what is the status with python3?
