Error Running Example Code

[Seth-Harlaar]

I managed to get to the point of successfully compiled the example code. Then I get to running the example with 'python program.py' and I get an error:

Traceback (most recent call last):
  File "program.py", line 5, in <module>
    lib = cdll.LoadLibrary("./libffi-example.so")
  File "/usr/lib/python2.7/ctypes/__init__.py", line 444, in LoadLibrary
    return self._dlltype(name)
  File "/usr/lib/python2.7/ctypes/__init__.py", line 366, in __init__
    self._handle = _dlopen(self._name, mode)
OSError: /usr/lib/ghc/ghc-prim-0.5.2.0/libHSghc-prim-0.5.2.0-ghc8.4.4.so: undefined symbol: stg_gc_unpt_r1

I'm not sure what stg_gc_unpt_r1 is, and what to do about it. I do not have a tonne of expereince with python, but have to do some work with it and I want to get this example working.
I compiled everything on WSL because windows does not support dynamic linking. If there is any information that could help me, that would be great.
