When running the notebook it gets as far as the section:

ctypes - Preparing the C library

whereupon I get the following:

---------------------------------------------------------------------------
ValueError                                Traceback (most recent call last)
<ipython-input-10-684349b68d2d> in <module>()
      5 
      6 # These variables, defined inside the C library, are readonly.

      8 cstdout = FILE_p.in_dll(libc, 'stdout')
      9 cstderr = FILE_p.in_dll(libc, 'stderr')

ValueError: dlsym(0x11b5c0e50, stdin): symbol not found
