I try to test this package but with no luck. This module was written for Python 2.x but mine is 3.4 so I use the 2To3 to "upgrade" it first (it seems OK). Then I run "python setup.py install" and get the following error:
   ...
   ...
   File "D:\Patch\ctypesgen-master\ctypesgencore\parser\lex.py", line 41, in <module>
    _INSTANCETYPE = types.InstanceType
   AttributeError: 'module' object has no attribute 'InstanceType'

Below is the troubled codes in file lex.py:
Note: In original codes (before 2To3 modify), there is "types.ObjectType" instead of "object".
---------
# Available instance types.  This is used when lexers are defined by a class.
# It's a little funky because I want to preserve backwards compatibility
# with Python 2.0 where types.ObjectType is undefined.
try:
    _INSTANCETYPE = (types.InstanceType, object)
except AttributeError:
    _INSTANCETYPE = types.InstanceType
    class object: pass   # Note: needed if no new-style classes present 
-----------
The author had put some comments above these codes but I have no idea what he is talking about.

There is someone who had encountered the same problem last year and raise a question at its home page, but the author seems has no interest on doing anything on it anymore.
https://github.com/davidjamesca/ctypesgen/issues/53

Does anyone know how to fix it? or the whole job will be a mission impossible if no help from its author?
