Following this link, it says "Make output python3-compatible". So it still run
under 2.x but generate codes for 3.x:-(
After taking Chris's suggestion, the installation is pushing forward a little
and then bump into another error:
----------
File "D:\Patch\ctypesgen-master\ctypesgencore\parser\pplexer.py", line 123, in
punctuator_regex
punctuator_regexes.sort(lambda a, b: -cmp(len(a), len(b)))
TypeError: must use keyword argument for key function
----------
This error has been mentioned in "Sorting HOW TO" section in 3.4 document,
"In Py3.0, the cmp parameter was removed entirely"
"To convert to a key function, just wrap the old comparison function:"
"In Python 3.2, the functools.cmp_to_key() function was added to the
functools module in the standard library."
Oh, goodness! do I have to dive into 2.x?
Based on the assumptions below:
1. It might be not easy to upgrade it to 3.x (at least not just run 2To3), or
else its author will not drop it.
2. I have to go back into 2.x jungle to study all these difference.
3. Even "Python setup.py install" passed, it's still not sure if the output
will be correct.
I think it's better to drop it too. Thanks for your advice, Chris and Peter.
