Error compiling Cython file: EnumType problem

[slonik]

Hey Everyone,

I am trying to install a very popular NLP (Natural Language Processing) cython-based package spacy: https://github.com/spacy-io/spaCy

and run into a cython compilation problem with both recent cython versions 0.24.1 and 0.24 

$ cython --cplus -o gold.cpp gold.pyx

results in the following error trace:

Error compiling Cython file:

------------------------------------------------------------

...

cdef dict __Pyx_globals = globals()

if PY_VERSION_HEX >= 0x03040000:

                 ^

------------------------------------------------------------

EnumType:51:18: undeclared name not builtin: PY_VERSION_HEX

Error compiling Cython file:

------------------------------------------------------------

...

cdef dict __Pyx_globals = globals()

if PY_VERSION_HEX >= 0x03040000:

    symbol_t = __Pyx_EnumBase('symbol_t', __Pyx_OrderedDict([

                            ^

------------------------------------------------------------

EnumType:53:29: undeclared name not builtin: __Pyx_EnumBase

and so on. It guess it has something to do with cpdef enum definitions and the source file Cython/Utility/CpdefEnums.pyx

Is there a solution or a workaround? Right now I seem to be stuck.

Yes, indeed it looks similar. So, it means that it is not just my problem :-) However, there is no solution or workaround posted for the issue. Any help is greatly appreciated.
