'unknown type name' error while using Cython to generate C code

Question

I have successfully generated .c file using Cython, but when i try to compile it using gcc, i get these errors... This is just the first line of the error... There are 3 pages of errors similar to this... My .py code is a simple:

print "test"

error:

unknown type name ‘Py_UNICODE’
static CYTHON_INLINE size_t __Pyx_Py_UNICODE_strlen(const Py_UNICODE *u)

PyPy is a JIT. It does not generate C code. What makes you think PyPy can do this for you? — Uli Köhler

I have been experimenting with cython and pypy, and it seems i have mistaken pypy for cython... — user1176999

Modifying the question this extensively does no one any favors. If you have a new question, ask a new question. — Ignacio Vazquez-Abrams

@IgnacioVazquez-Abrams You have alot of SO reputation. Do you think this is a case for a rollback? — Uli Köhler

See this mailing list post.

Citing it:

Cython is not a Python to C compiler in the sense that it does away
with the Python interpreter/runtime, rather it creates .c files that
are compiled against the Python/C API and can be loaded into a running
session.

See this list of interpreters which lists some compilers that might be useful to you!

For a guide to compilation, also have a look at the compilation page of the Cython wiki

Sure, but why can't it leave the intermediate .c file regardless?

@IgnacioVazquez-Abrams It is indeed possible to compile to C, once you get a .pyx file, see docs.cython.org/src/reference/language_basics.html
