Hello. Sorry for posting in the dev mailing list, I did not found an user list
for Pypy.
I developed a C extension for CPython 3.6+. This extension uses
PyDictKeysObject. I tried to enable Pypy in cibuildwheel, but I get a
compilation error for PyDictKeysObject.
What object can be used by C extension in Pypy instead of PyDictKeysObject?
This is the correct place to post, welcome. PyDictKeysObject is a
CPython implementation detail, and not meant to be used even with
CPython. The declaration is found in the cpython/Include/cpython/
directory. In general, we would recommend not writing c-extension
modules for PyPy, rather providing a pure python version of your library
since in 99% of cases it will be faster than going through the C-API
emulation [0]. If you really have to use C, we would recommend you use
CFFI [1] or CPPYY [2].
