Yes, my extension needs dictobject.
Are you sure that you really need Py_BUILD_CORE? Here's what the code has to say about it: https://github.com/python/cpython/blob/main/Include/pyport.h#L17 Py_BUILD_CORE: Build Python core. Give access to Python internals, but should not be used by third-party modules. If your extension truly needs to reach into the internals of CPython, then you're going to have to figure a lot of things out for yourself, including how to make sure it works on every platform. A more productive approach would be to stick to the actual API: https://docs.python.org/3/c-api/stable.html What is it that doesn't work without Py_BUILD_CORE?
