This is essentially the same as my post on ask.sagemath.org
<https://ask.sagemath.org/question/64760/cython-compilation-fail-after-separating-code/>,
but after a while with no comments, I figured it would be okay to get more
eyes on it here. I also asked on Zulip, but no dice there either.
It would be a bit redundant of me to copy+paste the entire post, so I will
give a brief summary. To view more details, please refer to the linked post
above. I can certainly provide anything else that is needed as well.
------------------------------------------------------------------------------------------------------------------------
In short, I had a huge file that had all of my code in it. In this file, I
used the *sage.data_structures.bitset* and
*sage.data_structures.bitset_base* modules. When I tried to compile this
(aptly named) ginormous file, the compilation succeeded and I was able to
instantiate all classes and call all functions in this file.
However, I tried doing some code cleanup and tried separating the code into
logical modules. When doing so, I got some confusing compilation errors.
Here is just the first, but again, please refer to the linked
ask.sagemath.org post above for the entire output:

I am by no means a Cython expert so I am quite stuck here. If anyone has
ideas to remediate this, please let me know.
Thank you!
