[Python] Error compiling Cython files on Windows during release verification #40375
Description
Describe the bug, including details regarding any error messages, version, and platform.
I ran into this while doing release verification for 15.0.1 RC0. The code in the error message is relatively new (PyCapsule) but old enough that it may just be my setup.
On Windows 11 in cmd.exe prompt with Anaconda set up, I ran
dev\release\verify-release-candidate.bat 15.0.1 0C++ compiled fine and then when it got to building PyArrow, I see:
-- Running cmake --build for PyArrow
cmake --build . --config release
