p-vdp opened a new issue, #47823: URL: https://github.com/apache/arrow/issues/47823
### Describe the bug, including details regarding any error messages, version, and platform. [Python v3.15.0a1](https://github.com/python/cpython/releases/tag/v3.15.0a1) is out, and after building it from source I'm trying to build `pyarrow` from [apache-arrow-22.0.0-rc0](https://github.com/apache/arrow/releases/tag/apache-arrow-22.0.0-rc0). I'm following the same steps to build `pyarrow` that I've used successfully on Python 3.14.0. Here's the error output: ```shell 234.8 /root/builds/arrow/python/pyarrow/src/arrow/python/extension_type.cc: 234.8 In member function ‘PyObject* arrow::py::PyExtensionType::GetInstance() 234.8 const’: 234.8 /root/builds/arrow/python/pyarrow/src/arrow/python/extension_type.cc:167:20: 234.8 error: ‘PyWeakref_GET_OBJECT’ was not declared in this scope 234.8 167 | PyObject* inst = PyWeakref_GET_OBJECT(type_instance_.obj()); 234.8 | ^~~~~~~~~~~~~~~~~~~~ 234.8 gmake[2]: *** [CMakeFiles/arrow_python.dir/build.make:160: 234.8 CMakeFiles/arrow_python.dir/pyarrow/src/arrow/python/extension_type.cc.o] 234.8 Error 1 234.8 gmake[2]: *** Waiting for unfinished jobs.... 234.8 gmake[1]: *** [CMakeFiles/Makefile2:126: 234.8 CMakeFiles/arrow_python.dir/all] Error 2 234.8 gmake: *** [Makefile:136: all] Error 2 234.8 error: command '/usr/bin/cmake' failed with exit code 2 ``` ### Component(s) Python -- This is an automated message from the Apache Git Service.
