Joris Van den Bossche created ARROW-18340:
---------------------------------------------
Summary: [Python] PyArrow C++ header files no longer always
included in installed pyarrow
Key: ARROW-18340
URL: https://issues.apache.org/jira/browse/ARROW-18340
Project: Apache Arrow
Issue Type: Improvement
Reporter: Joris Van den Bossche
Assignee: Alenka Frim
Fix For: 10.0.1
We have a python build env var to control whether the Arrow C++ header files
are included in the python package or not
({{PYARROW_BUNDLE_ARROW_CPP_HEADERS}}). This is set to True by default, and
only in the conda recipe set to False.
After the cmake refactor, the Python C++ header files no longer live in the
Arrow C++ package, and so should _always_ be included in the python package,
regardless of how arrow-cpp is installed.
Initially this was done, but it seems that
https://github.com/apache/arrow/pull/13892 removed this unconditional copy of
the PyArrow header files to {{pyarrow/include}}. Now it is only copied if
{{PYARROW_BUNDLE_ARROW_CPP_HEADERS}} is enabled.
