arx-arrowcpp-sources 24.0.0

Bundled Apache Arrow C++ source release for the Arx ecosystem

arx-arrowcpp-sources

arx-arrowcpp-sources packages a pinned Apache Arrow C++ source release for the Arx ecosystem.

It does not ship compiled Arrow binaries. Instead, it ships:

• the upstream Apache Arrow cpp/ source tree
• the upstream Apache Arrow format/ FlatBuffers definitions used by C++
• upstream release metadata, license, and notice files
• Python helper functions to locate those files from build systems

The package also depends on pyarrow >=24.0.0,<25.0.0 so Arx projects can use the matching Python runtime package alongside the vendored source-release layout.

Should you bundle Arrow C++ sources?

Usually, no. Prefer these integration paths when possible:

• Use an installed Arrow C++ package with CMake's find_package(Arrow REQUIRED) and link Arrow::arrow_shared or Arrow::arrow_static.
• Use pkg-config --cflags --libs arrow for non-CMake native builds.
• For Python-extension builds, use pyarrow.get_include(), pyarrow.get_libraries(), and pyarrow.get_library_dirs().

This package exists for Arx workflows that need a reproducible, Python-package addressable copy of the Arrow C++ source release.

Usage

from arx_arrowcpp_sources import (
    bundled_arrowcpp_version,
    get_cmake_dir,
    get_cpp_dir,
    get_header_files,
    get_include_dir,
    get_source_files,
)

print(bundled_arrowcpp_version())
print(get_cpp_dir())
print(get_include_dir())
print(get_cmake_dir())
print(get_header_files())
print(get_source_files())

Build behavior

Run python scripts/build_bundle.py before poetry build. The bundle script fetches the pinned Apache Arrow source release, verifies its SHA256 checksum, and stores the C++ source subset under src/arx_arrowcpp_sources/vendor/.

The vendored layout is intentionally close to the upstream release layout:

src/arx_arrowcpp_sources/vendor/
