# Build Python-agnostic ray-cpp wheel.
#
# The ray-cpp wheel contains only C++ headers, libraries, and executables
# with no Python version-specific content. This script builds a single wheel
# tagged py3-none-manylinux2014_* that works with any Python 3 version.
#
# Usage: ./ci/build/build-cpp-wheel.sh
#
# Environment variables:
# BUILDKITE_COMMIT - Git commit SHA for ray.__commit__ (required)
set -exuo pipefail
TRAVIS_COMMIT="${TRAVIS_COMMIT:-$BUILDKITE_COMMIT}"
# Use any Python 3 to run setuptools (wheel content is Python-agnostic)
PYTHON="cp310-cp310"
