# Build manylinux1 wheels for pysam. Based on the example at
# <https://github.com/pypa/python-manylinux-demo>
#
# It is best to run this in a fresh clone of the repository!
#
# Run this within the repository root:
#   docker run --rm -v $(pwd):/io quay.io/pypa/manylinux1_x86_64 /io/buildwheels.sh
#
# The wheels will be put into the wheelhouse/ subdirectory.
#
# For interactive tests:
#   docker run -it -v $(pwd):/io quay.io/pypa/manylinux1_x86_64 /bin/bash

set -xeuo pipefail

# For convenience, if this script is called from outside of a docker container,
# it starts a container and runs itself inside of it.
if ! grep -q docker /proc/1/cgroup; then
  # We are not inside a container
  exec docker run --rm -v $(pwd):/io quay.io/pypa/manylinux1_x86_64 /io/$0

# Bundle external shared libraries into the wheels
#
# The '-L .' option is a workaround. By default, auditwheel puts all external
# libraries (.so files) into a .libs directory and sets the RUNPATH to $ORIGIN/.libs.
# When HTSLIB_MODE is 'shared' (now the default), then all so libraries part of
# pysam require that RUNPATH is set to $ORIGIN (without the .libs). It seems
# auditwheel overwrites $ORIGIN with $ORIGIN/.libs. This workaround makes
# auditwheel set the RUNPATH to "$ORIGIN/." and it will work as desired.
