# Simple script to test a build of all supported targets.
# To build multi-arch, QEMU can be used and ideally buildkit support in Docker.
#
# Follow the relevant instructions to do this for your OS, e.g. for Ubuntu it may be:
# $ sudo apt-get install qemu binfmt-support qemu-user-static # Install the qemu packages
# $ docker run --rm --privileged multiarch/qemu-user-static --reset -p yes
# Confirm you can run a non-native architecture image, e.g.:
# $ docker run --rm -t arm64v8/ubuntu uname -m # Run an executable made for aarch64 on x86_64
# WARNING: The requested image's platform (linux/arm64/v8) does not match the detected host platform (linux/amd64) and no specific platform was requested
# aarch64
#

# The local file with all the supported build configs in

# Output checks are easier plus do not want to fill up git
PACKAGING_OUTPUT_DIR=${PACKAGING_OUTPUT_DIR:-test}
echo "Cleaning any existing output"
rm -rf "${PACKAGING_OUTPUT_DIR:?}/*"

# Iterate over each target and attempt to build it.
# Verify that an RPM or DEB is created.
