# cov_build.sh - Coverity-friendly build of networkmanager with the Gnome
# libnm proxy.
#
# This is the second half of the original cov_build.sh: it builds only the
# networkmanager component. The Thunder ecosystem and mock dependency files
# it relies on are produced by build_dependencies.sh, which must be run first
# from the same workspace.
#
# Usage:
#   ./build_dependencies.sh
#   ./cov_build.sh
#
# Override any of the environment variables below on the command line, e.g.:
#   THUNDER_REF=R4.4.3 ./cov_build.sh
#

# Re-exec under bash if started with a non-bash shell (e.g. `sh cov_build.sh`,
# where sh is dash). This script relies on bash features such as `pipefail`
# and ${BASH_SOURCE[0]}, which dash does not support.
if [ -z "${BASH_VERSION:-}" ]; then
  exec bash "$0" "$@"
