# Run this script on a machine with Clang 18 and Rust 1.81. These versions both
# use LLVM 18; matching LLVM versions are required for grcov to produce
# a report across the entire codebase.
#
# One can prepare such environment with Docker:
#
# docker build \
# --build-arg rust_version=1.81 \
# --build-arg cxx_package='clang-18 libclang-rt-18-dev' \
# --build-arg cxx=clang++-18 \
# --build-arg cc=clang-18 \
# --tag=newsboat-clang-18-rust-1.82:24.04 \
# --file=docker/ubuntu_24.04-build-tools.dockerfile \
# docker
#
# docker run \
# -it --rm \
# --mount type=bind,source=$(pwd),target=/workspace -w /workspace \
# --user $(id -u):$(id -g) \
# newsboat-clang-18-rust-1.81:24.04 \
