# Minimal CI image for running x86-64 MR smoke tests (Ubuntu 24.04).
# Test-only: no compilers. Binaries are cross-compiled on arm64 runners
# using ubuntu-24.04-arm64-smoketest-build and transferred as artifacts.
#
# Packages:
#   cmake     - provides ctest
#   xsltproc  - converts CTest XML to JUnit in test.linux.after_script.sh
#   libgomp1  - OpenMP runtime for test binaries (libstdc++6/libgcc-s1
#               are already present in the Ubuntu 24.04 base image)
#   python3   - drives the test pass cache (ci/scripts/test_cache.py)
#
# Rebuild and push when this file changes:
#   docker buildx build --platform linux/amd64 \
#     -t registry.gitlab.com/libeigen/eigen/ubuntu-24.04-amd64-smoketest-run:latest \
#     --push ci/docker/ubuntu-24.04-amd64-smoketest-run/
