Metabolomics Software Build Reproducibility

metabolomics-software-build-reproducibility

Summary

Establish and maintain reproducible automated build pipelines for metabolomics analysis software across multiple platforms (macOS, Windows, Linux) using containerized CI/CD environments. This skill ensures that metabolomics tools like Maven GUI can be reliably compiled, packaged, and distributed with consistent dependency resolution and executable artifacts.

When to use

When developing or maintaining a multi-platform metabolomics GUI tool (such as Maven GUI) that must produce binary executables for end users, and you need to ensure that builds are reproducible across different OS platforms, dependency versions are pinned and tracked, and release artifacts are automatically generated without manual compilation steps on each developer's machine.

When NOT to use

• If the metabolomics software is pure Python, R, or another interpreted language with no compiled components — containerized package distribution (conda, pip, CRAN) may be simpler than binary CI/CD.
• If you only need to build for a single target platform — simpler local or single-platform CI/CD may suffice; multi-platform orchestration introduces complexity.
• If the metabolomics tool has no external GUI or binary distribution requirement (e.g., a command-line-only or web-hosted service) — this skill is specific to desktop GUI applications with downloadable executables.

Inputs

• Git repository (eugenemel/maven or similar metabolomics tool source)
• Build configuration files (build.pro for qmake, INSTALL_ROOT settings, platform-specific make_dist scripts)
• Dependency specification (Qt5 version, zlib, sqlite3, etc.)
• CI/CD pipeline configuration (appveyor.yml, .travis.yml, or equivalent)

Outputs

• Platform-specific executable binaries (maven_dev_*.exe for Windows, Maven.app bundle for macOS, AppImage or tarball for Linux)
• CI/CD build logs and status reports (pass/fail, artifact URLs)
• Release artifacts published to GitHub Releases or equivalent distribution channel
• Dependency lock files or pin specifications captured in CI/CD configuration

How to apply

Set up platform-specific CI/CD jobs (e.g. Appveyor for Windows and macOS, Travis for Linux) that clone the repository recursively, install pinned versions of build dependencies (Qt5, qmake, make, gcc/clang via package managers like MSYS2 on Windows or Homebrew on macOS), configure the build with qmake -r build.pro, compile with make -j4 using parallel jobs, and generate distributable packages by running make INSTALL_ROOT=appdir install followed by platform-specific packaging scripts (make_dist_win32.sh, make_dist_osx.sh, make_dist_linux.sh). Verify that CI/CD logs confirm successful compilation, linking, and artifact generation (e.g., maven_dev_*.exe for Windows or Maven.app for macOS). Monitor CI/CD platform dashboards to confirm all matrix configurations pass before tagging a release.

Examples

git clone --recursive [redacted-email]:eugenemel/maven.git maven && cd maven && qmake -r build.pro && make -j4 && make INSTALL_ROOT=appdir install && ./make_dist_osx.sh

Evaluation signals

• CI/CD build status is reported as 'passed' for all targeted platforms (Windows and macOS as of November 2024) in Appveyor dashboard or equivalent.
• Binary artifacts (maven_dev_*.exe, Maven.app) are successfully generated and appear in CI/CD artifact logs with expected file sizes and timestamps.
• Executable binaries can be launched on target OS without missing library errors or unresolved symbols, indicating correct dependency linking.
• Release tag in git matches corresponding GitHub Release entry with downloadable executable artifacts attached.
• Build logs show no compiler warnings (or only expected/suppressed warnings), no linking failures, and successful completion of all qmake, make, and packaging steps.

Limitations

• As of November 2024, Linux builds have been retired from the automated pipeline — the skill as documented now covers only Windows and macOS; practitioners needing Linux support must maintain a separate build environment or restore Travis CI configuration.
• CI/CD platforms (Appveyor, Travis) require authentication and may have rate limits, cost, or service disruptions — a single platform outage can block releases.
• Qt5 version pinning and MSYS2/Homebrew package versions can drift or become unavailable; periodic maintenance of dependency specifications is required to keep builds reproducible over time.
• Platform-specific packaging scripts (make_dist_*.sh) must be manually maintained for each new target OS or significant build environment change; errors in packaging scripts can produce invalid or incomplete executables despite successful compilation.
