[OpenSource-Edge-for-IBM-Tool-1]

Distro Owner PR Review Checklist

• Confirm that PACKAGE_URL points to the correct source — it should be a GitHub repository link. If not, identify the correct GitHub source and update the build script accordingly (follow the steps provided in the PR Validation Process).
  Note: PACKAGE_URL should never be a .tar archive link.
• Confirm that the PACKAGE_VERSION matches the version required by your project.
• Check if any additional configuration is needed to install the package from source that is not present in the current PR.
• Optionally, validate the script using the steps outlined below.

PR Validation Process

• Use a ppc64le VM with at least 8 GB RAM (more is recommended, as insufficient RAM may cause random build failures).

• Run the <package-name>.sh script provided in this PR inside a fresh UBI 9.3 container (i.e., sh <package-name>.sh).

• Ensure that the build script execution ends with a message like:
  "Pass | Both_Install_and_Test_Success"

• If the build script fails and you identify a fix required in the <package-name>.sh script to achieve successful execution, follow these steps:

  • Fork the build-scripts repo
  • Create a new branch for your changes, starting from the version proposed in this PR
  • Follow all the points mentioned in CONTRIBUTING.MD before raising the PR
  • Open a new PR from your fork with the fix
  • Close this auto-generated PR and include a link to your updated PR in the closure comment
