Fedora 43 KDE GitHub Actions RPM Builder

This repository is a static GitHub Actions input repo for rebuilding Fedora 43 KDE packages from Fedora dist-git with x86-64-v4 code generation and -O3 optimization.

What Is Checked In

• Fedora 43 KDE binary package manifest: binary-packages.txt
• Fedora 43 source package manifest: source-packages.txt
• Binary to source mapping: source-map.tsv
• A reference macro RPM spec showing the intended RPM flag override: custom-macros.spec
• On-demand GitHub Actions workflow: build-fedora-rpms.yml

The checked-in manifests currently cover:

• 342 Fedora 43 binary packages
• 265 Fedora 43 source packages

Build Model

The workflow does not use COPR. It does this instead:

1. Reads package selections from the checked-in source manifest or from a manual dispatch input.
2. Clones each selected Fedora dist-git repository from src.fedoraproject.org.
3. Fetches source tarballs from Fedora lookaside using fedpkg sources.
4. Installs BuildRequires with dnf builddep.
5. Rebuilds the package with RPM macros overriding %optflags to: -O3 -march=x86-64-v4
6. Uploads the built .rpm and .src.rpm files as GitHub Actions artifacts.

Using The Workflow

Run the Build Fedora RPMs workflow manually with workflow_dispatch.

You can:

• build a specific list of source packages
• provide binary package names and have them mapped to source packages
• build a chunk from the checked-in manifest by batch_index and batch_size

This is important because GitHub Actions matrix jobs are capped, and the full Fedora 43 KDE source manifest contains 265 packages.

Practical Notes

• The workflow is intended for on-demand rebuilds, not for one-click rebuilding of the full KDE stack in a single run.
• Some packages may still fail in GitHub Actions because Fedora package builds can rely on environment assumptions that are easier to satisfy in Koji or COPR than in a generic CI runner.
• If you want to rebuild the whole stack, dispatch the workflow in batches.
