# Cygwin build inputs and matching source for Windows voice By Steven Van · 2026-09-10 These CI-only archives aren't part of Codex's user packages; they cover 103 pinned binary packages and 83 matching sources for Cygwin licensing compliance. Codex has [published the Cygwin build inputs and matching source code]() behind the native Windows voice feature in [Codex](), to meet Cygwin's licensing terms. The archives are CI-only: they support how the Windows voice builds are produced and are not included in the packages Codex users install. - **cygwin-build-inputs.tar.gz**: 103 pinned Cygwin binary packages and the signed package index used by the offline build installer. - **cygwin-build-sources.tar**: the 83 corresponding source package archives at the exact versions named in that index, including the upstream source, patches, and build recipes from Cygwin's -src packages. - **cygwin-source-map.json**: maps each selected binary package to its source archive, with the source size and SHA-512 digest from the pinned index. - **CYGWIN-SOURCE-NOTICE.txt**: a source access and licensing notice. The SHA-256 pins for both archives are kept in .github/scripts/voice-cygwin-snapshot.json in the Codex repository. Licensing terms are set by Cygwin and vary by package; Codex points to Cygwin's own licensing page and the individual source and binary archives for the specifics.
