Highlights
- Fully automated CI/CD pipelines build and unit-test every package.
- Rigorous validation on:
• 20 real machines
• 79 Docker images
• 1 Android x64 emulator - Coverage for Windows, Linux (glibc & musl), macOS, and Android.
Platform notes
Windows
• Use win-x64 or win-x86 for mainstream desktops/servers (tested on Windows Server 2022 & 2025).
• win-arm64 now available for Windows on ARM devices.
Linux (glibc)
• centos.7-* – built with GCC 4.8.5 + compatibility patches. Runs on glibc 2.17+ (CentOS 7, RHEL7, Debian 8, Ubuntu 14.04 …).
• linux-* – built with GCC 8.5.0, no code patches, glibc 2.28+ (RHEL8+, Debian10+, Ubuntu20.04+, openEuler 20.03-LTS, Deepin …). Recommended for most users.
• ubuntu.22.04-* – built with GCC 11.2.0, for Ubuntu 22.04 / Debian11 / RHEL9+. Fewer target OSes; may be removed in future releases.
Linux (musl)
• linux-musl-* – built on Alpine 3.22, fully statically linked against libstdc++ & libgcc. Zero runtime deps; tested down to Alpine 3.12 (musl 1.1.24). Works even on OpenWRT routers!
Android
• android-* – built with NDK r27, API 24, statically linked libstdc++. Runs on Android 7.0 (Nougat) and newer.
macOS
• osx-x64 and osx-arm64 support Intel Macs and Apple-silicon (M1–M4) Macs respectively.
Packages no longer published
• ubuntu.24.04-* – superseded by linux-* / ubuntu.22.04-*
• win11-x64 – superseded by win-x64
• osx.15-arm64 – superseded by osx-arm64
• Planned but cancelled: rhel9-* (use linux-* instead)
