Mini runtime that suitable for model inference in server, only core, imgproc, imgcodec modules was built.

Packages are all built & integration-tested by a fully automated CI/CD pipeline on GitHub, CICD code fully open source.

• 20 native OS installations
• 79 Docker containers
• Android-x64 emulator

Assurance: every package runs reliably on its target platform.

• Use win-x64 (most PCs) or win-x86 (legacy).
• Tested on Windows Server 2022 & 2025; older versions should work thanks to Windows’ strong ABI compatibility.
• win-arm64 is now available and verified for Windows on ARM devices.

Three flavours, each shipping x64 & arm64 artifacts and dynamically linking libstdc++.so.6 + libgcc_s.so.1.

1. centos.7 – built with GCC 4.8.5 (patched); runs on glibc 2.17+
   Ideal for CentOS 7 / RHEL 7, Debian 8+, Ubuntu 14.04+.

2. linux – built with GCC 8.5.0; no source patches.
   Runs on glibc 2.28+ (RHEL 8+, Debian 10+, Ubuntu 20.04+, openEuler 20.03-lts, Deepin, …).
   👉 Recommended default for most users.

3. ubuntu.22.04 – built with GCC 11.2.0.
   Works on Ubuntu 22.04+, Debian 11+, RHEL 9+. Slightly narrower compatibility; may be retired if adoption is low.

Before 4.11.0, the “linux” package was built on Ubuntu 22.04, so 4.11.0 greatly improves compatibility.

Packages linux-musl-x64 / arm64 are built on Alpine 3.22 and statically link libstdc++ & libgcc.
Confirmed to run on Alpine 3.12 (musl 1.1.24) — even routers running OpenWrt!

android-x64 / arm64 compiled with Android NDK r27, API 24.
libstdc++ is statically linked, so drop-in ready for any device running Android 7.0+.

• osx-x64 for Intel Macs.
• osx-arm64 for Apple Silicon (M1 → M4).
Both cross-tested on macOS 14 & 15.

The following SKUs are now redundant; switch to the recommended replacements:

2. Consider a small donation – let me know your special needs and I’ll try to publish a build that fits.

Thanks for using OpenCvSharp mini-runtime and happy hacking!
