Memcached for Windows — ServBay Portable Build

memcached is a high-performance, multithreaded, event-based key/value cache store intended to be used in a distributed system.

This repository produces a native Windows build of memcached — no Cygwin, no WSL, no compatibility layer. It is cross-compiled with MinGW-w64 into a native Windows memcached.exe, based on the MinGW port from jefyt/memcached-windows merged on top of upstream memcached.

It is maintained by ServBay and packaged for consumption by ServBay-PKG-Builder-v1.

Each release publishes:

File	Description
memcached-<version>-win64-mingw.zip (or win32)	The portable build
memcached-<version>-win64-mingw.zip.sha256	SHA-256 checksum

• Release tag: memcached-<version>-win-<arch> (e.g. memcached-1.6.44-win-x64).
• Verify the download against its .sha256 file before use.

How it's built

Releases are produced by the Build Memcached for Windows workflow (workflow_dispatch, run manually):

• Inputs: memcached_version (e.g. 1.6.44), arch (x64 / x86), skip_tests.
• Toolchain: runs on ubuntu-latest (24.04) — not in Docker — using ubuntu's gcc-mingw-w64, so the toolchain is pinned and reproducible.
• Self-test: the cross-compiled memcached.exe is launched under wine and load-tested with mc-crusher (memcached's own make test cannot run a cross-compiled .exe natively).
• Publish: the archive plus its SHA-256 are attached to a GitHub Release.

Environment

Minimum requirement: Windows Vista / Windows Server 2008.

• NOTE: -s/--unix-socket requires at least Windows 10 version 1803 / Windows Server 2016 version 1803. Run sc query afunix to check whether the OS supports it; a socket-creation error will occur on unsupported systems.

Running

• Just execute memcached.exe (options are the same except the unsupported ones below).
• Run memcached.exe --help for more info.

Unsupported

These upstream options do not apply on Windows:

• sasl — use -Y/--auth-file with TLS/SSL enabled as an alternative.
• -u/--user — use Windows runas, Explorer's Run as different user, or other built-in Windows tools instead.
• -r/--coredumps — MinGW-w64 does not support coredumps; use native Windows crash dumps instead.
• -k/--lock-memory — Windows does not support locking all paged memory.
• seccomp — Linux-only.
