Weekly Builds

Below are the latest weekly builds from the stable (master) branch.

All files are approximately 6 MB in size (aside the Plan 9 builds which are 3 MB).

macOS (Darwin) builds for arm64 should support the ARM-based M1 processor. However please treat these builds as experimental. If you do run into any issues then log them at and use the amd64 builds in the meantime.

Linux / UNIX / macOS Instructions

Please download the appropriate .gz file from the list above, one that matches both your OS and CPU architecture.

For example, to download a 64bit version for Linux:

gunzip murex-linux-amd64.gz
chmod +x murex-linux-amd64

macOS builds are listed as darwin as per the name of Apple have given to their underlying OS.

Most of these builds have received some level of user acceptance testing with Linux and macOS builds receiving the most attention, because that's what we use ourselves.

Windows Instructions

Click the Windows link that matches your CPU architecture. Unzip using your preferred too then launch using your preferred console. murex cannot be started via double clicking the executable -- it requires a starting from within an existing console session.

Please also note that Windows support is also considered experimental. In part due to the lack of coreutils (as seen on Linux and UNIX) and in part due to the different underpinning technologies behind consoles / terminal emulators. If you do experience some wonky behavior then our recommendation is to run the linux-amd64 build for Linux on top of WSL. The instructions above will guide you through installing on Linux, WSL install instructions can be found at the following site:

Plan9 Instructions

Plan9 is untested. The code compiles and it is syscall compatible with Plan9 operating systems, however you may experience bugs using murex on Plan9. If you do encounter any issues then please raise them at:

This site's content is rebuilt automatically from murex's source code after each merge to the master branch. Downloadable murex binaries are also built with the website.
