muon is an implementation of the meson build system in c99 with minimal dependencies.


  • bug-for-bug compatibility with meson. In fact, muon aspires to be stricter than meson in cases where meson's implementation seems error prone. muon uses the official meson documentation as its specification.
  • cli compatibility with meson. muon has different flags, subcommands, etc., and should not be renamed/symlinked to meson.

Contributions welcome:

  • language support for languages other than C and C++

Other differences from meson are described in doc/differences.md


muon is complete enough to build complicated projects, however, many things are still not implemented. If you want to contribute, try using muon to build your favorite project. Patches and bug reports welcome!


muon requires various POSIX interfaces and a compiler offering c99 support.

In addition, dependency discovery requires libpkgconf, and wrap support requires libcurl and libarchive.

A ninja-compatible build tool (e.g. samurai) is also required to bootstrap muon, but can be optionally embedded into muon after bootstrapping.

Documentation requires scdoc in order to be built.


You can bootstrap muon like this:

./bootstrap.sh build

You can then use the bootstrapped muon to build itself:

build/muon setup build
ninja -C build

Although I had already had the idea to re-implement meson in C, I was initially inspired to actually go out and do it when I saw boson. muon's code was originally based on boson, though has since been almost completely rewritten.
