# Building Nix from Source
|
|
|
|
Nix is built with [Meson](https://mesonbuild.com/).
|
|
It is broken up into multiple Meson packages, which are optionally combined in a single project using Meson's [subprojects](https://mesonbuild.com/Subprojects.html) feature.
|
|
|
|
There are no mandatory extra steps to the building process:
|
|
generic Meson installation instructions like [this](https://mesonbuild.com/Quick-guide.html#using-meson-as-a-distro-packager) should work.
|
|
|
|
The installation path can be specified by passing the `-Dprefix=prefix`
|
|
to `configure`. The default installation directory is `/usr/local`. You
|
|
can change this to any location you like. You must have write permission
|
|
to the *prefix* path.
|
|
|
|
Nix keeps its *store* (the place where packages are stored) in
|
|
`/nix/store` by default. This can be changed using
|
|
`-Dstore-dir=path`.
|
|
|
|
> **Warning**
|
|
>
|
|
> It is best *not* to change the Nix store from its default, since doing
|
|
> so makes it impossible to use pre-built binaries from the standard
|
|
> Nixpkgs channels — that is, all packages will need to be built from
|
|
> source.
|
|
|
|
Nix keeps state (such as its database and log files) in `/nix/var` by
|
|
default. This can be changed using `-Dlocalstatedir=path`.
