# Hacking
|
||
|
|
|
||
|
|
This section provides some notes on how to hack on Nix. To get the
|
||
|
|
latest version of Nix from GitHub:
|
||
|
|
|
||
|
|
$ git clone https://github.com/NixOS/nix.git
|
||
|
|
$ cd nix
|
||
|
|
|
||
|
|
To build Nix for the current operating system/architecture use
|
||
|
|
|
||
|
|
$ nix-build
|
||
|
|
|
||
|
|
or if you have a flakes-enabled nix:
|
||
|
|
|
||
|
|
$ nix build
|
||
|
|
|
||
|
|
This will build `defaultPackage` attribute defined in the `flake.nix`
|
||
|
|
file. To build for other platforms add one of the following suffixes to
|
||
|
|
it: aarch64-linux, i686-linux, x86\_64-darwin, x86\_64-linux. i.e.
|
||
|
|
|
||
|
|
$ nix-build -A defaultPackage.x86_64-linux
|
||
|
|
|
||
|
|
To build all dependencies and start a shell in which all environment
|
||
|
|
variables are set up so that those dependencies can be found:
|
||
|
|
|
||
|
|
$ nix-shell
|
||
|
|
|
||
|
|
To build Nix itself in this shell:
|
||
|
|
|
||
|
|
[nix-shell]$ ./bootstrap.sh
|
||
|
|
[nix-shell]$ ./configure $configureFlags
|
||
|
|
[nix-shell]$ make -j $NIX_BUILD_CORES
|
||
|
|
|
||
|
|
To install it in `$(pwd)/inst` and test it:
|
||
|
|
|
||
|
|
[nix-shell]$ make install
|
||
|
|
[nix-shell]$ make installcheck
|
||
|
|
[nix-shell]$ ./inst/bin/nix --version
|
||
|
|
nix (Nix) 2.4
|
||
|
|
|
||
|
|
If you have a flakes-enabled nix you can replace:
|
||
|
|
|
||
|
|
$ nix-shell
|
||
|
|
|
||
|
|
by:
|
||
|
|
|
||
|
|
$ nix develop
|
