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

|
