On Linux and macOS the easiest way to Install Nix is to run the following shell command
|
||||
(as a user other than root):
|
||||
|
||||
```
|
||||
```console
|

$ curl -L https://nixos.org/nix/install | sh

## Building And Developing
|
||||
|
||||
### Building Nix
|
||||
|
||||
You can build Nix using one of the targets provided by [release.nix](./release.nix):
|
||||
|
||||
```
|
||||
$ nix-build ./release.nix -A build.aarch64-linux
|
||||
$ nix-build ./release.nix -A build.x86_64-darwin
|
||||
$ nix-build ./release.nix -A build.i686-linux
|
||||
$ nix-build ./release.nix -A build.x86_64-linux
|
||||
```
|
||||
|
||||
### Development Environment
|
||||
|
||||
You can use the provided `shell.nix` to get a working development environment:
|
||||
|
||||
```
|
||||
$ nix-shell
|
||||
$ ./bootstrap.sh
|
||||
$ ./configure
|
||||
$ make
|
||||
```
|
||||
See our [Hacking guide](https://hydra.nixos.org/job/nix/master/build.x86_64-linux/latest/download-by-type/doc/manual#chap-hacking) in our manual for instruction on how to
|
||||
build nix from source with nix-build or how to get a development environment.

make install</programlisting>
|
||||
</example>
|
||||
|
||||
<para><xref linkend='ex-hello-builder' /> shows the builder referenced
|
||||
from Hello's Nix expression (stored in
|
||||
<filename>pkgs/applications/misc/hello/ex-1/builder.sh</filename>).
|
||||
The builder can actually be made a lot shorter by using the
|
||||
<emphasis>generic builder</emphasis> functions provided by
|
||||
<varname>stdenv</varname>, but here we write out the build steps to
|
||||
elucidate what a builder does. It performs the following
|
||||
steps:</para>
|
||||
|
||||
<calloutlist>
|
||||
|
||||
<callout arearefs='ex-hello-builder-co-1'>
|
||||
|
||||
<para>When Nix runs a builder, it initially completely clears the
|
||||
environment (except for the attributes declared in the
|
||||
derivation). For instance, the <envar>PATH</envar> variable is
|
||||
empty<footnote><para>Actually, it's initialised to
|
||||
<filename>/path-not-set</filename> to prevent Bash from setting it
|
||||
to a default value.</para></footnote>. This is done to prevent
|
||||
undeclared inputs from being used in the build process. If for
|
||||
example the <envar>PATH</envar> contained
|
||||
<filename>/usr/bin</filename>, then you might accidentally use
|
||||
<filename>/usr/bin/gcc</filename>.</para>
|
||||
|
||||
<para>So the first step is to set up the environment. This is
|
||||
done by calling the <filename>setup</filename> script of the
|
||||
standard environment. The environment variable
|
||||
<envar>stdenv</envar> points to the location of the standard
|
||||
environment being used. (It wasn't specified explicitly as an
|
||||
attribute in <xref linkend='ex-hello-nix' />, but
|
||||
<varname>mkDerivation</varname> adds it automatically.)</para>
|
||||
|
||||
</callout>
|
||||
|
||||
<callout arearefs='ex-hello-builder-co-2'>
|
||||
|
||||
<para>Since Hello needs Perl, we have to make sure that Perl is in
|
||||
the <envar>PATH</envar>. The <envar>perl</envar> environment
|
||||
variable points to the location of the Perl package (since it
|
||||
was passed in as an attribute to the derivation), so
|
||||
<filename><replaceable>$perl</replaceable>/bin</filename> is the
|
||||
directory containing the Perl interpreter.</para>
|
||||
|
||||
</callout>
|
||||
|
||||
<callout arearefs='ex-hello-builder-co-3'>
|
||||
|
||||
<para>Now we have to unpack the sources. The
|
||||
<varname>src</varname> attribute was bound to the result of
|
||||
fetching the Hello source tarball from the network, so the
|
||||
<envar>src</envar> environment variable points to the location in
|
||||
the Nix store to which the tarball was downloaded. After
|
||||
unpacking, we <command>cd</command> to the resulting source
|
||||
directory.</para>
|
||||
|
||||
<para>The whole build is performed in a temporary directory
|
||||
created in <varname>/tmp</varname>, by the way. This directory is
|
||||
removed after the builder finishes, so there is no need to clean
|
||||
up the sources afterwards. Also, the temporary directory is
|
||||
always newly created, so you don't have to worry about files from
|
||||
previous builds interfering with the current build.</para>
|
||||
|
||||
</callout>
|
||||
|
||||
<callout arearefs='ex-hello-builder-co-4'>
|
||||
|
||||
<para>GNU Hello is a typical Autoconf-based package, so we first
|
||||
have to run its <filename>configure</filename> script. In Nix
|
||||
every package is stored in a separate location in the Nix store,
|
||||
for instance
|
||||
<filename>/nix/store/9a54ba97fb71b65fda531012d0443ce2-hello-2.1.1</filename>.
|
||||
Nix computes this path by cryptographically hashing all attributes
|
||||
of the derivation. The path is passed to the builder through the
|
||||
<envar>out</envar> environment variable. So here we give
|
||||
<filename>configure</filename> the parameter
|
||||
<literal>--prefix=$out</literal> to cause Hello to be installed in
|
||||
the expected location.</para>
|
||||
|
||||
</callout>
|
||||
|
||||
<callout arearefs='ex-hello-builder-co-5'>
|
||||
|
||||
<para>Finally we build Hello (<literal>make</literal>) and install
|
||||
it into the location specified by <envar>out</envar>
|
||||
(<literal>make install</literal>).</para>
|
||||
|
||||
</callout>
|
||||
|
||||
</calloutlist>
|
||||
|
||||
<para>If you are wondering about the absence of error checking on the
|
||||
result of various commands called in the builder: this is because the
|
||||
shell script is evaluated with Bash's <option>-e</option> option,
|
||||
which causes the script to be aborted if any command fails without an
|
||||
error check.</para>
