## Nix with flakes
|
||||
|
||||
This section assumes you are using Nix with [flakes] enabled. See the [next section](#classic-nix) for equivalent instructions which don't require flakes.

||||

||||
[flakes]: ../command-ref/new-cli/nix3-flake.md#description
|
||||
|
||||
To build all dependencies and start a shell in which all environment
|
||||
variables are set up so that those dependencies can be found:
|
||||
|
||||
```console
|
||||
$ nix-build
|
||||
$ nix develop
|
||||
```
|
||||
|
||||
or if you have a flake-enabled nix:
|
||||
This shell also adds `./outputs/bin/nix` to your `$PATH` so you can run `nix` immediately after building it.
|
||||
|
||||
To get a shell with one of the other [supported compilation environments](#compilation-environments):
|
||||
|
||||
```console
|
||||
$ nix develop .#native-clang11StdenvPackages
|
||||
```
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> Use `ccacheStdenv` to drastically improve rebuild time.
|
||||
> By default, [ccache](https://ccache.dev) keeps artifacts in `~/.cache/ccache/`.
|
||||
|
||||
To build Nix itself in this shell:
|
||||
|
||||
```console
|
||||
[nix-shell]$ ./bootstrap.sh
|
||||
[nix-shell]$ ./configure $configureFlags --prefix=$(pwd)/outputs/out
|
||||
[nix-shell]$ make -j $NIX_BUILD_CORES
|
||||
```
|
||||
|
||||
To install it in `$(pwd)/outputs` and test it:
|
||||
|
||||
```console
|
||||
[nix-shell]$ make install
|
||||
[nix-shell]$ make installcheck -j $NIX_BUILD_CORES
|
||||
[nix-shell]$ nix --version
|
||||
nix (Nix) 2.12
|
||||
```
|
||||
|
||||
To build a release version of Nix:
|
||||
|
||||
```console
|
||||
$ 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.
|
||||
You can also build Nix for one of the [supported target platforms](#target-platforms).

$ nix-build -A defaultPackage.x86_64-linux

by:
|
||||
You can also build Nix for one of the [supported target platforms](#target-platforms).
|
||||
|
||||
## Platforms
|
||||
|
||||
As specified in [`flake.nix`], Nix can be built for various platforms:
|
||||
|
||||
- `aarch64-linux`
|
||||
- `i686-linux`
|
||||
- `x86_64-darwin`
|
||||
- `x86_64-linux`
|
||||
|
||||
[`flake.nix`]: https://github.com/nixos/nix/blob/master/flake.nix
|
||||
|
||||
In order to build Nix for a different platform than the one you're currently
|
||||
on, you need to have some way for your system Nix to build code for that
|
||||
platform. Common solutions include [remote builders] and [binfmt emulation]
|
||||
(only supported on NixOS).
|
||||
|
||||
[remote builders]: ../advanced-topics/distributed-builds.md
|
||||
[binfmt emulation]: https://nixos.org/manual/nixos/stable/options.html#opt-boot.binfmt.emulatedSystems
|
||||
|
||||
These solutions let Nix perform builds as if you're on the native platform, so
|
||||
executing the build is as simple as
|
||||
|
||||
```console
|
||||
$ nix develop
|
||||
$ nix build .#packages.aarch64-linux.default
|
||||
```
|
||||
|
||||
for flake-enabled Nix, or
|
||||
|
||||
```console
|
||||
$ nix-build -A packages.aarch64-linux.default
|
||||
```
|
||||
|
||||
for classic Nix.
|
||||
|
||||
You can use any of the other supported platforms in place of `aarch64-linux`.
|
||||
|
||||
Cross-compiled builds are available for ARMv6 and ARMv7, and Nix on unsupported platforms can be bootstrapped by adding more `crossSystems` in `flake.nix`.
|
||||
|
||||
## Compilation environments
|
||||
|
||||
Nix can be compiled using multiple environments:
|
||||
|
||||
- `stdenv`: default;
|
||||
- `gccStdenv`: force the use of `gcc` compiler;
|
||||
- `clangStdenv`: force the use of `clang` compiler;
|
||||
- `ccacheStdenv`: enable [ccache], a compiler cache to speed up compilation.
|
||||
|
||||
To build with one of those environments, you can use
|
||||
|
||||
```console
|
||||
$ nix build .#nix-ccacheStdenv
|
||||
```
|
||||
|
||||
for flake-enabled Nix, or
|
||||
|
||||
```console
|
||||
$ nix-build -A nix-ccacheStdenv
|
||||
```
|
||||
|
||||
for classic Nix.
|
||||
|
||||
You can use any of the other supported environments in place of `nix-ccacheStdenv`.
|
||||
|
||||
## Editor integration
|
||||
|
||||
The `clangd` LSP server is installed by default on the `clang`-based `devShell`s.
|
||||
See [supported compilation environments](#compilation-environments) and instructions how to set up a shell [with flakes](#nix-with-flakes) or in [classic Nix](#classic-nix).
|
||||
|
||||
To use the LSP with your editor, you first need to [set up `clangd`](https://clangd.llvm.org/installation#project-setup) by running:
|
||||
|
||||
```console
|
||||
make clean && bear -- make -j$NIX_BUILD_CORES install
|
||||
```
|
||||
|
||||
Configure your editor to use the `clangd` from the shell, either by running it inside the development shell, or by using [nix-direnv](https://github.com/nix-community/nix-direnv) and [the appropriate editor plugin](https://github.com/direnv/direnv/wiki#editor-integration).
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> For some editors (e.g. Visual Studio Code), you may need to install a [special extension](https://open-vsx.org/extension/llvm-vs-code-extensions/vscode-clangd) for the editor to interact with `clangd`.
|
||||
> Some other editors (e.g. Emacs, Vim) need a plugin to support LSP servers in general (e.g. [lsp-mode](https://github.com/emacs-lsp/lsp-mode) for Emacs and [vim-lsp](https://github.com/prabirshrestha/vim-lsp) for vim).
|
||||
> Editor-specific setup is typically opinionated, so we will not cover it here in more detail.
