# Installing Linux dependencies
This page lists the required dependencies to build a Bevy project on your Linux machine.
If you don't see your distro present in the list, feel free to add the instructions in this document.
## [Ubuntu](https://ubuntu.com/)
```bash
sudo apt-get install g++ pkg-config libx11-dev libasound2-dev libudev-dev
```
if using Wayland, you will also need to install
```bash
sudo apt-get install libwayland-dev libxkbcommon-dev
```
Depending on your graphics card, you may have to install one of the following:
`vulkan-radeon`, `vulkan-intel`, or `mesa-vulkan-drivers`
Compiling with clang is also possible - replace the `g++` package with `clang`.
### Windows Subsystem for Linux (WSL 2)
Graphics and audio need to be configured for them to work with WSL 2 backend.
Please see the ubuntu [WSL documentation](https://wiki.ubuntu.com/WSL) on how to set up graphics and audio.
## [Fedora](https://getfedora.org/)
```bash
sudo dnf install gcc-c++ libX11-devel alsa-lib-devel systemd-devel
```
if using Wayland, you will also need to install
```bash
sudo dnf install wayland-devel libxkbcommon-devel
```
If there are errors with linking during the build process such as:
```bash
= note: /usr/bin/ld: skipping incompatible /usr/lib/libasound.so when searching for -lasound
/usr/bin/ld: skipping incompatible /usr/lib/libasound.so when searching for -lasound
/usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-redhat-linux/10/../../../libasound.so when searching for -lasound
/usr/bin/ld: skipping incompatible /lib/libasound.so when searching for -lasound
/usr/bin/ld: skipping incompatible /usr/lib/libasound.so when searching for -lasound
/usr/bin/ld: cannot find -lasound
```
Add your arch to the end of the package to remove the linker error. For example:
```bash
sudo dnf install alsa-lib-devel.x86_64
```
Or if there are errors such as:
```txt
--- stderr
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: "`\"pkg-config\" \"--libs\" \"--cflags\" \"libudev\"` did not exit successfully: exit status: 1\n--- stderr\nPackage libudev was not found in the pkg-config search path.\nPerhaps you should add the directory containing `libudev.pc'\nto the PKG_CONFIG_PATH environment variable\nNo package 'libudev' found\n"', /home/<user>/.cargo/registry/src/github.com-1ecc6299db9ec823/libudev-sys-0.1.4/build.rs:38:41

```
Set the `PKG_CONFIG_PATH` env var to `/usr/lib/<target>/pkgconfig/`. For example on an x86_64 system:
```txt
export PKG_CONFIG_PATH="/usr/lib/x86_64-linux-gnu/pkgconfig/"
```
## Arch / Manjaro
```bash
sudo pacman -S libx11 pkgconf alsa-lib
```
Install `pipewire-alsa` or `pulseaudio-alsa` depending on the sound server you are using.
Depending on your graphics card, you may have to install one of the following:
`vulkan-radeon`, `vulkan-intel`, or `mesa-vulkan-drivers`
## Void
```bash
sudo xbps-install -S pkgconf alsa-lib-devel libX11-devel eudev-libudev-devel
```
## [Nix](https://nixos.org)
Add a `shell.nix` file to the root of the project containing:
```nix
{ pkgs ? import <nixpkgs> { } }:
with pkgs;
mkShell rec {
nativeBuildInputs = [
pkg-config
];
buildInputs = [
udev alsa-lib vulkan-loader
xorg.libX11 xorg.libXcursor xorg.libXi xorg.libXrandr # To use the x11 feature
libxkbcommon wayland # To use the wayland feature
];
LD_LIBRARY_PATH = lib.makeLibraryPath buildInputs;
}
```
And enter it by just running `nix-shell`.
You should be able compile Bevy programs using `cargo run` within this nix-shell.
You can do this in one line with `nix-shell --run "cargo run"`.
This is also possible with [Nix flakes](https://nixos.org/manual/nix/unstable/command-ref/new-cli/nix3-flake.html).
Instead of creating `shell.nix`, you just need to add the derivation (`mkShell`)
to your `devShells` in `flake.nix`. Run `nix develop` to enter the shell and
`nix develop -c cargo run` to run the program. See
[Nix's documentation](https://nixos.org/manual/nix/unstable/command-ref/new-cli/nix3-develop.html)
for more information about `devShells`.
Note that this template does not add Rust to the environment because there are many ways to do it.
For example, to use stable Rust from nixpkgs, you can add `cargo` and `rustc` to `nativeBuildInputs`.
[Here](https://github.com/NixOS/nixpkgs/blob/master/pkgs/games/jumpy/default.nix)
is an example of packaging a Bevy program in nix.
## [OpenSUSE](https://www.opensuse.org/)
```bash
sudo zypper install libudev-devel gcc-c++ alsa-lib-devel
```
## Gentoo
```bash
sudo emerge --ask libX11 pkgconf alsa-lib
```
When using an AMD Radeon GPU, you may also need to emerge `amdgpu-pro-vulkan` to get Bevy to find the GPU.
When using a NVIDIA GPU with the proprietary driver (eg. `x11-drivers/nvidia-drivers`), you may also need to emerge `media-libs/vulkan-loader` to get Bevy to find the GPU. NVIDIA Vulkan driver is included in `nvidia-driver`, but may need the loader to find the correct driver. See Gentoo [Documentation](https://wiki.gentoo.org/wiki/Vulkan) for details.
## [Clear Linux OS](https://clearlinux.org/)
```bash
sudo swupd bundle-add devpkg-alsa-lib
sudo swupd bundle-add devpkg-libgudev
```
## [Alpine Linux](https://alpinelinux.org/)
Run the following command to install `GNU C compiler, standard C development libraries, pkg-config, X11 development libraries, ALSA development libraries, eudev development libraries`:
```sh
sudo apk add gcc libc-dev pkgconf libx11-dev alsa-lib-dev eudev-dev
```
Install a GPU renderer for you graphics card. For Intel integrated GPUs:
```sh
sudo apk add mesa-vulkan-intel
```
If you have issues with `winit` such as `Failed to initialize backend!` or similar, try adding the following to your `~/.cargo/config.toml` (more information at the [issue #1818](https://github.com/rust-windowing/winit/issues/1818) of the [winit repository](https://github.com/rust-windowing/winit):
```toml
[build]
rustflags = ["-C", "target-feature=-crt-static"]
```
