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

sudo apt-get install g++ pkg-config libx11-dev libasound2-dev libudev-dev

if using Wayland, you will also need to install

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 on how to set up graphics and audio.

Fedora

sudo dnf install gcc-c++ libX11-devel alsa-lib-devel systemd-devel

if using Wayland, you will also need to install

sudo dnf install wayland-devel libxkbcommon-devel

If there are errors with linking during the build process such as:

 = 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:

sudo dnf install alsa-lib-devel.x86_64

Or if there are errors such as:

  --- 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

error: build failed

Set the PKG_CONFIG_PATH env var to /usr/lib/<target>/pkgconfig/. For example on an x86_64 system:

export PKG_CONFIG_PATH="/usr/lib/x86_64-linux-gnu/pkgconfig/"

Arch / Manjaro

sudo pacman -S libx11 pkgconf alsa-lib

Install pipewire-alsa or pulseaudio-alsa depending on the sound server you are using.

Void

sudo xbps-install -S pkgconf alsa-lib-devel libX11-devel eudev-libudev-devel

NixOS

Add a shell.nix file to the root of the project containing:

{ pkgs ? import <nixpkgs> {} }:
with pkgs; mkShell rec {
  nativeBuildInputs = [
    pkgconfig
    llvmPackages.bintools # To use lld linker
  ];
  buildInputs = [
    udev alsaLib vulkan-loader
    xlibsWrapper xorg.libXcursor xorg.libXrandr xorg.libXi # To use x11 feature
    libxkbcommon wayland # To use wayland feature
  ];
  LD_LIBRARY_PATH = pkgs.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".

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 to nativeBuildInputs.

OpenSUSE

   sudo zypper install libudev-devel gcc-c++ alsa-lib-devel

Gentoo

   sudo emerge --ask libX11 pkgconf alsa-lib

Clear Linux OS

sudo swupd bundle-add devpkg-alsa-lib
sudo swupd bundle-add devpkg-libgudev
