# 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 20.04
|
|
```bash
|
|
sudo apt-get install pkg-config libx11-dev libasound2-dev libudev-dev
|
|
```
|
|
|
|
## Fedora 32
|
|
```bash
|
|
sudo dnf install gcc-c++ libX11-devel alsa-lib-devel systemd-devel
|
|
```
|
|
|
|
## Arch / Manjaro
|
|
```bash
|
|
sudo pacman -S libx11 pkgconf alsa-lib
|
|
```
|
|
|
|
## Solus
|
|
```bash
|
|
sudo eopkg install pkg-config libx11-devel g++ alsa-lib-devel
|
|
```
|
|
|
|
## NixOS
|
|
|
|
Add a `build.rs` file to your project with the following:
|
|
|
|
```rust
|
|
fn main() {
|
|
if cfg!(target_os = "linux") {
|
|
println!("cargo:rustc-link-lib=vulkan");
|
|
}
|
|
}
|
|
```
|
|
|
|
The following packages are known to provide the dependencies required to run a bevy project. They can be installed globally or via nix-shell.
|
|
|
|
`nix-shell -p pkgconfig x11 xorg.libXcursor xorg.libXrandr xorg.libXi vulkan-tools lutris vulkan-headers vulkan-loader vulkan-validation-layers alsaLib`
|
|
|
|
Alternatively, you can copy the following code block and create a file called `shell.nix`. You can now enter nix-shell just by running `nix-shell`.
|
|
|
|
```nix
|
|
# shell.nix
|
|
|
|
{ pkgs ? import <nixpkgs> { } }:
|
|
|
|
pkgs.mkShell {
|
|
buildInputs = [
|
|
pkgs.alsaLib
|
|
pkgs.lutris
|
|
pkgs.pkgconfig
|
|
pkgs.vulkan-headers
|
|
pkgs.vulkan-loader
|
|
pkgs.vulkan-tools
|
|
pkgs.vulkan-validation-layers
|
|
pkgs.x11
|
|
pkgs.xorg.libXcursor
|
|
pkgs.xorg.libXi
|
|
pkgs.xorg.libXrandr
|
|
];
|
|
}
|
|
|
|
```
|
|
|
|
At this point, projects should successfully compile but fail on execution. This is due to `glslang_validator` which, unfortunately, needs to have it's binary patched to link correctly. This is a known issue and there are plans to remove this dependency.
|
|
|
|
1. `find target -type f -name glslang_validator` in order to find glslang_validator in `target/debug/build/bevy-glsl-to-spirv-<hash>/out/glslang_validator`. The directory containing glslang_validator will be referenced again, so save it for later: `export OUT_DIR="$(dirname $(find target -type f -name glslang_validator))"`.
|
|
2. Running `ldd $OUT_DIR/glslang_validator` may show `libstdc++.so.6` is not found. If all dependencies are found, then bevy should work. If not, install (globally or in nix-shell) any of the results found by `nix-locate -w libstdc++.so.6`. For example purposes, consider `nixos.gcc-unwrapped`. In theory, any of the ones in `find -L /nix/store -type f -name libstdc++.so.6` will work.
|
|
3. `patchelf --set-interpreter "$(cat $NIX_CC/nix-support/dynamic-linker)" --set-rpath /nix/store/784rh7jrfhagbkydjfrv68h9x3g4gqmk-gcc-8.3.0-lib/lib $OUT_DIR/glslang_validator`
|
|
4. Bevy should now be working properly!
