Installing a supported Rust compiler

Azul (version 0.1.0) is supported on Rust 1.31 or newer. Please ensure that you have the right compiler version, by running rustc -vV after installation to check the version number.

Installation on Windows


If you get prompted to install the MSVC toolchain, please download both the Visual C++ tools (available from here) and install the Windows 8 or 10 SDK (which contains the actual linker) from the Visual Studio Tools installer.


If you choose the MinGW toolchain on windows, 32-bit support is missing, due to problems with a C dependency. Because of this, we recommend you to use the MSVC toolchain on Windows or use a 64-bit compiler.

DownloadFile -FileName rustup-init.exe rustup-init -yv --default-toolchain stable --default-host x86_64-pc-windows-msvc

...or download the windows installer manually from

Installation on Linux / Mac

curl -sSf | sh

If you do not trust executing a remote script, download the script seperately, review it and then execute it. You can also find the installation instructions for Rust on the main website.

Notes for NixOS

In order to install the dependencies for NixOS, copy this into a `shell.nix` in your directory of choice and run `nix-shell` to install the dependencies.

with import >nixpkgs< {}; stdenv.mkDerivation { name = "rust-env"; nativeBuildInputs = [ rustup pkgconfig python3 ]; buildInputs = [ freetype xorg.libxcb # for dialogs gnome3.zenity ]; LD_LIBRARY_PATH = stdenv.lib.makeLibraryPath [ xorg.libX11 xorg.libXcursor xorg.libXrandr xorg.libXi libglvnd ]; }
## System dependencies You currently need to install [CMake]( before you can use azul. This applies to all platforms, since CMake is used during the build process to compile `servo-freetype` and `harfbuzz-sys`. ### Linux On Linux, you additionally need to install `libexpat-dev` and `libfreetype6-dev` in order to compile `servo-freetype-sys`(see [#42]( For interfacing with the system clipboard, you also need `libxcb-xkb-dev`. Since azul uses the system-native fonts by default, you'll also need `libfontconfig1-dev` (which includes expat and freetype2). Your users will need to install `libfontconfig` and `libxcb-xkb1` installed (remember this for packaging rpm or deb packages). Lastly, if there is no OpenGL available, azul will fallback and try to find ``. Especially when testing inside of a VM, it is important to install `libgles2-mesa-dev` - note that the software will compile if this library isn't present, it just won't run without it. ``` sudo apt install \ cmake libxcb-xkb-dev libfontconfig1-dev libgles2-mesa-dev \ libfreetype6-dev libexpat-dev ``` **Note for Arch Linux:** On Arch, the package for `libfontconfig1-dev` seems to be called `fontconfig`. Other dependencies are statically linked in all binaries, you don't need to worry about managing them. ## Creating a new project Once you have Rust and Cargo installed, create a new project in the directory of your choice: ```bash cargo new --bin my_first_azul_app cd my_first_azul_app cargo run ``` ## Adding azul to your dependencies Open the /my_first_azul_app/Cargo.toml file and paste the following lines beneath the [dependencies] section: ```toml [dependencies] azul = { git = "" } ``` **WARNING: ** Azul has not yet been released on, therefore, there is no package available. This guide will be updated once the first stable version releases. It is recommended to version-lock your dependency with `{ git = "...", rev = "the_last_commit_hash" }`, so that you know which commit you are using. This will pull in the latest stable version of azul. Open the `/my_first_azul_app/src/` file and edit it to look like this: ```rust extern crate azul; fn main() { println!("Hello world!"); } ``` Ensure that azul builds correctly by running cargo run again. Azul does not require third-party dependencies (dynamic libraries), it should build out-of-the-box. If that's the case, you are ready to move on to the next page, starting to actually build your first GUI app with azul. If not, please report this as a bug.
