from the projects' websites. Below are some example ways to get setup.
### windows-msvc Specific Setup
1. `rustup default stable-x86_64-pc-windows-msvc`
2. Install [Build Tools for Visual Studio 2017](https://visualstudio.microsoft.com/downloads/#build-tools-for-visual-studio-2017). If you have already been using this toolchain then its probably already installed.
3. Install [msys2](http://www.msys2.org/), following ALL of the instructions.
4. Then in the msys2 terminal run: `pacman --noconfirm -Syu mingw-w64-x86_64-cmake mingw-w64-x86_64-python3`
5. Add the msys2 mingw64 binary path to the PATH environment variable.
### Windows-gnu Specific Setup
windows-gnu toolchain is not supported but you can instead cross-compile to windows-gnu from windows-msvc
Steps 1 and 2 are to workaround https://github.com/rust-lang/rust/issues/49078 by using the same mingw that rust uses.
1. Download and extract https://s3-us-west-1.amazonaws.com/rust-lang-ci2/rust-ci-mirror/x86_64-6.3.0-release-posix-seh-rt_v5-rev2.7z
2. Add the absolute path to mingw64\bin to your PATH environment variable. (This path needs to be before the msys2 path)
3. Run the command: `rustup default stable-x86_64-pc-windows-msvc`
4. Run the command: `rustup target install x86_64-pc-windows-gnu`
5. Install [Build Tools for Visual Studio 2017](https://visualstudio.microsoft.com/downloads/#build-tools-for-visual-studio-2017). If you have already been using this toolchain then its probably already installed.
6. Install [msys2](http://www.msys2.org/), following ALL of the instructions.
7. Then in the msys2 terminal run: `pacman --noconfirm -Syu mingw64/mingw-w64-x86_64-pkg-config mingw-w64-x86_64-gcc mingw-w64-x86_64-cmake mingw-w64-x86_64-make mingw-w64-x86_64-python3`
8. Add the msys2 mingw64 binary path to the PATH environment variable.
9. Any cargo command that builds the project needs to include `--target x86_64-pc-windows-gnu` e.g. to run: `cargo run --target x86_64-pc-windows-gnu`
### Linux Specific Setup
Use your package manager to install the required dev-tools and vulkan drivers
For example on ubuntu:
```
sudo apt-get install build-essential git python cmake libvulkan-dev vulkan-utils
```
### macOS and iOS Specific Setup
