# Building the shaders

You will need `glslangValidator` and `spirv-cross` installed to execute the
Makefile from this directory. You can speed up the build by parallelizing the
build: `make -j`.

## macOS

You can use [Homebrew](https://brew.sh/) to install the dependencies:

```sh
brew install glslang spirv-cross
```

## Windows

`glslangValidator` and `spirv-cross` are available by installing the
[Vulkan SDK](https://vulkan.lunarg.com/sdk/home). You'll also need some commands
like `make`, `rm`, etc. These are available on the
[Windows Subsystem for Linux](https://docs.microsoft.com/en-us/windows/wsl/install-win10)
shell. You'll need to set these environment variables for `make` to succeed:

```sh
export GLSLANG=glslangValidator.exe
export SPIRVCROSS=spirv-cross.exe
```

Note: the Windows versions of `glslangValidator` and `spirv-cross` may change
the line endings of the generated output. Please take care to ensure that
unintended line ending changes aren't accidentally commited, for instance by
[configuring Git to automatically handle line endings](https://docs.github.com/en/github/using-git/configuring-git-to-handle-line-endings#global-settings-for-line-endings).
