Build Rack plugins for Mac, Windows, and Linux with a single command on any Linux distro.
Coming soon: Use Docker to build on Mac, Windows, or Linux.


## Building

Clone this repository in a path without spaces, or the Makefile will break.

Obtain `MacOSX10.13.sdk.tar.bz2` using the method at https://github.com/tpoechtrager/osxcross#packaging-the-sdk, and place it in the root of this repository.
This must be done on a computer with Mac 10.13.

Build toolchains for each platform.
```
make toolchain-linux
make toolchain-windows
make toolchain-mac
```
Each toolchain will take around an hour to build, requiring network access and about 15 GB free disk space.
The final disk space after building is about 1.6 GB.

Download the latest Rack SDK.
```
make rack-sdk
```

## Building plugins

Build plugin package for all platforms.
```
make plugin-build PLUGIN_DIR=...
```

This places packages in `plugin-build/`.
