Building from Source

1. Install Racket

2. Install Waxeye's backend for Racket.

   • Unix and OSX

     sudo ln -s /usr/local/waxeye/src/racket/waxeye /usr/local/racket/lib/racket/collects/

   • Windows

     Copy the directory src/racket/waxeye into your Racket collects directory. For example, C:\Program Files\Racket\collects.

3. Build Waxeye

   • Unix and OSX

     ./build/unix

   • Windows

     • If your Racket installation isn't C:\Program Files\Racket, then you will need to modify build\exe.bat to use the correct path.

     • From your Waxeye installation directory, run the build\exe.bat script in a command prompt.
