# Linux

	sudo apt-get install make gcc bison git python python-setuptools

	git clone git://github.com/bentley/rgbds.git
	cd rgbds
	sudo make install
	cd ..

	git clone --recursive git://github.com/kanzure/pokecrystal.git
	cd pokecrystal

- Copy a Pokémon Crystal rom into `pokecrystal/`. Name it **baserom.gbc**. Eventually this will not be required.

To build **pokecrystal.gbc**:

	make


# OS X

On 10.8 or earlier, download and install **Command Line Tools for Xcode**.

On 10.9 or later:

	xcode-select --install

In the shell, run:

	git clone git://github.com/bentley/rgbds.git
	cd rgbds
	sudo make install
	cd ..

	git clone --recursive git://github.com/kanzure/pokecrystal.git
	cd pokecrystal

- Copy a Pokémon Crystal rom into `pokecrystal/`. Name it **baserom.gbc**. Eventually this will not be required.

To build **pokecrystal.gbc**:

	make


# Windows

To build on Windows, use [**Cygwin**](http://cygwin.com/install.html) (32-bit).

In the installer, select the following packages: `make` `git` `python` `python-setuptools` `gcc` `libsasl2` `ca-certificates`

Then get the most recent version of [**rgbds**](https://github.com/bentley/rgbds/releases/).
Put `rgbasm.exe`, `rgblink.exe` and `rgbfix.exe` in `C:\cygwin\usr\local\bin`.

In the **Cygwin terminal**:

	git clone --recursive git://github.com/kanzure/pokecrystal.git
	cd pokecrystal

- Copy a Pokémon Crystal rom into `C:\cygwin\home\<username>\pokecrystal`. Name it **baserom.gbc**. Eventually this will not be required.

To build:

	make


# Vagrant

The simplest way to get pokecrystal to compile is to use Vagrant and
VirtualBox. Follow these steps:

* [Download and install Vagrant](http://www.vagrantup.com/downloads.html)
* Follow the instructions to [download and install VirtualBox](http://docs-v1.vagrantup.com/v1/docs/getting-started/)
* Run these commands:

```
	vagrant box add pokecrystal http://diyhpl.us/~bryan/irc/pokecrystal/pokecrystal.box
	mkdir vagrantbox
	cd vagrantbox
	vagrant init pokecrystal
	vagrant up
	vagrant ssh -c "cd /vagrant && git clone --recursive git://github.com/kanzure/pokecrystal.git"
	vagrant ssh
```

Running "vagrant ssh" will give you a shell to type commands into for compiling
the source code. Then the "virtualbox" directory on the host appears as a shared
folder inside of the guest virtual machine at "/vagrant".

To build the project, run these commands in the guest (that is, inside "vagrant
ssh"):

	cd /vagrant/pokecrystal
	make

To make the build work you will need to copy baserom.gbc into the "pokecrystal"
directory inside the "virtualbox" directory on the host machine. Eventually
this will not be required.
