Building melonJS

In order to build melonJS, you need to have GNU make and Java installed :

On windows, you should Install Cygwin (be sure to choose “make’ in the package list, note that it should be also possible to use GNU make for Windows), Java can be downloaded from here.

On OS X, you should install Xcode (both Xcode 3 & Xcode 4 version can be used).

On Linux/BSD users should use their appropriate package managers to install make and java.

  • Regular flavored build :

$ cd melonJS

$ mkdir build

$ make

Both plain and minified library will be available under the "build" directory

  • CoffeeScript flavored build :

First make sure that you have installed :

$ sudo npm install -g coffee-script

$ cd melonJS

$ npm install -d # Installs the deps from the package.json file

$ cake build:browser

Building the documentation

cd melonJS

make doc

The generated documentation will be then available under the "docs" directory
