Getting started

This is a quick guide for getting started with Darjeeling. It should explain everything from checking out the code to compiling your first Darjeeling build.

Before you start

Before you can start developing with Darjeeling, there are some prerequisites.

Operating system

This short tutorial assumes that you're using Linux, in fact it's the weapon of choice for most of the developers working on Darjeeling. We also provide some information about getting things to work on OSX. Things haven't been tested with Windows or Windows/Cygwin, so you're pretty much on your own if you want to use that. Feel free to ask questions on the forum though.

Java 1.6

Darjeeling requires Java 1.6. Ubuntu/Debian/Mint users installing the Sun JDK 1.6 is pretty straightforward, just install the sun-java6-jdk package. Make sure you use the sun JDK, since we haven't tested with anything else.

For OSX users Java 1.6 should come pre-installed, but is not standard on older Pentium Macs. One workable option is to install SoyLatte. This installs into /usr/local so it can coexist with the standard MacOS java, you just need to set your path appropriately when you are building Darjeeling.

SoyLatte has a known issue where the @Override annotation will generate errors when used with a method that implements an interface method. If you get weird errors conceSelect the application that should be builtrning @Override on mac/soylatte, this might be your problem. We don't know of any workarounds, so it's probably best to just remove/comment out the offending @Override tags from your Java code.


The build system uses Apache ANT. The Ubuntu package is simply called ant. We're pretty sure it will work with 1.7.1.


You'll need to install GCC to build the Linux version of Darjeeling, and the appropriate ports for AVR and MSP430. Ubuntu users will find both gcc-msp430 and avr-gcc in the standard repositories.

Obtaining the source

Check out the source from SVN:

svn co https://darjeeling.svn.sourceforge.net/svnroot/darjeeling/trunk darjeeling

Common requirements

set environment variables

Add DARJEELING to your path, so you can simply copy and past the commands from this guide. export DARJEELING=<path to darjeeling>

Build the infuser

cd $DARJEELING/src/infuser ant


You can run darjeeling natively on your computer. Just follow these steps.

Go to the directory for builds for the native system

cd $DARJEELING/src/config/native

Select the application that should be built

Edit build.xml and change the property "apps". Currently it is set to "testsuite", you can change it to "blink". The applications are located in $DARJEELING/src/apps. Note: you can also specify multiple applications, seperated by a comma. They will be run in parallel.

Run the application

./darjeeling.elf That's all. Your java application is now running on top of darjeeling.
