In issuing some Computer Science students with a Raspberry Pi I decided I would like them to be able to program in Python on them (job done already as it comes pre-installed) and I would also like them to be able to use Greenfoot.
I came across a great post on the Raspberry Pi website that I have re-written below with shortcuts to everything needed.
Firstly you need to install Java on the Raspberry Pi.
Create a directory to install it to:
mkdir -p /opt
Download the Linux Java package from here:
Then decompress the Java package:
sudo tar zxvf (name of package) -C /opt
Make sure it’s installed ok, this should return the version:
sudo /opt/jdk1.8.0/bin/java -version
Now that Java is installed, you can go ahead and install Greenfoot once you have downloaded the Pure Java Version from here.
Greenfoot can be installed using the following command:
sudo /opt/jdk.8.0/bin/java -jar /home/pi/GreenfootVersion.jar
A window should pop up with details of where Java is installed and where you want to install Greenfoot, click install then done.
Providing you kept to the defaults you can now run Greenfoot from the greenfoot script in the /home/pi/greenfoot directory or by using the ./greenfoot command from within the Greenfoot directory.
