Installing the tool chain

MacOS

To compile and flash the software to your NXT 2.0 Brick leJos is needed. Watch the following video until 12:24 and follow the steps.

Video

The steps are:

1. Download and install Java 6 from https://support.apple.com/kb/DL1572?locale=de_DE.

Notice that your java virtual machine isn't installed in the location mentioned in the video. It is installed at

/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

To determine the location run (see https://stackoverflow.com/a/26507569)

/usr/libexec/java_home -V

2. Download and install leJOS from https://sourceforge.net/projects/lejos/files/lejos-NXJ/. Choose the latest version.

• Unpack the tar.gz

• Move the folder to some suitable directory (home for instance).

  mv ~/Downloads/leJOS_NXJ_* ~/leJOS_NXJ

• Set the environment variables. You can use the commands from this page. But make sure to use the paths from 1. and 2.

  export NXJ_HOME="~/leJOS_NXJ"
  export LEJOS_NXT_JAVA_HOME="/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home"
  export PATH="$NXJ_HOME/bin:$PATH"

3. Install the drivers for the brick. Download the drivers from https://www.lego.com/de-de/mindstorms/downloads and install them.

Now you should be able to build and flash when running the build.sh.

Linux and Windows
