29	29	Another issue is that the development package of **libusb** has to be installed. On Ubuntu you can do this by using **{{code language="none"}}sudo apt-get install libusb-dev{{/code}}**.

31		-Furthermore, to use USB connection, a java library has to be compiled via ant. To do this perform **cd /path/to/leJOS/build** and start ant. If the ant build tool is not installed on your system, you can do so via **sudo apt-get install ant**.

35	35	The setup.exe of the current LEGO Fantom driver for Windows (1.2.0) has an awkward issue. If you get an error message (Developer Error) because an .msi file could not be found, don't panic. The file is part of the downladed archive (in the Products folder) but you have to start it manually.

	37	+==== Mac OS X ====

	39	+The **leJOS NXJ** tools require a **32 Bit** version of Java. However, newer 32 Bit versions of Java are not longer available for Mac. Thus to use leJOS the installation of **Java 1.6 is required**, which is the last one that supports a 32 Bit mode. You can download the installer for Java 1.6 from [[https:~~/~~/support.apple.com/kb/dl1572?locale=en_US>>url:https://support.apple.com/kb/dl1572?locale=en_US||shape="rect"]]. It will install Java 1.6 to ///System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home// so that the environment variable //LEJOS_NXT_JAVA_HOME//, which is set in the installation instructions, points to the correct path.
	40	+
	41	+The environment variable LEJOS_NXT_JAVA_HOME is set in the installation tutorial by editing ~~/.profile. However, on a Mac the environment variables defined in this file are not visible for GUI Applications, only for apps started from terminal. Thus to use leJOS together with KIELER one either has to start KIELER from terminal or set the environment variable so that all GUI applications can access it, which seems to be not trivial on Mac (see also [[http:~~/~~/stackoverflow.com/questions/135688/setting-environment-variables-in-os-x>>url:http://stackoverflow.com/questions/135688/setting-environment-variables-in-os-x||shape="rect"]]).
