leJOS: Windows Installation

Windows Intallation of leJOS

The only difference between the Unix distributions and the win32 distributions of leJOS is that the latter ones contain Windows executables. These executables depend on the CygWin B20.1 DLL, which is distributed in the bin directory, and are meant to be run from a DOS console. To run leJOS from a CygWin console, you should download the Unix distribution, or run make.

To install leJOS:

Unzip the file you downloaded. A top directory, lejos, is already provided.
Set RCXTTY to the IR serial port, e.g. set RCXTTY=COM2.
Both the JDK's and leJOS' bin directories should be in your PATH.

Under Windows 95/98, you might want to create a batch file that sets these variables, and specify that batch file in the Program properties of a DOS console shortcut; or set them in C:\AUTOEXEC.BAT.
