ps/2 mouse error

I need the ps2dev library

I'm sorry that was working on the wrong library.

Anyhow...

In ps2dev.h, comment out the line that includes WConstants.h. Put in a lline that includes WProgram.h:

/*
 * ps2dev.h - a library to interface with ps2 hosts. See comments in
 * ps2.cpp.
 * Written by Chris J. Kiick, January 2008.
 * modified by Gene E. Scogin, August 2008.
 * Release into public domain.
 */

#ifndef ps2dev_h
#define ps2dev_h

//#include "WConstants.h"  // The original line---for really old arduino stuff
#include "WProgram.h"      // This is what you should have for arduino-0021

class PS2dev
{
.
.
.

With that change I find that arduino-0021 compiles it without problems.

Regards,
