I haven't solved the problem with 64 bit Arduino crashing under 64 bit SUSE v11.1, but I've got a practical workaround. I simply use VirtualBox to run 32 bit SUSE v11.1 under 64 bit SUSE, and hence the 32 bit Arduino packages.

Both Arduino v0011 and v0012 then work fine according to the setup instructions on the Arduino website.

But note that to get USB virtualisation working, some configuration (hacking?) is needed. This is a problem both for SUSE, see :
<http://forums.opensuse.org/applications/391984-virtualbox.html>
and for Ubuntu, see :

Hi Ver! Thanks for responding.

Up until now, I was using the IDE via a desktop link, so saw no messages. I've just tried running the IDE directly from within a terminal window and got the following :

I've just installed 64bit arduino-0012 on my SUSE Linux v11.1 machine, as per the clear directions given on the Arduino website. Installation went fine and the Arduino IDE runs OK. I can edit, compile, and upload programs to my Arduino Diecimila board, just as I have done previously under 32 bit SUSE/arduino-0011.

However, when I now send a command to the Arduino board via the IDE/USB connection, the IDE shuts down. This didn't happen under the 32 bit installation.

The command is definitely sent correctly before the shutdown/crash occurs.

Any suggestions?

I've developed a dual stepper motor driver program for Arduino. Presently this project includes:

1. Program to run on Arduino to allow for fully independent control of two bi-polar stepper motors.
2. Motor driver board to run with Arduino and provide up to 600mA per motor winding.
3. GUI interface to run on a PC. Includes versions to run under 32 bit and 64 bit Linux and also under 32 bit Microsoft Windows XP

Find full details and programs/source code at:

Please feel free to use this. Feedback/comments please.
