#53 MacOS X: librxtxSerial problem

[Serge Droz]

Starting on MacOS X does not work:
Error below. Solution found on: http://tech.element77.com/2009/06/arduino-problems-with.html
Maybe this could/should included in current MacOS Distros.

Error:

Hi Serge

The RXTX2.2 version is included with the distribution and available through the webstart. That contains a library compatible with your system.

Apparently you are running from the zip in which case the startup script (bt747_macosX_j2se.command) seems to need some refinements.
I wonder what $major_minor turns up to be. Can you launch the script in a terminal after changing the first line to

#!/bin/bash -vx

That will make sure that every executed line gets echoed and the variable expansions are resolved and shown to (on lines starting with '+' in the output).

Ok,

I was running ./run_j2se.sh
and not bt747_macosX_j2se.command
The later does work fine.
Sorry for the false alert
