Subject: “arch -i386 ruby” not loading into 32-bit mode in 10.6.3

<2.33GHz MBPC2D running OS X 10.6.3>

OSAX calls within the default 64-bit environment of OS X 10.6.3 (I have
not tried with earlier OS X versions) are failing when using what has
been recommended for forcing Ruby to run in 32-bit mode: “#! arch -i386
ruby”.

A test script, results, and software versions are appended below.

Thoughts?

Thanks!!

Richard Fairbanks


---- Script ----

#! arch -i386 ruby
require 'rubygems'
require 'appscript'; include Appscript
require 'osax'; include OSAX
p scripting_additions
#=> ["Digital Hub Scripting", "Numerics", "Satimage",
"SpeedDownloadLoader", "StandardAdditions", "XMLLib"]

# so good so far and non-OSAX scripts run as expected, but
# none of the following work:
osax.beep
osax.set_the_clipboard_to("howdy")
osax.say ("Hey, wake up.", :using=>"Victoria")

---- Results ----
