Thanks for your quick reply. The hot patch seems to work.
You may find serialport named as 'ruby-serialport'.
At one time I had serialport working in ruby 1.8.7 but then after attempting to install some other Gems I now get the error:
irb 0.9.5(05/04/13)
new-host:~ robertrice$ ruby -v
ruby 1.8.7 (2008-08-11 patchlevel 72) [i686-darwin9.7.0]
new-host:~ robertrice$ irb

irb(main):002:0> require "serialport"
[BUG] cross-thread violation on rb_gc()
ruby 1.8.6 (2008-08-11) [universal-darwin9.0]
Abort trap
new-host:~ robertrice$ exit
logout
[Process completed]
Could you suggest a fix for this?
Thanks,

For XML, you can use Cocoa API or if you want to ue REXML, you need to use the hot patch I mentioned there:

Regarding the serialport library, I can't seem to see it on rubyforge, so I'm not sure what you are referring to.

Dear MacRuby development team:
I am new to Ruby and I have an application that I would like to port to MacRuby. The two extensions I will need are XML and serial port I/O.
So far I have not been able to get them to work:

Can anyone help me? Do I have a bad installation of MacRuby?
Thanks,
