Just installed the new MacRuby 0.9 and I still have this problem.
I'm assuming it's something I've screwed up, and hints and tips greatly
welcomed...

Hi, I'm trying to apply a predicate to a core data fetch and hitting
EXC_BAD_ACCESS.
I've successfully used NSPredicate to filter an array's contents, but all my
attempts to use NSPredicate with Coredata fail.
I'm using framework 'Coredata' and framework 'Foundation' and this is the

Hi, another MacRuby 0.9 question...
I've been trying to use lambda and/or Proc.new to provide callback blocks (as
suggested in Matt's excellent draft book). Again I have seen discussions about
problems in this area and for me all the suggested variants of code fail.
Here's a snip of failing cod
Hi, I have been trying to use the NSDate initWithTimeInterval:sinceDate: method
to measure elapsed times.
I know there has been some discussion about the mapping from Cocoa NSDate to
Ruby Time and back but I'm not sure if this is supposed to be working now?

Hi, I'm back to using MacRuby again and I'm confused about Bridge Support.
I have been using the excellent sojaster port of the Cocoa OpenGL example to
help develop an OpenGL playpen. However, when I started using glut calls
(glutBitmapCharacter, glutStrokeString, etc) I started to get problems.
OK, thanks for all the comments. I'll move any new SL questions to the
Dev Forums.
However, for what it's worth. I have now been able to build & install
the experimental branch on SL. There was only one snag... I had to
remove .gem/macruby/1.9.1/bin from my path in order to get rake to run.
Rich,
Thanks, I'll try 0.5 again and see how I do.
regards, Jonathan

Should we expect MacRuby 0.4 to work under the SnowLeopard beta? I'm
seeing crashes in both macirb and magem (see below). I've also tried
0.5 branch and that has crashes as well.
(hope you're all enjoying WWDC)
Crashes MacIrb:

Matt, Thank you. It hadn't occured to me that the 'C' dependency would
upset the MacGem process! I'll think about the issues of Ruby OpenGL
v. Cocoa OpenGl.
John, Thank you for sharing the examples... More reading to do :)

Hi, I'm just starting to use MacRuby and I would like to be able to
use OpenGL. So far I have been unable to install the GEM.
I have just checked out the current MacRuby trunk (Mon 25 May) and
after building it I get the following error:
sudo macgem install ruby-opengl
