Hi there, after installing RubyCocoa on Mac OS X i tried the first steps with it in irb: That’s what happened > > require ‘osx/cocoa’ > > /usr/lib/ruby/site\_ruby/1.8/powerpc-darwin8.0/rubycocoa.bundle: [BUG] > > Bus Error > > ruby 1.8.2 (2004-12-25) [powerpc-darwin8.0] Abort trap Does anybody had the same probs or is it just because my machine is too old 😉 I remember bus errors very well from C++ Whats happening here? Does anybody know the answer and can help me? Kind regards norman ---

You can follow the Mac OS X instructions here: > **[Dan Benjamin](https://danbenjamin.com)** > > Dan Benjamin's personal website. That URL is even referenced by [developer.apple.com](http://developer.apple.com). Anyway, under Cocoa SIGBUS is usually received when something tries to send messages to an object which has already been released. The following Objective C code: [myObject release]; [myObject someMessage]; is likely to produce a Bus Error signal (as long as nothing else retains myObject). So, if upgrading ruby doesn’t actually fix the problem, there could be a bug of this kind within rubycocoa. (Finally Apple will release Objective C 2.0 with garbage collector along with Leopard! :)) ---

I’ve already installed the latest version of ruby in /usr/local/bin but “my ruby” with Rubycocoa doesn’t work. So i tried the internal ruby. Or should i just overwrite the internal ruby? Is that possible at least ? 🙂 ---

Or > should i just overwrite the internal ruby? Is that possible at least ? > 🙂 Did you install the binaries from the .dmg? I don’t know whether it looks for ruby in /usr/bin or /usr/local/bin. Anyway, it could be a RubyCocoa bug. Are you sure you’re using the latest version? Try downloading the latest stable version from SVN: svn co [RubyCocoa download | SourceForge.net](https://svn.sourceforge.net/svnroot/rubycocoa/trunk) rubycocoa Then you can compile and install it by typing: ruby install.rb config ruby install.rb setup sudo ruby install.rb install within the rubycocoa/src/ directory. Config should use --prefix=/usr/ local by default. If you don’t have svn, look here: [http://metissian.com/projects/](http://metissian.com/projects/) macosx/subversion/ (I had the fink version installed, but I think it was broken, I wasn’t able to install https support no matter how I tried. Maybe they fixed it now, I don’t really know). ---

Yes, that’s how you should install modules that you want to use with your /usr/local ruby installation. I’m not familiar with RubyCocoa, unfortunately. For most modules, you should just need to go through the usual installation procedure, but use /usr/local/bin/ruby instead of Apple’s ruby. Tom ---

Or > should i just overwrite the internal ruby? Is that possible at least ? Of course it’s possible, but it’s likely to be a bad idea. Among other reasons or other MacOSX software may expect Apple’s original installation to be there and some future Apple OS upgrade may want to modify or add to the builtin ruby. As a general rule, you should leave the Apple-installed unix utilities alone. Just install your own in /usr/local and make sure your PATH is set so that commands you issue use the /usr/local versions preferentially. There’s no reason I’m aware of that your own ruby installation (in / usr/local, or elsewhere) shouldn’t work. Tom
