Hi Rich, I forgot to mention that the installer wouldn't work on non-Intel machines. We cannot support PPC anymore due to lack of resources, however as stayed in the Rakefile warning, it should still work. The build error you're getting is about the readline extension, it has nothing to do with PPC (if you look at the tracker you should see a report and how to fix the problem).

You can learn more about MacRuby, and download a binary installer, from the website:

http://ruby.macosforge.org

Or about this release more specifically, on our blog:

http://www.macruby.org/post/macruby-04

Neither the posting, the web site, nor the blog mentions the fact that the binary installer for the new release doesn't include support for PowerPC machines:

$ file /usr/local/bin/macruby /usr/local/bin/macruby: Mach-O universal binary with 2 architectures /usr/local/bin/macruby (for architecture i386): Mach-O executable i386 /usr/local/bin/macruby (for architecture x86_64): Mach-O 64-bit executable x86_64

I downloaded the sources

$ svn co http://svn.macosforge.org/repository/ruby/MacRuby/tags/0.4 \ MacRuby-0.4

and attempted to follow the build instructions on

http://www.macruby.org/trac/wiki/InstallingMacRuby

$ cd MacRuby MacRuby: No such file or directory.

Sigh.

$ ls MacRuby-0.4

$ cd MacRuby-0.4

$ rake (in /Local/_Private/Homes/rdm/Private/Work/MacRuby/MacRuby-0.4) Warning: your appear to use a PowerPC machine. MacRuby's PPC support is very basic and may be dropped in a near future.

I think this falls a bit below "very basic support". :-/

I have no argument with Laurent or Apple about their current priorities: making MacRuby build and run on PowerPC is a burden that Laurent does not need at this point in the development process. Nor do I have the chops or time to dig into the sources and try to make the build work.

However, it's possible that some other folks might be motivated to follow along behind Laurent and produce the occasional PowerPC build. Any takers?

Meanwhile, I updated http://www.macruby.org/trac/wiki/InstallingMacRuby to reflect the new reality. The blog does not allow comments, so I was unable to post a caveat there.
