[MacRuby-devel] Stream of Consciousness Testing Log

[Pierce T. Wetter III]

  Ok, so I have a rubycocoa application with source freely available.  
So lets try to bootstrap it into MacRuby and see what happens.

  So first, lets copy the Xcode project file, since it seems like at  
this point there's no way to embed MacRuby directly so I'll have to  
tweak some settings in the project, and I don't want to have to undo  
them later when I go back to Rubycocoa. Or at least that's what I had  
to do last time.

  Let's make a new project in Xcode to get the settings I need since  
they don't seem to be documented in the Wiki.

  Hmmm... Making a new Ruby-Core Data application made what looks like  
a RubyCocoa app.

  Ah, there's a new thing called User Templates now. Must be a tweak  
because I'm using the iPhone SDK release of XCode.

  Ok, there's a Mac Ruby template project, loading that.

  Bringing up project settings to look for the settings...

  Hmmm... Don't see any. There were references to /usr/local last time  
I tried this.

  Well, lets run it and see what happens...

  No joy, can't find MacRuby/MacRuby.h

  Ok, the project template is broken. Maybe there's a developer  
example I can steal from instead.

  Trying DotView.

  Same problem. Ok, searching for the most recent xcoderproject  
version. Hmm. ABPresence looks newer.

  Nope, doesn't build either.

  Hmmm.. There's a MacRuby.framework listed in the project files,  
there didn't used to be.

  Trying to find it via locate.... no joy. Ok, ls /Library/Framework.

  I see it there. ls /Library/Framework/MacRuby/Framework

  Hmmm... I even see MacRuby.h:

more /Library/Frameworks/MacRuby.framework/Headers/MacRuby.h
#define RUBY_INCLUDED_AS_FRAMEWORK 1
#include "ruby/ruby.h"

  Hmm... Pretty short.

  Ok, so unlike the last time I tried, MacRuby is now just a framework  
to link against.

  Removing RubyCocoa.framework.
  Adding MacRuby.framework

  Opening the old main.m, saving it as main-mr.m, (which updates the  
project to point at the new file), editing it to call macruby_main.

  Hmmm... Same problem, never heard of MacRuby/MacRuby.h

  Well, I'll just comment out the import for now. Works in ABPresence,  
now lets try my app.

  ok, its building everything...I get a warning about macruby_main  
being implicitly defined, yadda, yadda.

  Running...

  Hmmm....

Assertion failed: (__auto_zone != NULL), function ruby_xmalloc, file  
gc.c, line 296.

The Debugger has exited due to signal 6 (SIGABRT).The Debugger has  
exited due to signal 6 (SIGABRT).

  I'm guessing, but I bet that I have to turn GC on, because it has to  
be OFF for RubyCocoa, but ON for MacRuby. Someone should put a useful  
message on that assertion like "Hey dummy, turn on GC".

  Ok, changing that to "supported"

  Doesn't like Sparkle, because I built it without GC.

  Ok, turning that on and rebuilding Sparkle. Now where did I put that?

  Ah, there it is. Changing garb to supported.

  Hmm... Its grumping about osx/cocoa getting included in rb_main.rb.  
Ok, doing my save-as trick again.

Ah, that doesn't work because I have to change main-mr.m as well.

Hmm... More problems because I'm using OSX:: Hey, I'm being a dummy, I  
can just copy rb_main.rb from Address book.

Ok, doing that, changing InstantMessage to CoreData.

Sigh, another complaint on a different OSX.require_Framework. Let's  
try this hack:

class OSX

	def OSX.require_framework(foo)
		framework foo
	end
end

before the requires.




Ok, running... That seems to work. But now I get:

Well, that's as far as I can get. Let me know if anyone wants all the  
necessary pieces zipped up somewhere. the rb_main.rb:13 above looks  
like a red herring though, because the code in that looks like this:

framework 'Cocoa'
framework 'AddressBook'  <--- line 13
