[MacRuby-devel] RuntimeError: framework at path `Cocoa' cannot be loaded in macirb?

Sun Aug 30 03:18:51 PDT 2009

Thanks for all the help Laurent. Here are the results:
Both of the following print "1":

$ macruby -e "p
NSBundle.bundleWithPath('/System/Library/Frameworks/Cocoa.framework').loadAndReturnError(nil)"
$ macruby -e "p
NSBundle.bundleWithPath('/System/Library/Frameworks/Cocoa.framework').load"

Trying to load Foundation with $ macruby -e "framework 'Foundation'" worked.

And as for the directories

 ~/Library/Frameworks - Doesn't exist
 /Library/Frameworks - Doesn't contain Cocoa.framework
 /System/Library/Frameworks - Cocoa.framework is in here

The only other places I could find Cocoa.framework is in:

/Developer/SDKs/MacOSX10.5.sdk/System/Library/Frameworks/
/Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/

Urgh! I was just about to send this email and though I'd try framework
'Cocoa' again to see the error it produced and guess what, it worked! So I
closed the macirb process and fired it up again to check once more and it
failed with the same error as earlier. :'(

I'm having major trouble building and running MacRuby apps from Xcode as
well, although I expect that is down to the same issue? Sometimes it builds
and sometimes it fails with things like:

Program received signal:  “EXC_BAD_INSTRUCTION”.

and

Program received signal:  “EXC_BAD_ACCESS”.
