/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”.

sharedlibrary apply-load-rules all

No memory available to program now: unsafe to call malloc

Unable to restore previously selected frame:

Cannot access memory at address 0x9a41

Also, could you confirm that it also fails for other frameworks?

macruby -e "framework 'Foundation'"

If this works, then I suspect MacRuby finds a Cocoa.framework somewhere in your disk that is not the right one.

In case you pass a string (ex. foo) to #framework, it will search for foo.framework in the following locations (in this order):

~/Library/Frameworks
/Library/Frameworks
/System/Library/Frameworks

Can you double-check in the 2 first directories that there is nothing wrong there?

Hi Alistair,

So, looking at the error you pasted earlier, it seems that it's raised in the following objc.m logic:

if (![bundle loadAndReturnError:&error]) {
rb_raise(rb_eRuntimeError,
"framework at path `%s' cannot be loaded: %s",
cstr,
[[error description] UTF8String]);
}

In other words, -[NSBundle loadAndReturnError:] doesn't seem to work. This looks like a problem in Foundation.

Could you try the following snippets?

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

In my environment both print "1".

Does anyone have any ideas on this? It's driving me mad not being able to use MacRuby on my MBP. I really don't want to have to try doing something like a clean system install.

BTW - I installed MacRuby the same way on my MP and have had no problems with it at all.

I've just upgraded to Snow Leopard and installed again from trunk but I'm still having the same issue with not being able to load the Cocoa framework in macirb. :(

Perhaps I'll give installing another go. I did install 0.4 and went onto install from trunk afterwards but neither worked at the time. I'll let you know what happens.

I had the same problem occuring a few days ago, after reinstalling macruby trunk today, everything is back to normal.

Hi Laurent,

Thanks for the reply. I ran it and got:

~ $ macruby -e "framework '/System/Library/Frameworks/Cocoa.framework'; p :ok"
:ok

My filesystem is definitely not case sensitive.

Hi Alistair,

This is very strange... could you try the following command?

$ macruby -e "framework '/System/Library/Frameworks/Cocoa.framework'; p :ok"

Also, maybe your filesystem is case sensitive? The default format is case insensitive, in theory.

Hello,

I've just installed MacRuby (MacRuby version 0.4 (ruby 1.9.1) [universal-darwin9.5, x86_64]) via the package I downloaded from http://www.macruby.org and I dropped straight into macirb to start on the tutorial (http://www.macruby.org/documentation/tutorial.html). I ran framwork 'Cocoa' and uh oh.. a RuntimeError popped up.

I've seen another thread on this list from January with the same issue but there wasn't really any fix detailed. I've posted my console output of lots of different commands at https://gist.github.com/359195517cc2364b82b8.

I'm running 10.5.8 on a MacBook Pro 2.4Ghz Intel Core 2 Duo. Hard disk format is Mac OS Extended (Journaled).

Hopefully someone can help me out.

Thanks
