Hi, Objective-C could use GC and non-GC for memory management on the
desktop.

So in that case Ruby would be garbage collected, but ObjC code it
uses will be ref counted?

Hi Conrad,
The thing is, MacRuby is built on top of the ObjC GC, so there is
currently no way you can not use it :)
In the future we might introduce a mode where MacRuby doesn't use
this GC, but it's all tentative.

Laurent, I understand that one should use the GC for MacRuby but why
do we have such a restriction? Just curious about the history here.
Thanks in advance,

Hi Robert,
The problem here is dealloc. Same reason, dealloc is ignored by the
runtime, and you should not use it in MacRuby, it will never be
called.
I just fixed macruby to not crash in case autorelease or dealloc is
used, but keep in mind that using these selectors won't do anything.

Hi Laurent:
Thanks for your quick reply. I have attached another file that
causes a similar crash without a call to autorelease.

Hi Robert,
The problem is line 68, the call to autorelease. If you remove it it
should load again. The reason is that autorelease (like release and
retain) are ignored selectors of the runtime. Clearly we should not
crash this way, I will fix that.
Also, keep in mind that retain, release and autorelease should not
be used in MacRuby. We run under GC mode which makes these calls no-
ops.

Hi Laurent:
Thanks for your offer to help. Sorry I was busy with another project
but now I get back to MacRuby.
I have attached a file that causes the assertion error when loaded
by the require command. Probably there is something else I need to
change when porting from Ruby-Cocoa.
Thanks,

Hi Robert,
Unless you found what was wrong, feel free to contact me off-list
with a copy of your app and I will investigate the problem.

Hi Laurent:
It's a relatively large application that I ported from a RubyCocoa
environment.
I need the threading support hook that was removed from Ruby in the
Snow Leopard release.
I'll try to track it down better by porting and testing modules a
little at a time.
Thanks,

Looks like we are hitting an assertion in the symbol generator...
Could you send us what you are trying to execute here?

Latest trunk code available as an unofficial pkg ready to install:

Lots of bug fixes, improved macgem (not finished yet but you can
install gems and load them using `gem 'gem_name'; require
'whatever'`).
Things are looking pretty good on trunk :)
