Hi Gareth, Have a look at the examples in Developer/Examples/Ruby/MacRuby - there are good examples there which might be useful for you. In this case your init method is an obvious problem, it must (as in objective C) return self. The super call is interesting because normally in ruby it will call your current method in the super class and magically pass on parameters you had to the current object's method to the super class. I cannot find an example of super.method in Pickaxe, but nonetheless super.initWithSomething(params) - has worked fine for me. Someone will correct me, I am sure, i this is wrong. so you could try: def init if (super initWithWindowNibName('preferences')) #initialisation stuff return self end nil end or more or less the same: def init result = super.initWithWindowNibName('Preferences') if result #other initialisation end result end cheers, John On Fri, Nov 27, 2009 at 12:51 AM, Gareth Townsend <gareth.townsend@me.com>wrote:
Hi,
I've just started playing with MacRuby. So please bear with me, there's every chance I'm doing something stupid :-) I'm using 0.5 beta 2.
I'm building a simple Cocoa App (http://github.com/quamen/noise) and am running into some problems while trying to set up a Preference Pane.
Specifically this error:
Assertion failed: (m != NULL), function rb_vm_super_lookup, file dispatcher.cpp, line 228.
Followed by a whole heap of warnings that seem to hard coded to Laurent's machine
Program received signal: “SIGABRT”.
sharedlibrary apply-load-rules all warning: Could not find object file "/Users/lrz/src/macruby-clean/array.o" - no debug information available for "array.c".
warning: Could not find object file "/Users/lrz/src/macruby-clean/bignum.o" - no debug information available for "bignum.c".
...
This occurs when I try to instantiate an NSWindowController subclass. My Code:
def open_preferences(sender) NSLog('open preferences') preference_controller ||= PreferencesController.new preference_controller.showWindow(self) end
class PreferencesController < NSWindowController def init if (super initWithWindowNibName('preferences')) self else nil end end
end
I have a .xib file called 'preferences.xib'
So can anyone spot something stupid? If not, how should I go about debugging this?
