Extending Titanium Mobile with Module SDK possible?

I read this document:
http://developer.appcelerator.com/doc/mobile/iphone/module_sdk

I cannot get it to work with 1.3.2 and Xcode 3.2.3. After creating my project from xcode using Appcelerator/Titanium Mobile Module template, I get the example code, but it complains about the "Base SDK Missing". So I edit the project settings and update the Base SDK from 3.1.3 to 3.2, then I edit the manifest, type '% python build.py' :

I unzip this to /Library/Application Support/Titanium, update my modules in tiapp.xml, as instructed, but it the simulator never starts up. Weird.

http://gist.github.com/491515

So it is loading 'myphonenumber/0.1' but doesn't go any further.

Is there a log somewhere I can read to get more info when things break? Ah ha, found build.log:

Undefined symbols:
"_ADBannerContentSizeIdentifier320x50", referenced from:
_ADBannerContentSizeIdentifier320x50$non_lazy_ptr in TiUIiOSAdViewProxy.o
(maybe you meant: _ADBannerContentSizeIdentifier320x50$non_lazy_ptr)
"_OBJCCLASS$_ADBannerView", referenced from:
objc-class-ref-to-ADBannerView in TiUIiOSAdView.o
"_ADBannerContentSizeIdentifier480x32", referenced from:

(maybe you meant: _ADBannerContentSizeIdentifier480x32$non_lazy_ptr)
ld: symbol(s) not found
collect2: ld returned 1 exit status

Not sure how to fix this?

I am running into the exact same bug, using the 1.4.0 Titanium SDK release, and iOS SDK 4, when trying a base case of building the Clipboard SDK extension module in with my newly created app. As a sanity check, both are 100% unmodified from the defaults (e.g. my app is a stock new project created in Titanium Developer, and with the clipboard module I just changed it to build up against 1.4.0 instead of 1.3.0).

The clipboard SDK extension module I am talking about is at: http://github.com/xavierlacot/titanium_mobile_clipboard_module

(I'll be gutting it and replacing it with EventKit logic once I can get past this bug)

Any help for us would be greatly appreciated! Will have to write a native app if I can't figure this out, as I need eventkit functionality….:/

- I have been trying to create a module to use the Event Kit over the last few days and found exactly the same issue. Is there anything else to try?
  
  I am using SDK 1.4 building for ios4
  
  The error I get is:
  Undefined symbols:
  "OBJC_CLASS$_EKEventStore", referenced from:
  objc-class-ref-to-EKEventStore in libcalendar.a(CalendarModule.o)
  "OBJC_CLASS$_EKEvent", referenced from:
  objc-class-ref-to-EKEvent in libcalendar.a(CalendarModule.o)
  ld: symbol(s) not found
  collect2: ld returned 1 exit status
  
  This may be down to my module as I have never used Objective C before and have just been cutting and pasting what I have found in Appcelerator and Apple documentation. If it is of any use the code is as follows:
  
  CalendarModule.h :-
```
import "TiModule.h"
@interface CalendarModule : TiModule { }
@end
```
  CalendarModule.m :-
```
import "CalendarModule.h"
import "TiBase.h"
import "TiHost.h"
import "TiUtils.h"
import <EventKit/EventKit.h>
@implementation CalendarModule

id arg4 = [args objectAtIndex:3];  // Location
id arg5 = [args objectAtIndex:4];  // Text

NSDateFormatter *df = [[NSDateFormatter alloc] init];
[df setDateFormat:@"yyyy-MM-dd hh:mm:ss"];
NSDate *startdate = [df dateFromString: arg1];
NSDate *enddate = [df dateFromString: arg2];

EKEventStore *eventStore = [[[EKEventStore alloc] init] autorelease];

EKEvent *event  = [EKEvent eventWithEventStore:eventStore];

event.title     = arg3;
event.location  = arg4;
event.notes     = arg5;
event.startDate = startdate;
event.endDate   = enddate;

[event setCalendar:[eventStore defaultCalendarForNewEvents]];
NSError *err;
[eventStore saveEvent:event span:EKSpanThisEvent error:&err];

return event.eventIdentifier;

}

@end

- You need to delete the comments as referred to above, there is a new builder in a different directory, sorry can't remember the path but it is easy to search for.
  
  If you need to import a framework use the following code:
  
  Added the following line to module.xcconfig, OTHER_LDFLAGS=$(inherited) -framework EventKit.
  
  It now works perfectly

See this ticket
```
#
# PLACE ANY BUILD DEFINITIONS IN THIS FILE AND THEY WILL BE 
# PICKED UP DURING THE APP BUILD FOR YOUR MODULE
#
```
Delete this code from module.xcconfig. Comments should use double slash (//).

I created my own module under 1.3.0 templates and I could compile, link, and run with appcelerator.

But i can't get the same module to run against 1.4.0.

Do I need to install new template from 1.4.0? There is a new install.py (in a different directory path then 1.3.0). I'm not sure what that is doing yet.
