entropy_db sample does not compile for device

What steps will reproduce the problem?
1. Load sample project
2. Click Build


Please provide any additional information below.

I get the following errors on build:

Disregard.  I didnt read the manual.  I see that it only works with the 
simulator
now.  Is there any timeframe as to when it will compile on the device?

The problem is that the underlying ObjC runtime has changed in Objective-C 2.0. 
We are rewriting our code 
base, a version for the device will be available for download in 1-2 weeks.

Shoot, I didn't realize this only worked in the Simulator.  I ran into this same
problem and searched all around for an answer to the problem.  Well, at least 
now I
know it's not something I did wrong.

Please keep us updated on the status of this rewrite.

Thanks!

Please try to use the attached file, it's a static library compiled for the ARM 
architecture.

I used this new version and it seems to build.  Unfortunately, I'm still 
encountering
an error about "Verifying application" which seems to be unrelated to entropy 
db. 
But thank you for fixing this for us!

Also, the new version doesn't compile for the Simulator.  Is that to be 
expected?  Do
I need to switch them out whenever I use the Simulator or the device?

This is normal behavior as it's not possible to create a static library for 
both ARM and Intel (Simulator).

I've tried the arm version of the library and get the following error when 
running my
app (note, it runs fine under the simulator).  It seems to occur in the 
[EXContainer
initWithFile:] method:

For some reason, the method -className is absent from the device. Please add 
the following NSObject category to your project:

#import <Foundation/Foundation.h>

@interface NSObject (iPhone)

- (NSString*)className;

@end

@implementation NSObject (iPhone)

- (NSString*)className {
    return NSStringFromClass([self class]);
}

@end

Perfect, the category did it.  The app now works on the phone :)

Thanks!

I got the same error.  Where do I add the above code?  Is it a new file?  And 
if so,
what should the name of the file be?

Thanks!

Okay, I figured it out.  Created NSObject.h and NSObject.m with the above code 
split
into each as appropriate.  My app now works on my phone, but when I try to 
store an
object, I get this error:

2008-08-08 17:36:38.609 CC Roulette[640:20b] *** -[EXContainer store:]: 
unrecognized
selector sent to instance 0x1482d0
2008-08-08 17:36:38.616 CC Roulette[640:20b] *** Terminating app due to uncaught

unrecognized selector sent to instance 0x1482d0'
2008-08-08 17:36:38.635 CC Roulette[640:20b] Stack: ( etc );

Is this something that I'm doing wrong or something that is going wrong with 
this code?

You should use storeObject:

Entropy appears to be a fairly dead project.  Use CoreData instead.  It is 
faster,
more flexible and a LOT more robust.
