Multiple Duplicate interface and redefinition errors

Excelcius

Hi all Im having problems with Multiple Duplicate interface and redefinition errors in my Sparrow project, All was working fine until recently I hadn't complied the project in a while and changed some code and now I recompiled the project and got these errors . Initially there was just a couple of errors things like "definition of objects prohibited in structs" but when I tried to delete the offending struct the error would still be there hovering over empty space, upon recompiling the deleted code reappeared, not sure whats going on there but I assumed Xcode was breaking something again.

So I deleted the derived data and I got the multiple Duplicate errors, the error seems to be pointed to classes I haven't touched so not sure whats going on, the classes implicated in each instance seem to follow this pattern

In QPMaths Class in Sparrow 2.1

@interface QPMaths : NSObject

Duplicate interface definition for class 'QPMaths'

in my project prefix.pch in MyGame

#import <Sparrow/Sparrow.h>

In file included from /Users/gareth/Work/Games/MyGame/iphone/MyGame/src/App-Prefix.pch:9:

in Sparrow.h in Sparrow 2.1

#import "QPTitle.h"

in QPTitle.h in Sparrow 2.1

Previous definition is here

Ive changed a couple of my classes in Sparrow since the last successful compile but not QPTitle and QPSprite and these 2 classes seem to come up time and time again, But most of the changes have been in MyGame. However I have another project which links to the same version of the sparrow framework and that compiles fine so Im at a loss any help greatly appreciated

OK I seem to have solved it, the problem was QPTitle.h was missing from the build phases of Sparrow 2.1. I keep running into this same problem. header files seemingly for no reason get deleted from the build phases list. Does anybody know why this might keep occurring ? Else they weren't included to begin with, but in that case why didn't these errors occur before ? Driving a little bit nuts now, Any suggestions ? Thanks in advance.
