Problem adding Classes to Sparrow Framework

Excelcius

Hi all Im trying to add some objective c classes directly to the Sparrow 2.1 framework, I have a folder called "myFramework" with other folders inside to further organise my classes. Ive copied this folder over to Sparrow/src/classes

I right click on my classes folder in the the Xcode project navigator and select Add files to "Sparrow" then select the "myFramework" folder, copy files if needed is unchecked, Added folders is create groups, Add to targets "Sparrow" and "Unit tests" are checked but when I run Sparrow I get the following errors there are more errors for each one of my classes but the list is too long to paste here.

duplicate symbol _OBJC_METACLASS_$_QPTouch in:
/Users/me/Library/Developer/Xcode/DerivedData/Sparrow-blbdanyrjqeanbbramnnndndzzsa/Build/Intermediates/Sparrow.build/Debug-iphonesimulator/UnitTests.build/Objects-normal/UnitTests-x86_64-master.o
/Users/me/Library/Developer/Xcode/DerivedData/Sparrow-blbdanyrjqeanbbramnnndndzzsa/Build/Products/Debug-iphonesimulator/libSparrow.a(libSparrow.a-x86_64-master.o)

linker command failed with exit code 1 (use -v to see invocation)(null):
423 duplicate symbols for architecture x86_64

I have tried adding "myFramework" without Add to targets "Sparrow" and "Unit tests" and it compiles OK but when I run my barebones project it throws an error that it can't find the first of "myFramework" headers which Ive added to the Sparrow.h file

Having looked through my projects settings the classes appear in BuildPhases>headers>project and BuildPhase>CompiledScources and I can't see any duplicates so Im at a loss as to what Im doing wrong any help as always greatly appreciated.

Touching wood I think Ive solved it, two of my classes were my own modified versions of SPBitmapFont and SPTextField they worked fine as part of my old project but when adding them directly to the Sparrow project they must have caused a conflict somewhere as I had renamed stuff like SPNativeFontSize to myFrameworkNativeFontSize, there must have been something I missed.

In the end it was getting too messy and I just deleted those two classes and modified SPBitmapFont and SPTextField to suit my needs, without having to rename stuff like SPNativeFontSize and the errors have now gone and it compiles OK 🙂

I'm happy to hear you found the problem! Linker errors like that one give me a headache, too, when they pop up. Trial-and-error is unfortunately very often the only way to get to the root of it. 😐

Thanks Daniel I was quite lucky in as far as I had problems when I originally created it with stuff like SPNativeFontSize, so I had a suspicion it was something to do with that and it was the first thing I tried removing. The thing is Xcode and me don't always get along and I thought the error was something to do with the project settings or not adding my files in the correct way which led me to ask the question.

Not too happy with rewriting parts of the Sparrow frame work, its something Ive tried to avoid in the past but Ive documented the changes in case I have to revert at some point so Im a bit more comfortable with doing that now 🙂
