I have been struggling with Sparrow issues since day 1.
The most annoying thing is that my app worked well yesterday, and today: Broken
The latest beauty is a raft of linker issues. e.g.

"_OBJC_CLASS_$_SPPoint", referenced from:
...
And a whole heap of similar messages.
I have searched this site extensively to no avail.

Any tip on what to check would be appreciated:
This is what I have done/tried so far:
SPARROW_SRC is set to: /Dev3rdParty/sparrow/sparrow/src in Xcode->Prefs->Source Trees.
Other Linker Flags is set to -ObjC + -all_load in the MainProj and the Target.
libSparrow.a is (now) black in the Groups and Files list.
I have changed my Place Build Products in: back to Project Directory (just in case that was an issue).
And I Clean All dependancies after every config change.

Question: What should the "Path Type:" be for the Sparrow.xcodeproj? I have it set to "Relative to build Product" but have tried others.

The biggest annoyance. Sparrow behaves in another app that I compile, but has been broken in this one.

AAAAAaaaaaggggggghhhhh!!!!!

Thanks for your help.

I had linking problems with the sparrow.a library too so now i avoid all problems by adding all the sparrow project file sinto my project itself.

Open Project
Create New group called "Sparrow 1.0" (or whatever version your using.

Now go to your sparrow download and in
Sparrow
-sparrow
--src
---Classes
Select all the files in there and drag them into the xcode into the group your just made.
you can choose weither to add them to your project folder or not, i mostly don't but then you must remember not to move the sparrow folder the files are in.

Now you can just link to them and use it as normal like you would any other custom classes/files in your project.
NOTE: You'll probably want to remove the references to the sparrow.a library as you're now using the files directly.

Hope this help's.
It's not ideal but removes lots of the room for error in the other method and is how i work with it.

(also using a sparrow.a library you can't edit the source but can when using it directly, though unless you copied the files into your project folder you probably don't want to fiddle with the only copy of sparrow source you have on your computer)

Freerunnering.
Thanks for that, I had eventually got around to that solution. But it is not the way that the library is supposed to work I think.
Anyway, can at least I can get on with some work now.
However, I would still like to know what the CORRECT solution to this issue is.

Hi Linasses,

sorry to hear about those problems! The source tree variables are unfortunately a little tricky in Xcode ...

The most frequent problem is that your path has some spaces in it somewhere. If that is the case, put your path in double quotes. Could you check if this is the case?

I wanted to bump this old post because I'm facing the same issues when trying to build the AppScaffold project. I would like to 'properly' fix it instead of using the workaround.

When trying to run the scaffold project, the build fails and I get 17 of those linker errors.

The error is defined as : Apple Mach-O Linker Error, followed by "_OBJC_CLASS_$_SPTextureAtlas", referenced from:
Objc-class-ref in Media.o

and is repeated another 16 times with different classes and references.

My source tree is set as specified in the how-to and the Demo project actually compiles and runs just fine.

Any help is appreciated.

Do you have any spaces in your source tree path? That has lead to problems in the past!

Nope, no spaces in my path!

Have you tested it's the correct path (with no typos?)

For testing: You could copy the path from Xcode and jump to this folder via the Finder (Menu "go to folder" or what name it is)

I did indeed test that. However, after making a clean installation of XCode and re-downloading the sparrow framework, I managed to get everything working by following the steps. I'm not sure what it was but in my attempt to fix it I must've messed something up and couldn't figure out what..

Success at last
