Errors With AppKit

[Nick]

I'm trying to make an app using the Ogre framework after finally compiling it for 10.3.9, but I'm getting a lot of errors with the AppKit framework:

Any ideas how to get rid of all of that?

Looks like you're including Cocoa in a file that doesn't end with .m. :)

possibly due to this:

Thanks for the ideas, but I don't have any precompiled headers, nor am I explicitly including AppKit. I'm using Ogre and SDL which is why it's referencing AppKit, but I'm not sure where it is doing this. I have SDLMain.h/.m in my project, but that isn't solving it either.

I had a similar problem a few weeks ago. I wasn't using pre-compiled headers but was getting similar errors in AppKit.h. In the end it seemed to be GCC_PREFIX_HEADER was getting a wierd setting.

Here's a link to the thread, http://www.idevgames.com/forum/showthread.php?t=12222

it might be relevant here too. Check your targets Prefix Header setting doesn't have an unexpected setting. Mine was $(SYSTEM_LIBRARY_DIR)/Frameworks/AppKit.framework/Headers/AppKit.h for some reason?
