cocos2d will not run, numerous errors in default code

Hello all,

I recently started up Xcode, after having been away from programming for a while, and encountered a load of errors.

There are currently 49 errors (and 1 warning) in the default cocos2d code for a Box2D app, found in four files:
-GLES-Render.h
-HelloWorldLayer.h
-AppDelegate.mm
-RootViewController.m

Here are some of the most common / salient errors:
-In GLES-Render.h: "Expected * before *..."
-In GLES-Render.h: "ISO C++ forbids declaration of *..."
-In HelloWorldLayer.h: "Cannot find interface declaration for 'CCLayer'..."
-In AppDelegate.mm: " '*' was not declared in this scope..."
-In RootViewController.m: " '*' undeclared..."
-In RootViewController.m: "Semantic issue: use of undeclared identifier 'CCDirector'..."

I've already attempted reinstalls of both cocos2d and Xcode, to no avail. Might anyone know what's going on here?

Thanks,
---Doc Incognito

looks like it can't even find cocos2d lib
maybe you did not even have the template setup correctly

Thanks for the suggestion. Unfortunately, after reinstalling 1.0.1, the code did not run, following much the same pattern (though now with 45 errors and 1 warning.)

Any other suggestions?

Thanks,

Sorry, can't help... with limited information
are you using the latest xcode?

I think RootViewController.m needs to be renamed to RootViewController.mm.

@greamer: I'm running version 4.1 of Xcode, and 1.0.1 of cocos2d.

@nathan: You're right, I did have it named incorrectly, though the build still failed in the same manner

Is it possible that I accidentally edited and saved a code file that doesn't reset from project to project?

Thanks Nathan, fixed my issue by renaming it the extension to .mm as well for RootViewController.

But my question is why didn't Xcode 4.1 pick this up before?

Argh, I tried upgrading to the cocos2d 1.1 beta, but it's still crashing in the same way.

I hate to bump this, but I do really need to get this working, and I'm not sure where else I can turn. I'm using cocos2d for an independent study of mine, on a lengthy project continued from last year, and while I work on my own time, I need to report progress to a teacher, but I have nothing to show.

If anyone has any further suggestions, I'd greatly appreciate their input.

Thanks,

sounds to me like you implemented a load of code using cocos2d v0.9, then installed the latest cocos2d v1.whatever?

If so, you need to replace all of the deprecated code so CCLabel becomes CCLabelTTF and so on...

@callaght: The strange part is that, just upon creating a new project with unaltered Hello World code, I'm finding about 50 errors.

well... maybe the best way is
force your way through... :P
fix all those errors manually :P

Which iOS version is your deployment target and are you using the armv6 or armv7 architectures (or both) in your build settings?
Not sure if that really has an affect but might want to check it out.

Hi @Doc Incognito, are you using Hello World code from your cocos2d v0.9 days or are you using a brand new Hello World that comes with cocos2d v1.0.1?

@Duckwit: I'm deploying for iPhone 4.3, and sorry, I have no idea what armv6 or armv7 are :(, and I'm not entirely sure where those build settings are.

@callaght: It's a brand new project in 1.0.1

Thanks,

Are you sure it is 1.0.1? I don't think you can use the same './install ...' command in terminal to install them, because they are Xcode 4 templates. (Or are they?)

AHA - http://www.cocos2d-iphone.org/archives/1412 <- You need to use that one for Xcode 4 ;)
