I have included restkit in project and when i build restkit, it builds successful. But when I build project, it gives 6 errors:

kindly help how to rid it off
Make sure your project is using the Three20 library. Also make sure your build order makes sense - you may need to reference three20 in your workspace/project before RestKit is compiled or in the RestKit project if you have one.

I have a running cocos2d project and a running ios storyboard project that both run without errors , when i try to embed cocos2d project into the main project i have the following errors (After disabling ARC and adding required frameworks ):

Add the libz.dylib library to the Link Binaries build phase or add -lz as other linker flag in Build Settings. Both will ensure the app is linked with the zip library needed by cocos2d.
I tried running a basic opengl program from this link. I can run it successfully. Now I need some functionalities of opencv to be added in this.
So I added opencv framework from this link.
After adding the framework I changed the files to .mm and its compiling good. The problem comes when I add "cv::Mat Variable". I get the below error. What would be the reason for this?
The below is the error I get When I add "cv::Mat Variable".

This Solves my problem. To add add opencv library file
AVFoundation.framework
ImageIO.framework
libz.dylib
should be added. And this link explains clearly about this. http://aptogo.co.uk/2011/09/opencv-framework-for-ios/
I am developing an app that saving an url using coredata.I am defining NSManagedObjectContext,NsManagedObjectModel,NSPersistentStoreCoordinator in CoreDataRepository object class instead of AppDelegate.I am saving this url using reference of CoreDataRepository.I am getting below error.

Any idea about this error.Thanks.
The linker can't find your CoreDataRepository class. Look in your target's Build Phases and add that source or library to either the compile or link phase, depending on where it's defined.
I am trying to compile the sample iphone openssl created by x2on here:

I've been trying to troubleshoot this for a day or so and I am stumped on what to do.
I can provide more information if needed.
According to this site, it indicates that you need to link with libcrypto.
I just figured out why it wasn't working. I never included the shared libraries in the same folder as my project and never linked the header search paths. After cleaning up my project and rebuilding it recognized the Openssl library and it compiled.
Good Day!

Make sure you added Three20:extThree20JSON+YAJL or Three20:extThree20JSON+SBJSON to your project (either manually or via ttmodule.py), also make sure they compile fine (look if the binaries are not red in your project Build Phases).
