A fast, easy to use, free, and community supported 2D game engine
I have a game i am finishing. I am compiling it using 4.0 and setting the target to 3.0.
It starts running (see the default.png) and then i get the following:
dyld: Symbol not found: __NSConcreteStackBlock
Referenced from: /var/mobile/Applications/CCA0A44C-5A57-4C72-B59B-CF4AC9250E60/Puff Puff.app/Puff Puff
Expected in: /usr/lib/libSystem.B.dylib
Do you know what do i have to do in order to solve that? :(
Thank you VERY VERY VERY much!
That was the problem indeed, i didnt change the minimun target OS from the cocos2d library.
Hm, I embedded an image in my last post but it was stripped. Oh, here it is: http://img.ly/1XvL
Hi opetopic
Go to Targets in your project, select cocos2d libraries, then get info on it. Make sure the build settings are the same for your project and the library and it should work. It's often compiling optimized (Armv7) only, not standard (Armv6 Armv7).

Hm, ok. Then the problem is that I am not using a cocos2d template. I was already half way into a game when I decided to experiment with cocos2d, so I just branched my git repository and dropped the cocos2d source into it (well, initialized a git submodule technically).
Is there something I can do in this situation?
Thanks for the help.
I just figured this out. For others having this problem, this comes up because of the references to blocks in various parts of the cocos2d code. Even if your code never executes a block you will still get this crash on 3.X devices. So, you just need to add the -weak_library /usr/lib/libSystem.B.dylib linker flag to your build settings, or you can just do:
1.) Add the libSystem.B.dylib framework to your project
2.) Double click your target
3.) Go to General Tab
4.) Set libSystem.B.dylib to be weakly linked in the "Linked libraries" section.
Note that this problem only arose because I am NOT using the cocos2d templates and because I am building for iOS 4.0. If you are using the templates you should do what was mentioned above.
Hope it helps someone.
opetopic, this helped me. Thanks!
I got this error because I am using a cross-project reference to cocos in my project. I changed the cocos base and target settings to match my project but I still got the runtime error on 3.X devices. The weak link fixed that.
