I am trying to build with xCode 6 and I am getting this error:

I’m having a similar link issue the only thing is that my link error only happens when I add
bool onTouchBegan(cocos2d::Touch *touch, cocos2d::Event *evt);
I’m using Xcode 6.0.1 and Cocos2dx 3.0.

Undefined symbols for architecture x86_64:
“HelloWorld::onTouchBegan(cocos2d::Touch*, cocos2d::Event*)”, referenced from:
vtable for HelloWorld in HelloWorldScene.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Okay, I’m an idiot: i forgot the HelloWorld:: prefix.

Dear Batymahn, I have the same problem with you. Could you please describe your solution in detail? Thank you very much!

I forgot to type: “HelloWorld::” before the implementation method. For example,

void HelloWorld::touchesEndded(Event *evt)){
}
