[解决了]
我从 cocos2d+chipmunk 模板中复制了花栗鼠文件夹结构并构建好了。
- “src”文件夹的类/Chipmunk/include/src
- “包含”文件夹的类/Chipmunk/chipmunk
感谢 Beta 提供的帮助。
:::::
我下载了花栗鼠 5.3.1 并尝试了一个简单的例子，但我收到了这个编译错误：

我不确定是否要正确添加 Chipmunk 库，我必须包括哪些来自 chipmunk .tgz 的来源？
这是代码：
ChipmunkTestViewController.h

UIImageView *barra;
UIImageView *esfera;
cpSpace *space;
}

void updateShape(void *ptr, void *unused);
@end
ChipmunkTestViewController.m
#import "ChipmunkTestViewController.h"
@implementation ChipmunkTestViewController
- (void) configurarChipmunk {

// Create esfera Body
cpBody *esferaBody = cpBodyNew(50.0f, INFINITY);
esferaBody->p = cpv(160,250);
// Create esfera Shape

esferaShape->collision_type = 1;
cpSpaceAddBody(space, esferaBody);
cpSpaceAddShape(space, esferaShape);
}
- (void) delta:(NSTimer *)timer {
cpSpaceStep(space, 1.0f/60.0f); // Refresh Space info
cpSpaceHashEach(space->activeShapes, &updateShape, nil); // Refresh Shapes info
}

cpShape *shape = (cpShape*)ptr;

return;
}

} else {

}
}
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {

barra.center = CGPointMake(160, 350);
