我很安静的编码新手，所以答案可能很简单。 我正在Xcode上开始一个新的C ++项目，我想从另一个任务中导入一个外部库：http://www.stanford.edu/class/cs106b/assignments/assn-0-narcissism-mac.zip
我想在新项目中使用libcs106.a库。当我手动将文件导入我的新项目，并开始#include库（如simpio.h）时，我得到了113个错误的长列表：

有人能让我知道我的节目有什么问题吗？
谢谢！ Ĵ
答案 0 :(得分：4)
编译器抱怨它在任何地方都找不到的类和方法。他们听起来都很熟悉，所以我相信你需要在你的Xcode项目中添加几个Mac OS X frameworks的引用：
Carbon.framework
Cocoa.framework
QuickTime.framework
您可以通过右键单击项目资源管理器并使用“添加/现有框架...”命令来执行此操作。
您可能更愿意使用assignment 0 source code for Mac作为起点，因为已经配置了包含的Xcode项目，链接到课程实用程序库并引用所有需要的框架。
