c++ - 在 xcode 中导入外部库

c++ - 在 xcode 中导入外部库 - C++

转载作者：太空狗更新时间：2023-10-29 21:07:46

我在编码方面是一个安静的新手，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时，我开始 #include 库(如 simpio.h)，我得到了 113 个错误的长列表:

有人可以告诉我我的程序有什么问题吗？

谢谢!J

最佳答案

编译器提示找不到任何地方的类和方法。它们对我来说听起来都很熟悉，所以我相信您需要添加对几个 Mac OS X frameworks 的引用。在你的 Xcode 项目中:

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。

您可能更喜欢使用 assignment 0 source code for Mac作为起点，因为包含的 Xcode 项目已经配置好，链接到类(class)实用程序库并引用所有需要的框架。
